Possible US Magazines:
“Photo Techniques” at
www.phototechmag.com has both a regularly published magazine and an occasional special. The current special is about "Essential Lighting Techniques". The one before that was Bruce Barnham's darkroom techniques. Bruce is on the Large Format Forum and works as part of the team of: Richard Ritter (camera builder & repair), Bruce, Ted Harris (Contributing Editor for View Camera Magazine).
ViewCamera.com has many articles on darkroom work and materials.
Since these magazines devote only a portion of their monthly output to darkrooms, is it possible that a book on the subject, geared to your present level and above might better seve your need? There have been many threads here and at the LF Forum on books devoted to darkroom work.
