IR portraits

[adamadam]

I like IR pictures and IR pictures of people
I would like to see more IR pictures of people here

The problem is; with cameras like the 300D, it requires long exposure, so you have to make your subject stay still for that time whereas my cheap old "amconics" camera didn't need long exposures, you could even record video in IR For the filter, I used pieces of film which were developed, but unexposed - I'm not sure if this is correct, but it's the end of the negative where it's very dark, I stuck two together to make it block out more visible light, and then stuck it front of the lens.
I haven't used it for a while though, and trying to find the pictures, I think it's in my 2003 archives

Dig up your archive and show, it'll be interesting.

1 Films which were developed, but unexposed will be totally transparent. The very dark portion of the negative at the end is the exposed portion.

2 It you stick the dark portions together and use this as a filter, you are actually using these as neutral density filters, meaning all you achieved is to reduce the amount of light hitting the film! You are not filtering out the light rays and only allowing the infra-red portion to come through! So you won't get infra-red images.

oh! that sounds true Thanks student.
When doing remote-control test with this 'filter' on, only the light from the remote control shows, is that because the light from the remote control is more intense than the visible light? Similarly when using IR LEDs.

I thought it was though;

well, was a nice effect anyway

Haha! not quite sure how to explain that!

Let me try. I think some remote controls use infrared beams (others use radio frequency, I think!). Sometimes while developing, the antihalation layer might not be completely washed off, and a layer of red remains, blocking off the usual light but allowing some infra-red light through?

OK. don't laugh! Just some wild guess!

I get the same effect when I put my R72 infront

and I still can't find where I put those pictures ~ nothing amazing anyway, just a picture of me... hahaha, it made my black shirt come out white. funky~!

hi teerex, i like your IR photos very much. what camera/filters did you use?

[eawtan]

The transmission response of E6, unexposed but developed film as an IR filter can be found at : http://www.rit.edu/~andpph/text-infrared-filter.html

1 or 2 pcs of E6, unexposed but developed film can be successfully used as an IR filter. The only issue(s) are getting the E6 film large enough for your lens, and getting it absolutely flat.

Thanks cameraman,

I use the D70 with the Kit Lens for all my IR photos. IR filter used is the Hoya R72.

You interested in shooting IR? Which camera are you using? Come join us in our next IR outing if you can. The link to the outing is HERE

thx teerex. me currently using film camera. one eye on 20D the other on 350D. will join you soon.
