I just bought it, and just finally opened my first roll. Very very interesting product. Very cute plastic wrapper.

The outside of the box said "instructions inside". SO i cut the box open and actually saw some very interesting things..


They have a really cute diagram of cloud coverage and what aperture to use. But the cutest thing, is that they have at teh very top of the data, is

ISO 100/27* 1/125SEC.

Hmm hmmm, it looks like they are charting it out to use the iso/shutter inverse just like hazy 8 and sunny 16 charts use.

And then they include very interesting developer data. And a rather big surprise... they list data for 400 ISO film although they box data only says GP3 Pan Film.... it doesnt say if the entire chart is 120/220 data or mixed with 135 data.

Rodinal is just shot at box speed and each standard dilution of it. Though 1:100 for the 100 iso film shot at 100 iso is a mere 25 minutes, so im thinking semi stand?

D-76 is the interesting one, the 400 iso can be pushed to 800 and 1600 ISO at stock solution.

HC-110, Xtol, and Tmax Developer are only listed for box iso. It makes me wonder why so many people are focusing on OTHER developers.
