Re: [APML] Hypering RG200 (was: new post)

Thnaks for the tip.
    I have a roll I hyped for 2 hrs in the canister. I didn't have a chance
to shoot it yet though. Maybe I will just move it my "normal" film sectin in
the fridge and try it for 5 hrs.

hours/50C/standard Lumicon instructions/hand pump.  There was no noticable
change in the "rebate" between this and unhypered film.  Film response was
poor.  A one hour exposure at f/5.6 (80 mm F.L/dark skies/Nikon camera on
tracking mount) was underexposed.  My tentative conclusion is that the film
is not well hypered "in the can" with above schedule.  Next time I will try
5 hours.
