I shoot my DSLR like a box camera. Although it does change settings automatically I don't know it. My DSLR allows me to set my aperture on the lens which I like and then shutter is auto set along with the focus.
This week I'll go to an event and take flash shots: set aperture, let camera decide ambient light one under, have my Vivitar 2600-d flash (who knows when that was made) set on A2 auto. No thinking involved. I've done this with film AF bodies but I can't see the histogram.
You are right; life is easier for spray and pray (only not so much praying now).
