One way to become a better photographer is to hang out with better photographers.
Below are two comments left on my facebook photo groups last year.
“I am not talented enough for your group, I am only beginning to learn photography”
“I mistakenly checked into your talented group. My skills are not commensurate with the standards of this group”
I can understand that they may feel embarrassed posting their images along side of all the great images that are being posted by the members of the group, but that is how you grow as a photographer, by studying and learning from photographers who are doing it well. You surely won’t get worse by posting there, and you may even get some help. So hang out with better photographers and you will become a better photographer.
