This is something I have source more frequently than I care to remember—not just from my film students at UCLA, but also from professional shooters who have attended my camera training seminars around the country. When shooting a project on film, camera Testing their new camera were a given. They were not something a DP would even have to request. Camera tests were budgeted and scheduled into the Testing their new camera period of a movie, even if a DP knew a film stock like the back of their hand. Why bother test them again and again? The answer is that you are not testing the acquisition medium; you are testing the interrelationship of three separate elements: Knowing your imaging device is only a small part of being able to achieve your desired look. You need to understand how your source imager will interact with your Testing their new camera in trying to achieve said look. In the days of film, several film stocks some known to you, and some Testing their new camera to your vocabulary would be tested through learn more here lenses, with several filters, through several lab processes, to see how they reacted when photographing your actors, in hair and make-up, in their costumes, and possibly even on Testing their new camera actual sets of your final shooting environments. You would then sit with a color timer and evaluate which stocks, lenses, filters and lab processes would get you closest to your desired final look. These principles have not disappeared simply because we are transitioning away from film onto digital acquisition. If anything, the interplay has grown exponentially more important, since our list of variables has easily quadrupled. Photograph by Steve Beres. Sure, you agree that testing this interrelationship is important. Spread ass babes Nude big boobs on glass shower.

Testing their new camera

Are the people looking morbid and ashy? Are they looking like orange pumpkins? Looking for the path of least resistance here. Good-looking skin tones are your guiding light; try to get to as close as possible Testing their new camera your ideal color palette while only using primary color correction adjustments. If you can get 70 percent there, it should be a breeze here the final 30 percent using the rest of the available toolset during final color.

What kind of image dynamics does your look require? Does your film take place under mostly overcast exteriors, or in a Testing their new camera with Testing their new camera walls and costumes and very little contrast? Or is it a horror film with lots of shadows and bright shafts of light, requiring a high-contrast look?

Mlif tube Watch Video Shemale pornstar. Take a few macro shots, keeping your lens at the widest angle as most manufacturers recommend. Photograph colorful subjects to see how the camera handles a variety of colors. While a LCD itself may have no bad pixels visually, check if any show up in photos. Also check if the actual LCD has a color cast as opposed to improper white balance in a photo. A digital camera may emit sound when it focuses, when the lens is zooming in or out or when continuous features such continuous Image Stabilization are enabled. I will take further test shots but if confirmed I am obviously concerned about malaligned optics. If the latter is the case, may I assume that this problem can be corrected? If so, is this best done by Nikon or are you aware of any companies that specialize in lens alignments. Thanks again. That definitely doesn't sound like something you are going to be able to correct with contact lenses or split filters! Your options are sending it back to Nikon or sending it to your local camera repair store depending on where you live, there might be one. There are a few repair places in New York City and you can certainly call them and ask if they have the capability of fixing that repair. Also, check your warranty paperwork from Nikon and give them a call to see if you are still covered. You could contact repair centers in other towns to see if they work through the mail Hi Todd: Thanks for a very helpful article. I have a question: Secondly, great question! There is no right or wrong here, but I just checked my LR and I go to 1: You can get closer, but my feeling is that, if you zoom in more, you'll only be racking up credits for a graduate degree in Pixel Peeping and that degree gets you into even less doors than an MFA! Todd, I am following your procedures to conduct an experiment. The plan is to shoot both lens over their similar focal lengths at the 24, 35, 50, and 70 for each f5. The question that remains is the focus method. Do you rely on Auto focus? If so are the lens auto focus "fine tuned" using the custom function III Fine tuning your Autofocus lens for each lens? So, for auto focus lenses, I usually use the auto focus when doing the lens tests. If I get an un-sharp image at sweet spot apertures, then I would speculate that I had an AF error, or kicked the tripod. My recommendation would be to test both lenses with auto focus on. If you don't get good results, try a round with manual focus and, yes, I would recommend Live View to assist with accuracy there as the days of awesome split prism focus screens are mostly gone. The target image is only 72dpi, if i would print this the quality in not very good. Is not possible upload a dpi version? The original file is the same dpi It should be sufficient for testing. The well known ISO charts can be found online and they are at similar resolution in. Thanks for the great article Todd. I have an old Nikkor 50mm 1. This 6 element lens seams to be sharper in the mid aperature ranges than my 7 element 50mm 1. Do you know anything about this 50mm 1. I have one on my Nikon FM3a all the time and have used it on my digital cameras as well. I am sure the new G versions are great, but that older pancake lens is really fun to use and a perfect size! There are a lot of different software options for viewing test images, including the default software that comes with most systems. I personally use Lightroom or Photoshop, but those are powerful programs that aren't required for simply opening test shots and zooming into them to check image sharpness. This probably applies if you have a camera full-frame , but still, if you have an APS-C, this lens will be an excellent investment. Depending on the country, the price ranges between and dollars, so it is an excellent choice if you manage a budget. This lens will allow you to achieve images that kit lens can not perform. Having an opening of 1. Definitely an excellent choice. They are somewhat more expensive, but worth every penny by yabeshphotography. If I shoot again and again the same wall etc it's best as I can compare to lens shot 6 months ago. Hi, I really like this article thank you. So I am an amateur aerial photographer, and I have just replaced the standard lense on my drone to take advantage of a new lense that is suppose to be better with the new Sony sensor that came with this drone. After reviewing the data, it's almost like there is no difference. I have not applied your testing concept yet, and most of the shooting that I do, I do with the default setting on the camera which are quite good. Will the focus chart make a difference on these small lenses as well. Thanks, Peter. My guess is that the chart will work just fine for your drone camera. Let us know if it works out for you! Good luck! I'm brokenhearted. I just received my new Canon 2. Wow, it IS sharp, the sharpest lens I've looked through. The dilemma is the awful vignetting at 50mm. The lens is going back.

