I honestly have only sold one photo and that was on shutterstock. I never made anything on 500px, dreamstine, foap or any of them other sites and apps. It was like my photography was weak and there's was so much more.
All I seen on there was edited photos and not really many natural like I take. I would always get likes but it's like I and follows. Because of this it turned me away from trying to sell my photos, I did not see a reason to keep trying to compete when everyone was so much more than I was.
The contests that were on the site sometimes the photos that wins or submitted has nothing to do with what the contest and it basically felt like they already had people that they wanted to win. Don't get me wrong I know my photos are not the greatest since I don't edit them and mine are natural also uploading my photos to either one of these they mainly fail because it wasn't focused or any other reason that was thrown at me including they didn't have many people selling the photo or just to many like my photos weren't good enough and then they don't want edited ones but people put nothing but edited photos and it was just picking and choosing so I decided to close them all since it wasn't fair and made me feel less.
