Automatic metering with Kodak's new 100D 8mm stock

How, then, would XL cameras deal with Tri-X? Would there be a similar problem with an underexposure of 2/3 an f/stop?

Depends on the camera. Tri-X is notched at ASA 250 in a filter "notchless" cartridge, so if the camera can read as high as 250 it will be exposed correctly at ASA 160.

 

Any other camera, just cut a filter notch in the cartridge. That way it will be sure to read at ASA 160-- without the notchless lower ASA trick. If the camera can only go as high as 160, then any higher ASA film will be registered at ASA 160 too.

 

Without a filter notch, there is the possibility that Tri-X will be read at ASA 100, due to the filter pin kickdown.

 

Some XL cameras that only went up to 160 disabled this kickdown function, so that they could read correctly the higher speed daylight cartridged films like Tri-X and 'G.'

Auto Cameras will read Ektachrome 100D just fine. Manual Exposure cameras need adjusted. Watch here:
