Unfortunately, a CT preset will not work by itself. You need to compensate each of the 3 channels differently, which only can be done balancing with AWB.

That wouldn't be much of a problem, except it's too easy to inadvertently knock the AWB push button during the shoot, and spoil the WB as the switch is not at the "preset" position.

I don't believe this will work because as far as I can see the filter affects each colour differently and it depends on the conditions.

I would also refrain from keeping the filter on all the time. I was using it for the first time in anger last week and ended up far from impressed. It cured the problem I had for the shots in question, but even after a WB certain colours took on a green tinge and the image lacked a certain "punch" which took some work with Colorista to restore.

The T1 should only be on the camera when you have a specific problem IMO. Its solved my black problem fantastically but not only did the image take on the aforementioned characteristics, the light loss in the situation I was in was annoying.

Piotr, is AWB different from ATW? If so, how does one AWB which compensates for each channel?

I recently got the T1 and notice a green cast, which is easily fixed in post.

Steve,

Very generally speaking: in ATW mode, your camera is *supposed* to track and adjust CT completely automatically for you (e.g. when following your subject, you are shooting inside with tungsten light and then you need to go outside for day light - and you cannot afford to stop shooting for taking manual WB). On some cameras this can actually work, but not on the EX cameras where it's pretty useless.

AWB is triggered manually by pressing the button while pointing the camera at what you want to appear as white (or shade of, hence a "white card" or "warm card").

I think this IR issue might not be specific to the Sony EX line. Last night I was watching the Chicken Buster episode of Dirty Jobs, and I noticed some of the dark blue/black uniform trousers had that reddish-brown tint. I was careful to note the shots where I saw it... all were from whatever shoulder-mounted HD cams the show is using. The trousers looked fine in the shots from the Z1Us.

Watch History channels Pawn Star. They all wear black T-shirts. When they cut from shot to shot the shirts keep changing color from black to red/brown.
I've been seeing this more and more on teevee

I did watch that last night and noticed the same thing.

The new filter, officially called the Platinum 1/2 Stop IR filter, will have front threads in all common threaded sizes that are deep enough to screw-in other filters but does not cause vignetting on the EX Series cameras.

We will begin shipping these in about 3 to 4 weeks at the latest.

Part number for 77mm size: 68-063077
List Price: $250.00 USD

You can order from any Schneider dealer that sponsors this site as a special order and it will become a regularly sold item in the future.

Thanks,

Ryan, will this filter have any issues with a reflective front surface like some of the other IR filters had? Is it an ordinary dye based filter?

Ryan- At $250, the Platinum filter is 3 times the price of the T1. What does the Platinum do the Tiffen doesn't?
Pete

This is my reservation, as well - for that price, I've got TWO T1s (77mm and 4x5.65").

Of course, thorough tests can still prove the Platinum 1/2 Stop IR filter is worth the price...

Ryan, any estimation for the 4x5.65" version?

T1 trade-in program?
 

Ryan, for those of us that bought the T1 solution and found the results disappointing, how about a trade-in program? I for one would be really reluctant to buy yet another filter that promises to address the IR problem only to find that it too has unwanted side effects...

I wouldn't count on a trade-in program, seeing as the T1 is made by Tiffen and this new filter is by Schneider.

I have a T1 and yes, it fixes the reddish-black problem but does so at the expense of everything looking green (as many have pointed out). It's easier to CC out the green than the red/blacks, but I would be willing to pay more for a solution that works cleaner...

Yes, after initially being pleased with the T1 I've now detected some green tinging on the fake tans of two of my subjects from the other week.

Rest of the image is correct, but the tans seem to just give a slight green tinge. Matt Davis (of this neighbourhood) tells me he's had problems with fake tans on camera without the IR issue. So I guess the T1 is just compounding that.

I'm now trying to dial this out but it does mean the rest of the image is going to be impacted.

I'd be interested in one of the new filters but given how long it took me to get a T1 I don't expect to see one for sale in the UK this side of July!
