Oh Charles, you hit an other one out of the park here. I continue to be amazed at your depth of technical knowledge.

My own very right brain approach is completely related to my film experience. My ISO is always set to 400. I never use a tripod, unless I'm making self portraits.

And yes, the JPEG's are just fine for illustrating my stories here, after editing with Snapseed. I've become lazy in my old age!

You are doing new photogs a great service by explaining how digital photography truly works.

And thanks for your kind mention. It is much appreciated, my friend. Cheers to you.
