Nasa does have some software that corrects images, it isn`t a mattter of price, it does not do much more than Photoshop can do, but it does it to exact calibrations, so colours come out right and lighting can be corrected for, it`s meant to provide accurate pictures for geologists etc, it isn`t going to get a visible line of text out of a letter in the edge of a blurry webcam image, they send high resolution cameras to Mars for a reason, they want high resolution images, theres nothing in the world will actualy show you real detail where it isn`t, just stick it in photoshop and try edge detect or false colour filters, they often show up stuff you can`t see easily by eye, but you can`t get an image out of 40 blurred pixels, it just doesn`t work like that.
@Sirfire: see attached, same image, sharpen filter in freebie arcsoft photostudio that came with scanner, just does some edge detection and de-blurring by putting larger steps in colour range between pixels, doesn`t actualy add missing detail, just guesses.
if there is one thing I can NOT tolerate, it`s intolerant people.
