Anyone else have the problem that the picture you are watching suddenly turns from a picture with craters to a picture with hills? This seems to happen for me more and more often, sometimes when I'm in the middle of marking craters and sometimes with my very first view of the picture. It's very annoying! In fact, in the beginning I would stop marking craters on a picture when this happened. But then I started to get these "warnings" that I "only found 35% of the craters and should redo the tutorial..." etc, so now when it happens I just keep marking the picture, but marking hills instead of craters! Which isn't very satisfying or, I suspect, very accurate. Anyone have a good trick for "reorienting the brain" when it decides that a hallow is a hill?

Welcome to CosmoQuest! There is a tutorial on how to invert your screen colours here (http://cosmoquest.org/Moon_Mappers:_FAQ#I_don.27t_see_any_craters.2C_all _I_see_are_hills.).

Hi Danish... welcome! I have the same problem with many of the pictures. Definitely try kmasterdo's link above--it usually helps. However, I've found a few images where no matter what I do with my screen, it still looks like hills to me! Just keep going--do your best with the image and move on to the next. Don't worry about innacuracy... we have some good statistical methods that help us sort that all out. ;)

Hi Danish,

Some people find it helps if they look away or de-focus their eyes for a minute and then look back and refocus. Others, like me, tilt their heads one way or another until the features pop correctly.

If you want to learn more about this phenomenon, there is a blog post about that: Why Does It Look Like That? Illumination & Optical Illusions (http://cosmoquest.org/blog/2012/01/why-does-it-look-like-that-illumination-and-optical-illusions/).

Cheers

DD - I just posted a reply to this thread (http://cosmoquest.org/forum/showthread.php?552-Need-ability-to-rotate-moon-pictures) that is relevant to the discussion.

Ok, that is a very cumbersome process for WinXP. Is there no way to build in a button in the interface to invert the brightness of an image? Or flip/rotate it?

We are discussing this ability (rotation, custom contrast, inverting, brightness, etc.) for the next major release, or next-next. For the moment, inverting your monitor's colors is the only solution.
