Which explains why my exterior shots have been over exposed recently.
That lump behind the camera has been leaving the f stop wide open from
the interior shots.

The conclusion that my brain is dead, or just my camera? Sometimes
I wonder...

Yes, auto mode is about all I use. Laziness, mostly.

Except some of the foam, but I was expecting that.

I would have taken it over to Photosphere Saturday, but they're only open
Monday through Friday. I'd rather drive halfway across town than mail it
halfway across the country. And Photosphere has almost as good a reputation
as Camtech. I guess I'll be back to using my OM1, like Lee Hawkins.
