Very cool. I am totally ignorant about this technique. Is it a type of camera? A type of film? A filter?

Some cameras have the capabilities of doing this out of the box. I know some of the old Sony Cybershots (DSC-F828 for example) had this feature.

Most cameras now have a visible light bandpass filter over the sensor to stop IR wavelengths from hitting the sensor. In order to do this with most modern digital cameras, you have to get rid of this filter and replace it with a IR bandpass filter (DIY for a D90). Your camera can only be used for IR thereafter, but it's the only true way to do it. Using an IR filter on the lens is vastly inferior because of the layering of conflicting filters.

I tried putting an IR filter on my 7D. Even in very strong light it's very difficult to get any kind of photo and the focus really struggles. I think this was the best photo I was able to get and it's really bad. This was taken with my kit lens from the 400D (18-55 non-stabilized). I tried the nifty fifty but couldn't do much better.

I'm curious to know if anyone has tried IR with a micro 4/3 camera.

I'm planning to replace the filter on my old D80. Probably after the purchase of the D600 I'll do it.

I have converted recently my 550D to IR with Lifepixel but I am not very happy with the quality. I should have also gone for a non-standard filter which would give more colors but too late now. So far my experimenting hasn't really met my expectations. I'll have to work out what to do about that.

Why?

The problem is with focusing so images are not as sharp as I'd like. I chose to calibrate the camera for LCD Liveview which is much better than calibrating for one lens (usually 50mm) but the Liveview focusing on 550D isn't the best. I have also only taken JPGs so far as infrared in RAW does not work in LR4 nor CS5. I found out that it will work OK in DPP (Digital Photo Professional, there is an equivalent for Nikon) so I am planning to take some photos in RAW and see if that's better. There is a lot of information under this link:

Thanks for the explanation :)

I recently got my 5D converted to IR, and had it calibrated to my 24-105 lense. I've been shooting in RAW, bringing into photoshop via ACR, and editing from there. I've not had very much time to experiment, but I'm pretty happy with what I'm getting. Noise can be a big issue, but I'm still experimenting. There are a few (very experimental) examples posted in my IR Gallery.

Where did you do the conversion? What filter did you get? At what ISO do you get the noise? I haven't noticed it on mine. Re experimenting - most classical IR landscapes involve water reflections and formal gardens. I might plan a trip to the botanical gardens soon :)

Why?


i take IR on an unmodified 550D you can because the the BLocker isnt that strong it just requires you set up the shot before you put the filter on and use a WB from one of your previous IR photos as the WB for all photos then you get perfect IR images out of your JPEG's which i have done many of these with great effect!

the ones in my portfolio are pretty much straight out the camera i haven't post processed these for DPC but i have and have exhibited them and the output quality is definitely good enough not to have to have a modified camera, but moving subjects you will need a modified camera as it requires a longer shutter speed with a lens filter, but the charm of the movement for some is equally enjoyable as frozen movement...

When I first started at DPC, one of the photographers that really drew me into the site was 21.gif marbo with his IR photos. Some great stuff in his portfolio.

Fantastic portfolio. That's what got me interested in IR. It gives an alternative view of the world, escape into fantasy :)

For anyone interested, D50 is the Nikon alternative - crappy IR blocker inside the camera means great IR shots with a filter on. These can be picked up very very cheap these days.

It's also the camera that I converted myself (with the help of a friend). Bought the IR filter from LifePixel and did the home conversion. Now THAT was an interesting experience: we forgot to discharge the flash capacitor before opening up the camera. It discharged (into the air fortunately) with such a loud bang while the camera was open I thought that we had blown the whole thing up!

I love shooting IR.. photographing the invisible

Has anyone ever converted a Canon Powershot G5? I have one that I'm considering sending to lifepixel.

Today I went for a mini outing to a local little "wetlands" area near my home. It really isn't all that pretty, but the IR manages to make even THAT area look pretty good.
I used my dedicated IR camera (Canon 20D).

Full spectrum is the way to go. Gives you so many more colour options.
These are from a little canon powershot A480. I like the goldie effect which is around 590nm.

I'm planning on getting a new body this year and doing a conversion on one of my d70's...
