OT: Color Photography

From: Sharon McAllister <73372.1745@compuserve.com>

I'm still playing catch-up with e-mail, but haven't seen any mention of the
use of color charts in the discussion of how to obtain faithful
reproduction of the blue tones in iris so thought I should chime in.  

I shoot the MacBeth Color Chart as the first frame of each roll, and note
that fact when sending the film to the lab.  The lab uses that chart as a
reference and I get good color balance.  If a color still doesn't come out
right, that frame can be reprinted with corrections if accompanied by the
frame with the chart on it.  It's a standard chart used by photographers --
not the RHS chips.  This is NOT something the one-hour labs will do, but
I've had excellent results from the Kodak lab I've used.

Most of my photography is for seedling records, so consistency is extremely
important.  I make a point of shooting the entire roll of film under
similar lighting conditions, and even try to shoot at the same time of day
to make day-to-day comparisons easier.

Blue is the most challenging hue, although I also have problems in getting
the leaf-green markings on some aribreds to show up clearly.   This is
where the RHS charts come in.  When I select a seedling, I use the RHS
charts in recording its description -- if the picture doesn't closely
approximate those chips, I know there's a problem.
