That's one of the things I'm trying to establish.

I've been shooting stage shows since the EX1 first came out. Despite the extra cost I think you'll find the 486 better suited to your needs. We're never shooting wide enough for the downside of the 486 to be a problem.

Hello Bob,
Tell me do leave the 486 on the camera all time and if you do any have you notice changes to colours etc when shooting outdoors.
Many Thanks

Just in case anyone doubted the EX3 has IR problems take a look at my Canon 1D Mkl 1V preview - top item on my home page - the T shirts are black to my eye but not to the Sony lens.

Warehouse: Sunlight
Bedroom: Tungsten
Liquor Store: Fluorescent

Graham,

I brought the screen grabs into Avid and tried correcting them. The bedroom scene is definitely a challenge b/c a lot of similar colors in the composition.

The warehouse was pretty straight forward. The matte did choose some other parts of the scene, but it didn't really change the rest of the image that much.

The liquor store looked good as it was, so I didn't mess with it.

Using a filter is definitely easier. But it does lose light, add a slight green bias (even with a new WB) and reduce red intensity, it seems that using one when needed would be optimal.

But I have to say, the bedroom scene was more difficult to correct than I would have thought.

Thanks for the examples.

I've had success with Colorista by using the power mask feature. Not ideal but saved my backside where one important interviewee had her black jacket turn brown.

The jacket is still not quite black, but any more tweaking and the other colours in the same area as I'd applied the mask started to look wrong.

Of course if the camera or the subject is moving things would get considerable more challenging.

Hey Peter thanks for trying that out. I also had some success with the outdoor scenes but like you said, the bedroom was a major challenge. I can't imagine how it could be done without rotoscoping.

I was able to get fairly decent results in most scenes with the video paused. That was achieved with some edge thinning and softening in FCP's 3-way color corrector and when played back, the imperfections of the limiter caused funny motion artifacts that were totally unacceptable.

We finally decided to just leave it as is. Client and fans are happy. I wonder how many people question the color changing clothes when casually watching the video. It aired on MTV India and other big networks out there so it was a shame that the blacks didn't come out like they should have.

I included that as a reference for what the black fabric should look like. As you know, fluorescents don't emit infrared light (or at least not in great quantities) so there was no problem there.
