Hi Greg,
If you want to try out different editing software I do recommend looking at free open source software they can be very similar to the famous ones. One that I know of and recommend are below:
Dark Table - It is similar to Adobe Lightroom for your Raw Editing. Here's the link...
https://www.darktable.org/install/
Gimp - It is very similar to Adobe Photoshop for your Bitmap editing. Not sure if it has AI yet tho. Link...
https://www.gimp.org/I used both of these before paying for adobe package. But now I use lightroom and Photoshop and I can't see myself going back haha.
Hope this will help
George
