That weasel looks a lot like a Pine Marten! Did you visit Dan Hartman in Cooke City by any chance whilst you were there? I was in Yellowstone back in January, amazing place. I didn't see any Ospreys though!

With regards to Photoshop, you could try using Photoshop Elements first as it's a toned down version, so a bit cheaper. Just to get yourself familiar with it. Full on photoshop might be a bit daunting if you've not experience of anything like it before
