russell_carey1 Posted November 23, 2004 Share Posted November 23, 2004 Can anyone point me in the direction of a good digital b+w infra red technique? CheersRussell Link to comment Share on other sites More sharing options...
beauh44 Posted November 23, 2004 Share Posted November 23, 2004 Hi Russel, I'm not sure if you want to do your infrared in Photoshop or in-camera. Not all digital cameras are created equal for doing infrared. They Sony Cybershot f-7X7 or 828 (I think) have a built-in "nightshot" mode that works well. Finally, you can duplicate infrared relatively easily in Photoshop. I Googled "Infrared Photoshop" and got a bunch of hits; here's a couple of them: http://www.fotofects.com/tutorials/photoshop/photographic_effects/infrared/index.htm http://www.nickgallery.com/web_pages/technical%207.htm Good luck!

jack paradise Posted November 23, 2004 Share Posted November 23, 2004 For those color images you have already taken, you can apply these channel mixer numbers in Photoshop: Red:140, Green 160, Blue -200 Sometimes it works, sometimes less, depends on the image.

paul_sokal___dallas__tx Posted November 23, 2004 Share Posted November 23, 2004 You can test your camera for IR sensitivity easily by shining your TV remote at it and taking a picture. If there is a bright spot of light then your chip is IR sensitive. Then it's only a matter of a filter. I'm using a Hoya R72 (which I think is equivalent to a Wratten 89B) on a D-70. It's been so cool and rainy here since I got the filter, I've only had limited experience, but it does indeed work. I take the image grey-scale in PS. Recommend a high F-stop since the focal point is diffeent for IR and the new lenses don't include an IR focal point and for starts add 4stops and trial and error from there.

wickedmartini Posted November 23, 2004 Share Posted November 23, 2004 I've been doing IR photography with my Fuji S2 digital camera and a Hoya R72 filter. It's been a lot of fun... For that IR look on the Photoshop end, Popluar photography has a neat little article online...

frankl Posted November 23, 2004 Share Posted November 23, 2004 the answer entirely depends on what equipment you have. If you happen to have a nikon coolpix or a sony cybershot, I have lots of information for you. Post your make and model. There are lots of digital infrared's in my portfolio here on photo.net.
