Balance is how most image editing is done in Aphera. The seven controls below provide the most common adjustments, which work alongside your chosen Look to shape the tonal range of the image. From a traditional darkroom perspective, you can think of the Look as the chosen film, and Balance as the printing process and paper selection.

Balance and Look tools showing exposure, contrast, and other adjustment controls

Each control has a dedicated key to increase and decrease the effect (organized left-to-right on a QWERTY keyboard). The keys work in all modes so keeping your left hand positioned here allows you to change the image wherever you see it.

Control Description
Q A Exposure Photometric, displayed as the real exposure value
W S Temperature Photometric, displayed in Kelvin (e.g. 6500K)
E D Tint Photometric, displayed as a signed value (e.g. 18)
R F Contrast Overall contrast; pivot around middle grey
T G Shadows Lift or compress darker values
Y H Highlights Lift or compress lighter values
U J Saturation Increase or decrease color intensity

Photometric means the control operates on the scene’s light values, so an adjustment behaves like a change at capture-time, not an edit to the finished image.

The Contrast, Shadows, and Highlights controls are the same operations found in the Grading Layer, but are used for Look-agnostic adjustments.

The Saturation control is the same as found in Aphera 2499, providing rich color intensity using the full scene-referred data.

The order of controls/keys follows our principle of broad-to-narrow; in general we recommend to apply changes from left to right.

Keyboard Stepping

Each shortcut steps the value up or down by a fixed amount. Two modifier keys change the step size:

Modifier Effect
(none) Normal step
Shift Large step (3x normal)
Option Small step (1/3 normal)

Resetting Balance

Use Cmd+R to reset all Balance controls to their default values (in all modes except Crop). When the image doesn’t feel right it’s often simpler to reset, then dial in a new balance adjustment.

To reset a single control, right-click (or Control-click) any Balance control to open a context menu with a Reset option, returning that specific control to its default value without affecting other adjustments.
