One has to be in the mood.. inspired
I'll copy the little bit i mentioned in the chat thread.
One of the features for me 1st months in singapore.. was all the WWII sites.. especially Changi Prison Museum...
Photos on display included about 10 taken and developed by POW on hidden folding camera.. using film squares cut from Xray plates.. developed with homemade chemical concoctions. Photos later used as evidence in Japanese War crime trials.
I bought a book.. story plus copy of photos...
Changi Photographer... George Aspinall's Record of Captivity If you google I am sure some of the photos are online.
This was a "kid" who went to war with an interest in photography and a very early camera.. he did learn to develop his own photos by helping out at local photo shop in Changi (I have been to where that shop was).. one of his early work-details as POW was clearing out Singapore harbor warehouses for the Japs.. and he had sense to score some xray film which he cut into squares to fit camera (Single shot loaded in dark of night). He also scored some developing chemicals. If he took a photo he had to remove and develop himself.. and load another square at night for next days shot. Lucky the shots worked at all. Lucky he kept camera hidden through multiple searches. At the end the camera and photos were dropped/buried down a long-drop latrine.. but eventually recovered.
