Hi Guys Looking to get some advise on exposure times on long exposure for hasselblad 500CM when using EV values taken from Sekonic light meter. I was in a situation the other day with very low light as was before sunrise. My light meter gave me a EV value of 3 which equates to B on my 50mm F4 lens. EV 4 = F4 @ 1 second Anyway it was very dark, I wanted a long exposure as was photographing storm waves in Cornwall. So did a few shots testing with 20 Elephants or was is 20 Mississip's can not remember. Any way the photo came out well. Please see attached. My point is i am looking to get some dark ND filter, Big stoppers @ 10 F stops. How many seconds would this equate too, i have seen various charts, but hard to see as my lens only goes down to 1 second shutter as all settings built into the hasselblad lenses. Would love some easy to follow advice. Cheers Pete