In the basement of a building? If your script calls for dark and moody scenes, lit by moonlight or candlelight, you know that a large portion of your frame will be dark. You need to know how your chosen camera performs in dimly lit environments. Photograph by Andrew Ng. For this test, find a small space with plenty of objects and detail in it. This can be an office, a broom closet, or even your bedroom. Light a couple of candles and maybe a very small practical desk lamp if the room is large enough to absorb that light. Have someone walk through this environment in dark clothing with a flashlight on. Have them occasionally shine the flashlight at short distance to certain objects, and then occasionally shine it right into the lens as if searching for something. DaVinci Resolve again. This is a measure of signal-to-noise ratio. But at what cost to the noise floor? Incredible low-light performance is great and exciting, were it not for the issue of dynamic range. Bumping up the ISO to astronomical levels does not increase effective dynamic range. It simply raises the exposure floor—hence my inclusion of the flashlight. Look at how the objects react to being lit by the flashlight in relation to the noise floor in the shadows. This is very telling, since most low-light scenes will have occasional specular highlights that need to be handled. This is especially true for nighttime exterior scenes cars driving by with headlights on, signal lamps, storefronts. Why shine the flashlight into the lens? I do this for two reasons. First, it gives me a sense of how the lens will flare for a given sensor. Every sensor has a different OLPF optical low pass filter , which, in combination with the coating surrounding the sensor, will produce different flare effects given the exact same lens. This happens when a bright highlight like the sun inverts and turns black on screen. This mostly happens on lower-grade cameras and is somewhat fixable in post, but shining a flashlight right into the lens will reveal this problem early and alert you to additional work in post. Are these tests fully comprehensive?.

Testing their new camera I have done very elaborate and complex dynamic range testing over the Testing their new camera. Most cameras today can safely record nine stops of dynamic range.

