Hey guys. I`m having a lot of trouble coming up with exposure times. One of the problems is that I`m certain that the light meter I`m using isn`t giving me accurate enough times. This is because I`m trying to use it to meter through ND filters (edit: not real ND filters but a welders glass), which I can`t put flush up to it, resulting in a 3/4 inch gap between filters and meter, allowing extraneous light to come between them, throwing off the metering. So what I`ve thought about doing is just putting the filtering setup I`ll be using onto my digital SLR camera and using it to get the metering, then just use that. But I want to know how close the metering will translate onto the 4x5 camera. I`ve done this with my medium format camera and it worked quite well, but this is really my first time with a large format. What do you guys think? Oh ya, do shutter speeds just start doing the exact opposite once it hits 1 second? like 1s, 2s, 4s, 8s, 15s, 30s, 60s, 125s, 250s, 500s Thanks.
