Okay I just purchased my hc9000d and I want to do a CIH zoom method "for now" I have a 110" 2:35 diagonal stewart firehawk g3 screen. The projector has a 1.8x zoom. Where is the optimum throw distance for this setup? I am new to CIH and I could use some advice!!
Technically you could use it anywhere that still gives you 1.33x zoom in the range. You will have to still lens shift the image as well for each AR change. Personally I would still use it in a long throw as you get better CR this way.
