Shooting Ilford Pan F 50 along Clear Creek

A very misty foggy day with low very neutral light, and slow film, add to that a 10 stop Neutral Density filter and I had a pretty interesting day of shooting and processing.  The foot bridge image was taken with a Bronica ETRSi with the 40mm lens.  I was shooting at F:22 as I wanted everything in the frame to be as well focused as possible.  I later found a problem that I don't usually try to account for during processing that I will discuss later.  Using a Vivitar Variable Neutral Density Filter (NDX) was an attempt to provide more shadow detail and less contrast as I was shooting up at the sky from a tripod set approximately 1 foot from the ground.  There was enough light scatter in the sky to make my incidental meter read EV of 17 - 18.  So I used a spot meter to read the undersides of the bridge beams, and placed those between Zone III and IV. at EV 15.  My spot reading for shutter speed at F:22 was 1/2 second. I  set my shutter to Bulb and kept it open for 1 min.  (This was approximately 7 stops?)

The processing headache encountered later aside from the usual dust was that the lens correction for this image due to the location of the camera and proximity to the bridge was extreme to say the least.  

I processed this image in Caffenol STD for 7min and 45 seconds.  The negatives looked EXTREMELY thin and very pink.  When looking at the Zoomed image in Epson Scan however they were quite contrasty.  I was very happy with the detail given the film.  I do not shoot Ilford films very often so I did not know what to expect.

This image was taken a small distance up stream from the bridge scene.  I again utilized the NDX filter at 8 stops this time.  The light for this shot had lessoned substantially and I was shooting down into a very dark area of the canyon with a 150mm telephoto lens on the same Bronica camera.  I measured the scene via my AE finder set at F:22 the meter returned a 1/2 second exposure duration.  I then measured the dark shadows on the near ground rocks with my spot meter and got an EV of 12 this correlated to a speed of 2 seconds at F:22.  Adding the NDX at 8 stops and a wishful correction for the 150mm lens I decided to set the shutter at Bulb again and leave it open for 10 minutes!  This is the result with only minor exposure correction but a huge amount of dust removal.  And after looking at it on my computer for a day I decided to add some contrast back in.  I think that Pan F is pretty neutral film for my taste?
