Heather, 

I just had a look at your IR pic. Great subject for IR and a nice
composition, but very grainy indeed. Besides that IMHO the print (or the
scan ?) is altogether a bit low contrast. But of course that's a matter
of personal taste...

Another thing - the following remark in one of your previous mails made
me think:

You didn't set your camera's meter to ISO 50 and meter through the
filter, did you? If you did, this would explain the graininess and low
contrast of your pic - heavy overexposure...;-) When metering THROUGH a
Wratten #25 red filter, I'd suggest ISO 250 as a starting point
(personally I use ISO 320 during summer). ISO 50 to ISO 64 is correct,
if you meter WITHOUT the filter in place respectively with an external
meter.

All the best,

Eckhard
