Some people have had success. Generally I belive they convert the image to B/W. I am not sure if you just convert one color channel or the whole image.

There have been several threads on the subject. Here is an old one I had bookmarked.

..but not the best for IR.

Exposures are long and that results in some weird flares.

Underexposure and working from the shadows helps (use RAW).
The red channel blows out pretty quick.

The 28mm f/2.8 seems to be pretty good, but still a lot of work in post processing.

Conversion to greyscale isn't too bad;



The darker IR filters are even worse.

This any better??

Perhaps the subject of the photos has not been the best for IR. I am particulary glad for the post however because I now know I will not spent the money on a Hoya R72 filter. I have a 7D but I will continue to use my D7 for Infrared. I don't think there is any comparison betweeb the 7D and the D7. The 7D just won't do a good job.

Why would the brand of the camera make a difference? I'm interested because a friend of mine takes beautiful infra red pictures with his 7D, and I was thinking of getting a filter for my 7D.

Tried with 7D and hoya R72 and didn't have very good luck. Lots of weird flares. Had to do long exposures but since I deleted the shots long ago and can't post any info on them.

I saw there was a person modding cameras by removing the internal IR filter which basicly makes them a IR only camera. Might be interesting to try with a 5D. Maybe in a few months when you can get one for like 500 bucks.

 

[Cigar]

A friend with a D7 does beautiful things with an IR filter like this, I find it hard to believe that the make of the camera could make a difference.





He's obviously pretty good at Photoshop as well.

I was all set to buy one, but now you have me worried.

Do you mean a 7D, or did you leave a 0 of D70. If thats a 7D, then very nice.

I think a modified 5D would work well. And if you do this a lot, might be very worth it.

Here's a link:

Sony cameras with a Nightshot mode for low-light shots are particularly good for IR when used with the R72 and 8x ND.
Here's one from my V3

Maybe it's something the Sony/KM dslr will have too ;O)

Pixels proliferate but film is more precious.

Sorry, I meant Nikon D70. I still have to wonder what the difference in the camera brand would have to do with the filter's effects (or lack thereof)?

Well, I guess it depends what sensor is being used, and even if it is the same, does the camera manufacture or the ccd maker determine the IR filter that is put on the CCD.

 

[jeffkrol]

Not only sensors and filters but apparently lenses themselves all contribute to quality.
