The Agat 18K is a nice rustic russian half frame cam. A simply instrument that works pretty enough with all the manual controls you can need to take a photo but bulb position and lightmeter. To proof this cam I loaded it with a Kodak Plus-X pan 125 film roll for about two years. In fact this kind of cam is worth as a diary's camera. A nice girlfriend gift me this roll in Paris, in 2010. I developed it with HC-110 (dil. B) for around 7 minutes -agitation for 5 seconds every 30 seconds-. I think now it was too much, because the developing veil in the film. I'm just starting with this and a expired film is not always an easy test to learn how it works. Thanks to professor Neira of the School of Arts and Trades Pablo Picasso, who let me to work freely at the school's laboratory.
