I am aware of the general advantages regarding negative latitude. How far can I push this 50 ASA negative stock? 1, 2 or 3 stops? Any scanned examples?

Cheers!

Is there any reason you wouldn't just switch over to 7207, considering the additional lab expense of pushing?

Hi Jock.

I would if I could.

However I am utilizing the UltraPan8 format which utilizes Regular 8 film (2R-1497). Specifically the full 16mm width of R8 with R8 pulldown. Here is a scanned example, i.e.

In general there only two reversal R8 (2R-1497) stocks available, E100D and Plus-x. UltraPan8 only utilizes the right side B-Wind perf for pulldown. I recently had Mr. Edward Nowill in the UK reperforate 800 FT of standard single perf 16mm V3 50D (1R-2994) into a special B-wind only R8 stock, i.e. 1R-1497.

This only usable in the UP8 format. V3 200T/500T are forthcoming. Hence my question.

Oh, I see. Right.

Well I've never pushed any of the 50D stocks myself, but I'd imagine with 7203 that you could probably get it to at least EI 200 (ie 2 stops) before you start have troubles.

Of course testing is the only option, really.
