We wish to advise all our members of a new rule in the Terms of Service, regarding HDR (High Dynamic Range) photos. You will find it as point #9 in the Photographs section at http://www.trekearth.com/terms.php
Here is the new rule:
9. HDR (High Dynamic Range) photographs - HDR images should have a photo-realistic effect with the sole purpose of raising the level of detail in a sky or shadowed area to the point where it keeps the appearance of a normal photo. HDR images which have a surrealistic effect or no longer look like photos will be removed at the discretion of the Moderators. This applies to HDR photos produced by software or by the camera itself.
