The screening team has been discussing the motive rejection reason over the last month and have decided to give a bit more leeway when it comes to minor obstructions, From now on we will look to accept images that may have a small portion of the landing gear or engine blocked by runway marker, light and airport signs as long as it is not too distracting from the overall image.Previously these types shots were regarded as an avoidable blockage and get rejected for motive but feel that is not always the case.
Below are a few examples of what is now acceptable.

Over the coming months Quality and Acceptance Criteria team will be reviewing more of our rejection reasons and whether any changes can be made, If changes are going to be made the screening team will discuss it and than inform the photographer community of these changes.
