1 disposable camera ($12) + developing the disposable camera ($13) = 20 discernible photos (priceless)
There's something so satisfying about disposable cameras. That click! sound after you take a photo and the winding of the film until its taut. The need to ration your 27-shot camera across the course of 3 days, limiting you to roughly a photo an hour. But nothing beats the anticipation of receiving your photos weeks later in those paper envelopes, only to find out a third of your photos are just all-black because you didn't understand or forgot how to use the manual flash. Nostalgia is what the soft grainy quality of my glossy 4x6 photos feels like, and the imperfections of my TomorrowWorld photos is something no Instagram filter can replicate.
