Recently I was talking to someone in a pub, and mentioned that I engaged in film photography. They mentioned that they did not personally approve of film photography, as it contains animal products. This is not something I had previously put much thought into, despite generally agreeing that meat is not a particularly sustainable source of food. Whilst, after a bit of research, I’m mostly at peace with the fact that photographic emulsion uses an extremely small amount of gelatin – primarily as it is making use of a by-product which otherwise would have gone to waste, and in of itself isn’t a driver for meat production.
