They are all really cool...but that first one has a great tonal range, and I really like the whole feeling of it! Great job!

They are really beautiful just marvelous!
Can you share how you've done them, i've seen many but never care to ask how it's done could you help?

Very nice. I've been wanting to get an IR filter. I'll have to do it this summer.

Here's a tutorial I found for emulating infrared in photoshop. I haven't tried it out yet.

Pulled it down so I could read it over. Thanks.

I was playing around with IR in November and December. I really wish the 10D had better IR performance. It's almost unusable as is.

How large is too large and by what measure? Pixel dimension? File size? I can't find anything about it in the FAQ. If everyone who responds posts thumbs the pages can get quite heavy too. What is the prefered thumb size?

To Jeremy and Dee, I'd love to know your PP steps. Also, curious if you shoot in RAW, or adjust to custom WB with the filter on.

I've recently gotten into IR work, but it seems the 20D is not very well suited. These are pretty good, so I guess it's possible.

Possible but I find it very annoying. Long exposures, playing with focus, dozens of shots, etc.

Image 1 - RAW, ISO 200, f/22, 75s
Image 2 - RAW, ISO 100, f/16, 60s
Image 3 - RAW, ISO 100, f/11, 30s

All three were otherwise processed the same. Set white balance in the Camera Raw Plug-In with the white balance tool by selecting a grey point and flip blue and red channels with a channel mixer adjustment layer. If anything else is needed it's usually adjustment layers for additional levels adjustment or selective color enhancement.

Wow! 75 secs! Now that's patience! I guess that explains the movement in the sky. There couldn't have been much wind though. The leaves are quite in sharp focus. My samples were done at a higher ISO, larger aperture and around 8-10 secs, and I have much more movement in my leaves, etc. You can see some in this gallery, if anybody is interested: //mariomelillo.com/gallery/Various

BTW, Dee, I think those shots are great! Those would be worth the effort for me.

Thank you. Couldn't feel any wind at ground level. Though you can see what I mean by it annoying me. That first shot is one of about 20 that I took. I chimped every time because the 50mm f1.8 mk II doesn't have any IR marks on the lens so the process becomes take a bunch of shots to find the right exposure. Then start adjusting the focus little by little with each shot trying to guess the right compensation for IR. All the while you have to wait around for people to be moving so they don't burn into the image. The one I posted still has a guy standing next to the doorway that looked like he was going to keep moving but then decided to stop for a second. The image looks good printed to a little over 9x6 but I don't think it has the quality to print larger. Perhaps with some more work maybe.

Here is a different one...
EDIT: Old outdated link removed.
RAW, ISO 400, f/18, 30s

No wind here but still couldn't get focus right. I was hoping the smaller aperture would make things acceptably sharp but no luck. Noise also was an issue at the higher ISO.

The color IR look is cool though. Perhaps cool enough to look into buying a used Minolta or one of the other digicams that one can use handheld for IR. I've seen quite a few examples from cameras without a heavy IR filter like Canon uses and they produce some fine results.

Do you have any other lenses? What size filter do you use on your 50mm 1.8? I have a 58mm R72 that I use on my 50mm 1.8 (using a 52-58mm stepup ring) and the same filter on my 17-40L (using a 77-58mm step down ring). Because of the crop factor on the DSLR, it works fine. Obviously the 17-40 is much better suited for landscapes and also has the IR focus marking on the lens.

Once again, your images give me hope that I can get some decent IR shots using my 20D or DRebel. Well done.

I have several other lenses but I only have a 52mm R72 filter. I purchased it for my old Olympus C-3040z becuase it was big enough to cover the entire zoom range of that camera and fit the standard Tiffen lens tube. However, all of my other lenses for the Canon are threaded much larger than 52mm.

probably the biggest advantage of the modded camera is that you can compose through the viewfinder the exact same as a normal shot. Also, you don't need to worry about the focusing... Of course, you have to really like IR photography to take a D60 and destroy it :)

A few more...
