When buying enlarger lenses, it is important not only to choose a lens of the right focal length to give the required magnification, but also sufficient coverage to cover the negative without vignetting. The rule of thumb with enlarger lenses is: Focal length Typical coverage 50mm 35mm 75-80mm 6×6 100-110mm 6×9 150mm 5×4″ I decided to […]Read more "Testing enlarger lens coverage"
There’s a bewildering choice of microphone types available and it can be hard to know which type of microphone to choose, let alone which make and model within that type. I grabbed one of each of my microphones and performed a simultaneous microphone test on various test sounds. Maybe this unscientific video test will even […]Read more "Multi-microphone test"
Some time ago I compared the EF and FD versions of the Canon 50mm f/1.8 lens. It wasn’t exactly a fair test because the EF lens fits natively on my DSLR, while the FD lens needs an adapter with an optic. Now I am fortunate enough to own a Canon EOS M mirrorless digital camera which can […]Read more "Lens test: Canon FL, FD and EF 50mm f/1.4 vs f/1.8"
Toning a black & white print is a dark art (and one that I’m just beginning to learn). So many different toners exist and can be used to create different coloured tints according to the concentration, temperature, time taken and combination of multiple toners that it is hard to know where to start. To make […]Read more "Testing toners"
This article is about something I should have done long, long ago. I regularly use Ilford FP4+ as my “standard” film but I don’t really know exactly how it behaves in different developers. It behaves nicely in all Ilford developers but for my purposes (mostly landscape photography) I would usually pull by about one stop […]Read more "Development test"
After making some pinholes recently, I tested them with my DSLR. It has a tiny sensor and it’s not even the camera I intended to use the pinholes with. So naturally I’ve now tested them with my Horseman 980 view camera, which has a sensor area sixteen times greater than a crop-sensor DSLR. I was […]Read more "Second pinhole test"
Recently I wrote about making a pinhole lens for my view camera. The results weren’t brilliant and I wondered if I had chosen the right diameter of pinhole. So I asked laser dude to cut some more pinholes in other sizes, and now I have 0.2mm, 0.3mm, 0.4mm and 0.5mm pinholes, all mounted in 80mm […]Read more "Pinhole test"
