Description
I recently 'needed' (more like 'really really wanted') to work out a way to remove the white paper background from sketches I'd scanned, making them transparent so I could stick the sketch over any image and have it blend in nicely with it. It's something I've wanted to know how to do for years, and now I know! Wow! Gasp!You can use the same techniques on coloured images as well, using a channel as a mask; anything you paint black on the channel you'll be using to make a selection will remain 100% opaque and untouched. Everything else will be selected with some degree of transparency. Or something like that.

I am not very clear on the Select & Delete and 'Final Adjustments' part. Don't we need another layer to copy the image to? All I see is the ctrl+click on the channel selected all the black areas for me (?!) and when I created a new layer and got rid of the original old one, it pasted an inverted image in it.

For some reason that last step never occurred to me. I'd be left with those annoying gray colors that wouldn't go transparent with no idea of how to get rid of them. Thanks!

Greatness now all I needs is photoshop! I like tutorials like this with pictures cuz I just wouldn't have the want to look through a Manuel to find it and would just get confused anyways.
