>>3444656Start with a Holga. There is a ridiculous amount of freedom that comes with such a simple system, because all the parts work independently.
It will teach you:
-focusing by estimating distance,
-what you can do with 2 shutter speeds (1/100 or as long as you hold down the shutter) and 1 aperture (f/11 because the aperture selector actually does nothing)
-to use flash besides just when it's dark
-which ISO/ASA film works in different amounts of light
-to appreciate unintended over/underexposure and the way it changes the mood of the picture, which you'll know how to
-what tripods are really for