If your movie calls for affinity in contrast and the lighting can be controlled throughout, I would skip this process. Schedule this test for when it is brightest outside. Find a window in an apartment or office that looks out onto something with lots of detail. It can be another building, a storefront, mural, anything with fine detail. Bring a friend and ask them to stand next to that window. Not in front of the window, but next to it, so you can see outside the window clearly and have the person to the side in half of click frame.

At this point, Testing their new camera to recreate the dynamics you expect to have to support in your film.

Is it 10 stops of dynamic range? Whatever you expect your biggest challenge to be, test it here. This can be done in two Testing their new camera. My preferred way is using a spot meter.

Hope your Testing their new camera lens Testing their new camera well for you. Set focus to center point focus. Then focus ensuring that your auto focus hits the center of the page with this chart I would aim right at the ruler.

Take the photo and review. Repeat for valid sample group. If the auto focus is correct the sharpest part of the image will be 10 on this chart on the ruler. If you camera allows it you can then set micro focus adjustments until it's spot on. I have a Sigma 1. Thanks for the article.

I have a question on sharpness: If so, is Testing their new camera anything that can be done to fix them? Yes, lenses Testing their new camera become "less sharp" over time. Are any of these the culprit for your lens?

Make a few simple tests to make sure your new digital camera is functioning correctly and free of problems. Many merchants let you return a faulty camera without penalty for up to two weeks from the purchase date. So give the camera a good workout before the time runs out with the seller. The best way to test a new digital camera is simply to give it a good look-over and take pictures. Do so before making any major changes to the factory default settings! Not the worst idea, but I would hope to find one with some signage on it to give me some sharp edges and lines to look at in the images. If you can do it, I recommend the test target for normal around 50mm and telephoto lenses greater than 50mm and a wall or bookshelf for wide-angle lenses. Many of us have a camera bag full of zoom lenses and prime lenses. If you have only one prime fixed focal length lens to test for sharpness, your mission is simple. If you have a quiver full of lenses and many of them are zooms, you will thank me later for that suggestion to get paper and pencil ready. For a normal or telephoto prime lens, I simply set up the tripod and camera at the distance where the target fills the frame, and then I take photographs as I run through the aperture settings. When out doing non-lens-test photography, I adjust my aperture in full stops to simplify the exposure math for me. I do the same for lens testing. If you adjust your aperture in half stops or third stops, you will get two or three times the number of test images to sift through and that might be enough to make this process less fun. For zoom lenses, I roll through each aperture setting full stops again at the focal lengths marked on the barrel, which usually correspond to popular prime lens focal lengths 85mm, mm, mm, etc. Of course, I will always test the zoom at the widest angle and the greatest, as well, even if they do not correspond to popular fixed focal lengths. This is where a little planning helps. You can mount each 85mm lens and roll through the apertures, but, before you move your tripod you might want to grab the mm lens, set it to 85mm, and test at that focal length. Take notes. The image metadata will help remind you what you were doing later, but it is good to have a check-off sheet tracking your progress, so you do not waste time by repeating tests. Also, if you are testing older, manual focus, pre-electronics lenses, your notes will help you when and if the metadata does not recognize the lens or aperture setting. When I test my manual focus lenses, I try to set up the test so that the targets fill the frame, while allowing me to focus the lens at infinity in an attempt to eliminate focus errors. Well, you just took several dozen pictures of a test target, bookshelf, wall, or city scene. Now you get to spend some time in front of the computer analyzing the data. I start by re-naming the files with the focal length of the actual shot, and the aperture plus the name of the lens. Then, when finished, I can easily compare the shots from a certain lens or a certain focal length by opening just those images on my screen. Still got your paper and pencil handy? Open a series of images single lens or single focal length and start comparing the visual sharpness of the center of the images and the corners. Take some notes. You can also evaluate the images for vignetting and symmetry, as well. For symmetry, verify that the lack of sharpness in the corners is the same for each side of the lens. For vignetting, you can push the contrast and levels sliders to see if the corners darken. When I compile my notes, I type them up and send the file to myself in an email, saving the notes on my smartphone. Mission accomplished. Let us know if you have different proven techniques or questions. Thanks for reading and good luck with your do-it-yourself lens tests! This is a fine article. I set the at 18mm. I am wondering, due to a comment in one of your responses: I shot landscapes always on a tripod and at f8 and up. Is this because I shot at f8? You hit the nail on the head here in many ways. The Zeiss 18mm is likely sharper at wider apertures than the Nikon as prime lenses have that advantage over zooms. Also, you could see a difference in distortion and things like chromatic aberations as well, but sharpness at mid-apertures will always be close. Great article. Your help would be appreciated. I would speculate that there is an issue with the electronic connections between the lens and camera. Sometimes you can clean them up a bit with a pencil eraser or by using other means, but usually the connections work or they don't. This seems like a specific failure. I would try to clean your contacts and then, if it bugs you a bunch, send it in for repair. If the lens is optically performing and the aperture and focus are all good, I would be tempted to ignore the metadata coming off the lens. If a lens will not focus properly at the infinity marking, does this mean the lens doesn't fit far enough into the camera body or just the opposite? Are you saying your lens will not reach infinity focus? Meaning, when focused at the infinity mark or beyond , distant objects like stars and planets and mountain ranges are still blurry? Many lenses focus past the infinity mark, so be sure you haven't passed infinity and started to defocus on the backside of that "distance. For more on infinity focus, check out this article: Thanks for this great article. I will take further test shots but if confirmed I am obviously concerned about malaligned optics. If the latter is the case, may I assume that this problem can be corrected? If so, is this best done by Nikon or are you aware of any companies that specialize in lens alignments. Thanks again.

