How to correct edges with high contrast?

I have been looking for a solution to edge correction for a long time. As all of you have noticed, SD and HD video camcorders are producing a "sharpening" or extra contrast in edges of high contrast. Here's a typical example (a part of a HD frame), where you can see the darker edge on the shoulders, arm and around the window frames.
My question is: does anyone know an (automated) way to correct this? An effect or a method for instance in After Effects? Please, let me know if you have a solution.

Hi again Todd,
thanks for the reply!
Well, yes that's obvious, but please, as you should have seen in the 
image (small part of a HD image), the image is shot with quite low 
sharpening adjustments in the camera!!!
As you also should know that this is a very usual problem, that cannot 
be totally avoided in the camera. So, please let me know any better 
ideas.

  • When slowly panning , objects or areas with high contrast , flicker / shake

    Hello,
    I purchased a canon 5d mark3 to use mostly as a video camera. I'm experiencing a very frustrating issue (I'm explaining it in more detail below).
    I've been in contact with canon repair facility and tech support  for the past 2 months (since I first purchased the camera. I sent the camera for repair already twice and both times I got the camera back after supposedly been “fixed” but the exact same issue is still there… I’m already frustrated and confused about this…  I haven't had an answer or a solution as today.
    I'm wondering if anybody else is having a similar issue. I did find some people online complaining of a similar problem but most of those pages are a year old or so. 
    I have been also researching and looking to all kinds of videos (specially at vimeo) where the 5d mark3 it's been used and even in more extreme and faster panning I don't see the same issue I'm experiencing.
    Some technicians at canon think it may be an issue with the lens ( 24 - 105 canon lens that comes with the camera).
    I did run all kinds of tests etc (even at B&H where I purchased it) with no luck .
    Here is a more detail description of the issue:
    The problem is that (even with a fluid head tripod) when slowly panning , objects or areas with high contrast , flicker / shake (most noticeable on white objects with daylight over a dark surface). This happens at 24 and 30 fps (not at 60fps) The technician on the phone mentioned that I should use higher shutter speeds (I was using 1/50 for 24fps and 1/60 for 30fps) I did try it with several shutter speeds all the way up to 4000 and the issue is even more noticeable. I tried with and without IS with the same result. I actually probably I already tested all the different settings always with the same results.
    I will appreciate any ideas or knowledge on this issue …also I would like to hear from other users with the same problem…
    Here I uploaded a few examples:
    https://vimeo.com/67316435

    Thanks

    Ok so really? nobody has nothing to say about it? why? nobody can see the issue? nobody cares? or is just uncomfortable?any canon tech reading the forums?

  • Photoshop - Fade is onion ringed with high contrast? - No true fade possible?

    Hi everyone, am I being totally stupid (possible) or can you just not get a true fade on a computer / Photoshop?!
    Any image I take, if I make the contrast high enough, the fade / vignette gets onion ringing. I paint with the most
    blurry brush, I can 'Blur' it ad nauseum, and it doesn't really change it. Is it a mode, I've tried Adobe RGB 98 and
    sRGB. This doesn't seem to be a common problem, but mabye people don't notice it too much? PLEASE HELP!
    Thanks!

    What you want to do is work in 16 bits/channel mode.
    With a good monitor and video card, you can see the distinctions between each of the 256 levels of grayscale.  This is also sometimes visible in nearly solid colors as well - such as skies.
    Video cards and monitors generally provide 8 bit/channel color, but they don't always maintain that all the way through.  Better ones do, and now we're starting to see the advent of 10 bit/channel pipelines, though that's not mature.
    What you see on the monitor isn't necessarily what's in the document, especially if you use deep data, as I mentioned above.
    From the sound of things, it seems as though your video card / monitor pipeline isn't providing very high bit depth at some point in the process.  As you were told in another thread (if I recall correctly) a poorly set monitor and a radical profile created by a calibrator to compensate could be involved in this.

  • How will Reflow work with higher resolution mobile devices?

    If the media queries are based on a resolution breakpoint, how will we be able to specify a mobile css design for new mobile devices with such high pixel density displays?

