***SPAM*** Re: [APML] Advice, suggestions needed on new images

["Don Westergren" <westergren@netzero.net>]

Hi Alan,

I think you are seeing the results of a film that has uneven color response.
My film test of Fuji SHQ200 show low red response compared to green and blue
out to 136 minutes, then the green falls off out to 273 minutes.  Can it be
repaired?  Try increasing the red in PhotoShop.  It may compensate OK.

You might look at Joe Mize's web site at http://www.cav-sfo.com/.  He has
some very good long shots using Fuji SHQ200, taken with a Tokai DS filter.
I think the use of that filter enables a balanced color response and better
pictures.

Good Luck,
Don
