I've thought about getting a DSLR as well, but don't know much about the basics, such as aperture, f-stops, and/or photoshop and RAW.
Still a lot I don't know, but I know much more than I did 2 years ago when I started taking a few courses on the internet. I also got some good programs to process photos and use them. I am happy with the improvement, but trying to do better.
