You can choose which side do you want to shoot or take multiple exposure by the clever window switch that looks like an eye :) The 135TIM has another added feature is the 3 aperture settings, Sunny, Partly Cloudy and Cloudy.
Half frame shooting lets you double the amount of photos from a single roll. So a roll of film with 36 exposures will let you take 72 photos!!! :O
