Oliver, it doesn't seem likely that the scanning would cause consistently 
over bright images. It would be possible and the scanner
calculated exposure is subjective just as is printing from colour neg. But 
if it's an auto exposure decision by the scanner it
should not have got it wrong over a whole range of images over multiple 
films. You could make it happen by making an exposure
setting then locking it for all frames, but that would not be a typical or 
sensible set up.

My suspicion is definitely on the viewing set up, being monitor settings as 
well as ambient light.
Unless that is a known state you can not predict how an image adjusted to 
look correct on that screen will look, either as a print
or an on-line image. Colour management is everything in this endeavour.

Given the exposure tolerance of colour neg, even some consistent error might 
not to be showing up in the prints. That is the
printing process will adjust the exposure to normal or closer.
And your lab has said that your initial exposure was correct.

If you get your set up calibrated and do find that the scans appear 
consistently light, or more likely the versions down-sampled to
make the posted images too light, you ought to be able to apply a consistent 
correction to each. I'm assuming Photoshop here, a
correction curve on an adjustment layer to fix the first image can be 
dragged onto every other image without having to correct each
image individually. If that's been poorly explained, drop me a line and I 
shall try to be more clear.

Cheers
Hoppy

Thanks to everyone who took the trouble to comment. It seems that the
majority of the viewers consider most of the images to be too bright and/or
lacking in saturation:


A friend lent me his Gretag but I haven't properly calibrated my CRT yet
because (add excuse of your choice). I finished scanning my 15 rolls of
Optima 100 from the trip about 6 weeks ago, and I'm not going to rescan the
whole bunch although I may rescan selected images for comparison purposes.
The pro lab that does my C-41 processing looked at the negs and said that
they are correctly exposed. Could the perceived excessive brightness
originate in the scanning process?

Thanks again to everyone,
Oliver