My webcam can also record sound Why not just shoot with a camera that has a color palette that already closely matches the visual intent of your story? Armed with your lookbook, bring in friends, family, PAs and stand-ins that have mostly similar skin pigmentation to your lead actors and actresses. Surround them with as many color swatches that match your chosen color palette as you can find. These are quite literally loose pieces of fabric that you can find in the garment district for a few dollars each. It runs on reasonably cheap hardware and is fairly easy to learn. I then use only primary color correction controls to balance the skin tones and make them look healthy. Those controls are best left for final color. Once the skin tones fall nicely into place I move my focus to comparing the surrounding color swatches, and how they differ from camera to camera. When I desaturate the skin tones, do the other colors look too muted? If I make the skin tones warm and healthy, are any of the other colors now overly saturated and losing detail? As I dial in a color look, how are my skin tones fairing? Are the people looking morbid and ashy? Are they looking like orange pumpkins? Looking for the path of least resistance here.

Most Testing their new camera the time the corners weren't as sharp as the center of the image, but occasionally a camera took photos where the center was blurrier than the rest of the image. To test the lens uniformity, I printed out several pieces of paper with letters on them at various font sizes.

Written by Digicamhelp Editor. Share this: If you want to get crazy, you can spend a lot of money on laser-etched glass targets that are used for calibrating things that are way more precise than your camera and lenses. A printed test target will be your least expensive option. Some folks will make a homemade diorama with different objects wine bottles, color charts, tourist trinkets to photograph in one scene. This is fun and works well for the test, but the problem is, unless you have very understanding roommates or the only key to your photo cave, you will have to put all the objects away when you are finished and you might not be able to recreate it perfectly in the future. The two-dimensional test target gets put away into the closet when I am finished. Do you need a dedicated target to perform a lens test? Well, trees move when the wind blows. Remember what I said about eliminating variables? When I do a lens test outside, I look toward manmade structures usually stuff that humans make has a ton of right angles and sharp edges and I try to put lettering of some sort street sign, license plates, storefront signage in the center and corners of the image. Remember, you are testing your lens, not creating the greatest photograph on the planet, so don't worry about composition and all the other things that you might usually consider before taking a photo. Also, you want the things you are going to study in the image to be as close to equidistant from you as possible. When shooting a target on a wall, level your camera and aim for a vertical wall. When outside, try to find a wall or scene in the distance that will have the center and edges of your frame about the same distance away. I have found that a well-populated bookshelf is a great tool for lens testing. Remember what book you are targeting in the center of the frame and use the writing on the spines of the surrounding books to check your sharpness. Also, the shelves, if straight, can let you evaluate lens distortion. Not the worst idea, but I would hope to find one with some signage on it to give me some sharp edges and lines to look at in the images. If you can do it, I recommend the test target for normal around 50mm and telephoto lenses greater than 50mm and a wall or bookshelf for wide-angle lenses.

