I figured I'd try something while I shot pictures of the motorcycles... I tried holding the IR filter, which is a 52mm filter, on top of the much larger filter on the 12-24... and this is what I got:



So I tried it quite a few times and here are some of the results after post-processing:















The rest of the images can be found with my other motorbike images here.

Dats Kool, feels like i am peering through another dimension, the blurry fingers ont he outside give a nice soft contrast to the circular peephole into the uberzone, not to sure about the subject mater though.

well executed abstractobatics from you again.

I think these are my favourite if the nnnnsic experiments so far... very cool

Let me guess, you didn't have an adapter for the lens you were using.

I agree with Scott, these are quite interesting.

Very interesting and creative Leigh. Believe it I still haven't had a chance to use my IR filter I bought months ago. Incredible but true. Will most certainly do that during my holidays after you rekindled my interest Leigh. Ta
cheers

These look even better than they did on the back of the camera. I think the most interesting are the last two.

What IR filter do you use?

I agree with others, I think the last two are the best, becasue they actually showing the IR effect. The others look like normal BW. Very intersting photos and effects.

does the extreme blowout have any effect on the sensor? kinda like using night vision glasses in daylight

Doesn't seem to. Just blows them way out.

Alas, a step-down ring is something I haven't acquired yet... but at this point, after this experiment, I'm inclined not to get one because of how successful this experiment was.

A few of my friends are going down to the beach this week and, aside for all the Bondi "rules and regulations," I'm inclined to take my camera down and try some IR photography using this technique at the beach.

I've been itching to repeat the phrase "public domain" over and over again.

And it's an R72 filter that Wendell is kindly letting me borrow.

Do you mind sharing how you get rid of the red cast?

I'm not someone who touches IR colour.

In the digital world, it doesn't interest me, especially with the internal IR filter inside our camera stopping us from really achieving true infrared.

In the digital world, IR black and white piques my interest especially because I'm mostly a black and white photographer anyway, so to get rid of the red cast, you convert the part that is infrared (in my images, that's where the filter was used inside the image... in most others, it'll be the entire image) to black and white.

You can do this however you please... desaturating, lab colour conversion, effects filters... whatever your way normally is will work.

Typically, in IR, you're supposed to frame the shot first without the IR filter, shoot it, then screw the filter on, and shoot that... and then blend the images.

Another way is changing the white balance either on the camera or on the computer to achieve a different sort of colour spectrum.

But being a black and white person, this doesn't particularly interest me as much as a black and white image does.

Really like the 4th one, I have tried stuff like this shooting through a sunglass lens.

The 4th one is also my favourite. Cool effect.
