Galileo Imagery, I couldn't find a topic not specific to one moon.... Options

[tedstryk]

Here is a combination of all of Galileo's global color views of the Galileans. I have left out the large Europa mosaic because much of its color data is pulled from other orbits. I have also left out colorized views. Due to inconsistent filter selection, there some variation between images. I posted the Europa set in another thread, but I figured I would add the views of Ganymede and Callisto.

My non technical argument would be that we use monitors to view every day photographs and video (of ordinary subjects) and the images look correct and "as it should be".
So if we replicate the same processing that our normal digital cameras do and apply it to raw image data, the results should in practice be the same as is if the images were originally taken with that camera.
As for the Phoenix image posted, I'm forced to say that the right version does look like a normal digital photo taken on Earth. Therefore, it's as real as any photo viewed on a PC screen. But this is just my opinion of course.


But more technically speaking, the left Phoenix image is NOT faithful to image reflexion values unless you forced your monitor to display also with a linear response!
If the monitor is sRGB, it will apply gamma to that image, resulting in a non-linear display. So the right version has the correct linear response.
