This is a technical follow up on my post showing examples of stand processed film.
Several readers were interested in seeing comparisons between stand processed negatives versus normally processed negatives.
I made these photos in the back yard to demonstrate the differences between processed negatives. This is intended to show differences in the amount of information presented and changes in tonality.
Although there are slight differences in the composition of the scene, these variations are irrelevant for this presentation.
All exposures were made on 120-size Kodak Tri-X roll film using a Rolleiflex Model T with 75mm Zeiss Tessar lens, set at f22 1/60thof second.
Photos are grouped with both the positive scan of the original negative (to show how the black & white negatives appear without reversal) and the digitally reversed ‘positive’, that appears as would a print of the negative. Photos have NOT been altered except for scaling. There have been no adjustments to gamma, density, etc.
Details of the differences in processing are indicated in the captions.
This is a work in progress.
Normal process:
Kodak Tri-X processed in HC110 dilution B (1-32) at 68F for a total of 9 minutes in two baths. Agitation 3 inversions every 30 seconds. No post processing adjustment or manipulation.Reversal of the above negative: Normal process.
Low Contrast Process, using normal dilution and agitation.
Low contrast process: Kodak Tri-X processed in HC110 dilution B (1-32) at 67F for a total of 8 minutes in one bath. Agitation 3 inversions every 30 seconds. No post processing adjustment or manipulation.Reversal of the image above—Low contrast process: Kodak Tri-X processed in HC110 dilution B (1-32) at 67F for a total of 8 minutes in one bath. Agitation 3 inversions every 30 seconds. No post processing adjustment or manipulation.
Stand process without toning.
Stand process: HC110 mixed 4 ml to 500 ml of water plus special additives to minimize the cumulative effects of chemical fogging; 10 seconds agitation at beginning of process, stand for 1 hour at 72F, process as normal through wash cycle. No toning.Several scan of the above negative> Stand process: HC110 mixed 4 ml to 500 ml of water plus special additives to minimize the cumulative effects of chemical fogging; 10 seconds agitation at beginning of process, stand for 1 hour at 72F, process as normal through wash cycle. No toning.
Stand Process with Selenium toning to boost highlight density.
Stand process: HC110 mixed 4 ml to 500 ml of water plus special additives to minimize the cumulative effects of chemical fogging; 1o seconds agitation at beginning of process, stand for 1 hour at 72F, process as normal through wash cycle. After wash, negative treated in selenium toner (1 to 9) for 9 minutes.Several scan of the above negative> Stand process: HC110 mixed 4 ml to 500 ml of water plus special additives to minimize the cumulative effects of chemical fogging; 1o seconds agitation at beginning of process, stand for 1 hour at 72F, process as normal through wash cycle.
