Got my dRebel, want to InfraRed but how

[chadaw]

Now that I have my dRebel, what do I need to do or get to do some InfraRed? A bit new to InfraRed.

Thanks,

For starters, an IR filter (Wratten 87). If that's too rich, in decreasing preference Deep Red (Wratten 29) or Red (Wratten 25).

You can go for Hoya R72 filter. Search (either here or on G-series forum) will fetch enough information to get you started with IR.

I don't believe that Canon DSLR's will capture infrared info. Most digital SLR's have a filter that blocks out infrared info. This is due to the fact that infrared light causes problems such as red halo's etc. Supposedly you can determine if your camera will capture infrared by photographing the end of a TV or VCR remote while pressing a button on the remote.

There are several plugins for Photoshop that will give an approximation of the look of infrared. Fred Miranda has one that I use. I think that it looks pretty neat...but I don't have a film camera that is infrared capable to make a comparison to the real thing.

I've done quite a few infared shots with my digital rebel. Using a Hoya 52mm IR Filter, on my Canon 50mm f/1.8 lens. Works out real well.

Here some lens to some of the shots using the filter.

The last two being photomanips of handheld IR at high ISO.

By the way I used the 50mm f/1.8 as my special FX lens, as the speed of the lens is good for not having to expose as long, and getting filters for the 52mm thread is far cheaper than getting threads for say my 28-138 USM IS which is a 72mm thread.

I've done IR on a 10D with a Hoya R72 filter. It worked very well. Be warned that long exposures will be necessary (use a tripod), as the sensor is not particularly sensitive to IR radiation. You'll likely have to use manual mode and check your exposure by the histogram. Also, IR radiation is focused at a slightly different point from visible radiation, so unless your lens has a depth-of-field scale that has markings for infrared, you might want to stop down to ensure sharpness. This, of course, will require longer exposure times. I've typically used exposure times of 15-130 seconds for the conditions I've been interested in. This has lead to some interesting effects when moving water has been involved.

Be warned as well that some lenses give "hot spots" in the middle of the picture. Apparently the origin of this phenomenon is obscure. The Canon 50 f/1.8 lens works well. Reportedly, the f/1.4 version does not. I've seen a list of what does and does not work somewhere on Photo.net, but I can't find it at the moment.

Here's a general thread on the topic:

Enjoy!

Thanks, I just checked out those shots from kb244 and they were cool. And I had skimmed that one infrared link last night via searching on google. So thanks for the info and the links thats what makes this forum great and friendly. If anyone else has any more to add GGGGRRRRRRRRRRRReat! Particularly if they know of any good books on the subject or more links or examples done by dRebel (300d) or 10d.

Thanks again.