    I haven't found a workaround for device pixel ratio but I have found that creating my sprite at double res and oversizing my images helps greatly with sharpness on hi-dpi displays. Reflow does allow for CSS3 background sizing which is great for resizing a single  sprited item across breakpoints.
    SVG would be even better but OSX Mavericks has made illustrator unusable for the time being, so I'm using raster-only sprites.

  • How to Correct Names with Improper Spelling

    When I first "named" an individual for use in the FACES section, I misspelled her name. How do I correct that spelling, especially since I now have accumulated several images of her and don't want to lose the association of name to photo?

    Thanks. My error is that I had used a small letter rather than the capital letter in the last name. So, iPhoto did not recognize the change I was trying to make until I put a +notional word+ there too, and then changed the name one more time. Thanks.

  • How can I use the Windows 7 high contrast theme with CS6?

    I prefer using a high contrast theme in Windows, as I find it reduces eye strain, unfortunately these themes don't work in InDesign CS6 (i've tested Illustrator, Dreamweaver and PS and they seem to handle the high contrast theme ok, but this forum doesn't quite like it either, but that could just be because I'm forced to use IE at work here)
    Any text within dialogue boxes is black, and the toolbars and windows are pretty much unusable too.
    Is there any way around this issue?

    I see the same thing using a High Contrast theme. I think you're in uncharted territory here as far as what's been discussed previously on the forum, but maybe one of our other users also is a high contrast aficianado and has figured something out.

  • Clarity/shadows + distortion correction = terrible artefacts in high contrast areas

    common example (clarity and shadows +100):
    without distortion correction
    with distortion correction
    Raw file: nycz.info/temp/castle.dng

    The adhoc fix I'm using for images where it's causing problems is to paint out the problem areas with a localised adjustment brush with a very large hit of negative clarity. As most of the problem areas have been pretty small it's an easy fix, but I'd like to see the issue addressed before the final comes out as close examination has shown it up on quite a few images (reflective mike against black stage background, pier edges against a bright but cloudy sky, tree branches against the sky). I've also now set my default to having lens profile distortion off and only using it where I need it.
    Edit to add: Unfortunately on the image I'm working on at the moment, it only removes it as long as clarity is set to less than 50 - I need the lens adjustment to get the horizon flat, and I want the clarity, but if I try to have both I'm getting nasty white streaks along the pylons of a pier and it shows at screen size  let alone on prints or 100 per cent view.  With this particular image any amount of clarity over about 15 and the profile image adjustment is producing ghastly results, visible at small sizes.
    Edit again - urggggh. Manual adjustment to level horizons (beach images again) using lens correction plus clarity isn't good either. I've got rather a lot of those and basically can't use any amount of clarity or I start getting areas of light stripes along dark high contrast edges. However if i go to the crop and straighten settings,  and straighten there, it's fine.
    Edit again: Ok this is an app killer. Back to Lightroom 4.0 (If I can work out how!). Too many of my images are affected, and affected noticeably. What a shame as the defringing in RC2 is absolutely fantastic on long lenses, but this is affecting too much stuff.
    I'm getting it  on quite a few images I've done nothing to excepted converted them to LR4 - it's very clear on the before/after previews of PV2010 and PV2012. And the edges don't have to be that high contrast - I'm not sure if this screen shot shows it clearly enough but conversion gives a row of little white dashes along the green girder in the attached images Click on images to see them a bit larger- the first image shows small size before and after comparison with problem area highlighted - nothing done except change process PV2010 to PV2012; second image shows PV2012 magnified a bit. Turning off the enable profile corrections button returns image to PV2010 appearance. Removing  clarity  adjustment will also remove artifacting -  in this case it's the clarity that is mucking things up. I can get the same artefacts with clarity on zero and the shadows pushed up above 70. Clarity gives problems at much lower settings.

  • Best lens/settings for outdoor shots (high contrast) with 6D?

