Help regarding rejected photographs

Use a tripod and a larger depth of field.

Hi @eduardo_4752 ,

The file is noisy and had a slight camera shake. 

The second image also had signs of shake and also, you might not have set the camera with enough depth thus too much of the image is out of focus.

Too much of the third subject out of focus due to inadequate depth of field.

Best wishes

Hello,

Another point to consider is the colour temperature/white balance. 

This is too yellow!

I guess these were taken with a smartphone camera. When submitting to stock, you have to do some post-processing in photo editing software. (Photoshop/Lightroom...)

Nothing is in sharp focus in the flower image.

The focus in all three is a little too soft. The photos need sharpening.
Photo 1 the black feathers are under exposed and in photo 3 there are some highlights that are overexposed. 

The bird is out of focus. Or perhaps there was some camera shake, as apparent in the tree.

The flower. Again, focusing issues. Do a search for flowers on Adobe Stock and compare yours to the results. There are millions of flower images of higher quality that you are competing with.

The last one (and whatever that animal is called) 🙂 Focusing issues again, lots of noise. What this enlarged and cropped?
