Film Development Test for Black and White Large Format (4x5) Ilford FP4+

Image
Introduction I want to start fresh on my Black and White photography. This is part of my effort improve in all areas of my photography.  In this post I want to concentrate on large format film exposure and developing. I want to follow a zone based system of exposure and development that utilizes my spot meter (as that is the meter I will mostly use) my choice of medium speed Black and White film (Ilford FP4+) and single shot developer (Kodak HC-110). My rationale for single shot developer and choice of HC-110 is laid out in this  previous pos t. First I need to create a zone-based test pattern. I reasoned that if I could do this all in camera it would be cheaper and easier than using a specific target. The methodology I figured out on my own though I doubt I am the first to think of it. The methodology is to aim the camera on an artificially lit uniform surface of uniform brightness. I then use the darkslide to progressively expose the entire sheet of film. I do this u...

Russian Spy Film (16mm photography)

The 65 number refers to the Soviet film speed which elsewhere on the box is translated to 80 ASA and 20 DIN.

The first roll of film I exposed using a flash  on automatic mode with a speed of 100 (The Russian film is actually ASA 80). I also developed using semi-stand development with a solution of 1+100 Ilford LC29 developer. Stand for 30 Minutes, invert and stand for a another 30 minutes. Stop and fix per usual. The results were under exposed and grainy. The film had some fog as well. The scan below shows one result and this is after optimizing for levels in Photoshop. Stand Developed Russian 16mm scan. I thought the development was not good for this film and wanted to see where the film speed was best set for. I loaded and shot a new roll. This time...
