Depending on what you want to get from the image, it could be a simple as converting it to grayscale and adjusting the highlights and midtones.
This would probably emphasize the pixelation in the sky, but a blur brush could take care of that. |

Hi,
First of all I must say I haven't a clue about IR beyond having seen sample pics, Just thought I'd have a go at this, I love a challenge, and freely admit I had no idea how to start, and what I have done is very experimental, and far from perfect IMO. See what you think, is the attachment something like what you're wanting, to me it is possible, someone with greater skills may help more. ... Jack |

It really looks as if your filter is not so much 'infra' as just Red.
You could try it with your camera set to B&W to see what happens. |

I know that some cameras (especially some web-cameras) have an IR filter on the sensor or on the lens in an effort to remove IR from the captured image (much like a UV-0 filter).
If you remove this "filter" and replace it with a scrap of exposed film, you can effectively create a camera that can only capture IR (as a piece of exposed film will filter out all visible light. So, two things. 1) Depending on your goal, there may be inexpensive ways of building yourself a little IR rig 2) Depending on the camera you're using, the IR might be filtered out already, regardless of what filter you add to the front of the lens. Just a couple thoughts ![]() Quote:

Conor is correct about the IR blocking filter on most camera sensors. Most all consumer cameras have them now, for a couple reasons. The photographic reason is to prevent IR from interfering with the exposure metering. The other reason is that some people used to use the cameras without the blocking filters to take 'x-ray' type photos of people (mostly women) seeming to show their undergarments, or lack of same.
Most DSLRs allow some IR through the filters, but if you want to take true IR pictures, there is very little of that light that reaches the sensor, and you end up with long exposure times. (unless the camera is modified to remove the blocking filter) |
