MirkoBoeddecker The Schwarzschild values can be found on the website: http://www.adox.de/ADOX_Filme/Premium%20Line%20Films/ADOX_CMS_Filme/ADOX_CMS_Filme.html The sheet film is currently in production. The film has already been coated; we are awaiting completion of the air handling system in the sheet film assembly area (cleanroom conditions). Best regards, Mirko
CPD Hello, Unfortunately, it just says: Reziprozitätsverhalten (Schwarzschild-Effekt): Im Bereich zwischen 1/100 und 1/10 s ist keine Korrektur notwendig. Bei 1 s + 1/2 Blende Bei 1/1000 s + 1/2 Blende Best regards, CP
SxDx That sounds like "standard" behaviour. As a rule of thumb, I always use the following: Instead of 5 seconds, 10 (x2) Instead of 10 seconds, 30 (x3) Instead of 20 seconds, 80 (x4) Instead of 30 seconds, 150 (x5) That’s usually not so far off the mark that you can’t use the negative. You always have to optimise it anyway, and it also depends on the light (or rather, its colour temperature).
hagee Since the camera is mounted on a tripod anyway when using such long exposure times, I always take a series of exposures when working with unfamiliar film stock. At least the first time, when I’m not yet familiar with the film. I also make a note of what I’ve measured and the steps used for the exposure series. That way, at least one of them will be usable, and next time I’ll have a useful reference point. Best regards, Hans
