Have an old DR8mm camera I need to test out.

What should I shoot?

Since it's just a reg test and maybe some focus tests and the damned gate is stoo small to check anything with too.s, I'm just going to dev. the reversal film with Dektol.


What times should I use to get proper exposure?

Should I test exposure too?


How should I shoot a Siemens star with a double pass and account for the low EI with Dektol or an incorrect EI?

Is there a way to relate Dektol EI to the EI I'll get (50 or 100) with standard reversal processing?


I'm worried the exposure/shutter speed comuld be under or over and don't have time to rent the specialized equipment or take it apart and calibrate it myself. . .



Need to figure this out within the next 6 hours. Thanks!

Hi Karl,

by DR8 do you mean double run 8?

What's the camera? Do you not know the shutter speed?

Double Regular 8, 16fps.

I'm more concerned about the test than the exact shutter speed. 1/35 of a second versus 1/50 of a second isn't even an F/stop.


I'm looking for an ISO rating with Dektol and 7265. . .

HC-110, or D.76 would be closer to a film developer... even Rodinal. (under whatever name it is sold in your country)

I would expect the exposure to be within a stop of the reversal, see this thread http://www.filmshoot...php?f=1&t=14297

Charles, thanks for the link. Quite helpful.

Only reasson I picked out Dektol is that it is dirt cheap and works far more quickly. It's just a slop test anyway.

Every now and then I get out one of the subminature (16mm Still Cameras) where grain performance is important.
