    Can you also post the original image- one of the 12000, which contain this car number?

    Oh, I get it now. That is an important test. It looks like if you had made maybe a 1/50 version, it would be indistinguishable from the original. Or if you had used a slightly shorter focal length, the amount of information would not have been reduced. Or if you had used a sensor with only 25-50% of the resolution, there would be no loss of information. Or if you had used the original sensor at a lower resolution setting which eliminates the need for Bayer interpolation, the image would be even better than the original. There is much to learn about maximizing information in gigapans.

    I was trying to make a point that 250G image does provide more information than a 2.5G thumbnail. I created a panorama of 250G pixels from 12,000 images. Since the file is too big, I tried to upload it to Gigapan 4 times and all failed. Instead, I uploaded a 1/100 thumbnail at www.gigapan.org/gigapans/60510/ .

    Alfred, I do not understand what you did here. What is the "1/100 version?"
