Digital BW, The Print

Hi all

I've been on this list for a while, trying to make a decide whether 
the time has come to ditch the black and white darkroom.  My inaction 
has been compounded by some health problems of my own and of an 
elderly family member who I have to look after.

However, I've come to realise that my life is a case of running to 
stand still most of the time.  So it's time to give it a go.

I've decided to try MIS VM in an 1160.  My G4 set in the 1160 and 3rd 
party dyes in the 1290 just don't cut it for black and white.

What I'm uncertain about is the greyscale working space to use.  My 
PS colour preferences are set to US prepress defaults (dot gain 
20%).  However, I remember reading somewhere about using grey gamma 
2.2.  Why would that be so?

I keep my monitor set to 2.2 for two reasons:

1. when editing video, it displays an image closer to tv gamma.
2. when viewing on the web, I assume most images are done at 2.2 gamma.


Of course it's kind of a moot point for photography and printing as
photoshop automatically converts from the working space to the monitor space
on the fly, making images in 1.8 working spaces look the same as images in
2.2 spaces on both 1.8 and 2.2 monitors.

The main difference is the way in which the curves controls (and others) in
photoshop effect an image.  The same curve will effect a 1.8 workspace image
in a different way than a 2.2 workspace image.

I learned this lesson converting working spaces with adjustment layers not
yet rendered and the  conversion changed the look of the image on screen.  I
now flatten before conversions.

So Jerry, if you changed your monitor to 2.2 you wouldn't need to reprofile
anything at all, except your monitor. The monitor profile is not in the loop
for printing from photoshop, just the working space (source profile) and the
printer space (destination profile).
