I use an ancient Minolta SLR (almost nothing is automatic, which is the way I
like it) and a 55mm macro. This works beautifully once you get the hang of it.
In my experience some kind of light blue filter is critical for photography of
blue-toned iris flowers, especially in bright sunlight. Otherwise the blue is
several shades too red and the photos are very misleading -- you see this
effect all the time at slide shows and even in some publications where the
photographer/author probably should know better. I use an 82A filter (light
blue) and have been very happy with its effects. You can check out the results
in TSI since I have a close relationship to the editor and she frequently uses
photographs I've taken. The annoying thing is that you need to take the filter
off in photographing red-violet or yellow irises or they will appear too blue.
Taking pictures in subdued light/shade cuts out the amount of ultraviolet
radiation which is causing the reddening effect and you can sometimes get away
without a filter, but then you have to use a faster film.... What we really
need is an accurate color film with the same sensitivity as the human eye, but
none exist and probably never will. I haven't done very much with digital
cameras and irises because it's still too expensive to get a digital projector
for presentations, but I would be interested to know whether this reddening of
blue tones occurs there too. Probably not I would guess, and that might be the
final solution to the problem. Snow on snow here, but the plants are sleeping
cozily beneath the blanket. Bob Hollingworth

I just attend a presentation by Bill Maryott on photographing irises. He
stated that any of the popular cameras are fine for the type of photography
we are doing. He recommended a 55 mm Macro, a tripod and an 80B filter to
correct Kodak film for the blue/violet/purple colors.
I have a Minolta Maxuum 7000 (old auto everything) with a 35-70 lens that
has a macro feature. Works fine for me. I put on Aperture priority, adjust
aperture until speed is 1/60 to 1/45 and hand shoot. Not sophisticated as my
photography knowledge is very limited but works fine. Just purchased 80B
filter so can't say about that yet. I do know that 100 ASA Kodacolor Kodak
film is rarely even close to accurate with blue/violet/purples.
