Brightness/Contrast problems

I've noticed when I watch some dvds on my comp that the dark areas are much darker than they should be, sometimes to the point that I can't make out characters that are on the screen, these are parts that are clearly visible on a normal tv.
I've been to 2 websites that show value gradients for calibration, and I noticed that between 0 and about 15 percent looks completely black, so I'm losing that much value range in those areas.
When I calibrate the screen, if I brighten it to see the dark areas then the brights become far too bright. When I go into the calibration it shows the apple that you're supposed to match up with in value, when I do all that the screen becomes much too bright again.
I'm using the sRGB 2.1 profile since it's the most widely used, the default eMac profile is also way too bright. Also, in the first step of the calibration it says to adjust the brightness and contrast until the oval is barely visible, when I have these sliders all the way up as bright as can be I still can't see the oval, which makes the calibration process a little difficult when I can't even pull off the first step with accuracy.
Is there anything I can do about this?, is there an application that will help me adjust just the black point without making the whole screen brighter? Thanks in advance.

update
I found a shareware application called SuperCal that did the trick, I managed to keep the 2.2 gamma that pc users have while not making things too dark or bright, the black and white points are leveled out now so the gradient bars on test pages look good now. Thanks anyways guys .

Photoshop Levels/Brightness & Contrast Problem (PS CS2)

When I try to apply Levels & or Brightness & Contrast settings to an image, it always seems to revert back to the way it was. The filters won't do anything it seems. I have Adobe Photoshop CS2. At home it did the same thing and I re-installed Photoshop only to find out it still did not work. Is there something I am forgetting to do? Your help will be much appreciated!!!
Eric

View your image at 100% (Actual Pixels) when making adjustments.
(And I'm going to take a wild guess that you are working on a line drawing or scanned half-tone image.)

Brightness/Contrast Problem in CS3 & CS2

When I adjust (using legacy option) the sliders, then hit okay, the adjustments don't apply, and the image reverts to it's original state as if I hadn't adjusted the contrast or brightness at all. It did this in both CS3 & CS2. Has anyone else had this problem before?
My workaround was to make a B/C adjustment layer and then merge visible to a new layer, but it did the exact same thing. The new merged layer didn't have the B/C applied to it. This is very strange.

We should move on but calling someone rude because they misunderstood something and made a poor judgement is uncalled for.
Moving on I think that the advice to use curve instead of B?C would offer better control
As to why the adjustment layer you used did not have an effect as expected there may have been a small selection active when you invoked the layers adjustment everything seem to work but it is is only being applied to what might be a very small selection. Perhaps one you are accidentally creating. Check to see if you have a selection tool active and watch how you are moving the cursor.
I hold the stylus in a funny way and sometimes make a selection and swear i am not touching the tablet with the stylus but on more careful observation or by just hitting escape or command D and then making the adjustment all is well.
This might not be your problem but it is the only one I can think of at the moment.
if this is the problem keep in mind this is not really a photoshop problem or solution and an unlikely scenario, even though it is a possible one.
No one here would be expected to know this and of course it can be quite off base.

Applying brightness/contrast effect doesn't work

I have a project in the correct format on a properly formatted external drive. When I apply the brightness/contrast effect the red progress bar appears and the hard drive works for several minutes while the bar fills. But when it's over, the effect is not applied and the clip looks the same.
I have closed and restarted iMovie and tried again and I have trashed the Font Collections folder.
Any further help would be appreciated.

Like everyone else here, I'm just an iMovie user who volunteers to help answer questions.
Unfortunately, recent changes to the Discussion software introduced bugs that make it very difficult to reply to user questions. Despite assurances by Forum administrators, these bugs are not being fixed.
This is to ask that you contact Apple, suggesting that additional resources be allocated to fixing the Discussion software. Hopefully your support will encourage Apple to address these problems.

I plan to include this message in postings until the issues are resolved.
Have you tried disabling any third-party QuickTime add-ons or iMovie plug-ins installed on your computer? If something is messing up QuickTime that could cause iMovie to fail to render properly.

Brightness/Contrast edit tool messes up my clips.HELP!

When I try to apply brightness/contrast to my iMovie 6.0.3 video clips (because so many of them end up much darker on iMovie than on my camcorder), it helps with the brightness, but after the rendering is done, my clip is messed up in 2 ways: 1) the sound is mainly gone, except for a few jerky sounds here and there; 2) visually, the clip is now jerky--like it's both in slow motion and being fast forwarded at the same time, if that makes sense. I've tried again and again, looked for advice all over the internet, to no avail, and wonder if it's just a glitch in my software and if so, what to do about it? (I did download an update on 6.0 from the Apple site, but it didn't help). Thanks!!

