Description My very first calotype.

"Shot" with an Austrian 19th century camera, aperture full open, exposure 25 minutes, on an April evening with scattered clouds. View of a mediaeval house behind a garden, original negative (above) and digitally processed positive (below).
The film I used is makeshift Calotype paper, developed with gallic acid, fixed with hypo.
Not too loosely based on W.H.F. Talbot's instructions on the calotype process, but sensitizing was achieved through brushing with silver nitrate and acetic acid solution only, using gallic acid only (without silver nitrate) in the developing stage.

Hopefully on some sunny day I will get more contrast, to be able to print a positive from the paper negative.

Thanks for appreciating... I wish I'd have stuck more to the apothecary scale than to my guessing in mixing the chemicals...

Guessing seems to have worked fine too

Sorry for having a last word here... but you're kind of right - guessing has worked fine - in one of a dozen trials... mostly because of varying amounts of the chemicals involved and the lack of a tight darkroom.

It's one of the charms of most antique methods in any kind of arts

its great that people still try and experiment with methods most commoners find as obsolete

Thanks for the appreciation! But I guess it's a bit pessimistic a view... because there already are people working with these old techniques with much better results. I'm just one of many.
