Hi all, Just noticed this forum after reading a thread about upgrading from a D40 to a D90 and it seems there are quite a few experienced photographers on here and I could use some help. I have read Brian Petersons book "understanding exposure" and have been using my D40 on manual modes ever since. I have been taking some photo's that to me look quite good but I am unsure how well they will stand up to the more experienced eye and would appreciate some constructive criticism. Here's a few pictures I took of my dog the other day at the beach: These were all taken with D40 and kit lens. I do have the 50mm f1.8 but I haven't been using that a great deal lately as Im getting sick of missed shots with manually focusing (one reason why I have been considering the D90).
