sup /p/, some shots from photography class today. I'm finally starting to get the hang of this shit. One question: how do I go about making pictures with long exposure times in daylight without them being way too bright?

Lower iso no?

Also ND filters.

I take it stop down means making the f-stop number larger...?

Right - larger f stop number means smaller aperture. The smaller the aperture, the more light is necessary to expose an image.

But if you end up stopped right down to f22 or so you can loose a lot of sharpness to difraction.

You'll lose some sharpness to diffraction - it's not going to be huge. If you need the small aperture for DOF, it's acceptable, but the lens won't be at its best at f/22 or smaller.

diffraction starts at f/10 on digital

Diffraction starts at different apertures on different lenses. The effects are more pronounced on digital.

Say a lens's sharpest aperture is f/5.6. Anything smaller, and you're losing sharpness to diffraction. Digital sensors are more sensitive to this than film,

fine, i'll rephrase

diffraction generally starts at f/10 on digital and f/16 on film

No, it'll start at the same place. The lens itself doesn't change. The effects will just be more pronounced with digital.

Incorrect. Diffraction failure is a function of the physical diameter of the hole through which light passes, so it is dependent on the focal length of the lens. A 20mm lens at f/16 and a 200mm lens at f/16 do not have the same diameter hole. While diffraction may be apparent at f/16 on the 20mm lens, it may not on the 200mm.

Im not saying it only turns up at f22, im saying that at f22 its going to be a big problem.
