Let's preface this by letting you all know (which you'll soon figure out) that I'm terrible with numbers.

I've been loosely trying to figure this out for a while, but thought I would ask on here, as I've had good luck before. Now, let's see if I can explain this properly...

I'm wanting to shoot one of my lenses in the F2.5- F/4 range on bright days (summer is actually here, apparently). Normally, this isn't my bag, but I'd like to give it a shot.

The problem I have (being pretty inexperienced with all the calculations...and math in general... and LF... and...) is figuring out how to compensate with my filters with the limited shutter speeds of my lenses (highest being 1/1000 on my speed graphic , and lowest being 1/400 on my Rodenstock).

I tried to experiment on my digital camera, but reducing the shutter speed according to full stop increments left things under-exposed. I'm sure I'm doing something wrong.

Ok, I guess my question is this (if you've made it this far)...

Example:

-Meter reads at 1/4000 at F/2.5

-I want to keep the aperture at F/2.5 (Don't judge me)

-My highest available shutter speed is 1/1000

-I have a 10stop filter and a 6 stop filter available to me

-What the heck do I do?


Did that even make sense?
