For a long time, I Pooh-poohed the digital … until I bought my first digital camera. There was a specific reason I bought a camera of course (no longer in production): infrared photography.

One explanation is necessary. In the Cleveland area there is (was?) A wedding photographer who is famous for her wedding formals infrared. At the time I had him as a photographer of weddings, and I thought I could do the same. I met a photographer for studio recording, and Iwas not satisfied with the technical details, such as photos were taken in infrared. What would they do to you is a camera loaded with infrared film roll and tell the whole bracket. Yes, it is acceptable out requests, but stitched to me that there must be a scientific way to create usable shots … There are, reading (I then get to digital). Kodak, in their guide data that accompanies the film (Infrared Film) says you can with a light meter to determine exposure toInfrared … this is not right … Yes you can! However, (fine), you can not use a light meter in the usual way.

I used a Gossen Luna Pro, took a # 29 (footnote 29, not 25), gelatin filter and a piece of tape in front of the sensor. I think you can set the ASA where you want, but I have 400 EV, and took readings. Then I did some extensive testing (it is essential that you take notes). Kodak's Guide as a starter I had 6 brackets shots, I got exposurethe best preserved as a table from my notes. This is how my "scientific method works: Take a meter reading to use as shutter speed and aperture value of the table … it works very well (a fine point, you can not equal exposure values, if the table said 1 / 60 at f / 8, that is). Now that I have positive measure exposure, I was out to conquer the world.

Now the digital … I knew that digital cameras are able to do IR, I have more research. Currently, the best cameraThis was the Sony 707 (Cypershot) … I have one. The CCD in any digital camera in the world is sensitive to infrared and CCD is generally coated with a film that blocks light. Sony, however, has a filter that can be removed (flips a switch the camera). I used a filter "black (the name is because this filter does not transmit visible light).

Oh … my thesis on the tape … ! Ignore If this is scientific research with a 4×5, so the digitalenormously cheaper than film, film is redundant (one of the subtleties that can use a black filter can not be seen by a camera, you can use a digital camera).

The combination of black filter and a digital camera allows overlooked advantage. From a scientific perspective, it is very useful, the ability infrared image with the image of visible light (such as my album compared to Google) have. Everything you need to do, the camera on a tripod to shoot, haveImage with the filter on, and one with it off.