Hi Z
As Catspaw writes.
The Brightness & Contrast tool in iM6 should work - a new account is a smart way to test
where the problem originate.
This tool in iMovie HD 6 - is crude and hard to use/get a good result with.
In iMovie'08 - this is one of the few things that is a real improvment but the loss
of so much other tools results in a useless situation (as Catspaw - I don't nearly use it)
Solution: FinalCut Express 4
• Superb tools to correct brigtness, contrast and colors
• So much more
Cons
• COST - It's not free but price is reduced with 30% after introduction of iMovie'08
• Some new learning. Mainly in starting up (setting up scratch discs & Capturing process)
Some says steap learning curve - there is a step but mainly there are so much new
tools so it's really to learn as You progress with Your movie.

Strange Artifacts with Brightness/Contrast Filter

I've applied the brightness/contrast filter to several stills and then on the last 6 frames, I pump the brightness to 100 to create a flash transition. However, on several of these, I'm getting very strange black artifacts after rendering. They appear on the edges of the frame.
They're not there before rendering, so it's not because that's what the image is supposed to look like at 100 brightness.
Has anyone ever experienced this or have any ideas how to fix it?
Thanks!
Cameron

Interesting development. I got a different transition from Eureka! plugins that's basically the same as the Buena one except it doesn't crash my system. Rendered it, and lo and behold! Same problem. The same kind of artifacts show up on the edges. The problem with cropping it is that then I just have to re-render and the artifacts come up again.
Any ideas?
Thanks!
Cameron

Are there brightness/contrast controls in Flash Player?

Dear Anyone.
I use Flash Player to watch streaming content on a bunch of websites. It's great when the video's been well made but on some of the websites it's VERY dark.
Are there TV-style brightness/contrast controls anywhere within any of the Flash Player interfaces, so I can brighten the picture up a bit? Or is there any other way of doing it - the monitor controls seem to brighten the area AROUND the picture, off the screen, not the streaming picture itself.
Yours hopefully
ulrichburke

As was explained to me, the latest version of Flash Player, with Protected Mode disabled, is the same as version "10.3.whatever," the recommended work-around, in terms of basic security updates.

To the extent possible, we maintain Flash Player 10.3 with critical security fixes in Flash Player 11.4. There is a functional difference, in that new features are not present.
My concern with recommending people disable ProtectedMode via mms.cfg, is that that preference will persist forever and it's extremely unlikely that the average persons is going to remember to undo that preference at some point in the future. We see sandboxing as a critical component of effectively mitigating an ever-evolving class of sophisticated security threats. We're mostly ahead of the threat curve at the moment with sandboxing, but attackers will ultimately adapt and up the ante at some point. If that day comes and a large population of users has sandboxing disabled, that would be an unfortunate outcome, and something we'd like to avoid. To that end, we've recommended Flash Player 10.3, because it is maintained (but will eventually be deprecated) from a security standpoint, and because it prevents that persistent preference from being set. "
The important thing is to remember to re-enable Protected Mode by deleting "ProtectedMode=0" from the mms.cfg file after installing the latest version of Flash Player. (It can always be added again, as I have done, when the newest version continues to cause problems.)

Brightness/contrast controls have stopped responding

Brightness/contrast controls have stopped responding in IPHOTO

Is there a question? If there is, please bear in mind: before anyone can help, they need information to work with. Basic stuff:
- What version of iPhoto.
- What version of the Operating System.
- Details. What were you doing when the problem arose?
- Did it ever work properly?
- Are there error messages?
- What steps have you tried already to solve the issue.
Anything else you can think of that might allow someone else to understand your issue.
With this kind of information somebody can develop a starting point for troubleshooting the issue.
Posts that consist of "iPhoto doesn't work. Help" or "iPhoto won't print" or "Suddenly I have no photos!!!!!!!!!!" mean that any helper is simply guessing. With information, s/he may be able to get your issue resolved sooner.

Colored frames when adjusting brightness/contrast

Hello kind people. I am trying to adjust brightness/contrast on a short clip in my video, and I keep getting some colored frames that play when I replay the clip. I can stop at the colored clips, some are blue, and some are magenta. Anyone have an answer? I have rendered the clips, but I can't figure it out, and have never had this problem.
Thanks,
Mike.
Final Cut Pro 6.0.6

I reset the codec to Pro. All the footage I shot myself with the same camera setting. Also, I am only editing this one short clip, so it's not mixing with anything else I don't think.
I figured out a go around from my problem. Instead of going to Effects, Video Filters, Quicktime, Brightness/Contrast, I am now doing Effects, Video Filters, Image Control, Brightness. It seems to automatically take care of the contrast to make it look nice.

Greyed Out Brightness/Contrast onThinkvision

I have a Lenovo LCD monitor connected to my E520 laptop. I decided against my better judgement to adjust the colour settings today and after setting the brightness up to 100% I no longer have access to the brightness control on my monitor. I've tried restarting, but the brightness/contrast button will not respond. Can anyone help?

