quick introduction to the problem.
Say I have an image on which I applied a layer mask and a black and white effect. (With a duplicate of the mask). Like so:
If I change the canvas size (which happens alot vertically when designing for web), the black and white effect and the photo will show on all the new pixels created. (you can see on the mask panel on the right that all new pixels are white on the mask)
My question is, is there a way around this? (a workaround would be to set the default fill of a mask to black when resizing. That way, the effects WOULDN'T be applied by default.Sadly, I haven't found anything of the sort in Photoshop's Preferences)
Am I using masks totally wrong? Maybe there's a better way to apply black and white to pictures in layout, I just haven't found it!
This might not seem like this much of a hassle at this scale, but when you have 15 different pictures on a page with black and white masks on them and you have to make the canvas bigger, it means that you'll have to manually go through 15 different masks to remove the black and white effect that has been applied to the new pixels.
