Hi James,

I have used a hoya infrared filtre RM-72 with my D300. Its works great. You will need a tridpod as exposures of around 10 to 30 seconds are required and you will need to bracket the focusing because infrared focus at a different wave length. So set the camera to manual set the shutter speed to 10 seconds to begin with, set aperture to f8 and set the focus to manual. Now what I do is focus on infinite and just edge it focus ring back a little. Fire the shutter and judge the outcome and adjust the exposure from their. once you have teh exposure right you can set it and forget it while you alter the focus till you get it sharp.

heres an example

Thanks Jeremy for sharing. Did you take the picture at a bright daylight at the jetty?
Do you still need to post edit with Photoshop later, let us take your photo as an example here for discussion. Weather in Kuala Lumpur has been gloomy, and rainy...will try that out soon. Thanks

Oh yes post processing is a must. the results of the steps above will give you a very magenta toned image, you can convert it to black & white with the channel mixer in PS or you can use the false colour action found towards the bottom of this page which works great.

The day wasnt overly bright it was a winters day in Melbourne australia so it was cold and overcast which is what brought out the clouds a little.

Good luck

Here's a link to an older site, but a lot of the information on here helped me when I first started taking IR pictures. Hope it helps
