infrared with digital???

Hello everyone, I recently saw a photography class being offered for digital infrared photos. Is their such a thing now? If so what type of cameras allow you to take infrared shots. If it is just done on photoshop or something can anyone tell me how, or give me any info on the subject or where i can find info. Thanks A lot

Almost all digital cameras will allow for IR photography. Just some are better at it then others.
I shoot IR with my 20D, 300D, and F717 all the time. The key with using a dSLR is to do a custom WB first then take your IR shot, and you exposures will range from 4-8 seconds each usually. Of course you will also need an IR filter like a Hoya RM72.

Here are some samples of my IR work done with the Sony DSC-F717 + Hoya RM72 + NDx4

Is there somewhere I could look to get some more detailed instructions? I really enjoy infrared and I thought I would not be able to do it with a digital. this is exciting news to me. I shoot with a 20d as well

This may help:

You say take the picture first? Can you give me a run down of exactly what you do. what do you set the white balance to, shutter, apeture, etc. Thanks so much. I am currently reading that web site you dave me the link to. Hopefully that will help. By the way your pictures are great. Did you take any of those with the 20d? That is what I shoot with

Thanks, actually none of those were with the 20D.

You take a picture first and set a custom WB from that picture. Then take the picture you want using that custom WB. Aperture I usually set to f/8-f/11 and you will need to experiment on shutter times, they will vary depending on available light. You will also need to adjust your focus since IR doesn't focus quite the same as normal light. You also ave to be careful with some lenses as they wil produce "hotspots", like the kit lens. That link will be able to give you far more indepth details.

Hello, I have been reading some post about using the 20d for infrared photos. Lots of them say that you have to modify the camera and remove the IR sensor. Is this true. I do not want to mess my camera up. Also you said you take a custom white balance? Lets say for example I wanted to shoot just a large tree, would I take a WB of the green leaves and set it at that? Thanks a lot...

Yes, you set the custom WB just like you would any other WB, except you have your IR filter on the lens when doing so.

You do not need to modify your camera to do IR. Modifying your camera just makes things much much easier and allows you to have hand holdable shutter speeds.

Absolutely.. with the right gear.. digital IR is far more approachable than film was.
Here's some examples taken with an IR D60

When setting a custom white balnce,. you don't use a white card,. you want to use something giving off a lot of IR heat..
Best option is a feild or lawn of grass on a very sunny day.

Someone recently posted on one of the hack-it-yourself forums (I don't know which one) a way to cheaply modify a $20 webcam for infrared video. The first step was to remove the camera's IR-blocking filter, which is webcams is a little piece of plastic. The second step was to use unexposed film as an IR-passing filter.

These same techniques might work for you also.

This thread in the Digital Infrared group on Flickr has a number of good links in it.

A trick if you don't have a Hoya RM72 or other IR filter is to use an old 5.25" floppy disk and take out the film inside to cover your lens as an IR filter, and yes it does work!

Hey thanks for all the tips guys, I am gonna order a filter and give it a shot. I found an old thread on this web site where people were talking about this same subject. Lots said there pictures come out red and they have to change them in PS. Is that how they all come out? Red. Then you have to change them. Or do you get that nice white look when the picture is taken? Thanks a lot I cant wait to try this,

PS- let me make sure I got this right- Put the camera on a tri-pod, set a custom white balance to something green (grass, etc.) with the filter on. Take the filter off and manually focus the shot. Set apeture to about f8-16, set the shutter to about 20sec. And ISO about 100-400. And then experiment from there?

Also, I have only a few lenses- canon 18-55 kit lens, sigma 50mm macro, tameron 75-300mm, and sigma 17-70mm. Which do you think would provide the best results? Thanks so much

I shoot all mine in RAW and adjust them. Check some of the links that were provided regarding lenses. I believe I read that the Canon 50mm f/1.8 was one of the best ones to use.

Theres came out red because they didn't set a custom WB first. If you set the custom WB then you will be fine. Then once opened in PS you will need to swap your Red & Blue channels and you are finished if you want to be. Easiest way to swap is open the Channel Mixer and set under the red Red=0 Blue=100 then drop down Blue and set udner blue Red=100 Blue=0
