no darkroom here, so that cancels some categories. For the rest very much DIY. All kinds of repairs, mainly + some home-grown oddities. Most of our cameras operate manually and none have auto-focus (errrrk). Basic rule: as little electronics as possible.
x Use an all-manual camera
x Develop your own negatives
x Make your own prints
x Mount your own prints
x Do your own repairs and damage [SIZE=2](More the latter than the former)[/SIZE]
x Mix up your own developer (as well as bleach, fix, hypo, & stabilizer)?
As well as:
x Matting, framing and glass cutting
x make my own easles and neg carriers
x Do my own plumbing
x Camera and darkroom equipment repairs (except on my Mamiya 6)
