Why are all my pictures being rejected because of quality issues?

Stock has a very high standards bar.

Other microstock services have different standards & customers. 

It wouldn’t hurt to try your luck with other services. 

Good luck.

Don’t waste energy on things you have no control over. Instead, focus on your OWN WORK and ways to improve content for commercial success. 

Unfortunately, trees, bricks, flowers and sunsets have generous representation already. The likelihood of getting accepted and making sales later is quite low due to so much competing inventory.

To succeed at Stock photography: 

• Look for less well-represented subjects that customers can use in commercial projects.  
• Think outside the box. Experiment with new ways of looking at old things.
• Express a message or emotion in a visually interesting way.
• Create pictures that tell a story and invite viewers into the world you’ve captured with your camera lens. 

Hope that helps.

Hey ​@natureloving_naturalist 

slugs on Adobe Stock 365000+ images
Brick Wall  13+ million images
Tree bark  943 000 images
 
2nd… consider your audience who is your target audience? What problem or solution is/are your images solving? When would your image be used?

3rd Adobe has raised the bar considerably for Stock Photography.
