Exposure comp in lieu of ISO adjustment

Long story short, I'm shooting 35mm Delta 3200 film in a Nikon F75. This camera does not have ISO settings, it goes by DX coding only. I keep hearing that I should shoot the 3200 Delta at 1600 speeds and have it pushed to 3200 speeds (for better contrast). Am I correct that I want to dial in -1 EV?

No. +1 EV. You want to overexpose a stop - simulating the use of a slower film.

So, for example, if using ISO 3200 and a scene meters correctly at 1/1000 and f/11, +1 EV is like 1/1000 at f/8 (or 1/500 at f/11), which is what your meter would give for an ISO 1600 film.
 
Thanks, it just seems "backwards" but your explanation makes sense.


I should have splurged for that F100...

Exposure with the F100 set to 1600 won't be any different than the N75 set to expose at +1, in fact may be worse, due to older exposure system in the F100.
 
I have both the N75 and F100. The F100 will remember a ISO correction when it is turned on again, however the N75 forgets it.

I have noticed this.

Are you talking about the metering system? The F100 uses spot for AI/AIS lenses, it cannot use matrix metering. It can use the matrix system for any other lenses (G/D/etc.) The F75 can use matrix metering with any type lenses. That's as far as I understand.

Curiously enough, the default metering mode is center-weighed for the F75, even though the much superior matrix meter is available.

No. The F75 doesn't have an AI tab so doesn't meter AI/AIS lenses at all.
Cameras that can matrix meter AI/AIS glass are FA, F4 and F6 only.

Didn't you forget F100?
 
You could also alter the DX coding on the film cartridge and then not have to mess with anything on the camera. In other words, put a small square of electrical tape on the second registration from the top left.

Here's a link to how it works and how to read and manipulate that. https://en.wikipedia.org/wiki/DX_encoding
