Thanks @sls141, you’re processed image certainly looks like what I’m trying to achieve. However, I’m struggling to replicate what you’ve done. I open my cabinet image (layer 1), duplicate the layer (top of the layer list), then add a layer mask to the duplicate. I then drag a gradient across the image in layer 1 (original layer/image). That all seems to go well.
However, I’m not sure what to do when adjusting the colour levels - playing around with it gives spurious results, it’s not particularly intuitive!
Adjusting the colour curves is a little more straight forward, but I’m nowhere near achieving the required look for the image. I can’t seem to get a uniform brightness across the image, as below.
Can you give me some more info on how you achieved the uniformity of brightness in your second image?
Many thanks!
