Description

Gamma Control is used by designers, photographers, and filmmakers to improve color reliability or adjust screens so they fit within various lighting conditions in pictures or videos. It can also be used when playing games or viewing videos to reveal details normally too subtle to be seen.

UNVEIL SECRETS LURKING IN SHADOWS

The middle point adjusts the tint for grays and can lighten or darken intermediate colors. The setting applies to the whole screen in real-time so you don’t need to take a screenshot and open an image editor. Just start your video or play your game and enjoy the lack of darkness.

AVOID FLICKER WITH LED-BACKLIGHT PANELS

Many LCD panels today adjust the brightness of their backlight using PWM (pulse width modulation), switching it on and off quickly like a strobe. Generally invisible to the naked eye, this will often result in horizontal or vertical lines when captured on camera.

To avoid this, maintain the screen at its maximum brightness and instead reduce the luminance of the white point using Gamma Control.

BLENDING IN THE DECOR

Gamma Control lets you balance the screen’s colors with the ambiant light. If the screen looks too blueish or is otherwise clashing with its surroundings, adjust the white point to better match the the environnement and lighting.

If you are filming with a camera and the mid-range colors appear too bright (washed out) or too dark, adjust the middle point until the camera sees things the way you want.

CALIBRATION PATTERNS

Gamma Control has calibration patterns integrated in its control window. Click on them to enlarge in a separate resizable window you can look at from a few feet away.

CONFIGURE FROM A DISTANCE

Use Gamma Board to you can change the settings remotely from an iPhone or iPad on the same network. Check Allow remote configuration in the preferences and this Mac is ready for Gamma Board.

Important: remote configuration can only be active for one Mac at a time on the local network with the Mac App Store version of Gamma Control.

MORE POSSIBILITIES

• Toggle between dark mode and light mode following your preferences.
• Move the Gamma Control icon to the menu bar to save space in the dock.
• Calibrate each screen by moving the control window from one to another.
• Make the control window appear under your mouse pointer at anytime with a key combo.
• Hold Shift while dragging the red, green, or blue slider to move all three simultaneously.
• Use a global keyboard shortcut to activate and deactivate the settings.
• Use arrow keys to increase or decrease values in text fields.
• Save your settings to transfer them to another Mac.
• Touch Bar support for the newest MacBook Pros.

REQUIREMENTS

Dark mode requires OS X 10.10 Yosemite or later.
Remote configuration requires Gamma Board, sold separately.

What’s New

Version 6.2.1

• Fixing an issue with some video adapter misreporting its serial number. (Gamma Control uses the serial number to identify screens when possible.)
• Reseting gamma curve more proactively on quit, instead of counting on macOS to do it for us. This does not change the behavior of the app but resolves a somewhat nebulous issue with video capture and/or playback with certain applications on particular hardware configurations.

Amazing, Simple, Fixes Mac Default Screen Color

I work in video production and need my screen to actually be white balanced so I can see what I'm doing when color correcting footage. For some reason, the new Mac Book Pro's (2018) have a green tint to the screen and there was no way to fix it with default Mac color settings. So I did some research and found this app and used it to correctly white balance the screen and remove the green tint. Problem solved. 10/10 would recommend for anyone who wants their screen to look correct.

Good but I miss DarkAdapted

Response to developer's tips: Changing review to 5 stars, though I knew all of this already about Gamma Control. Would still love to be able to hold down two (or even three) modifiers and begin scrolling and gamma starts being adjusted right away - no other hotkeys needed. The very first scroll command might make the page of whatever app I'm in move a tiny bit, but then the Gamma Control window would appear under the cursor and the rest of the scrolling would adjust gamma (as it does now). The window would disappear on its own briefly after I stop adjusting gamma. This is how DarkAdapted works. I recommend trying that app out on a machine with Mojave or earlier and replicating its functionality.

Original review: I like this app, but I used to use DarkAdapted, which Catalina will render useless because the developer is no longer updating it. With DarkAdapted, I was able to adjust the brightness of my display with my scroll wheel by simply holding down the modifier keys of my choice (I chose Option and Command) and scrolling up and down. DarkAdapted would intercept the scrolling and adjust the brightness either up or down. Gamma Control can do similar, but it doesn't start adjusting right away, and you have to press a keyboard shortcut to make the brightness slider appear. I'm using Keyboard Maestro to at least get the brightness slider to appear by pressing Command-Option-Mouse Button 3, but I would love to be able to adjust brightness right away by scrolling up or down without having to make the window appear first.

Tip #1: when the mouse is over a slider, you can scroll up or down to move the knob.
Tip #2: when you hit the key combo, the window is positioned so the brightness slider is exactly under your mouse pointer.
Tip #3: if you hit and hold the hot key, the window will disappear when you release it.
By combining all these tips, you should be able to hit the key combo, scroll up and down, and release. Send me an email if you have questions or suggestions.
