How to FIX Light Leaks and Frame Lines. Mamiya RB67 ProS - Light Seals Replacement Tutorial

In this video I show how to replace the deteriorated foam light seals in a Mamiya RB67 ProS . Older cameras often used foam light seals that fall apart at some point in time. If not replaced, it will eventually cause light leaks on film and ruin your photographs. Here I show how to replace all necessary light seals in Mamiya RB67 and share my approach on how to draw new vertical guide lines (frame lines) on the focusing screen. Enjoy and feel free to comment and share your knowledge!
