Thank you very much all.
In total fairness, she is very patient with me most of the time.
A lot more then I am when she is doing her stuff
I have to say that these are the first photos I have taken with the 645 that make me thing - yes there is a difference with the 35mm.
I am not sure if it is due to the use of a different development, the light quality that day or simply the learning curve.
In any case, I like the concept of stand development so I will need to experiment with Perceptol and stand development.
I do not have any clear guidelines as for Rodinal so it will be a little bit of an adventure
Cheers,
Luc
