Re: Preliminary Results:SFX & Maco w/092 in Xtol 1:2 Jobo processing

[Fred Greenspan <greenspan@xxxxxxxxxxxxx>]

Those who followed my filter adventures know I received a replacement B+W 092
this morning. Today I shot one roll each SFX200 and Macophot, both in 120
format. I loaded in complete darkness in Rolleiflex 2.8E & 2.8E2, both of
which have autoloading, so I didn't need to line up the arrow with a mark in
the camera. I also unloaded the film from the camera and loaded directly into
processing tank. I know this is probably unnecessary, but just an added
initial precaution.

My development test is loosely based on the one in Kodak's Advanced Black &
White Photography. I take a reflected meter reading, using manufacturers
suggested EV, off a grey matte board outside in even lighting.
I open up two stops and take a picture, without any filter, filling the frame
with the grey board. After processing I take a density reading and subtract
base + fog. Kodak suggests a density of 1.05 for a diffusion enlarger, and
0.80 if you have a condenser enlarger. I use a VC coldlight and prefer a
negative density between the two suggested for my printing. Usually around 95.
This is a very loose test and I am only posting it to give others a starting
place for rotary processing these films with Xtol.

Here are my results using Xtol 1:2 for 12 minutes @75F using a Jobo CPE2
Rotary processor, no presoaking:

Macophot 0.73 over b+f. Too thin. I will try again in the next few days using
14 minutes.

Ilford SFX200 1.34 over b+f. Too dense. I will try again using 9 minutes next time.

I'll let the list know the results of these newer times.

A B+W 092 was used for the rest of the images on the two rolls. Scenes were of
my wooded backyard with sky on an overcast winter day at 3:00 p.m. All
readings were incident, taken with hand held Sekonic meter.

The Macophot seemed to be around EV3 including 092 factor, give or take a stop
depending on personal preference and amount of IR in scene.

The SFX200 seemed to be around EV 50 or 25 depending again on personal
preference and amount of IR in scene.

I will have a better idea once I start printing. I hope this helps others and
gives a starting place for individual testing. Regards, Fred
