[Leica] Monitor brightness issues

[oliverbryk at comcast.net (Oliver Bryk)]

Several of our colleagues have been kind enough to call my attention to the
fact that some of my recently posted pictures are too bright, lack contrast,
show blown-out sky, or show similar discrepancies on their CRTs and/or LCDs.


I am asking for suggestions regarding the source(s) of these visual issues
because I do not see them on my CRT monitor, a 5-year old Gateway 19" VX900,
possibly a rebranded Hitachi. The adapter is a NVIDIA GEForce 2 MX400 with
the latest software release. I calibrate the monitor about once a month,
using the Nokia screen test software. I have my vision tested annually. I
edit my pictures in a room with very low ambient brightness, with the shades
drawn. My screen background is middle gray; the screen setting is 1024x768,
32-bit color. I scan the negatives at 2000ppi on a Nikon 4000 with the
current release of VueScan, save and edit them as TIFs, and convert to JPG
as the last step before transmitting them. The brightness of the scenes on
my monitor matches my memory of the location. I made the images in question
under fairly bright conditions, typically f/8 or f/9, at 1/250 on Optima
100, dependably a real ISO 100 film. I did not include a color reference
chart.

I do not have the technical or scientific background to fully understand
what, if anything, is happening to the colors in the sequence of
transformations, and what might account for the differences in perceptions.
I shall be grateful for suggestions and/or explanations.

Oliver
