I have a colour photo and what to convert the background to greyscale but having trouble doing this. The current process I have followed is:
Duplicate image
Desaturate duplicate
Add layer mask (white opacity)
I am working on the greyscale image and have tried using the paintbrush and the easer to bring the colour of the background image through but it hasn't worked.
TIA
If you use the brush it has to be applied to the mask (black for transparency), so make sure you click on the mask thumbnail to make it the target "drawable". At the bottom of the screen, it should display "{layer name} mask" instead of just "{layer name}".
