Thank you for your response.
I suspect that you have looke on "Nacka Strand (4)", but might be
wrong. There are 3 others in that serie which I suspect show more
shimmerings in water that (4) as no sharpening was applied to the
water in that one.
Also, regarding the saturation, I agree that this last nr 4 was the
greyest of all and therefore increased the it a little bit, how does
it look like now?
Or do you think that the others also suffer of the same flatness?

Hi Mahmood, Please be very careful with increasing saturation of a finished pano, especially if it is only 8 bits in colourdepth! You ll get ugly posterizationMessage 1 of 14 , Sep 2, 2007View SourceHi Mahmood,
Please be very careful with increasing saturation of a finished pano,
especially if it is only 8 bits in colourdepth! You'll get ugly
posterization (did I spell that correctly?) in clear skies and other
relatively featureless areas if you overdo it just the slightest bit!
It is much better to make corrected RAW-conversions (I really hope you
work with RAW and 16-bit TIFFs) and restitch using the script you
I'll have a look at the others and PM you, OK?

an indicator. File size SHOULD be a big concern, because broadband speed
varies considerably from country to country and broadband speed is much
slower between continents. I therefore usually also compress the tiles
separately, compressing much more for the nadir unless there is something of
interest to see there. Usually my compression is: Pano2QTvr quality setting:
60 for Zenith (watch for banding in blue sky), 70 for four around and 40 for
nadir. I also sharpen on a separate layer and then mask out all the
