Black/White Adjustment Layer 101 Pt 2

checker boardThis is the second in a ‘beginners’ series of posts regarding one of the most flexible Adjustment Layers available in most post processing applications – The Black/White Adjustment Layer  and we will be working non-destructively, so keeping the effect fully editable

In the last post we used colour sliders to make a better black/white image, in this post the tables are turned – we’ll be using the sliders of the Black/White Adjustment Layer to modify the colours of the image ! So how do we do this ? The key is in the Blend Mode !

Again, to demonstrate how, we will use the Photopea implementation as it is the least complex.

    • Step 1: Open the image of which you want to alter the colour. Create a Black & White Adjustment Layer from the main menu by Layer > New Adjustment Layer >  Black & White or click on the ‘half moon’ shapeselect adjustment layer and select it from the Adjustment Layer drop-down.
    • Step 2: Click on the Layer thumbnail and you’ll see a drop down of the colours and a default value for each.
    • Step 3 : Change the blend mode of the Adjustment Layer to Luminosity.
    • Step 4: You can then adjust the luminosity (and not the saturation) of the colours in the image by moving the sliders left or right – experiment with them and see the results.

As before, we have taken the yellow and green sliders to the max and the remainder we have minimised. Such extreme adjustments are not something you would typically do but it helps demonstrate the results.
