I keep a very simple set of software that I use for photography. Really simple. Editing isn't really my thing. I like to share the images as I see them. I don't like to fake compositions or content. And bluntly, I'm not very good at the complicated editing.
Adobe Photoshop Elements
Elements provides an incredible breadth of capability at a relatively low cost.
I have never run into any limitations of the software (again, I'm NOT a great editor...), and have been able to get through hundreds of "difficult" photos. Of course, the two on this page are the ones that have required significant effort - but I learned a lot in doing them, and I was (and still am) very proud of the results.
As a note, I always purchase the available version instead of the monthly plans. Usually, you pay off the difference in just a handful of months (at the time I'm writing this, it's between six and seven months of subscription pricing). On the other hand, it means that you don't always get the latest features.
Adobe Lightroom
I have heard great things about Lightroom, but have not actually used it myself. Please leave a comment and I'd love to hear about your experiences with it!
