Edward,
This is a very interesting question. In general, I believe an L*=50
many thanks for your response, roger.
equivalent would be best to avoid any unforeseen adaptation issues.
It seems to be the way it is harcoded in Photoshop -- haven't found
the
interface to change that parameter yet?
I know some people advocate using a 1 inch white border around
images to
help set the chromatic adaptation to the monitor's white point,
however it
is managed. And I agree this trick makes sense when softproofing
against a
hardcopy proof, viewed under a light booth of some kind.
let me elaborate w/ a hypothetical scenario:
assume you're pre-softproof & you'll have the capability to add
simulated media
when you're ready; you're laying-out a group of images, in the same
window; the
images are of similar composition, both subject & light, e.g. a
catalog spread.
you're attempting to focus on the images as a group & you have the
capability to adjust the background.
how would you tweak the background relative to the images & environment?
best regards,
edward
But if I'm worried about the effect such a high brightness stimulus
around
an image has on our adaptation. As you know, all movies are gamma-
corrected
to compensate for the fact that theaters are rather dark places to
view
images and, apparently (it's been demonstrated scientifically), the
visual
systems respond with a decrease in perceived contrast in those
environments.
So, to me, viewing images with a white border around it would tend to
artificially increase an image perceived contrast.
That's my take (I hope I don't have this reverse).
At any rate, I suspect this is a relatively easy effect to test
using the
same image viewed side by side (assuming uniform Luminance and
chromaticity
across the screen) in two document windows in Photoshop, setup to
different
borders. You can try black and white first (the two extremes) and
then gray.

does anyone have experience with or opinions about the selection
of a neutral for use as background fill of a window? or: how should
the background be tweaked to attain optimal viewing of photos/images
of different type under different conditions?
any suggestions/favorites (lab or tagged rgb coordinates) paired with
scenario greatly appreciated.
thanks in advance,
edward taffel
