>>3000453>selling onlinehard to do, pretty much every photo site ever is doing this and the market is pretty hilariously flooded. You will competing on a world market. If you're a social media whore this might be a decent route.
>arts festivalI'm assuming you mean one of those minor weekend craft and arts fairs. These are viable, there's a few people here that do it quite well.
http://www.alexburkephoto.com/ this guy does it and does it well. His work is solid, printed and presented excellently, and his booth excellent. This route is a lot of work but can be a living. There's a definite price cap for this route.
>galleryIf you can get into the right market and gallery you can do hilariously well. More likely you'll be in a hard market or straight up awful market without a good enough gallery (or work) to make this worth your time. One huge advantage of this route is if you get in a good gallery you don't not have to personally sell work or build a client base. You're relying on the gallery to do this and this is why they take a percentage. Galleries can take anywhere from 30-70% these days with 40% being the magic number. Be wary of galleries taking more or less. Also avoid galleries that have a pay to play model. I've been approached by a few of those but everything I've read and other artists I've talked to have convinced me away. They generally still take a percent and so it just isn't worth it. If you gallery route don't expect to make money for a long time. You're there because showing work is important to you, not making money.
>>3002107>metal printsseconding this for art festivals. You should still have some prints out but metal prints these work well. They also work well at low end galleries and those awful 30 artist group shows. Metal prints are also very look work and effort not only for the buyer but you as well.
