There is this guy called Charley Parker. He has a blog called Lines and Colors where he talks about artsy stuff he likes, be it digital or analog, outrageous or traditional. I guess when one surfs the web to find art as much as he does, trends start to appear. Here is an amazing post about portfolio sites and mistakes artists often make when designing them.
The whole site is a gem but if you are thinking of building a website (even if it’s not a portfolio,) you should start by this post:How Not to Display Your Artwork on the Web
I have to say that I agree with almost everything he says, it’s really a question of common sense but having it black on white and explained is handy. I’m a bit of a web design old school purist too so it’s good to see that I’m not alone with these opinions. That said, enjoy!
