Mesas / Plateaus on the Moon again (APOD 9 Feb 2007)

Post by XRDGUY » Fri Feb 09, 2007 8:42 pm

Once again, a lunar image in which the craters appear to be raised plateaus. This optical delusion is easily preventable by remembering that humans are conditioned to expect illumination from above = the top of an image. Or, as I read somewhere that WWII photointerpreters were taught, remember "SSS" for "Shadows Stab Stomach" and re-orient the picture to conform. Turning a book or magazine picture by 90 or 180 degrees is also frequently useful.
So would the posters of APOD images please try to remember to rotate the images as needed?
Don't die wondering if you could have.

Alan Friedman has the image on his web site already at a different orientation.
