Another thing we talked about in my last class was copyright violation. I hadn't ever really thought that my paintings referenced from various photos and paintings I've found online could be considered copyright violations. I knew I wasn't planning to sell any of them, and it seems extreme that anyone would take exception to my painting attempts.
I went back tonight and added links to the majority of my references, and I'm going to get in touch with a couple of the photographers that have their emails available.
From now on I'll try to paint mostly from my own photos, from someone that's given me permission to use their photos, or from unrestricted stock photos. I do get a lot of inspiration and ideas from other watercolor artists, but I won't be directly copying any of their work, apart from the tutorials I complete.
Tonight I also did some research on giclee printers in my area. A giclee is a high quality copy of original artwork. Once I'm ready (if I'm ever ready) to start selling my art I can sell the original for a higher price, and then sell nice copies for a reduced price.
