Re: [APML] Orion panorama
Thanks to everyone for the comments.
Paul, thank you very very much for pointing out this. It is not an illusion.
It's an artifact that I didn't quite notice. The lower 2/3 of the image was
scanned about a year ago by EPSON 1620 at 1600 dpi. The upper 1/3
was scanned this month by EPSON 4870 at 3200 dpi and down sampled
to 1600 dpi. I know that the 4870 results are sharper than the 1620 ones
but I didn't know it is still so noticeable in a 0.1x image. I will
think about
a way to solve this, hopefully without rescanning all the old frames.
Cheers,
Wei-Hao
