I've been looking at this guy's (http://zardo.deviantart.com/) work, and I noticed that he used a Hoya r72 in one of his pics. Do you think it's necessary to pull off this: http://zardo.deviantart.com/art/Is-it-the-end-85493143 image?

Apparently it's some sort of infrared filter thingy.


In all honesty, I have no idea what it does.

It's for ir work. You would have to do long exposures or mod your camera. And if you mod your camera it will no longer work for normal photos. But you can get some cool landscape stuff doing long exposures. You will also need a version of photoshop that has a channel mixer, read not elements.

What is the filter size on your lens. I have a Hoya r72 laying around that does not fit any of the lenses I currently own. If it will fit your lens I will mail it up and you can paly around with it.

I have PS CS2 :)

I don't particularly want to mod the only body I have though :(

The only lenses I have right now are the 50mm and the kit lens (they are in my car atm, so if you don't know the size -- I think 58 -- then I will post that when later tonight)

Yep, kit is 58, 50mm is 52.

The filter I have is 52mm for the 50. You can have it if you want to try it out.

You could probably come close to something like that with photoshop. But I doubt you would be able to use photoshop to make something look like it came from an IR converted body.

I've seen photochop versions of IR. It never looks like a true IR out of a camera.

there's no way it CAN look like real IR, because it doesn't have the same spectrum.

what the "ir" post actions do is basically lighten the green channel a lot.

yeah - speaking from someone who has a converted XT, the actions never look right - and im not good enough to make it from scratch.. (ie re-paint the entire image to look IR)
One thing though is with the 18-55 + R72, you will usually get a BAD hot spot in the middle of the image. The exposure time required + not being coated for IR and what ever lens design that lens has usually ends up with a hot spot in the middle of the image. Unfortunetly, without a camera that you can remove the filter (Sony f707) or an older PS (canon G1, G2) the DSLRS dont do well with IR without modding them. The IR cut is to strong to shoot through..
TRy it if its free but otherwise -> save your money
