Happy New Year Karl Gustaf and Nice to meet you.

Thank you for excellent tip. I know American Explorer and Photographer William Henry Jackson was using Glass 1 ASA Negatives. Details were better than todays Hasselblad pictures.

Do you think I could get similar detail from 4 ASA or is it just only slow and thats it ? I always loved the idea to use extremelly low asa films and here it is .

I will use lens with 35mm SLR Body and a Homemade Camera , 6x10 cms or wider if it is possible. When I put semi transparent paper , everything is very clear. I looked to the face of my mothers and I didnt see such a wild detail in my life , even Summmitar , Elmar and Summicron.
