a friend of mine asked this question and i couldnt get an awesome answer, so i looked online, through blogger. And lo and behold i found this awesome website that explained it all, its relativly new but had all the info i needed. I liked it so much i posted it on digg for everyone to see, so that more novices such as my friend (and even me:P) can find out about how awesome digital photography is. 
Heres a link to the digg page to you guys can be enlightened about digital photography too!: http://digg.com/arts_culture/Digital_Photography_Guide_What_is_Digital_Photography
What do you think of the site?, and how i can improve my photography skills, as well as what camera would you recommend i buy?
