Off the top of my head, I couldn't remember, so I went back to the raw files and was surprised to see that I actually photographed it both ways: horizontally and vertically!

Even worse, I photographed each panel seven times, so I could median-blend them into a single photo and reduce the noise level by 2.64 dB. Then I merged all five of the blended panels into a single pano using Photoshop's merge tool.

But to answer your question, this version was made using the horizontally oriented photos and according to RawTherapee, I didn't process the vertically oriented photos. Maybe I should do that now, because to my eyes, the sky is as interesting as the rest of the scene!

Thanks for the information. I may have to try doing this again. As I said, it has been a while!

Two more around-the-neighborhood photos from my 85258 project:





Seven as-identical-as-possible photos were taken handheld using a DIY, full-spectrum modified Samsung NX500 / Contax N 24-85 / Hoya R72 combo and median-blended into a single file to reduce noise.

Thanks guys, I feel fortunate that smoke was all I had to deal with when so many others lost everything.

Thanks - are you asking about the color? I'm using a full-spectrum converted camera with a Kolari IR Chrome filter on the lens. The filter is designed to be similar to Kodak Aerochrome color IR film.

Hi Alan,

If you are using the IR Chrome filter on the lens with a full spectrum camera is it correct to assume that this is what you see in RAW? If so, that would make it a kind of true color, not the "faux" color usually seen with IR produced by channel swapping and such?
