Hello, I'm Santoso. I'm new to Adobe Stock and I've had a lot of rejections on my photos, most of which are due to quality issues. I hope someone can give me some advice so I can improve in the future. I'll attach the rejected photos.
I can't see your images right now due to a glitch with this system.
If you're getting many refusals for quality, examine images closely at 100-300% magnification. Details should be sharp and well-defined. Avail yourself of the tools in Photoshop or Lightroom to check exposure, white balance and other factors that could impact visual & technical quality.
