Mustafa, my boy, don't be so tragic! You shall NOT leave photography. Put money, heart and soul into it. Decorate the house with the beauty you see around you in Turkey (now don't go givin' me bull that Turkey isn't beautiful: my professor is over there for 6 weeks on leave with his young daughter and will come back with a stunning visual record, albeit a digital one...). Don't get all sweaty and break out in warts because of the cost of a meter. Guess the exposure. You aren't going to be flogged if you get it wrong.
PS: If you do find $500, please PM me. Thanky!
