So essentially, what should I buy first for like under 50 dollars? Maybe some filters?
I'm from the "
UV filters for lens protection are a huge waste of money", school. That's what lens caps and hoods provide the protective function with minimal added problems.
You'd be hard pressed to find a
good CPL filter for $50.00 let alone a selection of ND and GND filters. Look at B+W brand filters. Hoya makes some good one but they also make some junk so be careful. Don't cheap out on your gear, because it will cost you in decreased image quality and crap resale value after spending the money to upgrade later.
Like Bigtwinky suggested photographic knowledge is the first goal, equipment is secondary. To paraphrase an old saying; it's not the camera and equipment that counts, it's the skill and vision of the photographer that counts.
Books for a basic photographic library, if you don't already have them:
Understanding Exposure,
Learning To See Creatively,
and
Beyond Portraiture by Bryan Peterson.
Light: Science and Magic. An Introduction To Photographic Lighting by Hunter, Biver, and Faqua.
For learning the elements of photographic composition see:
The Photographers Eye by Michael Freeman
Then when you get image editing software you need a book or 2 on how to use it. Scott Kelby is the #1 Adobe Photoshop/Elements author though I also like Phillip Andrews, Tim Grey, and Martin Evening.
