    Infrared Look

    I seem to remember from the dark pit where my brain should be that using a Polarizing filter and Red filter together with a standard black and white film produces an infrared look.

    Does anyone remember anything like this or have experince of trying it?

    Red and Polariser together will give you the dramatic skies associated with infra red when there are white clouds in a blue sky. From memory I think you need to allow about 5 stops in compensation for the filters. You can further increase the contrast by under exposing and increasing development which will probably increase the grain.

    Thank you Les I'm in your debt once again. I'll give it a try as soon as we get some good light and a sky full of clouds which could be anytime with the weather conditions here at the moment.

    I've used the combination as an emergency neutral density set and have never notice any infrared enharncement. So I think the short answer to this is a simple no!
    As Les says the use of these two filters together will dramatically darken blue skys, but they will not effect green in the same way that infrared film does.

    Dramatic contrast yes, but I canot visualise the 'bleaching' effect on the greens.

    It's "kinda" an infrared effect but it depends on the light. To me, it's more of an interesting night-time effect that can be done at noon.

    Really depends on what you're shooting -- skies, foliage, people... To test, shoot some bracketed color frames with the polarizer, drop them into photoshop (or similar) and examine the individual RGB color layers. Do any of them look sort of like what you want for this subject? Then using that as a guide choose an appropriate filter and tweak the development is whichever direction you feel would be most appropriate (for an IRE look, go grainy and contrasty). Of course, by the time you're done testing you might have had time to scare-up some proper IR film

    Bjorke, discribes how I've created faux B&W IR effects from digital RGB files.

    One note on the red/polarizer combo.In my experience at least the polarizing effect with a wide lens is not consistent over the whole sky so the sky may not be uniformly black.Of course alot has to do with the position of the sun-usually at 90 degrees is best.

    Many thanks for the additional advice everyone. Les did say the combo should give me "the dramatic skies associated with infra red when there are white clouds in a blue sky" and not mention foliage btw Since I made the posting we've had nothing but flat light around here but when I have the conditions I'll give it a try and see what happens. Might even pick up a couple of real IR when I have the change as Bjorke suggested

    I'm trying to stay away from PS as much as possible which is why my neg scanner is up for sale in the other forum (shameless plug warning - any reasonable offers considered btw folks ). From now on it's flatbed of my wet prints only to post up here and to finally get around to updating my tatty site LOL
