05-19-10 – Skylines

Thanks and now it looks like 2010-05-19 08:02:33 PM has disappeared 🙁

I shamelessly stole the idea from Peter Root.

My innovations were 1. using a puddle of superglue to hold the staples in place and 2. not trying to make any meaningful statement about the ephemerality of the interwoven strings of moments comprising and compromising our lives.

Thanks for that 🙂

I have to disqualify my lightning shot with the Pleides picture; I was poking around this site (wow, there’s all sorts of cool stat’s available; U-man; you should be ashamed of yourself for hogging all the glory!) and I found that I used a cropped image of the same shot in ‘Let there be light’. Not fair. Disenvotentate it.

Such is life. Poop.

Soosh – I’m curious about the blue sky in your IR shot. Did you swap the red/blue channels, or is it unfiltered IR + visible?

I don’t remember if I did channel swapping on that particular one or not. The camera was a borrowed 10D with the IR doohickey removed from the sensor, there wasn’t an IR filter on the lens. So I think it got some visible in there, too. On an overcast day, I got a lot of purple tones to the shots I took. You can see more here:

on a clear day looking straight up, I got really intense black skies, like this:

but closer to the horizon, the skies changed

then when it was all foggy and overcast, I got this kind of tint:

I think I must have done channel-swapping on the skyline picture. I don’t think the in the trees ever showed up like that straight out of the camera.

I’ll have to go back and try to find the raw files at home to see what they look like.

Hmmm…..

Has there been any discussion about this? I’ve seen lots of other people using digital IR from time to time in the themes, and never really thought about it. Now that I’ve started playing with it myself, and researching/learning, I’ve realized that the blue sky effect comes from the (pretty standard) process of swapping the red and blue channels. I was planning on bringing it up in discussion at some point, since I’m leary about using mine under the thoughts that channel swapping is too software intensive. Don’t get me wrong, I’m not saying you should pull yours, I’m just curious if a decision was made before I came around, if it should be unaltered only from here out, or, since it’s been used fairly commonly in the past, let it be. Even unaltered out of the camera, you can get wild effects just by changing the white balance. On the road trip, I was shooting IR with WB braketing, and getting three completely different photos.

Great stuff in your directory, BTW. Here’s my foray into digital IR so far, All of them channel swapped, some with B+W 099 (orange) filter, some with Ha+IR (red astrophoto) filter.
