Many photos were rejected for the quality although i was printing the same photos for years in my gallery and they are sharp and clean in a large prints.

Mojito, Moira II and the boat with vessel ID # are all IP violations.

You can’t sell this image commercially without signed property release forms by the boat owners. That’s to protect YOU and Stock customers from any legal action later. 

As a photographer, you should already know this and carry release forms with you when you travel.

i simply do not trust the artificial inteligency you use.

Review criteria

The Stock team evaluates content based:

• Legal standards
• Technical qualities
• Title and keyword accuracy 
• Commercial value
• Aesthetic properties
• Uniqueness, both in relation to other content you’ve submitted and content already in the Stock collection.

Maybe Stock is not a good fit for you. 

Stock is NOT an Art Gallery.  It’s a royalty-free assets service. Your job as a Contributor is to curate content BEFORE you upload to Stock. Nobody can do that for you. 

Submit only your very best work. And never infringe on the property of others. That’s very important. Read your Contributor User Guide below.

Good luck.

There interface between Lightroom Classic and Adobe Stock only allows you to submit images for review. It does not precheck the suitability of those images, nor does it mark them as rejects. You have to do that yourself.

Did you mean to post an example or two? You mentioned the boat, which could potentially be someone’s property if featured in the photo and thus require a property release.
