I feel ashamed to ask as I’ve been using Photoshop for some 10+ Years but because I’ve seen it so much on other files I must be missing a trick and need a lesson on it.
Below you’ll see smart objects, but you’ll also see a full black silhouetted image too, what’s the benefit of this? Is it for easy quick selection? I see this type of black image a lot so it must have some benefit that I’m perhaps missing?
Any advice is appreciated.
My guess would be that it is provided for potential use as a mask (which you could invert as required depending on where you use it)
Yep, that's a finished mask image, so you don't have to make one yourself if you need it. A mask has about a zillion possible uses, including things like putting the object on a different background and so on.
Thanks guys, I don't think I use masks to the best of their full potential - Some research needed
