What base were you at in charge of the photo lab???

I've been to to several photography schools back in the 1950s from military to NYI and I found they helped me a lot .I had my own lab back in the 1960s and photography is always changing. You need a good basic understanding of how the physics in photography work. NYI is the best in my opinion. Last time I heard it was only $1100.00 and well worth it and it can all be done on line..
