Hey everyone,
I made a tutorial about the post processing that is required with digital IR photography and since I think there are a lot of people out here that might want to take a look behind the scences of IR photography I thought I might share it.

here is the link: [link]

I hope this helps someone.

Caution: noob question

How can I take an IR photo? I know that in the old days there was film, but is there a setting on the DSLR for it, or is there a filter that would allow only the IR light to pass?

Pardon me if this is horribly dumb, but I really don't know how to get this done. Your tutorial was awsome though. I just can't get the image to begin with...lol

ah dont worry. we cant all know everything. well i know i dont :P but as for digital ir photography you need a filter that blocks out visible light. the one i use is a hoya r72 and it blocks out all light under 720nm so there is a tiny but of visible light for the eye.

then you have some cameras that are more sensitiv to it and some that are less. my eos 350d is one of the less sensitiv ones but the d70 is great for ir photography so i suppose your d50 would be doing a good job too. :D

That is fantastic news! I am going to have some fun giving this a try. Thanks for the reply.

Does anyone have experience using the HOYA RM72 on the Canon 20D? The filter goes for $270+ in the 77mm size - seems steep, so I want to see if anyone has had experience with it on the 20D. I would assume it's similar to the 350D lucas uses.

Lucas, thanks for posting!

That is pricey. Best I could find was just at $200 on e-bay. Expensive filter.

Marbo has taken a lot of great infrared photos. Just check his profile, especially his camera he uses soley for infrared photography.



In the photographers comments in that photo is a video tutorial as well.

Very nicely done tutorial and you have done this with a 350d which is very differcult to handle for ir.

Wow that is great. I am going to have to try this out.

I recently got my Hoya filter in and have taken about 10 pictures with it on my D-50. The best tip I read was that you set the white balance manually with the filter on the camera using a white piece of paper (or 18% gray). When I do this the pictures comes out with the surreal look right out of the camera (instead of the red color as in the tutorial). This will save you a lot of post processing time....

can I take IR-photos with my EOS 30D?

Wow, I think I stumbled into the Spring of Knowledge, with respect to IR. This link answered all of my questions!

This is totally a rumor, but I remember reading somewhere that most digital cameras have an IR filter over their sensors. I think I saw a website walking you through removing that, step by step. I wouldn't recommend it though...

AFAIK, you still needed the filter...

(Speaking of, did anyone try a DIY filter made of blank, developed film? Another rumor stuck in my head tells me it makes a great home-made filter.)

Can anyone confirm all these "rumors"?

Consider the first question confirmed: 350D Conversion

I can't speak to the second one.

adyus, the first rumor is true. there is a site that does the removing for you and also adds a ir filter onto the sensor so you have a fully modded ir camera. but i suppose youll have to know how imporant to you it is to inverst so much money into it.

for everyone asking if their camera can take ir photos. i dont know. i only know that the ir photos how i have them are from a eos 350d and that nikon d70 cameras take extremely good ir pics.

jchamp: i suppose its arguable which if its morecomfortable to set the wb on the camera or set it later onthe computer but i suppose that for people that dont have the raw format the computer question kinda falls away. but i think raw editors have made our job pretty easy now :D

Ive got some lens at 77mm and 60mm,
is there an adapter to use filter on both?
What brand is prefered?
and lastly Jchamp posted about setting white balance on custom I have a nikon d70s is there a custom setting you can store on the camera?

Lots of questions as IR is awesome I have only post processed regular color shots and not real happy with this

Get the largest for 77mm and step down rings to 60mm
Hoya r72 filter is a favorite.
Once you preset the white balance it will remember this until you set it again on my d50 but i beleive the d70 has some extra white balance functions which may allow more custom settings.
