hi im shooting a super 8mm sequence and have a few concerns that someone may be able to help me with.

My camera can only use 40T asa and the film im using is 64t echtachrome reversal-- as I understand it- this will mean my footage will be overexposed--

apart from pull processing (im not sure who offers this) can anyone recommend what I can do in terms of obtaining a neutral density filter and what the correct one would be to buy.

My camera, a halina super 8, has no manual exposure or metering and its automatic settings cannot be over riden, and it has cds electric eye metering as opposed to through its lense

Hope someone can help!
