Re: New Panoramas for critique
- Hi Erik,
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
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?

It was 16-bit tiff, extracted from RAW though, all the way to the

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
