Very basic, yet very insightful - Marc Silber's eBook and did I mention it's free. It's only 11 pages long, but is very well created. I love the typography in it.

He gives a few tips that are common sense, but most of us usually never think of. There are a few shots of his work in the eBook as well.

If you like the book, he has some great shots of his work in his portfolio. Very inspirational. Now if only I could decide on a DSLR and go shoot some stuff around the city.

You can download it for free from his website.
