Hi there - may be the wrong place..... I have just bought a s/h Omega D5xl enlarger and need a bit of advice on how to use it. It came with a four blade masking device and a number of negative carriers. Do I use the masking device and the negative carriers together and, if so, which way up/down ? I bought an instruction manual and that really is a product guide rather than a manual.(posted 8291 days ago)TIA
