I know exactly where you are coming from. It hurts me to charge, but being retired, I have spent an arm and a leg on my first love! The honorarium to me won't even cover the travel for my wife and for me. I woulnd't go without her afer 40 years together.
I feel so sad, I can never fully express it here. And, things may come to what you allude to in B&W photography. Maybe, color as well. IDK.
Your little addendum also strikes a chord with me, having been in it since I was 12. I reemember my mother helping me control temperature for my first E1 Ektachrome process. It brings back memories. I wish you could be there. I would love to meet you.
All my best wishes for you.
