Re: Adobe Gamma, monitor contrast, and tagged files



Today I have my first prints to the 1200 (since upgrading to full PS 5) that
are a dead ringer for the monitor image!  Hooray!!  This with the monitor
contrast at half (50 out of 100) before running Adobe Gamma, then leaving it
there throughout.  The brightness setting ends up at at 20 (out of 100) when
I begin Adobe Gamma at contrast 50.  The difference from yesterday is that
I've made more accurate color management choices in RGB setup and the
printer dialogue box, thanks to Ian Lyons and his article on configuring the
color management system in Photoshop 5 at
http://www.magix.com.sg/users/kltham/ .  I recommend this and his earlier
article, Using the Photo 750/1200 with Photoshop 5 to any Windows users
still struggling with this stuff.

Lipmanson and Moss both report monitor settings that differ considerably
from my current however, and I'm still not sure if corrections applied to an
image on my (mis?) calibrated monitor (by running Adobe Gamma with the
monitor contrast turned down considerably from the recommended maximum) will
read the same on another calibrated Photoshop 5 system.

Answers/opinions welcome!

Thanks,

Dave
