I'm sure someone can do a better job of this, but off the top of my head: Use the Magic Wand tool to select the background. This tool selects all pixels of the same color. You may need to adjust the color tolerance a bit to get everything. Use Selection | Feather so the selection isn't quite so hard-edged. Again, you may want to fiddle with the number of pixels. Select | Invert. ...

OK...I need to learn how to do something ASAP. I need to take a portrait, and then change the background color. The paint bucket fill doesn't really do a great job at that. Plus I'd like to add a little texture so it doesn't look like a digital bucket-fill job. So, if I take the portrait with a neutral background (off-white, towards cream/beige), how would I turn around and create a ...

The first thing I would try is to duplicate my background layer and mask out my subject, then use the selective color tool, altering the sliders for shadows/midtones/highlights to taste. Someone else may have a better solution like a certain blending mode or something though. I think with this method if you have blown highlights you will be stuck with 255 whites. http://img33....

Thanks Gus. That was very non-intuitive, but it worked. The background texture/color was the trickiest bit, but I managed to get something passable. I'm the one that did it and I honestly can't tell that Photoshop was used! :-) 1poorguy

Interesting you should say it was non-intuitive, since after years of using photoshop, that was the obvious, no-thought-required approach. * When possible use a layer. In our example, by making the background a separate layer, there's no possibility we're going to harm the foreground when we mess with the background layer. This is much better than masking off the foreground and then ...

This is much better than masking off the foreground and then altering the image. Masking is what seemed intuitive to me, but I have never done that before. And there are two selection tools, one being the magic wand and the other a quick selection. Didn't figure out how to de-select a portion that I didn't want, but it turned out OK. I'll have to save your procedure until it does ...

I'll have to save your procedure until it does become intuitive to me. If you do that, be sure to think about why you are doing each step. Over the years, I've been asked many, many times to demonstrate how to do specific tasks on a computer. Almost always, I don't know how to do the task when I start, but I also know that with enough exploration and experimentation, I'll figure ...

If you do that, be sure to think about why you are doing each step. I have been...ever since you posted it. The one thing I haven't figured out is what the back layer was for. You had had me select/invert/copy. So I had the original in the back, and just the main subject in the foreground. Then insert a layer between them that became the changed color background...what do I need ...

what do I need the original for now? It's there in case you screw up the foreground. As I said, it's a good idea to work on copies of things. That way, it's easy enough to retrieve your original subject if you're unhappy with some or all of it. Once you're satisfied with the final product, you can nuke the original image layer. Would it not have been more straight-forward to ...
