Experimental portraits with an infra-red filter. F5, 4-5 second exposures, ISO 100.

Here is the second bunch of experimental photos from my recent shoot with Zebora. In these I've used an infra-red screw in filter to create some dramatic and ghostly monochrome shots (some of which I've tinted slightly in post-processing to add a little more depth to them.
The exposures were long at 4 or five seconds each and I kept the ISO low at 100 to keep the noise on the pictures to a minimum (but no matter what you do though, Infra-red shots always have a nice graininess to them). The poses where Debz stood up were subject to some blurring as she made small movements while maintaining her pose, however I do quite enjoy the ghostly effect this creates when coupled with the light burst from the sun behind her. Of course when she was laid down this problem was eliminated and the result was some beautifully marble-looking skin when converted to monochrome.
I'm not sure what caused the light streak in a couple of the shots, whether it was some light lens refraction or an insect flying through the shot, but it isn't unpleasant and I think adds something dynamic to the pictures. The only things I'd maybe change next time are; I'd make use of a reflector to just bounce some light back at the model to give her a more uniform skin tone in the shots where the sun is behind here... and also maybe invest in some kind of posing aid as utilised by Victorian photographers who regularly dealt in long exposure portraits.
