Brightness and color loss

I have a 13' macbook Aluminum 2008 . My friend brought a newer Macbook pro and we compare the MacBooks and his lighting was brighter and the color was better. i check my battery cycle count and its over what the limit is. and every now and then my screen flashes off quicky black . Also my battery doesnt last 30 minutes. Can the battery be the problem of my color and light loss

Could be the battery, but have you changed Color LCD in System Prefrences?

Evening Out The Brightness and Color of a Set of Images

So I have a set of images, usually between 500-700, all taken in a 20min period or so. Natural light through a window. It's shot handheld with my Canon rebel with a 18-55mm lens. Due to the slight change in light over the time period, the fact I'm zooming in and out, and moving around the subject, I get a lot of value and color variation. See the images below...
My current process is to manually color correct each image so they match in terms of brightness and color. This gets very tedious of course. Could someone suggest a faster, preferably completely automated way to even out the brightness and colors of a set of images like these in lightroom so they all look pretty similar to each other?
Thanks for any help!

Yup, that's one reason I think I need a color correction after the fact method to handle this situation, obviously taking a shot that's mostly in shadow will look different than one where the character is almost all in complete sunlight.
I guess I'm really having three issues here, first is the blue tint that gets introduced when I zoom in, and then second is the natural lightening and darkening that occurs as I take photos of the subject from different angles, and third is the fact since its sunlight the light does change somewhat over the 20minute period.
Hopefully the first issue can be solved by turning off automatic white balance, and I'm still hoping there may be some automated method for evening out the value difference introduced by the 2nd and third issue. Although even if I can just solve the first issue that would save me a ton of time.
Thanks for the info so far.

3rd party brightness and color options for quicktime?

I have quicktime Pro. Unfortunately, my graphics card on my ibook 12 inch does not support the video options on A/V controls.
I'd like to change the brightness and/or the colors of some of the movies I watch as sometimes they are rather dark or muted.
On the pro version, I can't do this ( why? I don't know. Isn't it PRO?). I know there are other viewers like VLC that can but I don't want to have to use that because I like the clarity of quicktime.
Are there any solutions to this problem? Maybe some third party add on that I can buy?
Thanks very much.

Depends somewhat on the TV you have in mind.
If a new HDTV you may have choice of HDMI (or DVI), component and composite inputs. Of course, some of those inputs may already be committed to cable, DVD, satellite, etc.
If you have a wi-fi network you might even want to look into Apple TV; a friend was very enthused by his when we had breakfast together this morning.

Changing brightness and colors of an image

Here's code for an applet that will create a gradient:
http://www.sitepoint.com/forums/showpost.php?p=1408696&postcount=5
How would you load an image and do this same thing to the image?
Also, how could you add a slider to change the brightness?
Any tips or code samples would be much appreciated.

Here's the code that changes the rgb values. But, it doesn't work in some browsers and earlier versions of jre. Can you fix it so that it works? Also, how would you add to this code to make it change the brightness of an image?

Ideacentre A520 All in One ~ brightness and color settings not saved

the settings I choose with the touchbuttons on my A520 get lost when restarting. I would like to lower the brightness settings perminantly, how is this achieved?

hi qwertydotNL,
Can you try this instead
1. Right click on an empty space on the desktop and launch Nvidia Control Panel
2. On the left side, expand the Display sub menu and select Adjust Desktop color settings
3. Adjust the brightness / contrast accordingly and reboot the machine
If the problem persist, try to:
4. Check if you have the Lenovo Dynamic Brightness System by searching it on the Metro UI, and reconfigure the settings or disable it to run on Startup.

