Since 18 April the above contributor has uploaded 25 posts, each containing the maximum of 4 images, all taken with a Canon PowerShot SX 60 HS camera, which appears to have consistently been used in vivid color mode to depict sky phenomena including volcanic sunsets. These photographs all exhibit the characteristic garish colors that can be generated by over-use of the very powerful Super Vivid creative filter in the Canon SX 60 camera. Somewhat surprisingly these posts have attracted an aggregate of 785 Thumbs Up ratings, an average of 31 per post, which is about three times that for all others submitted during the same period!

I have a number of questions:

1. Is it correct practice and fair on the majority of contributors who submit natural unenhanced pictures to Spaceweather, to consistently post artificially enhanced images which divert attention from these and obtain high scores? Is this not a case of photography on steroids which is conferring an unfair advantage?

2. Is it ethical to publish any such images on scientific and natural history websites without clearly stating that colors have been enhanced and/or are not the same as those observed under the circumstances portrayed?

3. Is there not a danger that publication of large numbers of such images, in this manner, can create false bench-marks, which in time become accepted as the norm for the phenomena being portrayed? If so, this distorts scientific record keeping.
