DVD to try 'rainbow' effect...

[Sniper]

Hi,

Are there any particular movie sence's I should make sure to try on a DLP before purchasing! Basically I'm looking for something which will test to the max the capability of a projector with regards the 'rainbow' effect and also dark colour gradation.

Cheers!

You're looking for any scene with sharp, bright highlights against a dark background .. take the prolog to FoTR for example. The battle at the foot of Mount Doom, the shiny armour and weapons in the foreground against the dark brown gloom is a good starting point .. also, the closeup of the ring spinning and rolling in slow motion as it's thrown up in the air against the background of flames is also a good one to see rainbows where the ring is spinning.

Watch the scene normally and see if you notice anything. If not, or you're not sure, re-play and as you're watching that flick your eyes left and right but keep concentrating on the shiny highlights, that should induce worst-case rainbows.

This was my first introduction to rainbows and IMX a good indication of how I was affected generally. I see them but not badly and not so they distract me, the more extreme reactions people get like headaches and eye strain is more to do with watching DLPs per se rather than the direct effects of rainbows.

Another technique is to set subtitles on, and then see the effect (if you do) while reading them. Especially when the image underneath is dark.

For some reason Nigel I don't see rainbows with subtitles nearly so clearly as with 'in film' material, wonder if it's to do with the way subtitles are rendered on my projector, the Z200E is the only DLP I've had any long experience with .. I trialled an HT1000 using FoTR and that was enough to dissuade me in those days.

For me, if they exist on a given projector at all, then I cannot miss them reading subtitles.

Hmmm .. I won't try looking for them.

I used Se7en to test mine...although probably the best test I found was the opening shots in Azumi with a flock of crows flying against a blue sky.

Take any black and white film and then watch it with the subtitles on.

I've read Gladiator (the fight scenes with the swishing swords) is a good disc to test for rainbows.

I thought I didn't see rainbows untill I watched Blade1 and 2 on my friends Infocus 5700 after setting it up with my Avia disc. Yikes !!! All those high contrast action scenes left me feeling sick. His wife could see them too but my mate swears he couldn't. No DLP for me, which is a pity because I fancied the new Mitsubishi HC900. I'll still try and demo one though.
Cheers, Rob.

Anything BLACK AND WHITE can be used, with great contrast too.
In Star Wars I see rainbows in space batles.

Try spiderman in the begining part of the film.

A very knowledgable av fanatic on these forums told me this...

Seeing the rainbows is very much a state of mind (now thats not to say they aren't there) but try relaxing on your demo... a little yoga perhaps or a bottle of white. When you are stressed the rainbows are more prominent. When you are completely relaxed they seem to disappear. Try it!

Question. When i watch CGI movies I dont see one rainbow, not one. Why is this?

PS. Pirates of the Carribean had quite a few rainbows all the way through so a couple of weeks later I had 2 bottles of white and low and behold I hardly saw any!! Mind you i didn't make it to the end of the film either

Too many bottles leads to a "screen doubling" effect I hvae found

hi, i dont have a projector myself but im planning on getting one soon (most probably the epson tw10 as ive seen a cracking deal for it, lcd projector btw), you guys are talking about rainbows. how bad are rainbows when you see them on any projector whther itd be a dlp or lcd model. i havent really seen any live demos of projectors as i dont need to until i have the money to actually buy one, but are they bad? are they just light colours of rainbows or do they kind of like show up enough to ruin the scene of the film?
