New Schneider Platinum 1/2 Stop IR for CMOS Sensors

Bob, for which cameras do you mount the Schneider 750?

Ryan,

Thanks for the information so far. I assume you have the filter in house, so come on surely you can give us a better example of what it can do rather than just two shots of black cloth. I think most of us would like to see a shot of someone wearing a black jacket and clean skin tones etc. For a product that is going to cost $250 we need a little more convincing.

Have just noticed that the original post was uploaded February 2010, I thought this was new product information.

I must be going daft in my old age.

Having said that, I would have expected to see some better examples of what the filter can do - or was it never produced.

Gints.

The camera was the Silicon Imaging SI2K which at that time was running DVR1. It is now on DVR2 which seems to look better.

In Western Australia our light is hard and intense. On 0db gain the lenses as closed as they can be so ND filtering is necessary. Soft leaved deciduous foliage seems to sometimes aquire a grey tone on the undersides of leaves which is an un-natural look. It can be made to go away in post so it is not a biggie.

I intitally thought it might just be the penetration of light through the leaf is insufficient and when the full 11.5 stops of image is used there is not enough from the light through the leaf to register any green. Orange/yellow coloured laterite rock around here also does not reproduce faithfully on many cameras. I thought it was just something I had to live with until the IR debate started.

I bought the IR 750 by blind decision in the end. I could find nothing mentioned specific to the SI2K. I went with what was supposed to be good with the RED camera and that seems to have done the job.

I have yet to give it a shot on the EX1 but that may happen in the next two weeks as I am undertaking behind-the-scenes coverage for a local movie being shot on film.

A call to Schneider Optics revealed that these filters are in production , though it's a lengthy of a back-order situation with the larger square filters taking precedence over the 77mm screw-in filters. I've ordered one and will post some screen grabs.
