The Experiment Continues

Colne Water - Rollei ATO 2.1 exposed for 64 seconds.
Developed in Rodinol 1:300 for 13 minutes.

Last week we had a break in the weather and what a lovely little rest bite it was too.

It also meant a chance to carry on the experiment with the Micropress 5 x 4 pinhole.

So, I loaded up two sheets of film and off I trotted to a little place at the top of Colne.

The problem with the Rollei ATO is that there is no data on the reciprocity of the film therefore the experiment this time was to test for this.  The first exposure was based on the sunny 16 rule and this negative didn’t develop.  It was quite literally black.  The second exposure was based on FP4+ reciprocity and ended up with an exposure of around 64 seconds.  I reckon that this is around 3 stops under exposed so based on this assumption the exposure time should be around eight minutes and we should get somewhere close.

Although the exposure isn’t quite right it is easy to tell from the negative that the image is nice and sharp where it needs to be and should be able to produce good results.  I still have four sheets left of this film to experiment with.  Roll on the next break in the weather!
