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.

CREATE A COLOR PROFILE

You can export Gamma Control settings in a color profile. This profile can be attached to a screen in System Preferences and the settings will stick even when Gamma Control is not open.

You’ll need to export a new profile and select it again in System Preferences if you want to change the settings.

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.

Excellent, low-cost manual calibration tool

So I used this while waiting for my calibrator to come through the mail and must say I'm quite impressed : it's easy to use and provide all you need to adjust the gamma yourself. The WPL function is especially handy. I printed from manually calibrated screens before, and while this isn't a replacement for a "proper" hardware calibration, I think it can get very close. First off, I reduced the WPL to 0.77, then got the red channel down to 0.96. I increased middle green to 1.06 and black green to 0.02; Mac OS Big Sur is really on the magenta side. Also, the grey balance is amazing to keep contrast intact for true blacks on an IPS display, while avoiding crushing the dynamic range; I found the best compromise to be 1.11 on this value. Not that my MBP is calibrated this way, I find that the colors are much better, with truer blacks and whites but less saturation, a good sign that the calibration is good; even my old TV is outputting a better image now and I'm able to tell exactly which side it leans in. My LG 4K IPS display is now giving me virtually the exact same as my built-in retina panel. I followed the advice to keep brightness at 100% and reduce the WPL, and it's perfect! No more pulse modulation issues. For 1/10th of the cost of the cheapest calibration hardware you can get, this is a no-brainer! It also allow you to quickly correct uncalibrated screens on the go when you can't run a full calibration process. Fantastic.

👏 A MUST TO REDUCE WPL

SIMPLE AND DOES THE JOB.

SAVE YOUR EYES BY CUTTING THE WHITE POINT LUMINANCE.
