Obviously, there are huge differences in the media (film vs. sensor), but more experience shooting is always better. There are some important aspects of learning to shoot film. IMHO, i want to get the highest yield (more "good" pictures) from my picture-taking experience, so i want to think about film from the cost perspective and the opportunity perspective. It costs money to process film. There isn't going to be an opportunity to review the shot. You have to make sure it's good by doing the "preprosessing" with your eye, brain and camera.

So, choose and lock in the ISO - no "Auto-ISO" mumbo-jumbo. With film, because of differences in processing you really only get one ISO choice per roll (the standard ISO, or maybe push one or two stops), and you'll shoot the entire roll at that ISO. Shooting digital, you can choose the ISO per shot - my point is don't let the camera do this for you.

Choose the camera mode. Aperture priority? Shutter Priority? "full auto"? Manual? Ensure the exposure is right, either with a meter or using the camera's built in meter. no more "HI" for the shutter speed in the display when you're in aperture priority mode.

Slow down. Think. Compose carefully. Make it feel like taking this picture might be a once-in-a-lifetime opportunity (even if it is the Eiffel Tower).

Focus carefully, or verify that AF did the "right thing". Do you want to change the AF point? Maybe something on the left side of the picture should have the AF point? Preview your depth of field, if necessary - you might not have to preview the DOF if you have a good feel for the subject distance and your lens's behavior.

i guess even if you use a digital camera and pretend you're shooting film, you'll improve your technique by trying to live with the restrictions (and cost) of film.

Work on taking the same number of pictures as you do now, and try to get a better yield. Digital or film, i think that's a good goal as a photographer.
