EDITING
Your photo(s) appeared to have been processed incorrectly.

Generally, there are two reasons for this rejection.

Incorrect use of certain features of the image processing software.
Deliberate attempts to alter the image, i.e. by digitally removing or adding objects, or by purposely changing certain items in the image. This is considered a serious offence on our site.
Examples of the first reason are incorrect use of grain/noise reduction tools (such as Neatimage). Noise reduction tools should be used with care. Generally speaking images that were taken in daylight, or ISO 100/200 images from a DSLR should not need any noise reduction. Incorrect use of noise reduction will often result in a loss of detail, and a soft or washed out appearance. Another example is incorrect use of the shadow/highlight tool or the dodge/burn tools. This will often result in light or dark halos around the areas you tried to lighten or darken.
The second reason is more serious. Airliners.Net does not tolerate ANY deliberate alteration of the image for the purpose of the removal of objects from the image, addition of objects to photographs, deliberate blurring of objects (to create an artificial depth of field) or faces, or changing the registration or even entire colour schemes. These type of EDITING rejections can result in a ban from the site.

Editing of images should be limited to rotating to correct horizontals and verticals, cropping, colour and level corrections, and some careful sharpening. Cloning should only be used to remove minor imperfections such as dust marks and scratches.

You can read more about acceptable and unacceptable forms of editing in our Aviation Photography forum at:

If you think you have been able to improve the photos, please re-upload them. Do not forget to include a note to the screeners, detailing what you have done to improve the image. There is a special field available for such notes. Please note that we are still very interested in having these photos in our database, we only ask that you try to improve the quality of the images as much as possible.

A common mistake is the extensive use of grain reduction tools (like Neatimage); see how this tool reduces details along with the grain on the non-acceptable shot / on the other hand the accepted shot with all the necessary details still present - Photo copyright © Thierry Deutsch

In short: any tool used too extensively during post-processing can lead to an editing rejection. Don´t clone out anything else, but dustspots!

Sometimes it may happen that some allowed tools you used create an artifical look that you may not even notice but that screeners might mistake for "bad manipulation"; this again may lead to unwanted consequences. If this happens undeliberately, having a chat with the screeners or presenting your case in the forum may shed some light into the matter for both sides; a nice example of such a constructive discussion can be found here: http://www.airliners.net/discussions/aviation_photography/read.main/284703