Also, you could see a difference in distortion and things like chromatic aberations as well, but sharpness at mid-apertures will always be close. Great article. Your help would be appreciated. I would speculate that there is an issue with the electronic connections between the lens and camera. Sometimes you can clean them up a bit with a pencil eraser or by using other means, but usually the connections work or they don't. This seems like a specific failure. I would try to clean your contacts and then, if it bugs you a bunch, send it in for repair. If the lens is optically performing and the aperture and focus are all good, I would be tempted to ignore the metadata coming off the lens..

Then I posted them on a wall and took a photo of them. It's easier to judge the sharpness in a photo that's showing text rather than scenery. When performing this test, blurriness in the photo could also be the result of a misaligned lens mount, as Michael Clark indicates in a comment:.

Such a test will also reveal alignment issues that could be caused by the camera's mounting flange being out of square with the camera's sensor. For cameras with in-body stabilization where Testing their new camera sensor moves on several axes this can be a common problem. Home Questions Tags Users Unanswered.

If you have a quiver full of lenses and many of them are zooms, you will thank me later for that suggestion to get paper and pencil ready. For a normal or telephoto prime lens, I simply set up the tripod and camera at the distance where the target fills the frame, and then I take photographs as I run through the aperture settings. When out doing non-lens-test photography, I adjust my aperture in full stops to simplify the exposure math for me. I do the same for lens testing. If you adjust your aperture in half stops or third stops, you will get two or three times the number of test images to sift through and that might be enough to make this process less fun. For zoom lenses, I roll through each aperture setting full stops again at the focal lengths marked on the barrel, which usually correspond to popular prime lens focal lengths 85mm, mm, mm, etc. Of course, I will always test the zoom at the widest angle and the greatest, as well, even if they do not correspond to popular fixed focal lengths. This is where a little planning helps. You can mount each 85mm lens and roll through the apertures, but, before you move your tripod you might want to grab the mm lens, set it to 85mm, and test at that focal length. Take notes. The image metadata will help remind you what you were doing later, but it is good to have a check-off sheet tracking your progress, so you do not waste time by repeating tests. Also, if you are testing older, manual focus, pre-electronics lenses, your notes will help you when and if the metadata does not recognize the lens or aperture setting. When I test my manual focus lenses, I try to set up the test so that the targets fill the frame, while allowing me to focus the lens at infinity in an attempt to eliminate focus errors. Well, you just took several dozen pictures of a test target, bookshelf, wall, or city scene. Now you get to spend some time in front of the computer analyzing the data. I start by re-naming the files with the focal length of the actual shot, and the aperture plus the name of the lens. Then, when finished, I can easily compare the shots from a certain lens or a certain focal length by opening just those images on my screen. Still got your paper and pencil handy? Open a series of images single lens or single focal length and start comparing the visual sharpness of the center of the images and the corners. Take some notes. You can also evaluate the images for vignetting and symmetry, as well. For symmetry, verify that the lack of sharpness in the corners is the same for each side of the lens. For vignetting, you can push the contrast and levels sliders to see if the corners darken. When I compile my notes, I type them up and send the file to myself in an email, saving the notes on my smartphone. Mission accomplished. Let us know if you have different proven techniques or questions. Thanks for reading and good luck with your do-it-yourself lens tests! This is a fine article. I set the at 18mm.

