Analog film photography and cameras

afaik, slide is more sensitive to metering so you gotta get it right. If you're using flash for the first time, perhaps it's better to use a more forgiving film?

Slide film is much less forgiving with incorrect exposure, which is difficult to deal with when you're working quickly with different lighting conditions. Also, the different light sources will give you colour cast problems with slide.

Aha, OK, thanks all - Shall perhaps rethink my strategy :)