Screen losing brightness and color fading

I have a 4 yr old Powerbook G-4 and the past two weeks have notices the brightness of the screen is fading as well as the images (screen saver). It is beginning to be difficult to see the files I have on my desk top. Will an adjustment help - what might that be? or do I have a much bigger problem?
Thanks,
Captain Krunch

regarding bsteely's comment...
don't use a screensaver???
i have the middle macbook c2d...bought dec. 2006. i guess i have an lcd screen....so you're saying i shouldn't use a screensaver?? i have it set to run for 30 mins or 1 hr then sleep. it's of all my pictures...i really like it.
i was taught to ALWAYS use a screensaver to prevent the screen from burning out.
so what would you suggest as an alternative?
what does anyone else think??

Color Banding and Color Loss during playback

I'm experiencing weird behavior with Premiere Pro CS6.
As you can see in the above images I'm experiencing banding whenever Full resolution is selected for either playback or paused. If 1/2 or lower is selected then the image looks fine (albeit not full resolution). The images are 1/2 resolution in the Source monitor and Full resolution in the Program monitor. The left image shows the same thick banding as in the right image, with the addition of thinner stripes within the thick bands (don't know if they can be seen at this resolution or not).
This behavior is also not consistent. Some clips don't experience this at all. The clips in this example are MXF MPEG2 clips shot on a Canon XF300 however the same has been seen on everything from AVI to MOV and yet not *every* AVI or MOV.
Another oddity that I'm seeing is that when I use the fullscreen command to make the Full Resolution monitor fullscreen, the image inverts itself (upside down and backwards) and becomes black and white (I couldn't get a screengrab of it though).
My initial thought was that it would be a graphic driver error, but I've uninstalled and reinstalled the driver to no effect. I've also tried reinstalling PPro CS6 with the same results. I'm also tried merely cleaning the cache/preferences... also the same result. I'm at a complete loss and was hoping that someone out there had a solution I haven't thought of yet. My colleagues are not experiencing this issue, despite being on the exact same machines (specs below) with the same updated build of CS6.
Alienware M17X R2
Intel i7 2.13GHz

Windows 7 - 64-bit

Jeff! You're amazing! That was exactly the problem. Thank you also Jim for offering your input. Thank you for solving this aggravating problem. It's been bugging me for weeks!

Brightness and Contrast Issue on Calibration

I've started having migraine issues the last few years. On one machine I have, I wanted to create a few different monitor calibration sets, so that I could switch between sets that were for accurate work, and then sets that were lower in brightness and color temp, which would be easier on my head. I'm using 10.5.8 and an external ViewSonic. I just now realized, that the contrast and brightness settings seem to be overridden by the monitor. In other words... Say that you go to calibrate... You start off by manually setting the contrast and brightness, then adjust all the other settings and save the calibration. If you are using that calibration set and manually change the brightness and/or contrast... clicking on any calibration set, will NOT return the brightness and contrast to the settings you had them at, for that saved calibration set. ie: There's basically only one brightness and contrast setting you can have, at any given time, no matter what calibration set you’re running.
This doesn't seem right. Has it always been like this?

Hi Dave, see if this might be of use...
Go to System Preferences > Universal Access and down in the Display: section make sure that the Enhance contrast: slider is all the way to left to Normal, or more to the right for less Contrast.

Can i make the setting and keyboard background black ? , because i have vision problem and the white color is too bright and cause pain and headache for me . thanks

Brightness Filter effecting quality and color.

Hi, Guys.
I could really do with your help.
I shot a scene in low light conditions so the image is fairly grainy anyway (I shot the scene on an Sony PMW EX3).
Some of the shots are a little bright though. I want to darken the image slightly but when I do this, using the brightness filter, it makes the whole image ridiculously grainy (blocky) and it also changes the colors to like a greeny color.
Does anyone know what I mean and does anyone know how I could adjust the brightness without increasing the size of the grain (without losing quality and color).
Cheers guys.
H

