    Anybody ever done any shots using infrared filters? Considering getting one to play about with, but haven't used one previously. Any tips/hints/pitfalls to using same?

    pure infrared filters are completely opaque to the human eye, i think.
    if you're shooting infrared film, a red filter should see you fine.

    Fenster has shot great shots a little while back using a IR filter. Hopefully he will see this otherwise PM.

    Have used the IR film + red filters as said above, and I have read about a camera mod that enables digital cameras to take proper IR pics too. It does entail sending the camera away to be mod'ed though.

    And he does mean Fenster, it's not a spelling mistake :D

    Not exactly tied to the original question but fuji have just announced a new Bridge SLR that has Infra Red Sensitivity built in. It's called the IS1 and DP Review have a press release on it here: http://www.dpreview.com/news/0701/07010403fujifilmfinepixis1.asp

    Got these set of nags with IR film years ago, there's a good resource here

    Fenster acknowledges this thread and will reply again with photos upon return to his home.

    Absolutely amazing Fenster! I'm planning on getting big into ir photography now. Hopefully I'll be able to yeild results close to that after a while..

    trooney are you shooting film or digital? I started experimenting with digital IR last year and have had some results:

    Using a Hoya r72 and an ingenious yoke that I can strap onto the front of a digital ixus. Long exposures and noisy images for the most part, but a lot depends on the sensitivity of your digital camera to IR wavelengths.

    Of course if you're shooting film ...

    can't help you.

    :)

    The ingenious yoke is as you say "ingenious", love it.

    Not a great fan of IR must admit, but the last shot from Fenster is fab.

    Shooting IR is tricksy at best, and very much a case of hit or miss.


  • Registered Users, Registered Users 2 Posts: 16,624 ✭✭✭✭Fajitas!


    I think Fenster's #2 and #3 shots are probably the best examples of IR...Really love them.


  • Closed Accounts Posts: 858 ✭✭✭helios


    hey all, just saw some nice IR pics on flickr, plus Fenster's pics were killer... does it work just as well on digital with an IR filter? I can get that Hoya one relatively cheap on eBay and I was considering it...


  • Registered Users, Registered Users 2 Posts: 771 ✭✭✭Rojo


    I love Fenster's fire hydrant!




    That sounds so raunchy!! :-|

    I'd be shooting with dig.

    A quick test to tell if a dig camera will work with an IR filter is to view the IT transmitter of a teevee remote through the camera while pressing buttons on the remote. You should see the light of the IR flashing.
    Because the filters are so opaque I understood it to be a little 'hit and miss' using one of these filters. Bracketing is our friend.
    Can anybody explain the difference between the different IR filters that are available? Not the brands, but the different IT wavelenghts the filters come in.


  • Registered Users, Registered Users 2 Posts: 1,535 ✭✭✭bp_me


    While I dont know this for a fact, I would imagine you want a filter that works in the "near IR" range.

    My reasoning for this is that a camera is designed to capture the colour wavelengths the human eye can see and the IR snesitivity inherent in the devices design is by its nature of the shorter IR wavelengths.

    Now, a red laser is in or around 650nm wavelength, and if I remember correctly, the visible spectrum runs out around 700nm. So anything above this is going to give you the IR effect. The question becomes what wavelengths is your camera sensitive to.

    Found a link to a page about this:

    http://www.photocritic.org/category/camera-mods/

    This is a DIY version and as the article says, you'd have to hate your SLR to do it... :rolleyes:

    Good luck, I think.

    Here are a couple of links I found in the past - hope they are helpful to those wanting to give it a try.
