Hello,
I had posted previously with a question about the development time for Ferrania Orto 50. I decided to go the HC110 Dilution G route. Agitate for one minute then let stand for 59 minutes, total one hour development time. I thought the results were satisfactory, the negatives were clear and comparable to panchromatic negatives. I pasted my procedure at the end of this post as a reference for others who may have the same question I had. To keep the temperature somewhat consistent I place my development tank in an old cooler with water at approximately 70 degrees, there is about a two degree drop per hour. I put the rest of my chemistry in the cooler as well so it will be at 68 when I need it.
I've made a couple of prints but will have to do some more experimenting. The structures in the prints looked okay but the lake water surrounding them looked a little odd.
I'll definitely be buying more orthochromatic film in the future! I like having access to an older film technology and eventually hope to make prints that look like they could have been taken 100+ years ago.
