shinier fabrics seem to have more Red problem than others, but all fabrics are different.

Thanks again Brian,
I did a school concert a few lights ago, in fact I have to record it 3 times in total. The first night I didn't have my filter on, I thought, just wait and see what happens first, it wasn't long till I discovered I needed the filter.

I Think you said Brian not to leave it on at all times, only when needed.

Thanks.

Did I read somewhere that reds can give bother too.

Yes that's what I did say a few weeks ago but I have changed my view. Due to the fact that the green vignette is hardly noticeable in wedding videography, I decided that if there is a possibility that I will run into this IR problem, I put on the filter immediately. I believe that people are more readily to notice a brownish suit (which should have been black) than a slight green vignette. Having said this, none have complained so far about the brown tint when I did not have the filter. But out of the 2 problems I prefer a black suit with a slight green vignette on wide shots only.

Brian, Have you tried to color correct the green vignette out?

Leonard, I didn't try hard enough. I use Premiere CS3 and I didn't find a quick way to do it and I did not bother to delve in further. If maybe someone can enlighten me......I'll appreciate it greatly!

I've realised that when one views the edited video on a 40 inch or larger TV, the eyes would focus in the middle of the screen and hence the green vignette at the edges is not so prominent. I do not know whether others would agree on this.

Has anyone tried tricking the white balence with a 1/3 green gell in front of lens to balance the green out, or is it just too subtle.

The tint isn't uniform, being a function of incident angle through the filter; increases from zero on axis to greater towards edges. Noticeable on wide angle. Can be corrected only in post, but since it is a function of lens focal length then correction isn't too painful.

Jason ,
The 1st prototype Tiffen Filter (still under development) is a uniform light green and balancing under that tint does work. As Serena explained the 486 is a green vignette green so it is not so simple.

Today I received the filter 486, we tested the EX1 has a tenta vignetare green but the picture obtained is much more true to color. Is visible to outside shooting, but a ok:
Maybe to show something from tiffen, which is currently the best solution .. my opinion :-)

If you have Tiffen's ear on this, they should consider making replacement filter sets for the EX3 ND filter wheel, or even a complete filter wheel assembly to replace the stock one. That would be the perfect solution. Replacing the stock filter wheel in the EX3 is a 10 minute job with a small screw driver. I believe it is even possible to replace the filters in the stock filter wheel with a bit of careful persuasion. One of these ideas would be the perfect solution and make using the EX3 an almost carefree thing. I have no idea how hard it would be to do this for the EX1.

I'll second this idea. I really don't want to add a 4X4 or bigger filter on a matte box nor a 77 screw in if I don't have to. I also have the W/A lens so a filter for that will be even bigger and more $$$.

Tiffen is still working on development of the filter itself. Its probably premature to ask for them to create replacements for internal Sony parts and there may be legal issues - I don't know.
It would probably depend on whether they end up designing a filter that appears colorless. If it remains green then it would not work as an internal filter.

I think Sony may be working on this issue as well now.

BTW balancing through a green filter didn't work for me except through the Tiffen prototype.

I have just read through most of the posts on this thread.

Yesterday I shot a stage production of Grease using the EX3, with a Canon XH A1 as a second camera. The intention was to mix and match the two in post production. However, the IR contamination on the Sony has rendered the clips useless. The Canon clips are perfect. I am bitterly disappointed with the Sony footage and will have to go back for a re-shoot on Friday. This is the first re-shoot that I have done in my 38 years as a photographer.

For what it is worth, my opinion is that the Sony camera with the IR problem is not fit for purpose. I don't see why users should be looking to third party filters to correct a problem which should not be present. I am today writing to Sony to ask them to provide a solution, the camera as it stands is fundamentally flawed. I would urge other owners to also write to Sony.

I take back what I said in my earlier post, it is now a real issue. This problem will be rectified when I go back and do my re-shoot using a Canon XH A1.

I am very, very angry
