Hi! So I bought a Holga b/c I thought it'd be fun to try and I've seen many great results from others. It's still sitting in the box it came in! =/ I need a lil' tutorial if anyone can help. What kind of tape to use for blocking light leaks? It's 120 film, right? Any specific types? Is it difficult to roll the film? How to handle it? I hear you have to count your own exposures?
