This is a known behavior with the EX1/EX3 cameras along with others (most notably the RED). It's called infrared contamination. Do a search in this forum and you'll see several detailed discussions.

On my first paying gig with my EX3, I shot a sit-down interview and the subject's very black suit got recorded as two very icky shades of brown.

The solution for me was the B+W / Schneider 486 UV-IR Cut filter 77mm Slim. (the 'Slim' is important)

Haven't seen the IR problem since (nor any vignetting that has been reported at the widest zoom).

Hope that helps. (but I know of no way of correcting the IR contaminated blacks in post, so I guess that doesn't help much with your current footage - others here may know better though)

I have not personally had this problem, I use mostly daylight lights. But have read a lot about this phenomenon.

I would say it is bound to happen, digital cameras like film are very different than our eyes.

I think this could easily be fixed in post, a secondary correction in Color.

Just use eye dropper to select by dragging across fabric and then fine tune in color sliders. Then adjust color in high, mid and dark etc. You could even turn the suit scarlet.

This cannot be easily fixed in post as the effect depends on the type of black fabric. To correct you need to mask and possibly track the offending fabrics and CC them.
I had this happen to me once, thankfully not on anything the client could complain about. Since then a 486 filter stays on the camera and the problem is gone.

The post I made earlier is a really easy way to mask and track and correct any specific hue, using a secondary CC room in Apple's Color. It is very fast and easy to do. I use that technique often to make a specific change in one color.

You can do digital makeup on problematic skin very easily in the FX room, using similar tracking and masking. It is fast easy and works very well.

Teal has always been a difficult color to capture, even on film.

Does anyone know where i can get this filter in the uk ?
