Starting some time ago, probably 3 months, the level of refused photos that I have submitted became unbelievable. Really, I do not understand the reasons and neither the refused reason is showed. Same photos I have accepted by other stock pictures. Also, this is a paradox, why so much rejections while Adobe is posting on the media advertisement asking people to upload their old pictures? Samples of rejected photos.
Both photos are underexposed and not sharp.
I agree with @Ralph Lear , these are underexposed and lack sharpness. Make sure to zoom in on the details, between 100%-200% to spot the technical flaws.
Shooting at f1.8 and 50mm and that close to a subject would have a pretty shallow depth of field, I'm not surprised there is so little in focus.
Hope that helps!
Other microstock agencies have different standards for acceptance.
If you're having a lot of rejections, check your equipment.
That said, Adobe has millions & millions of perfect flowers to choose from. Sales potential is low in such a fiercely competitive keyword category.
The hibiscus is underexposed and too much is out of focus. There are also detail lost. Also there was a shake.
The second flowers also is underexposed and too much is out of focus. It seem to have a white balance issue also.
