I want to ask why this picture got rejected by adobe?
Maybe the quality is too low?
It was shot with the iPhone SE 2020
It probably got rejected for technical reasons.
It is not sharp anywhere, it has artifacts, and you are right, it is very low quality.
You can try shooting stock with a cell phone, but it will be very difficult, and you will get very few usable images.
If you are serious about shooting stock photos, then invest in a real camera, either a DSLR or mirrorless.
Ok, thank you.
You should probably get an app that allows you to shoot raw on your iPhone. The iPhone has a quite aggressive in-camera processing that creates nice-looking pictures on the phone screen, but when you look at them in detail, you see the many artefacts. You have also that branch at the upper-right side in the picture. You should photoshop that out. The branches on the right side are also disturbing. You can photoshop them, but it's more complicated. They could also get cropped.
Phone pictures get accepted, but they get vetted with the same stringent criteria than pictures from high-quality cameras. Except if you become a high-quality high-volume stock photographer, photographing what is asked for at the moment, your investment, however, in a real camera won't pay back with stock alone.
