pictures that my daughter took with this lens a year ago seem reasonable. It

Hi all,
Some weeks ago I put some pictures of reflectors I've been using used for
macro-photography with flash on my web site. I've just put them back. The
bottom row are close-ups taken using the reflector contraption seen
attached to the P30T.
How do you keep the Epson jets clean? I found that I used so much ink
cleaning the bloody thing that it became a financial burden. It sits here
doing nothing now.

The reciprocity effect is only important for exposures of several minutes.
For normal applications it can be ignored. When recording diffraction
patterns on an optical bench for example, where exposures may be as long as
fifteen minutes, the effect becomes serious. But in this case the film and
How can you say that Wheatfield Willie is right? That C41 can't be pushed?
I've just carried out a well controlled experiment and the results show
unequivocally that it can be pushed quite nicely. Take a look.

Right - ladies and gentlemen,
More information.

with Solaris FG400 film.
I'll keep this simple and non-technical as far as possible. It
would take some pages to give all the details. The scanner
was not calibrated, I have no means of
Processing Ferrania Solaris FG400 for 1600 ASA.
An introduction is unnecessary since the intention is obvious.
Methods and Materials.
Film: Ferrania FG400
Camera used for test exposures: Pentax P30 with SMC Pentax-M
50/1.7 and VMC Vivitar 135/3.5.
Processing: Tetenal Colortec C-41 Rapid
and possibly the
Supras are set up so the orange mask isn't as sensitive to development
times as in other films.
Haven't tried it myself, and the mask is only half the problem.

According to the Tetenal technical people Reala 800 pushes very nicely to
3200. They recommend 30s per stop of push. My calculations were short by 7s.
I developed for 288s with developer that had already processed four films -
the normal' time would have been 3m 55s.

Try moving the film feed sprocket in the forward direction with a clean
finger. This might get the mechanism back in register. This happened to me
with three different single lens reflex cameras an ME Super and two Alpa
Reflexes.

Hi all,
I've been here, but off the list for a while. Now I'm outside crawling about
taking pictures of flowers, many being only 2-3mm diameter, as usual.
