    Oh and Ratty, what I did to meter with that is use my old Sekonic Deluxe incident meter, went to the sign on the left (you can't see it, but you can see the reflection if it on the ground in the 3rd image) and metered for that, leaving about a 6 foot distance from the light source, I assumed the two signs being similar would give similar results (and I couldn't reach the other "merit canteen" sign words, anyway I wanted them slightly less than fully blown out, and the interior to have some light from the inside, which is why I chose 6 feet from the light source, it seemed to be about the same amount of light as what would be inside the restaurant.... This was mostly just experience with metering this kind of scene, I certainly wouldn't have trusted my internal meter to this, I always carry my incident meter or spot meter when shooting low light.

    This was probably f/3.5 @ 1/30 or 1/15 with my yashika44LM 127 film (46mm re-rolled ilford special run).

    From my PERSONAL experience, HP5+ pushes almost better than D3200 and is finer grained. Also, if you rate 3200 film (really 1000 speed) at 1600, the film will be VERY low in contrast, almost too much for most people, giving a very flat image.

    PLUS D3200 isn't available in all formats, so it's nice to be able to utilize HP5+ for many different uses, it will also certainly be around longer than D3200... And fogs less... Is cheaper... Etc.

    Plus I think the OP just wanted to see if it would work.

    That depends on how you expose and develop it.

    We will have to agree to disagree... I'm not getting into a pissing match over something obvious, a 400 speed film like HP5+ has normal, if not almost less contrast shot at 400 than "average" contrast, so shot and developed at 1600 would have a lot more contrast being 2 stops under exposed and pushed...

    If you take the same equation, with D3200 that's truly 1000 in speed, but is designed to give "normal" contrast at 3200, if shot and developed at only 1600, it will have a lower contrast than normal... Being shot only 1/2 a stop faster than it's speed....

    So given those factors, HP5+ will always have more contrast than D3200 if both shot at the same EI and developed to the same EI...

    The final contrast of your negative is going to be mostly under your control. Sure, the under exposure will lessen shadow detail, but after that it's all about how long you develop your film. So a D3200 neg shot at EI1600 can still have practically any contrast you want.

    I am having difficulties with this part of your reply in terms of working out exactly what you mean. Can you help me here?

    Thanks

    HP5+ is lower in contrast shot at box speed than other 400 speed films shot at box speed.

    Sorry, Stone, but that doesn't compute. If your negative contrast is low you develop the film longer. Then your contrast isn't low anymore.

    I'm talking standard dev times according to manufacturer...

    yes you can adjust that to adjust contrast (as well as temp and dilution, other) I'm talking standard times. the films natural "habits" HP5+ is designed to be pushed, so it's designed to be slightly lower in contrast at box speed with manufacturer given times so as you push it, it will have normal contrast, this is true to an even higher degree with D3200, so it will have a lower contrast at 1600 than HP5+ at 1600.

    People don't like to think of it as PUSHING but even zone system adjustments for n1+\- etc, you're pushing or pulling, which adjusts contrast... They just like to think of it as a different thing, but it's not. (My opinion).

    So, lets see the densitometer plot.
