First, there are two very important notes for Holga shooting:
1. Take off the lens cap! It’s easy to forget, but „capped” Holga photos are completely black and generally not cool.
2. The advance wheel of the Holga is not automatic. You can click the shutter button and expose the same photo frame as many times as you want. This is wonderful if you want to take multiple exposures (more on that later), but not so nice if you intend to only take a single exposure. Remember this!
