I have recently bought the A-S Rotaslide for my Factum and am trying to work out the best way to mask the 6x9 ground glass for an IQ260. The main aim is to use the ground glass for critical focussing.
Initially I put a piece of acetate with the mask cut out under the small 'bars' that hold the glass in place. Two problems: the acetate wouldn't lie flat and then it started snowing when I was in the field and the acetate went all sticky.
It's been suggested to me that I should either mark the boundary of the mask on the glass with a permanent Stabilo marker or cut the mask from a sheet of lighting gel and and fix it to the glass with an adhesive.
Neither feel quite right and I wonder what solution others may have found ?
The holder for the ground glass on the newer Rotaslides doesn't rotate. I can always take it out and turn it 90 degress but the ideal solution would have the mask in both landscape and portrait shapes i.e. a cross/"plus sign" shape.
Any ideas or better solutions would be much appreciated.
