I've uploaded many images recently, most have nee rejected for "Quality Issues". Can someone please help me understand what exactly I need to improve/change? Please see example image. CC welcome.
You're competing with content captured by 20-40 megapixel cameras. Small phone cameras can't produce the same level of visual quality.
If you're serious about being a Stock photographer, start saving for better equipment (new/used DSLR or Mirrorless camera, a couple of lenses & tripod).
Consider enrolling in some Photography courses to learn about camera settings, lighting, composition and post-editing in Photoshop or Lightroom. Photography is like learning to play a musical instrument— a commitment to study & practice, practice, practice.
Hmm, thanks. I shot this with a nikon Z30 in RAW. I'm not sure why it's looking like a shot from a phone. I exported it from LRC as a JPEG with quality=100, sRGB, 300 DPI. Should I use another format? I'm not understanding why I'm having this issue.
This appears to be a low resolution cell phone snapshot due to the lack of sharp detail. It's underexposed, and would require a model release due to the recognizable person in the frame.
