Do I still use film? YES
Do I develop myself? YES
Advantages/Disadvantages? I don't think in terms of advantages/disadvantages. I use the format that gives me the result I'm after.
Do I use both? YES. I use film for B&W, digital for color
Scan negs? YES but not always. I use scanning as a tool to explore possibilities in darkroom
Mistake? NO. I don't believe in unintentional success. I plan and try to achieve my vision. Anything else is a failure in my own view.
Worse/Better? Again, I don't think in those terms. I love B&W and film gives me the feel and the results I'm after. For color, digital works for me.
