I have figured out a way to use the Hasselblad with my digital back to make the photographs for this series. Really I would like to do it on film but the turnaround time is very slow. I have enrolled on a course at the CityLit which is in November to learn more about processing my own film which might speed things up a bit. It took 2 weeks to get my black and white films, which I shot during my trip to the US, developed and scanned!! I am also going to try another lab in central London – West End Cameras.
In the meantime using the digital back will help me to formulate how I plan to carry out the assignment….I certainly need some rapid feedback.
Here is a self portrait made with the digital back, Hasselblad and pinhole adapter…it was a 50 second exposure which is about the same as the exposure times for the early Calotypes.

The definition of the facial features is much better with the digital back and by keeping the exposure time down to about a minute or so. I sometimes wonder why I am doing so many self portraits. Truth is that I need a subject and those around me run for cover when I get my camera out….I can’t really escape! Here is a self portrait by David Octavius Hill…

Hi Keith
I have been thinking about using my Hasselblad and a Credo digital back with a pinhole but I have not worked out how to trip the digital back. Obviously, you have! Well done!
Do you mind sharing how you do it.
Next, will come questions about how/where you sourced the pinhole!
