I have just started the basic city and guilds photography course and am so confused about what camera to buy as i am doing it from home, i need one that has manual aperture and shutter speeds. I want one that is going to be good for a while i just dont know which one, what are the key points for a proffesional camera, think it would have to be film as i later want to do the black and white course which involves developing your own. Would appreciate all advice as im so confused about everything. thanks Lauren
