Gamma Control is an application that gives you the possibility to adjust the gamma correction curve of the screen. Use the application to calibrate the screen for new ambiant conditions without having to use the ColorSync Calibration Assistant. You can save your multiple settings in documents and retrieve them when needed. The settings you change are not saved into the current ColorSync profile and are restored when you quit Gamma Control.

What's New

Version 4.0.1:
  • Fixed an issue where some preferences would not work in the English version of the app.
  • Added saving and opening setting files in the menu under the app icon when put in the menu bar.


OS X 10.6.6 or later

I am pleased to say that the Author quickly got onto the problem and fixed it up tout suit. I am now revising my review.

Decided to revisit this app but when requesting a trial code, the authors web site gives an internal server error. Very reluctant to pay $6.99 after this experience

Sorry about that. It's fixed now.

There is a small mismatch in the PHP version installed on my server and my local test machine. The redirect script handling clicks from the application failed once installed on my server. It's the first day of deployment of my web store on michelf.ca, and also the first day I'm allowing trials (previous version was Mac App Store only), and testing this small but important redirection script once installed on the main server was neglected in the grand scheme of things. Thank you for letting me know.

If you don't trust my server anymore, you can also purchase from the Mac App Store.


ThankYou Michel, I just wanted a trial license for a few days to see if it met my requirements. I'll try again.

Link seems to be dead (original author's site is down). Internet Archive to the rescue: http://web.archive.org/web/20121031210333/http://michelf.ca/projects/gamma-control/

You maybe "calibrating" the screen (not really, do you have contorl over the color temp? The contast ratio? The backlight intensity?). And there's on ICC profile to reflect this change on screen which makes this product questionably useful at best.

Very simple, very efficient. It's possible to calibrate several screen connected on the same Mac in a few seconds. Just what I needed. With some apps, the tree cursors move together (even with or without shift), but come back on the desktop and everything become right again.

I have been waiting patiently for a version of the old Adobe Gamma control panel for OS 9 to reappear for OS X. Now it's here, and it's free! I have used it to fine tune my printer-to-screen output, improve DVD viewing and more. An excellent application. Cudos to the developer. Great work!

Easy to use program. Just click the icon, and it toggles itself on and off. Does EXACTLY what it says. Helps out when you want to design for a PC, or when you want to calibrate your screen to printers and such. (Using OS 10.4.3)

solid little app. the great thing about it is when you click off the gamma control, it goes back to where your monitor colors were before you turned on the app. A seemingly simple thing, that has been botched many times in other apps.

Would love it if it had curve and/or hue saturation lightness panel. It supposedly allows you to import photoshop curves, but I haven't been able to figure it out.