Some additional info: the brightness button on the monitor no longer works. I can access the settings by double-clicking the screens enter button, but in that menu brightness settings are greyed out. The computer/Windows is not remembering my calibration settings. I adjusted the gamma and colours to compensate, but it forgets after a few cold starts. Several reinstalls of the drivers doesn't help, trying to update the drivers doesn't help. The brightness adjusts on my laptop, but not on the external monitor. The monitor is an L197 Wide, laptop an E520, Windows 7 sp1, all updates and patches applied. I also tried creating a new user account and switching the graphics, no luck there either.

Set default Settings for Brightness/Contrast Slider

I am in the throes of editing several hundred pictures. My camera has a standard tendency toward too bright and not enough contrast. While editing about a hundred pictures in Photoshop Elements 3.0 last night, the brightness/Contrast and Shadow highlight slider suddenly retained the last setting - which GREATLY enhanced my editing efficiency! Alas, today it is back to normal - the Brightness/Contrast slider default is 0 for it's associated sliders and the Shadow Highlight option is again at 50%/0/0 for the three associated sliders.
Is there a way to set a default value for the associated sliders for each of these?
(I had installed Photoshop Elements 5.0 on a trial basis up until yesterday and also have Photoshop Elements 4.0 installed, but it is such a hassle to use, I just gave up on it (and 5.0 has the same issue as 4.0 - no concurrent file browser when editing.))

Can't help you with Shadows/Highlights, but you do have an option with Brightness/Contrast. Instead of going to Enhance>Adjust Lighting>Brightness/Contrast, go to Layer>New Adjustment Layer>Brightness/Contrast instead. Once you've established the parameters you want for Brightness and Contrast, you can open up additional pictures and drag-and-drop the adjustment layer onto each new picture, retaining the settings from the first adjustment. This also allows you to quickly tweak the settings on the succeeding pictures, as adjustment layers can be readjusted ad infinitum.
If only Shadows/Highlights had an adjustment layer option...

I want to change the settings (brightness, contrast, gamma) for my internal cam on Macbook pro. I find having to but a third party software (iglasses, webcam settings) to control basic settings as unnecessary and exploitative. Does anyone have a solution?

I want to change the settings (brightness, contrast, gamma) for my internal cam on Macbook pro. I find having to but a third party software (iglasses, webcam settings) to control basic settings as unnecessary and exploitative. Does anyone have a solution?

It is not about payment of $19.95 (Igalsses) or $7.99(webcam settings). This is a very basic setting that should be available in the system settings. The automatic setting of the internal cam does not work great on low lighting as everyone is aware.
i am just amazed how users take in lying down and suggest solutions such as paying for a 3rd party paid app or improving the lighting in your room.

How do I save an edited movie with brightness, contrast adjustments

I am using Quicktime pro ver 7.6.4(518.35) and I love its editing features especially the rotation and brightness adjustment features. Is it possible to save a move with these edits so they will be view correct with the basic Quicktime player? I have a movie that I edited the contrast and brightness and resave it as its original MOV file. The new contrast and brightness setting show up when I play the video on the same computer that has my Quicktime pro on it. But, when I play it on another computer with the basic Quicktime player the movie reverts to the original Contrast and brightness. Am I doing something wrong? I even tried to export it to another format and lose the video portion of the movie.
I would hope that I could fully edit a movie save it and give it to my family so they can view it like it was edited. Any suggestions?
Thanks.

Ok, after some searching, I found the export filter settings...
However, the exported video appearance does not match that of the source video with similar A/V settings.
Example 1 = Source video (.3g2) with A/V settings, recorded with screen capture software. *http://www.youtube.com/watch?v=ezvE6sUeUb0*
Example 2 = Source video with similar export filter settings (brightness/contrast) *http://www.youtube.com/watch?v=7tQYXWX17zQ*
When the video gets brighter, the brightness dims and when the video gets darker, the brightness increases... contrast settings seemed to be ignored.
All I can say is.. what the HECK?
It's pretty sad when I have to rely on screen capture software to get the desired result! Luckily the source video was taken with a cell phone, so there was no noticeable loss in video quality.

How to Change Brightness, Contrast and Saturation of an image in LabWindows/CVI (Urgent) ?

Hi All
I want to change brightness, contrast and saturation of an image, plz help me how it will possibe in labwindows/cvi
Thanks

CVI does not include native functions to operate such changements on an image.
It may be possible that these functions are included in IMAQ library, but I never used ot so I'm not sure. In any case, this is an additional tool to install and it is not free.
Alternatively, you may need to search for a third party library that offers such functions.
Proud to use LW/CVI from 3.1 on.
