- Ye old faithful Kodak carousel - cheap, slides are easy to make, completely controllable via RS232 (show control is SCS which can look after that) but only 1300 lumens.
- A bank of Selecon Pacifics
I've experimented with a bog-standard desktop video projector of ~1400 lumens projecting on to black with a similar image size - the brightness is just about workable but having not tried to project on to gauze before, I don't know just how much dimmer it's going to end up. Any advice on projecting on to gauze also welcome - I imagine the nearer perpendicular the better? The venue is continuous raked seating (no convenient circle front) so it's either the back wall or furthest LX bridge.
Is there anything else out there that can project from slides or acetate that sits somewhere between a slide projector and a PIGI in terms of brightness and cost? Any other budget options?
Throw is ~26m for an image diagonal of ~5m. 17m is also possible but the angle is somewhat steeper.
