Here its not possible to take pictures of shopping malls, without permission, due to security questions.
And i should buy an 8mm lens to take picture of people walking. hehe
Im with a 18-55 on a 450D. It gets 29mm with the crop factor.
It means almost 40 pictures (without hdr).
Its almost impossible.
So, lets think.
Youll take the pictures (to have a portfolio).. and will offer them based on wich information?
Theyll ask: "Why are you offering me this? How good will it be to the shopping that justify the investments?"
Thanks again!!!!!!! :)
