What Photoshop Do I Need?

I just recently bought a Nikon D3000 and am learning how to do photography on my own.ihaven'tt taken any classes and don't plan on it, but i want to be able to edit my pics like make some color parts stand out and the rest black and white, or certain things. I searched photoshop but i don't want to spend a lot of money on a program i don't understand how to use. If you know what version of photoshop i need then that would be super helpful. Thank you

Added (1). Also, i do not want a website, i would prefer a software program like photoshop.i've tried online versions and i'm not happy with them

Picnik.com thats the best you can probaly get
lunapic.com that also good
fotoflexer.com also very good

try all three and if it doesn't go straigt to a website just type it in on google.cool have fun

Photoshop Elements is under 100.00, and has the majority of the photoshop tools. You can get a free copy of an older version with an Epson 1400 printer. I bought a 1400 for 150.00 from Staples when it was on sale.

Well if you don't want to spend any money on software, download "The Gimp".It's just like photoshop. As a matter of fact you can call the photoshop for artist on a budget.