    I have a 6D I'm just getting started with. When I get a perfect shot (perfect lighting, color saturation, depth of field, etc), I LOVE it! The trouble is, I'm not getting enough of them. Not capturing what my eye sees with good repeatablilty. I have the following lenses for it: The 70-300mm zoom that came with it; a 24-105mm; a 17-40mm ultra wide angle; and a 50mm 1.4 fixed (dumb impulse purchase that I haven't found too useful). I am planning a trip to our tulip festival, and there will be loads of colors and likely high contrast as it will be a mostly sunny day with some clouds. PERFECT, right? Except I find that many times, particularly on my full auto settings, I am not getting the exposures I want! The photos often turn out kinda washed out, without the full saturation I want. And sadly, I'm just not able to compensate for that with the photo editing software I have. As I said, I'm just a beginner and don't want to lug around a manual with me to read while trying to get a good shot, so...anyone have any quick and dirty advice for which of my lenses will be the best to use for distance vs closeup of the flowers, and what settings to use with it? Full auto vs A, AV, or full manual? And if I use full manual, what priority do I want to get the best saturation? Urgh, I hope this isn't too crazy wide-open of a question to be able to get good helpful responses, it's hard to know what to ask. I just want to get some really good, color-rich, good depth and texture photos without a lot of thinking, lol. Thanks! PS-- I'm thinking of selling my 50mm and maybe one of my other ones to get a different one with better ranges. Any suggestions? I tend to do a lot of wildlife and landscapes, if that's any help, and find sometimes that the 300mm doesn't cut it.
    Thanks again!

