One of the best things you can do to improve your photography is to deconstruct what makes a good photograph. It’s a bit of a catch-22 when you’re starting out though. Even if you’re able to spot a really great photograph, you may have difficulty describing just what makes it so good.
Unfortunately, there aren’t a lot of great resources that really break down photographs and explain their elements, why they work, why they don’t, and how they could be improved. But, there are textbooks full of critiques and deconstructions about classic and modern art.
This is one of the coolest websites I’ve run across in a while. Some very knowledgeable people have put together some very interesting videos about some very famous works of art. There’s only about 300 videos online at the moment, but they’re seeking donations to expand. There’s a ton of great information in there.
