White Balance adjustment

The adjustment lets you control white balance using:

Apply this adjustment via the Adjustments panel using the following settings:

Balance—controls the emphasis of the adjustment. Drag to the left to cool the image, or drag to the right to warm the image.
Tint—tints the image either towards magenta or green. This is useful for removing color casts, especially if the image was taken under artificial lighting (e.g., tungsten or fluorescent).
Opacity—sets the level of visibility of the adjustment.
Merge—merges the current adjustment layer with the layer immediately below it in the layer order.
Reset—reverts all adjustment settings to default.
Delete—closes the settings and deletes the adjustment layer, removing the adjustment.
Add Preset—adds the current adjustment settings as a preset for use with later images and projects.
