How to Build a Darkroom for £100 or Less – Darkroom Technique Part 1 – by Sroyon Mukherjee – 35mmc

I’ve been shooting film since the late 90s; my father bought me a quirky little National 35 when I was thirteen. But I started darkroom printing just a year and a half ago, in autumn 2018. What took me so long? Two misconceptions, mainly – that it’s expensive, and that it’s difficult. In fact, it turns out that setting up a basic darkroom need not be expensive. In this, the first of a five-part series on printing black-and-white photographs in a darkroom, I want to illustrate just how cheap it can be – how, through a combination of eBay deals and some dubious hacks, I built a makeshift but fully-functional darkroom in a small flat for a grand total of £92.50… and how you can too (clickbaity but true!)
