Ben,as promised this is my recommended Ir shooting technique.The Canon DSLR & lenses are not Ir compatable as the Nikons of earlier vintage.The D200 isn`t Ir friendly far too much noise. Shooting setup.... Shoot at least f8 to make allowance for focusing difference between Ir & non-Ir.Low contrast,low Iso to minimize noise, low or no sharpening,tripod,R72 filter & C-polarizer.Use -ev compensation to control the clouds.Take test shots to determine correct exposure and switch to MANUAL exposure mode.I focus at the beginning of the image and switch to Manual focusing because I normally takes a lot of shots of the same area. Work flows... This link is my work flow http://www.usefilm.com/Image.asp?ID=1285949 Another excellent one from Sam http://www.usefilm.com/Image.asp?ID=1295637 My Photoshop CS2 B&W work flow I normally do a 'Levels' tweak,then Channel Mixer with 'Monochrome' box check.Shadows/Hightlight,Exposure, Brightness/Contrast.For blurring Gaussian Blur to about 25 Fade.Noise remover. I manipulated your image and you are on the right track for a first try. Hope this helps. Take care Robbie Hope that helps.
Very good first attempt Ben but your clouds are blown out.Eperiment with -ev compensation to control the clouds. I shoot with a IR converted D70. Gotta run,will give you more tips later tonight. Take care Robbie
