1.This is a very well covered subject in our data base or the subject of your image is too specific. We are looking for images that exceed the technical quality and creativity of the images already online. Please take a few minutes to browse through the best selling images online (on this subject) and go deeper, play, have a more creative, more personal approach to it, also keeping in mind the technical quality of the image.
2.Image is not RF stock oriented or its sales potential is too low at this stage. Please note that Stock photography is a commercial type of imagery, so, snapshots are not Stock. There are several vital requirements that an image must meet in order to be stock oriented. An image must serve a purpose, must have a concept, must have a good technical execution in terms of composition, exposure, light setting, optical performance. Creativity is a keyword for a successful stock image, as well. It is also very important to understand that Art and Stock are two fundamentally different categories of imagery, that only meet when an artwork can adapt to a wide range of commercial usage
3.The image contains elements that might be protected by copyright/trademark (logos, brands, specific buildings etc.) or could raise usage problems, therefore it doesn't qualify as a RF stock image. Analyze the photo closely and remove these elements if possible or try to obtain a property release. Read more: https://www.dreamstime.com/thread_148
4.The image includes recognizable humans. It cannot be accepted without a model release signed by your subject(s). Also, take note that, if the main subject of the image is a person, a model release is required even if the face is not fully visible. If the people within your photo are not the main subject but their faces are visible, then you also need a MR for each person whose face is visible. You can download the model release document from the following address: https://www.dreamstime.com/model_release.pdf
