i know there are filter kits for exposing the same frame with different images,like those of cokin. My question is how should i set the exposure? under how many stops for each image? thanks

well, as far as you don't expose the same part of the film multiple times, you can go for correct exposure. but for exposing the same part multiple times you have to underexpose the film with the same stops. for example if you are exposing a film of ISO 100 for two times, underexpose it by one stops for every exposure so that the sum of all the exposures will correspond to correct exposure (or under/over exposure if you wish to push/pull the film). or you can expose the film twice as 1/2 stop + 1 and 1/2 stop depending on the subject for each exposure. but be careful that you are aware of the metering modes. because a correct exposure for evaluative metering might be overexposure for stop metering. so taking all factors into account you decide the stops for each exposure.

If you are using a multi-image filter you don't change or compensate the exposure at all.

i suggest u lock up the exposure reading before covering part of the lens or underexpose it by 1-stop when the reading is taken after covering.
