I've been doing a little reading on infrared photography and there seems to be a bit of a grey area on what's the better filter to use. i've got £200 spare to spend, but i have both 67 and 77mm lenses to cater for. Any advice would be much appreciated. Bring on the frosty weather!!!

You could buy a 77mm filter and a stepping ring. The R72 is as good as any. It's very deep red and blocks all visible light. You can buy the filter in gel form or glass. The gel would fit into a Cokin gel holder for sue on their filter system, but it's easy to get marked and if you accidentally kink it you end up with reflective hot spots. Glass is the better choice and will easily fall within your budget.


Quote: not sure about digital, as I think you need to modify the camera?

No need to modify the camera, but some digital cameras work better than others. The result will be a very red photo that needs converting using your image editing program.
A better option would be to have a camera converted to digital. Buy a second body off eBay or our classified section and send it of to be converted. The IR filter is fixed over the sensor. It means you don't have long exposures, the focus shift has been taken care of at the sensor area, and there's no filter on the lens.
