Title: Infrared photography

Hi everyone
I am thinking of doing some infrared photography. Could anyone advise me on a digital camera that would be suitable for this purpose?

Thanks Holly

Hey Holly,

I don't think the type of camera is that important as the effect is produced in image processing afterwards in Photoshop or similar.

Theres a tutorial in this months Digital Camera Magazine about producing an Infra Red effect on an image pop into your newsagent and have a look it maybe what your looking for.

Regards

Tony

Hi Tony

Thanks for the reply. I have been researching the subject recently and it seems that Some digital cameras are better suited to IR work than others. I have a Canon 300D and 400d and they are not suited to IR. I think I might have to buy a an IR converted camera for the job as these can be hand held.

Thanks Holly

Hi Holly,

If a camera is particularly suited to IR then i'm sure it will be quite expensive or lacking in some other area in which case it will only have a limited use to you especially if you decide IR isn't for you.

Check out images produced by an IR capable camera and the effect produced using filters in photoshop i think you will find that the difference is negligible, and you will be able to spend the money treating yourself to something really nice.

Hi Tony

I think you are right. The problem is finding a camera that is capable of taking IR images. I have phoned Canon and Nikon technical departments and they could not recommend any of their models to do the job. I have been looking at several IR websites and it seems that the older cameras are more capable of taking IR images using filters. The Minolta Dimage 7 and Nikon coolpix 950 seem popular. I might start with one of these and see how I go on. Some people have had their Canon SLRs converted also. I will pick up the magazine you recommended this morning. I will keep you posted.

Thanks Holly

:D hi holly apparently if you point your tv remote at your camera and you see a red beam your camera is infrared sensitve, hope this helps nick

Hi Nick

Yes apparently this is very true. My Canon 300D & 400D do not pick up the beam from a remote control so they are not suitable. If anyone does this test on their cameras and it picks up the remote control beam. Please let me know as I would be very interested in the type of camera they have.

Thanks Holly thumbup

I did sit through a lecture by some knowledgable chap on this very subject and I seem to remember that it has something to do with the fact that most Digital cameras are fitted with an internal IR filter.

I also seem to remember that the cameras that its easiest to remove it from were the Fuji range.


Edit
This web page explains a bit more

Hi Tom

Thanks for the info. I believe that the Fugi IS 1 is going to be demonstrated on Bob Rigsby's stand at Focus. I will get the spec on it.

Thanks again

Hello everyone.

I am new to the forum and noticed this post on infrared, I have a modified Canon and most of my work is infrared.
Hope you like this one, sorry if I have made any mistakes posting this.
Nice to meet you all.

Chrisy

Hello Chrisy and welcome to the DPS forum.

Great shot thumbup

I would be interested to know what you did to keep the blue colour in part of the sky? A layer in Photoshop maybe? Do tell.

Chrisy - June 26, 2008 02:28 PM (GMT)
Hi Tom.

With a modified camera for IR with a hoya R72 filter fitted, the images after the correct white balance is set should have a sepia sky instead of blue, swap the red and blue channels in photoshop, a slight tweak to correct the blue cast in the clouds and you have the finished picture.