    FIrst of all, it takes time to learn how to use a complex camera system well, so don't beat up on yourself a lot or give up on the gear you already have too quickly. Keep taking lots of photos, analyzing them and how you might have made them better. All cameras and lenses have their ideal uses and limits, it's just a matter of learning them and there's no substitute for experience. Get the book "Understanding Exposure"  by Bryan Peterson and read it, study it, learn it. That's the best single book every semi-serious to serious photographer who wants to improve their skills should read.... Might turn out to be the best $18 you ever spend on your photography. 
    The various exposure modes each have their uses. I see some people suggest using M (manual) only... but that's slower and limiting and there are times it will prevent you from "getting the shot". Av (aperture priority), Tv (shutter priority) and even P (program) all have their uses. I like to set my camera to M and forget it, but that's really only possible when lighting is very steady and consistent or I have time to carefully set up each shot.
    Much of the time I have to use Av or Tv because of variable lighting conditions. This can be because of intermittent clouds changing the intensity of light itself, or because I'm trying to capture shots of a subject that's moving in and out of different lighting. I tend to use Program when I just need a quick shot in different light than I've been working, and don't have time to calculate my exposure and am not very concerned about depth of field (aperture) or freezing or blurring subject movement (shutter speed). All three of these auto exposure modes (as Canon calls them) require experience with and knowledge of how subject tonality effects the camera's reflective metering system and how to use Exposure Compensation to correct for it.
    There's a "tool" built right into your camera that can help you learn about the exposure controls and how your choices with them effect your images.... On the top dial there's a "CA" setting, which is a great learning tool that will give you feedback on the LCD screen about your settings. This might take the place of carrying around the manual and consulting it before each shot. Try it!
    Personally I don't use the "SCN" or "Green Box/A+" modes, both of which are super auto exposure... That dictate a lot more camera settings than just exposure. These also limit focus modes, file types, color rendition, and more. Av, Tv, P are plenty of automation for me.
    A lot of your questions seem to be about lighting. If you ever watch a movie being shot or a pro making still portraits or macro shots, you are likely to see them using some sort of light modifiers.... reflectors to "bounce" more light onto a subject, fill flash to open up shadows, flags to block light, diffusers to reduce contrast and more. Monte Zucker was a master portrait photographer who specialized in available light (no flash) and made use of what he found on location and modifiers such as these... even invented a few of them. These are tools that you might use, or you can learn to look for similarly "ideal" lighting that's naturally occuring and will give you the effects you want.  For example, if shooting close-ups and macro shots of flowers, insects and such, I often look for light shade to work in... or pray for a moderately overcast day (all too rare here in Calif.). Same can be done with portraits and many other types of photography.
    To get great color in your images, you should get set up for and learn to do a Custom White Balance. This will insure optimal color in a wide variety of situations. Auto White Balance is very usable, especially in full sun. However, shade or indoors/artificial lighting comes in a wide spectrum of colors and can challenge AWB, or you might prefer it be rendered differently than the auto mode will do. There are a bunch of "preset" White Balance you might use - flash, tungsten, shade, etc. - but setting a Custom WB can very often  give more accurate results. There are WB targets (usually white or neutral gray) that can be used to quickly set up a Custom WB simply by taking a test shot and telling the camera "this is what you should use"  to set WB. There are even "warm cards", which are lightly tinted to cause slight bias toward a little warmer looking image, or in some cases cooler.   
    Shooting digitally, a lot of what you want to do can be, or might would even be better accomplished in post-processing..., i.e. at your computer at home. Today with digital photography we all are essentially our own "photo labs", too. More to learn, I'm afraid. There are various image editing and optimization softwares, as well as very helpful things like graphics quality computer monitors and calibration devices. It's hard to take your images to their "best" without some additional "development" at your computer. Shoot RAW for the maximum ability to make adjusments to your images in post-processing. This includes the ability to change White Balance quite freely. But a RAW file is sort of like a negative from the days of film... taking the shot is just the first step, the post-processing is necessary and an important part of creating the final image. (Note: Shooting RAW + JPEG is a good learning tool.... once you can make finished images from your RAW files that are better than JPEGs it's producing itself, you can stop shooting JPEGs at all.)
    Sorry, but you aren't going to be able to do this "without a lot of thinking"
    However, over time you will find that working with your camera and lenses... as well as everything else that's part of the process... becomes easier and eventually a lot of it will be second-nature. You'll need to do a lot of practice and study at first... and may feel overwhelmed at times. But gradually and eventually you'll  realize that you know exactly what to do to get the images you want in many different situations. Don't be too quick to change or add more gear, because that just means starting some of the learning process over again.
    With respect to wildlife photography, yes a 300mm lens on a 6D may not be enough reach a lot of the time. You have several possible solutions: get a longer focal length lens (Canon 400/5.6L is reasonably priced and quite good, but lacks IS so plan on using a tripod or at least  a monopod... Canon 500/4L IS is fantastic, but pretty expensive and quite large... think "tripod only").... Or, get a crop sensor camera (70D for example) to complement your full frame camera. The 300mm will "act like" a longer focal length, when used on a crop sensor camera.
    Be warned, though, small wildlife, birds and such, there is no such thing as a "long enough" telephoto. If you have 300mm, you'll want 400mm.... But once you get that 400mm, you'll want a 500mm, etc., etc. Eventually the lenses get very pricey and large, hard to hold steady and even shooting through a lot of atmosphere will reduce image quality. So other solutions you'll probably want to learn inlude stalking skills, use of blinds, calls, decoys, baits to bring subjects closer.  
    A lot of patience is needed too. There are times the subject is just too far away and all you can do is sit back and enjoy the show, hoping they'll come closer. Sometimes I've spent weeks or even months acclimating animals to allow me to approach close enough to get the shots I want (Canon EF 135/2L lens on Canon 7D)...
    Other times I've found locations where the critters are already relatively accustomed to people and will let me get close (EF 300/4 IS USM lens on 7D)...
    Hunger sometimes  outweighs shyness and fear, too (EF 300/4L IS USM on 7D)...
    While some wildlife could care less about you and may even give you repeated opportunities to get a good shot of them (EF 300/4L IS USM lens on 5D MkII)...
    Hope this helps!

  • How can I turn on the high contrast theme without the Windows Desktop being set to high contrast?

