Category: Methods Section

Similar to a scientific journal publication, the methods used to conduct an experiment or test are described in the “methods section”. In the main post I discuss the results, while the details of the tests are left for the interested reader and for later reference.

Method: Correcting perspective in the darkroom

Rule number 1 of using wide angle lenses is to keep the film plane parallel to the subject. This rule, however, is more often than not promptly broken, as it is impossible to get the composition you want without tilting the lens up or down. With the lack of tilt- and shift movements on the camera, we have to make a compromise here between the composition and accepting that lines, which used to be nicely parallel, are now all of a sudden converging. Without breaking the bank, the digital photographer just has to dive into his or her favorite photo…

Method: storage of photographic film

Say, you just bought 10 rolls of film and plan to shoot them in the coming year. Or you have multiple printing papers that you use, some of which you use seldom. How do you store these properly and how do you keep them from developing undesired artifacts, such as a change in sensitivity (speed), contrast, color balance and fog level? Browsing the online photography fora will bring you a plethora of opinions and experiences with regard to the proper storage of unexposed photographic material. Some people claim that film that had been stored in a freezer for 28 years…

Method: Testing old paper

Two weeks ago I was given an old box of Agfa Brovira-Speed BN312PE, grade 3 paper. It has been sitting in a cupboard on an attic for at least 15 years under less than ideal conditions. To determine if the paper is still of any use, I tested it for fogging and checked how it responded to anti-fogging measures. In this Method Section, I will briefly explain how I went about testing this paper and my conclusions. If you have any tips or tricks, drop me a line! I’d be happy to hear! How to test for fogging? A fog test…

Method: making truthful reproductions of prints

Disclaimer, 22 december 2015: Only recently I realized that the variations measured are in tens of stops. F5.6 7 on the meter means is F/5.6 + 2/3 stop or F/7.1, rather than close to F/5.7. This make the measured deviations and gradients considerably larger. With proper illumination these gradients can still be eliminated. Making wet prints is at the heart of what I do here, but what would a photography blog be without photos of the prints I make? The first thing that might come to mind is simply putting the print onto a flatbed scanner. A proper photo scanner will…