If the lens is optically performing and the aperture and focus are all good, I would be tempted to ignore the metadata coming off the lens. If a lens will not focus properly at the infinity marking, does this mean the lens doesn't fit far enough into the camera body or just the opposite? Are you saying your lens will not reach infinity focus? Meaning, when focused at the infinity mark or beyond , distant objects like stars and planets and mountain ranges are still blurry? Many lenses focus past the infinity mark, so be sure you haven't passed infinity and started to defocus on the backside of that "distance. For more on infinity focus, check out this article: Thanks for this great article. I will take further test shots but if confirmed I am obviously concerned about malaligned optics. If the latter is the case, may I assume that this problem can be corrected? If so, is this best done by Nikon or are you aware of any companies that specialize in lens alignments. Thanks again. That definitely doesn't sound like something you are going to be able to correct with contact lenses or split filters! Your options are sending it back to Nikon or sending it to your local camera repair store depending on where you live, there might be one. There are a few repair places in New York City and you can certainly call them and ask if they have the capability of fixing that repair. Also, check your warranty paperwork from Nikon and give them a call to see if you are still covered. You could contact repair centers in other towns to see if they work through the mail Hi Todd: Thanks for a very helpful article. I have a question: Secondly, great question!

Is your film very saturated and punchy, or does it have a dryer, desaturated vibe? What color tones are you aiming for: Steely blue? Or perhaps a warm amber look? If a distinct color palette is vital, you must set a lookbook with the help of all your designers production and costumes to make sure everyone is on the same page. Armed with this lookbook and palette, you can prepare your color test. The dirty secret is that you can get any camera to produce decent skin tones. Every camera has different color filter arrays on their sensors, and by extension, records into a different color gamut. What this means is that every camera will record the spectrum of available colors slightly different. Can they be color timed? Why not just shoot with a camera that has a color palette that already closely matches the visual intent of your story? Armed with your lookbook, bring in friends, family, PAs and stand-ins that have mostly similar skin pigmentation to your lead actors and actresses. Surround them with as many color swatches that match your chosen color palette as you can find. These are quite literally loose pieces of fabric that you can find in the garment district for a few dollars each. It runs on reasonably cheap hardware and is fairly easy to learn. I then use only primary color correction controls to balance the skin tones and make them look healthy. Those controls are best left for final color. Once the skin tones fall nicely into place I move my focus to comparing the surrounding color swatches, and how they differ from camera to camera. When I desaturate the skin tones, do the other colors look too muted? If I make the skin tones warm and healthy, are any of the other colors now overly saturated and losing detail? As I dial in a color look, how are my skin tones fairing? Are the people looking morbid and ashy? Are they looking like orange pumpkins? Looking for the path of least resistance here. Good-looking skin tones are your guiding light; try to get to as close as possible to your ideal color palette while only using primary color correction adjustments..

In the past, when I have gotten a new camera, I have just done a black test, or what Testing their new camera call a "cap test". You equip a lens, put on the lens cap, then take a series of exposures Testing their new camera the full range of possible ISOs in raw.

The resulting images will reveal any bad pixels or glaring sensor problems. However, I just got new OM-D M1 Link which for me is a fairly pricey camera, so I would like to do more testing than just a black test to make Testing their new camera it is ok.

What tests should I do? I have had some cameras with lens uniformity problems, where some areas in their photos were not as sharp as other areas.

Most of the time the corners weren't as sharp as the center of the image, but occasionally a camera took photos where the center was blurrier than the rest of the image. To test the lens uniformity, I printed out several pieces of paper with letters on them at various font sizes. Then I posted them on a wall and took a photo of them.

It's easier to judge the sharpness in a photo that's showing text rather than scenery. When performing this test, blurriness in the photo could also be the result of Testing their new camera misaligned lens mount, as Michael Clark indicates in a comment:.