    Firefox 4.0 broke one of the best accessability addons that existed, AnyColor. Now I'm stuck with the closest I can get to it, a non-customizable theme which gets some things right but other things wrong.
    Naturally, I'd like to make my browsing as comfortable as possible to my low-vision eyes. I thought that the reported "high contrast" Firefox theme might help. Unfortunately, it seems that the only way to turn this on is to turn on high contrast themes in Windows-- and I have adjusted my Desktop so that I don't need them. Unfortunately that would seem to be the only way to get it in Firefox.
    Is there a secret way to force high contrast themes? The best solution for low-vision users, of course, would be to officially support AnyColor, or an addon like it.
    As an interim solution I'm using Purple Fox, which at least has the feature of being light text on a black background, and has visible tab close boxes; but it has fuzzy edges and twiddly graphics all over the place. It's not bad, it's just not really good. But having tried all of the themes with the word "dark" or "black" in the descriptions, it may be the closest to a working LV theme.
    Thanks for any help you might be able to give.

    NoSquint is certainly a nice AddOn, which does something helpful; but it doesn't enable high contrast themes, which is what the question was about.
    I have gone back to 3.6.16 in the meantime. I can continue to use AnyColor that way. The 4.0 upgrade seems to have more disadvantages than advantages.

    Thanks for the reply. To clarify, by "Firefox chrome" I am referring to Firefox's GUI, such as the tab bar, scrollable context menus and the contents of the 'about:' pages. As a point of interest, Chromium on Ubuntu recently started supporting touch-scrolling for web pages and throughout it's interface.
    dom.w3c_touch_events.enabled sends touch events to the webpage, which is less important to me right now. In fact, others have reported that in situations where Firefox has touch-scrolling, enabling that option breaks the touch-scrolling for webpages that listen for the touch events (hence the default being 'disabled').
    I'd really like to know if native touch-scrolling is possible under Linux as my current setup is functional but not ideal.

  • How do I make Firefox ignore the "Use High Contrast" option in Windows?

    I am taking care of a Windows XP machine which is running in "High Contrast Mode" for accessibility reasons. This display mode is enabled via the Control Panel of Windows (Accessibility Options, Display, Use High Contrast) and it has major impact on how Firefox display web pages. What I want to do is make Firefox ''ignore'' this operating system option, so web pages will be rendered "normally", but keep Windows in High Contrast Mode.
    Is there any way I can make Firefox ignore this setting? I.e. run Windows in High Contrast Mode, but not Firefox?
    A similar questions has been discussed here:
    http://support.mozilla.com/en-US/kb/Website%20colors%20are%20wrong
    However, I don't want to disable High Contrast for Windows and the whole machine, just for Firefox.

    John,
    thanks for your comments. The computer is mainly used by a visually impaired person. She doesn't do much web surfing though and doesn't really need a high contrast web browser. If however a colleague wants to help her maintain the machine or quickly wants to look up something on the web for her, then it would be great if it was possible to access web pages "unfiltered", in their regular look and feel, as designed by the web author. In fact, the High Contrast Mode significantly changes the way web pages look, and sometimes screen elements needed for navigation etc. are suppressed or rendered invisible. (This, of course, is often related to poor web design, like graphical buttons or links with the actual label as a background image or without an ALT attribute, but unfortunately, vast parts of the web are not really "accessible", so accessibility will remain an issue for the browser as well.)
    Creating a separate user account certainly is an option, especially for shared machines, but it makes it more complicated to quickly jump in and give her a hand. That's why separate user accounts are not really popular here; instead, Opera was installed which does not adhere to the OS setting and therefore grants a neutral view to all web pages.
    Actually, when I started investigating on that issue, I was quite surprised that there was no option for this in Firefox, not even in "about:config". After all, Firefox obviously queries the OS for the Contrast setting and then chooses to render the page this or that way, so I thought they certainly implemented a flag or something to change the behavior. It seems however there is no such flag, is there? This distinction seems to be entirely hard-wired.
    I am not sure if this is the place for change requests, but if somebody stumbles upon this question, is there any chance to make this setting open to the public? Something like an option "accessibility.useoscontrastsetting" or so? This might also facilitate it to develop an add-on for on-demand switching between the two modes, and web designers could check more easily how their work looks for those with poor eyesight.
    Greetings,

Maybe you are looking for
