I will not reveal anything new to experienced darkroom technicians. When printing photos in a darkroom, we can use photo papers in three degrees of gradation. Soft, normal and hard. Or we use multigradation papers, when we control the gradation of the resulting photo using filters. We use the yellow filters to reduce the gradation and the purple filters to increase the gradation.
Pentacon Six TL + CZ Biometar 50mm Zebra
TK100 + MP271
MG Fomabrom Variant & Fomabrom C112 + Dektol
The first photo was exposed for 4 x 3 sec. total 12 sec. The first 9 seconds were with the use of a yellow filter and the last 3 seconds without a filter on MG papers Fomabrom Variant
The second photo was a 9.sec print on ordinary Fomabrom C112 with hard gradation….
The final version of the own two-bath negative developer was named MP 271. At the moment, it is only tested on Fomapan 100 negatives. It achieves slightly better results on 35mm negatives, which is fine with me, because this is how I radically reduce the costs of analog photography 🙃📷
In the upper part of the linear scan of the negative, it is shown how it develops the first bath.(correct,-1EV,+1EV) At the bottom of the picture is the negative after the complete chemical process .(correct,-1EV,+1EV) .
The second image is a linear scan of the negative at the correct exposure.
The following picture is from this morning in medium format
I recently tested the behavior of TK100 roll film with D76 developer. TK100 is essentially Fomapan 100, but bought by the meter. This means that you can roll a 1-frame film under the cover strip yourself, or you can roll a 220 roll if you have a camera that allows you to take up to 24 frames in the 6×6 format. Because I needed to test the Kodak D76 (Ilford ID11) developers I had mixed, I always got by with four images in a roll, for each attempt of a differently lit scene.
Nikon P 2,8/75mm
The picture is taken in the dark garage of an old repair plant. However, a fifteen second exposure allowed me to capture as much reflected light as possible.
