I want to sell my photos at a festival here in my town. # 1 Do I really need photo shop to water mark my photo. # 2 does water marking legally make my photo copy righted or do I have to file a claim? Lastly since its digital not 35mm film how do I find my original photo... Few tips would be nice bc even though I don't think someone wants to steal my photo and mass produce them lol I want to protect them so how????
