Curious on what technical aspect caused this photos to be rejected? Thanks in advance :)

I agree with all the above comments, but just want to add that photographing street scenes for possible use for stock photography is a waste of time. The effort to edit out the many, many license plates, logos, streets scenes, etc. cannot by justified by the very small royalty payment that you "might" receive.

9310:

The histogram does not show underexposure, but the white spots of the direct flash are disturbing and introducing chromatic aberration.

In addition, the picture is not in focus and is noisy, respective the noise reduction is very visible. The framing is not the best. The iPhone does not produce good pictures at ISO800. Food pictures need preparation and you rarely get good results with this "on the fly".

9059: Contains artefacts, due to the in-camera processing of a small sensor camera:

The printery look is present over the whole picture. I just wanted to look at the logos on these containers…because logos are also a no-go! Here you don't need to edit those out, the picture won't pass anyway. In addition, the horizon is not level (my teacher's always said: the ocean is running out) and the framing is bad. The complete set-up looks like a typical snapshot. If you want doing stock photography (or product photography), you need to arrange your objects, take the correct perspective and get your shot.

9307: Forget taking night pictures with your iPhone for inclusion to stock. That never works, as the iPhone takes good quality pictures only under best light situations. So, the picture is noisy and has the typical painterly look and has all kinds of artefacts. And in addition, it is not level.

Despite your (amateurish) efforts to edit out the licence plates, you have left out some plates. When you edit out something, it needs to look naturally. In addition, you have "forgotten" to edit out the car logos. Here only two examples:

If this picture had been so clear as needed, you would also need model releases from numerous individuals on the road:

I'm sorry to say, but none of your three pictures here is anyway near to get accepted in any decent stock image database. Moderators had an easy job to refuse those. You need to look at your pictures at 100%+200%, and if you see artefacts, noise or other defects, the picture is not fit for stock. If it's not sharp, it's not fit for stock. If you have logos, you need to edit them out. When having many logos, like with your road scene, simply forget it. It's a lot of work to edit them out correctly.

For me, in the case of the first 2 photos, the main subject is not presented in full, meaning it's "cut-off" here and there - the vegetables go out of the frame and some part of the pot lid is missing. Maybe this was not the main reason for the rejection, but I have a "subconscious" feeling of incompleteness. In the case of the tea pot, I'd blur the background because it's distracting.

Through out your photos are overexposed highlights. The white spots where all details are lost.

Hi @HugoTrix

The first file is underexpose and noisy.

The second photo has chromatic noise and evidence of camera shake. I also believe the composition would be better with glass remove and a less crowded background.

The third file is also noisy.

Zoom in at between 100 and 200% to see the issues of your file.

Best wishes
