Need help using RH Designs Analyser Pro for film calibration

[Andreac76]

Hi everyone..
I would love to use the densitometer mode in my RH Design Analyzer pro to build my own HD curves. My goal would be to find my normal developing time for my films.

Is it even possible?

Thanks
Andrea

Thank you for your reply
Actually I need to test films in 35 mm. So I did my exposure in zone V and I started from zone I increasing by 1/3 of a stop. Now I have a range of exposure to test for the d0,9 of the paper to find my ISO. Once I’ve found my ISO I do the same process for the zone IX to find the d0,04 (off withe in the paper).
That is my method. Instead of printing test stripe can I use the densitometer of the RH Analyzer to find the 0.11 frame? Is it accurate enough?
I would also use it to find the gamma of my negative adjusting the developing time consequently.

Just to be clear I enjoy spending more time in printing my photo rather than testing my negs but I think that testing is a way to have more control and awareness of what we do every time we open the shutter.
