Fascinating rule, and it seems to work well, judging by your images. But because the focal length is part of the equation, it really restricts you with regard to the lens you can use. I mean, f/1.4 or f/2? This almost guarantees you'll be working with a normal lens. But let's say you have a fast 35mm or 85mm that meets these requirements. What shutter speed do you use? Well, if you have a modern camera such that you can select in-between shutter speeds, then that's okay, I guess, but what if you're shooting with a regular old film camera like your M2? 1/85 and 1/35 are very in-between speeds. And reciprocity won't work because the required apertures are likely faster than the lenses can handle.

I read of somebody's 'Dark 2 rule' - ISO400 film, aperture at 1.4 or 2.0 and shutter speed the reciprocal of focal length. So I wandered round the house last night with the M2, Neopan 400, Lux 50 @1.4, 1/60 sec. HC-110 and X1 scans:

I've never heard of this rule and don't see how it can really be right as the focal length wouldn't affect the amount of light available to get the shutter speed required. That's not to say nothing decent will come out, but I think the rule would need to include a fixed shutter speed rather than one that varies with focal length and even then, light levels vary greatly from one place to another.

In what I consider a reasonably well-lit indoor environment (either no window light & "normal" amount of artificial light or very limited window light) I can get well-exposed shots at ISO 1600, 1/60s and f/2 to f/2.8. The shutter speed limits me to 55mm or wider but that's not a problem as in that situation I'd be using a fast 35 or 50/55mm lens anyway. These were all shot in such situations on Tri-X at 1600.

I believe the point of the 'rule' is to simply maximise exposure while preventing shake from a slow shutter speed. Whether that will turn out to be enough light is something you find out when the negatives come off the reel!

Nice looking pushed Tri-X shots, Jonathan. I would have expected more visible grain at ISO 1600.

Great capture of a plane (Snowbird?) taking off. Did it take many tries?

Gosh. Does the pilot get bathroom breaks?

I was wondering how you did that with max 1/500 shutter.

Max 1/500 shutter is plenty fast enough for airshows. When I saw the photo, I knew it had to be a static display because drmoss shot it with a Rolleiflex. The air marshals at airshows don't let spectators get anywhere near that close to the aircraft when they're actually flying.

That's a Lockheed F-80, by the way. The US Air Force's first operational jet fighter.

Never been to an air show. Could you tell?
