I still need this. No recommendations? I am trying to picture our house painted greige with a new wood feature on the front. Do I need photoshop?

You don't need Photoshop ... go to www.gimp.org and download the GIMP. The GIMP: the General Image Manipulation Program

It's free and does anything useful that Photoshop does. I've used it since it was first released in 1995, and in head-to-head challenges, I can edit a photo with it that can't be told from the one done with $$$$ Photoshop.

Many tutorials available for it, too.

I'm going to slightly disagree with lazy about the GIMP. It's free, but it still looks and functions like software designed by a committee. If you have Pshop experience, yeah, you can learn it fairly easily, but the documentation is absolutely terrible for people with no photo editing experience. She's right that it's very capable, though. But it's free, so you might as well try it.

If you have a mac, try the GIMP derivative Seashore. It doesn't do exactly everything GIMP does, but it's easier and also free.

I used to write books about Pshop, more specifically Pshop Elements, but these days I mostly use only Affinity Photo. If you have windows I don't know how the windows version is, since I only use it on the mac side. They have superb documentation on their site, alas for me (no book opportunity there).

If you really want to grapple with PS or PSE, the free trials are here:

But these days I'd say that PS is easier to use than PSE, unfortunately. PSE is all junked up with useless clutter now and many of the tools don't work as well as they do in full PShop.
