What Are The Components Of Kirkland Paper Towels?

experiments with infrared

For a few days Pursuing the possibilities in the field of infrared photography. My first victim was an old, disused Nikon D100.
The first attempt was referring to how much the D100 IR to pass through at all, because sitting in front of the sensor a blocking filter which blocks light IR should be more or less. With the D100, it seems more likely to be more for less. To do this but to find out, I simply photographed once the IR remote control my TV with the button pressed. The IR light beam of the remote control is shown in the image clearly, the camera is for IR right receivers, see Image:


have As I previously involved have never used infrared photography, I also have an infrared filter. So what to do if you just going to want to do a few test pictures? It is of advantage if you are still in the "film school" is and has slide films in the archive. Often it was not a final order of the full slide film exposed, but you were immediately sent for development, because the customer is waiting on the slides. The unexposed end piece I was then sent with the mounted slides always. Mostly I've thrown it, but luckily I have found some of these end pieces again. These are for some "quick and dirty" tests is the one. Because: A unexposed but developed E6 film is black, does so little light in the visible spectrum between 400nm and 700nm by. But he lets through infrared light over 700nm.

To test this seemed to me an old Cokin filter holder handy. (Yes, I have sometimes blue course, Sepia course and what-I-white-over-Cokin filters and I bought it snapped tot ... which are felt 100 years ago) Anyway, I dug out the old filter holder and placed inside a filter. Behind the filter 2 strips clamped the developed but unexposed E6 film. Started before the whole ne 50mm 1.8 lens and individual test.

served as the test object me my stamp and before another piece of developed but unexposed E6 film. The result: Top image is normal, lower to the E6 film in front of the lens.

You can see nice, normal picture at the top of the plunger, the spring is hard to see. The blue plastic of the stamp, although transparent in the original form, the structure for the test images, however, fell by no light, so that this plastic seems very dark. In the lower recording with E6 film in front of the lens can see the feather detail. Also in the normal shooting, the slide film is black, in the recording with E6 film in front of the camera is the slide film transparent.
The next test I would like to make is with the Nikon D700 and high ISO. Let's see what happens.

And the monitor in the background is not the only, but the only "tube" which I still possess. And from that I use and still for good reason ... thought otherwise, he hangs on an old PC that is just for the paperwork.
