Can't take pics? – Manual Exposure - Calculators for your dSLR or mirrorless camera Review

I guess this is just a five-dollar guide. Useful I suppose if you are using another camera, but this does not do what I wanted which was: to take pics with manual exposure. I want my money back! Contacting Amex to dispute.
