digital vs optical
Thanks for the picture.. this is exactly the test I was looking for..
I took your picture 2, cropped a small area, zoomed 640%, applied Unsharp Mask, and unzoomed it by 400% .. got finally the 170% that the B-300 provide, right ?
The digitally processed image is at: http://home.earthlink.net ...roppedzoomedunzooomed.jpg
Compare it with your picture1... ignoring the difference in exposure (contrast, colors).
. the problem is one of the building, that has jaggy line. This is where the optic zoom has a definitive advantage. Why the jaggy lines ? Your original picture2 gives the clue: smaller pixel sizes would have been recommended for a better anti-aliasing.
. Some of the small objects (small details) such as people on the beach are less clear in the retouched picture2 than they are on the original.
But overall, the image isn't as bad as one would have expected from a digital zoom. I will try different approaches later today to try to get a better result, without using only IrfanView and PS6.
Have a good day, talk to you later,
