A Walk in the Park

 I shot another roll of expired Tri-X in the No.1A Pocket Kodak on a morning walk through our nearby park.  My main objective was to test a strategy for correctly spacing the frames.  I decided after advancing the film by an initial eight and one half rotations to get to the first exposure I would then give two and one half turns to get to the second frame.  From there the plan was to decrease the film advance by one quarter turn for each subsequent frame with the hope of getting six or more shots on the roll of 120 film.

Well, the first two frames looked just right.  After that the pictures started to run into each other and I ended up with just muddled fragments of images on the rest of the roll.  Not the hoped for outcome, but it was a fun outing in which I learned something, and I thought the bits and pieces still showed some of the nice qualities which the Kodak Anastigmat lens can produce.

In addition to the frame spacing problem, I also ended up having to square up most of the images in Photoshop as a result of grossly tilted horizons.  For that, I'm blaming the use of the tiny reflex finder which seems to aggravate my tendency to misperceive which way is up.  So, for my next outing I'll try using the open frame finder which I usually tape onto the top of my folders, as well as a revised film advance routine.

The one thing I'm pleased to report was not a problem was focal distance estimation.  Snapping pictures under the full Summer sun with a top shutter speed of 1/50 and 400 speed film, the correct aperture setting is f45.  Having consulted a dof calculator before setting out, I knew that the hyperfocal distance for the 127mm lens at that setting was seventeen feet, and that everything from 8.5 feet to infinity would be sharply focused.  For some of the closer shots and with the aperture a stop or two wider the available depth of focus was still well within my margin of error for distance estimation.
