wilfredo Posted June 13, 2007 Share #1 Â Posted June 13, 2007 Advertisement (gone after registration) I'm looking to purchase a multi media projector for slide shows, power point presentations, movies, etc. I need something for a space that seats 500. Any recommendations? In terms of a lap top, should I go PC or Mac? I just bought an IMAC, and I'm making the transition to the IMAC world, and starting to really like it.

replay Posted June 13, 2007 Share #2 Â Posted June 13, 2007 A couple of questions: Â How light is the room that the projector will be used? (more light more lumens needed) How many items will you need to project? (other than your mac) Â I also use a new power mac for my road shows.

graeme_clarke Posted June 13, 2007 Share #3 Â Posted June 13, 2007 I don't think the computer, PC or Mac matters - that's a personal choice for the way it handles the slide show software. Â I use a PC with pictures to exe - never used a Mac. Â The important item is the projector - If the room is only dimmed, rather than blacked out the intensity of colour, especially reds, will be a lot less than desirable! If the room is blacked out then the key question is "What size screen?" If its 12' x 10' you'll need more lumens than for 8'x6'. Remember your physics - the inverse square law applies! You'll find in blacked out halls that many of the higher power projectors will punch too much light through - which can wash out highlights and open up shadow detail compared to your computer screen or even moreso compared to prints. You can lower the output on many of them so a trial in the hall before you start is crucial. My advice is don't get a one that you cannot alter the output. Â The projector I use is out of my hands at the moment and I cannot remember its output. In any event its 3 years old now so you'll want to check the specs of the latest models. Â There are plenty around - perhaps you could try some? Â Hope this helps, Graeme Link to post Share on other sites More sharing options...
wilfredo Posted June 13, 2007 Author Share #4 Â Posted June 13, 2007 I guess I'm wondering how many lumins to go for. I can see using it in a small or large space, depending on need. Â Wilfredo+ Link to post Share on other sites More sharing options...
boilerdoc Posted June 14, 2007 Share #5 Â Posted June 14, 2007 Wilfredo: For a small dark room 1000 lumens is plenty. For a large not dim room you will need 2000. Also resolution should be 1080 for decent quality. More resolution the better picture but the price shoots up fast. The new Canon s60 (i think it is) is a super DP I've heard.

dist Posted June 14, 2007 Share #7 Â Posted June 14, 2007 Advertisement (gone after registration) You'll want to make best possible use of available display real estate. Many projectors nowadays are geared towards home cinema and hence use 16:9 displays. If you shoot 4:3, a projector like the Canon SX series (1400x1050 resolution, LCOS display which means no visible "flyscreen" mesh and, unlike many DLP projectors, no rainbow effect) is ideal. If you shoot 3:2 you're somewhere in between, meaning you won't use all available pixels with either 16:9 or 4:3 displays. Just some food for thought. I do know that the SX line of projectors is used a lot for audiovisual shows (I have one which I use for cinema though). Good value for money imho. YMMV.

ho_co Posted June 14, 2007 Share #8 Â Posted June 14, 2007 Wilfredo-- There was a pretty comprehensive article on the topic in LFI 4 May/June 2006, pp 30-37. Link to post Share on other sites More sharing options...
dfarkas Posted June 14, 2007 Share #9 Â Posted June 14, 2007 I use the Dell 5100MP, which I believe is 3000 lumens. I chose it for its resolution, which is 1400 x 1050. It can be had for less than $3K. Also, dont't forget that the image quality gets a whole lot better when you calibrate and profile a projector. I use the EyeOne XT, which has the ability to generate color profiles for projectors. Â Best of luck. Â David Link to post Share on other sites More sharing options...
