Introduction I’ve been a photographer for 35 years since I was 11 in fact when I first loaded my Zenith 11 with film and set off for a walk into the wilds of South Yorkshire. 20 years later I turned professional and as soon as digital became a viable option I traded in my Nikon F90x and Mamiya 645 pro for a Nikon digital kit. Digital was for me always a triumph of convenience over real quality in those early years and not much else. It wasn’t until Canon brought out the 5D series that I found myself ...

An experiment in chemical possibilities When I took up a camera after a few years’ hiatus in 1990, I was surprised to discover that I could no longer get a black & white film developed through the nearest camera shop, never mind through the local pharmacy.  If memory serves, I was told it would cost $40 for a single film. Naturally, I returned to processing my own film just I had done when I first took up a camera in the early 1970s. The world had moved on, and colour film was the default medium f...

Turning your negatives into positives Reversal processing enables black and white transparencies to be produced directly from high quality films such as PAN F Plus, FP4 Plus and DELTA 100 PROFESSIONAL How it works It starts with the development of the negative image. This leaves the unused silver halide untouched, but it is not fixed, as it will be used later to form the positive image. After the negative image has been developed, it is totally bleached away using an acid bleach. This leaves the remainin...

Below are some of the common errors that can occur when processing black and white films. Unfortunately some of these errors can result in the images being lost or partially ruined. By knowing what has caused the errors, you may hopefully prevent any repeat incidents. Film entirely blank - No visible images or edge signing A completely blank film with no images and no signing (i.e text in the perforation areas showing product and numbers) - indicates the film has received no development at all. Blank ...

The Photography Show 14-17 March There's not long to go until this years Photography Show at the NEC in Birmingham and it's going to be a great one. (If we do say so ourselves)! There is going to be a far greater analogue / film presence at the show this year as the organisers have agreed to the inclusion of a dedicated ‘Analogue Spotlight’ area which will include some pods for smaller brands and a spotlight speaker area for those brands to do demos.

The future of photography The year 2020, it sounds very futuristic to me. So, what does that future look like for photographers? Well, no doubt technology will be getting more advanced than ever and we will see huge leaps in digital development this coming decade as the megapixel war continues. There will likely be be new initiatives and more collaborations with smartphone companies. Will the digital SLR camera start to disappear? Will mirrorless take over? Or will there be a new hybrid on the market...
