dslr lenses- get to know all about telephoto, prime lenses, wide angle and kit lenses! Which to use for faces, which to use for places, and everything in between. (great info for beginner photographers)
I always direct anyone asking me about my camera (and how to use it) to this site. Its all explained so simply, and taught me how to start using my DSLR. My sister printed it out and keeps it as a reference in her camera bag. Great idea!
