Blend by Brightness - Blending Options for Layers in AKVIS MultiBrush

Blend by Brightness

The Layers’ Blending Options are arranged in two groups of parameters: General and Blend by Brightness (advanced).

Blend by Brightness is used to control the visibility of pixels on the active layer (This Layer) and the lower layer (Underlying Layer) based on their brightness. Each scale has two sliders. At the leftmost slider a pixel has a brightness of 0 (black); at the extreme right a brightness of 255.

Those pixels whose brightness falls within the values between the two sliders will be displayed (for the upper layer) and hidden (for the lower layer). Sliders hide pixels without removing them.

If a slider is moved while holding down Ctrl, the slider will be divided into two parts, which can then be moved independently of one another. Divided sliders set the tonal range between visible and invisible pixels, so you can achieve a more subtle effect with a soft color change.

Actions on the active layer (This Layer):

Upper Layer Lower Layer
Upper (This) Layer Lower Layer

Hiding the dark pixels of the active layer Position of the sliders
Active Layer:
Hidden 0-170
Visible 170-255
Moving the left slider hides dark pixels with lower brightness

Hiding the light pixels of the active layer Position of the sliders
Active Layer:
Visible 0-170
Transition 170-238
Hidden 238-255
Moving the right slider hides light pixels with higher brightness

Hiding the lightest and darkest pixels on the active layer Position of the sliders
Active Layer:
Hidden 0-131
Transition 131-170
Visible 170-192
Transition 192-233
Hidden 233-255
Moving the sliders to the middle reveals only pixels
with brightness values within the range between the sliders

 

Actions on the lower layer (Underlying Layer):

Revealing the dark pixels of the lower layer Position of the sliders
Lower Layer:
Visible 0-93
Hidden 93-255
Moving the left slider makes the darker pixels of the lower layer visible on the upper layer
if their brightness is less than the specified value

Revealing the lighter pixels of the lower layer Position of the sliders
Lower Layer:
Hidden 0-91
Transition 91-137
Visible 137-255
Moving the right slider makes the lighter pixels of the lower layer visible on the upper layer,
if their brightness is more than the specified value

Revealing some light and dark pixels of the lower layer Position of the sliders
Lower layer:
Visible 0-8
Transition 8-145
Hidden 145-216
Visible 216-255
Moving the sliders to the center makes pixels from the lower layer visible on the upper layer
whose brightness values fall outside the range marked by the sliders
