I don't have f/32 on my camera...how do I make an equivalent for the same exposure?

Question

I'm trying to get the same exposure as f/32 what would be a good way to do that?
thanks.

Answer 1

First, what is the smallest aperture on your lens? (The diaphragm that controls the f-stops is in the lens, not the camera).

Second, what are you photographing that needs such a small opening? Lenses provide the best images at somewhere between f5.6 and f11. Above and below those values there is some image degradation. The Depth of Field from f22 to f32 (following the progression of f-stops, f8, f11, f16, f22, f32) will be minuscule at best.

Third, if your last f-stop is f22 just use -1 EV which is minus one stop and equivalent to f32. If its f16 use -2 EV.

Answer 2

The difference between f/22 and f/32 is one half stop, so to get the same exposure with f/22 using a shutter speed for a half stop smaller aperture just use a .6 ND and +1 EV (in a half stop increment) exposure compensation.

I'm not an expert (for all the pro's itching to say I'm wrong), but that's as close as I can figure it. I could be wrong, but just play around with the settings. The cool thing about digital is it affords you the ability to spend a few minutes bracketing your exposures until you get the right one.

Good luck.

Answer 3

You could close down to your smallest aperture, then stack on some ND filters/polarizers to cut down the light to an equivalent, use the slowest ISO film or camera. However, you won't have the same depth of field characteristics.

You'll have to do some math and figure out how many stops there are between the smallest aperture and f/32.

Answer 4

When you're focusing, there is a focal point call infinity, it looks like a sideways 8. When you hit this point everything in the background will be in focus. If you have a small aperture like f/22, then try focusing somewhere in the middle of your shot. If your shot has infinity in focus then then entire background will be in focus. And since you're using a small aperture and focusing in the middle of your shot, then your foreground will be in focus too.

If you don't understand that then just add a comment to my answer and I'll try to clearify.

Answer 5

F64

Answer 6

Neutral density filter.