Yes Tom, the reverse ... but steady as she goes going in the opposite direction. You might want to explore some possible denoise options too if the grain is really too distracting.
Take a look at Mattias Sandström's Smart Noise Reduction filter which is part of his completely free and completely awesome Too Much Too Soon filter set: http://www.mattias.nu/plugins/
On the commercial side there is the highly recommended Neat Video plugin: http://www.neatvideo.com
Or ReVision Fx's aptly named DE Noise plugin: http://www.revisionfx.com/products/denoise/

why when I select a bright/rich color it wont let me and is instead a very dull version of that color? Why can't I select a color and get exactly what I picked?
WTF!!!!!!!!!!!!!!!!!!!!!!SOMEONE EXPLAIN THIS!!!!!!!!!!!!!!!!!!!!!!!!!

Check your document color mode and the mode of the color picker as well as your color managemnt settings. You can't print certain colors in CMYK and AI is correctly adjusting gamut based on your settings on that assumption. Work in RGB if you need "pure" colors.

Different look in brightness and contrast in Color as in FCP

Hello,
I've got a problem since the last pro applications update. Since then my clips got a different look in brightness and contrast in color as in FCP.
If I send a clip from FCP to color, it looks more dark with higher contrast. If I send it back to FCP you can see the made changes, but the brightness is higher and contast lower again. And I mean a huge differnce between the both programs.
Before, it was like identical. So, in the moment, it is difficult to make exact changes and the worklow is not so efficent anymore.
Has anyone the same problems or an idea to solve the problem?

Patrick Inhofer wrote:
That tech note specifically discusses how FCP's assumption about RGB files forces it to handle their gamma differently than "YUV" based file formats.
Relevant bit:
Final Cut Pro assumes that QuickTime movies for codecs that support the YUV color space (including DV, DVCPRO 50, and the 8- and 10-bit Uncompressed 4:2:2 codecs) are created with a gamma of 2.2. This is generally true of movies captured from both NTSC and PAL sources. When you eventually output the sequence to video, or render it as a QuickTime movie, the gamma of the output is identical to that of the original, unless you've added color correction filters of your own.
*However, during playback on your computer's monitor, Final Cut Pro automatically lowers the gamma of a sequence playing in the Canvas to 1.8 for display purposes. This is to approximate the way it will look when displayed on a broadcast monitor. This onscreen compensation does not change the actual gamma of the clips in your sequence.*
So what's displayed in the Canvas is an approximation of the "correct" gamma and relies on many assumptions about the media that may not be accurate.

I just switched from Aperture to Lightroom and PS CC. My images exported from LR and PS suffer color loss. Where do I begin to correct this problem?

I just switched from Aperture to LR and PS CC. My exported images suffer color loss? How do I correct the issue?
I shoot with a Canon 5d Mark III in Adobe 1998 Color Space. I've been exporting JPEGS for web with Color Space sRGB.

Does your issue have anything to do with switching from Aperture?
In other words, if you take a new photograph with your camera, and import it in Lightroom, then export it, is there still a problem?
Or is the problem somehow tied to transition from Aperture, or photos migrated from Aperture...?
I'm guessing the reason you brought up Aperture is that you did not have export "color loss" issues in Aperture, like you are having in Lightroom, but since you didn't say... (just want to be sure).

Firefox 36 changes colors on EVERYTHING to too bright and saturated.

I have 28, 33 and now 36. All previous versions had the same and more accurate color. But, 36 makes everything too bright and saturated. Every page. Even bookmark icons. Everything.
Something must have changed. Could have changed in 34 or 35 as I skipped those,. but here in 36 is definitely an issue.
Is there a new setting I have missed?
Appreciate your replies. This is hard to view.

Hello Bob, try '''disabling graphics hardware acceleration'''.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
#Open Firefox ''Options'' window as follows, click the menu button [[Image:New Fx Menu]] and select ''Options'' .
#In the Firefox Options window, click the ''Advanced'' tab, then select ''General''.
#In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. '''Uncheck''' this checkbox.
#Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Did this fix your problems? Please report back to us!
Thank you.
