Comments

These are suggestions and approximations only. Times are based on film being used in warm weather so adjust accordingly for cold weather. Film emulsions are constantly being changed or updated by manufactures, and this can at times radically change how a film reacts to hypering.

These times are based on open reel hypering. 120 film generally should not be hypered with the paper backing still attached. 35mm film can be succesfully hypered when left in the canister according to some reports. Conventional wisdom is to as 20 to 35% more time when hypering if left in the canister.

NOTES

.

N1 - Elite II is extremely sensitive to mercury vapour lamps. When hypered, it will exhibit a very strong green cast. I had one film turn greener than Kermit the Frog on St. Patrick's day. I recommend hypering only when used in extremely dark skies. Even unhypred it is still sensitive to mercury vapour.
