Haven’t used the 4x5 field camera in a while. It’s a Jungwoo 45, with a D.O. Industries 150mm f5.6 Navitar lens in a Copal 0 shutter.
I used a Sekonic light meter. This meter is a little pricey, but it’s awesome.
I’m shooting my usual staple for 4x5 – Shanghai Pan 100 (aka GP3 – though GP3 is only really the name for this film when it’s sold in 120 format as far as I understand). I like shooting 2 stops down from wide open, which in this case is f/11. This gives a 2s exposure.
With reciprocity taken into account, that comes out at 8s.
The tarn was like glass – there was no wind at all.
