Hello everybody, i'm relatively new to the micro stock i'm contributor on all the Big 4, all Middle Tier and others less important, i started in july and only now i have a doubt about dimension.
I use my D800 that give me a very big file 7360x4912. I always thought that the most big i can the most better, so i always uploaded the original dimension (less some crops for adjusting if needed) and really take lot of time to upload even if i do in the night by ftp).
Maybe too much big? Which is the better dimension? What dimension usually you use?

Thanks Maximilian
