A weird little side effect of most people moving to digital cameras. Digital cameras have their upside. I took a photo development course in my twenties. I don't recall if I completed it. Probably not.
I have a serious medical condition and it puts one at risk for lung bleeds. Years ago, on an email list for the condition, someone who kept a health journal for their child was able to track their lung bleeds and determine they were being triggered by darkroom development work.
I've had several somewhat serious photographers in my life, one of whom set up a darkroom in their home. I'm glad to have digital cameras available for me because I can't safely do darkroom work. The chemicals are a danger to me.
But it's weird watching old style cameras become something of a dying art and it makes me think of that bricklayer who, late in life, found his skills in demand for doing historic restoration.
This looks like a really excellent resource for anyone interested in this hobby.
