image rejection

This is not the National Geographic, where any image manipulation is prohibited. What you need to submit to stock are correctly edited pictures, with as fewer defects as you can get. Images need to be perfectly clean, and when the deer is in the wrong corner, you have to put it in the right corner. Adobe won't adapt their quality requirements, if you cannot submit for the required quality, you have to stop submitting.

The customers for stock are mostly advertisers and other professionals, who use your pictures to speed up their work, not to have a need to correct your pictures.

How to get clean images from high ISO photos -

Hi @Kleiton R. Alves-Silva ,

My understanding from my training is that grains are not normal, but comes about based on the camera's internal activity such as vibration. The camera is designed to capture objects and space around us as is. Except for dust we do not see grains, which means a perfect photo should not have grains. 

Photo editors are designed to compensate for the inability to avoid grains while shooting. Therefore, we are expected to apply post processing to our photos. You should be using your photo editor to remove grains from your photos.

Here is a list of issues that you should be checking for that you need to zoom in on your files to correct.

You will also benefit from the common reasons for rejections and the tips to get you photos accepted by Adobe.

Review time

I agree, the review time has become a sore point. A restriction policy for the AI floods might mitigate the delay. Unfortunately we cannot do anything about it except to go with the flow. Adobe and the AI contributors need to work that out. It is just unfortunate that it is spilling over on us who do not submit that format.

And by the way, as I reread your message, I think you may have a fundamental misunderstanding of the role of this forum. You write " I suggest you review this image screening policy," but we have no power to do this. The people answering questions in this forum are other contributors, who are willing to share their time to help people learn what is needed to get their photos accepted. The people answering questions have no power to change any policies. You are NOT talking to Adobe. (How do you talk to Adobe about your pictures? You don't. There is no appeal or discussion because it would increase the cost of building the stock photo library).

As far as I know, there is no rejection specific for "graininess". The rejection is "quality issues" which can be almost anything.

Noise does effect the quality of your image. Especially, if blown up to wall canvas size.

Wildlife photography is often done with low light and fast shutter speeds. This increases your ISO which increases your noise. Especially, in shadow areas. Almost all photos need noise reduction.

If you use Lightroom, take advatage of the Details Slider. The new version of Lightroom CC offers AI assisted noise reduction. 

Here an example:

"I work with photos of free-living animals in nature. No manipulation of the animal " This is great! But of no relevance to Adobe Stock. The photos must be technically perfect however they are captured. 

"All images have grain, this is natural."

Some have excessive grain. Some indeed have no noticeable grain. Grain was an unavoidable property of film, sure.

" I've recently been receiving information from you about images created with AI. "

Just ignore it. 

"Certainly whoever does this has never worked in an open environment."

No allowance WHATEVER is made for your environment. If you have managed to take the only known picture of an animal that was believed extinct, in a unique and exciting setting, it will be reviewed the same as all other pictures, and rejected if it is out of focus or has other faults.

"I don't work in a studio with a controlled environment." 

This makes the challenge interesting, but you cannot demand special treatment on this account. 

Hello,

Sorry, but free-living animals have nothing to do with grain or in a digital file - noise; it's to do with the camera sensor. The higher ISO, the more noise you get. (It's like with film, the faster the film, the more grain there is, or rather silver halide crystals.) So, the image screening policy is just fine, actually. There is nothing to review!

I would suggest you read about noise in a digital file!
