Chinon 722-P

[super8newbie]

Hi all, 100% newbie here, nice to meet you,

Here is my situation:

I have come into possession of a chinon 722-P

I am aware that this camera was built at a time when most super 8 film was balanced for indoor use. Because of this (like a lot of super 8 cameras) this camera has a built in 85 filter in order to compensate for the usual tungsten balanced film. This filter can be pushed aside with the use of a little screw-in button thing for when indoor shooting is desired.

I shot a cartridge of Ektachrome 64T and found it worked just fine HOWEVER I have (stupidly) acquired some Ektachrome 100D film.

This is, as I'm sure you are all aware, daylight balanced, so no 85 filter is required if you are shooting in daylight. No problem so far as I can push mine aside

My problem is:

In pushing aside my internal filter, will the camera think i am filming inside and so give me the wrong exposure setting? It is an auto exposure camera...

If so, will it be seriously damaging to the result?

Assuming this is the case, what is my best option:

1. Leave the orange filter in and get an overly warm (but correctly exposed) image
2. Remove filter for correct color, but have an under exposed image (I think I'm right in saying it would be underexposed??)

I do hope this all makes sense

PS Inside the cartridge-space, there reads:

daylight ASA 25 100
artificial light ASA 40 160

I am assuming these are the exposure settings it automatically gives itself depending on whether I have the internal filter 'on' or 'off'....?

If the filter is before the auto-exposure eye, then it should not matter, unless moving the filter also causes the camera's auto-exposure to change. If you want to do a test on your first cartridge of film, do the filter change while the camera is actually running, go back and forth a couple of times and then when you get the footage back study to see if anything noticeably changed.
