I've been processing film since early 80's, and I did it for a living in NYC back in late 80's early 90's using baskets, 18 rolls of 120's, countless number of 35mm in those tanks, "inspection", jobo...man I processed more film there that I've done on my own stuff. Back then, and even now, I stood doing these. My boss even made a nice platform me to stand on, it was nice and cushiony

Today, I'm testing out long dev times in my kitchen. And it dawned on me "why don't you sit down for these 20 minute long dev times YOU IDIOT".

And I realized, all these years, I've always stood up processing film. How did I go so long without sitting down????
