Why have my images come back as "Quality Issues"? Just want to see what Adobe is looking for and what to avoid.

I understand frustration in rejections we don’t understand. These photos are nice, you could have done this or that, but in essence I think they lack commercial value. The camel photo in particular is GREAT, and spot marketable. 

Of my 3100+ photos and videos, about 50 are beautiful landscapes, time exposure shot with a tripod, neutral density gradual filters, and maybe sold no more than 3 in 18 months. Understand that working for Adobe as a moderator reviewing submissions is not an easy job. 1000’s of photos daily under strict guidelines, (betting over half are bad ) and creates mental fatigue, that often make good photos get rejected from a pile.  

I like what you are seeing and daring to do with the camera. Trust when I say that is way more valuable than having the photos accepted at this point. I’d like to know more details on your photos. If you’d like send me a private message and I’ll send you my email so you can send me the raw and the final edition of the camel photo you sent.  I will give you some helpful tips on how to go forward improving your photography and stock experience.

Cheers!

The gondola. It should be composed so that it is to the left or right, depending on the direction it’s going, to give a sense of movement rather than looking stuck in the middle. The logo needs to be removed. White balance and exposure issues.

On several photos the shadow exposure is wrong. Landscape photos should be in landscape mode. Eifel tower at night is IP protected and requires a property release. On most photos the composition needs some work. Light glares need to be removed. Identifiable persons need a model release. Photos need sharpening. The first photo has a lens dirt spot and unwanted branches on the right side.

Composed to the Rule of Thirds. Exposure corrected and photo sharpened.

The woods on the left are crushed into solid black.
Images with blown-out highlights or crushed blacks are subject to rejection.

Tower
A matter of composition.
You shoot using a composition that makes it easy for the photo buyer to use the image.

There is text in the image, so please remove it using Photoshop.
A model release is required if a person's face is visible.

There are black areas at the top and bottom, making it difficult to use as stock photography.
People are visible in the image, so a model release is required.
