The Ultimate Exposure Computer does not make erroneous assumptions. Exposure Value (EV 15), film speed (ISO 100), aperture (f/16) and shutter speed. Online photographic exposure calculator will calculate exposure value and table of aperture (f/stop) and shutter speeds for available light and difficult conditions.

In, there's this paragraph explaining f-stop and ISO equivalents: The two aperture settings are marked with the sunny and cloudy symbols which equate to f16 and f8.0 respectively (set via Waterford stops). Green day discography tpb file. Some additional exposure ‘control’ is available by loading different speed film. Lomo says the Spinner 360° settings are based on using ISO 400 film so you could get f11 and f5.6 with ISO 200 film or f22 and f11 with ISO 800 film. However, from what I understand about equivalents, this has gotten things backwards. It should be ISO 200 gives you f22 and f11 and ISO 800 gives you f11 and f5.6, because the slower film is equivalent to less light, therefore a smaller aperture gap (i.e., higher f-stop). Am I right here, or mistaken? If mistaken, could anyone offer a brief explanation?

You can't change the aperture by changing the ISO. There's an equivalence for exposure, but the wording of the review is confusing. Your understanding of how the equivalence works is exactly right.

The review may be trying to say what forsvairr notes in a comment — that (assuming constant shutter speed) to maintain the same exposure given by f/16 @ ISO 400 with ISO 800 film, you'd need to go down a stop to f/22. But since you can't with this camera, that really makes no sense. Or they could be trying to say that using faster film gives an exposure change like opening the aperture but getting the numbers wrong. (Not to mention mashing the idea of stop equivalence into 'aperture is exposure'.) I'd just ignore any parts of this review that include math.:).

The terminology in the review is pretty horrible but my understanding is: the camera in question has 2 aperture settings (sunny and cloudy) which provide an exposure value that is roughly equivalent to f/16 or f/8 with ISO 400 film (with 'somewhere between 1/125 and 1/250 second') What they then try to say is that you can adjust the exposure from there by using a different speed film. Essentially, this is what you have to work with: Shutter Speeds variable (estimated between 1/125 and 1/250) Aperture Two settings (estimated to be f/16 and f/8) Film Speed (ISO) uses standard 35mm film (100 - 800), but only limited by what is available to purchase.
