Description
From our first walkabout with the Sigma to practice IR somewhere that wasn't a backyard. It was crazy hot and we had to return home before melting, but it was a useful trip.
Came back again on two other days to try different things (with the heat also chasing us away each time), and I was finally able to figure out what I was doing wrong with the custom white balance, so there'll be some false colour stuff coming too.

I dunno what's 'wrong' with the white balance in this one, I really like it the gradient on the leaves looks almost exactly like steel at forging temperatures!

Thanks, nice to hear the heat came through
and white balance is about getting the colours how you want them, so it's not really a factor in B&W. I was having a hard time with it at first, so fell back to B&W to cover for it

There's something so magical about black and white IR photos. This is so beautifully dreamy

Infrared brings really out those branches.Β Β

It sure does, though I did have to process it a little to counter the IR hots pot this lens produces. All your IR images look to be free of this, is it thanks to the lens or processing also?

My main concern is that some parts of the photo are overexposed, especially with the panoramas. I have the Canon's L-series lens that I use and I don't remember that there has been any hotspots with the converted camera, when I tried taking IR pictures with it using my normal camera and IR filter those pictures were really awful. So it might be the lens.Β
What I've learned is to take pictures when the sun is behind me or on the side, never to take photos where the sun is directly in front of the camera. And overcast weather is better than clear skies.

Me too, it's been a learning curve to figure out how to best expose things.
I found some advice that sometimes on a lens with IR hotspots stopping it down can avoid it, and that was the case on the lens I had most problems with. Just means I wont be using anything higher than a 760nm filter handheld.
Lens flare is pretty crazy when the sun is in front of you

I tried to find my instructions that I got when I bought my IR camera, the seller has done camera conversions for years. But I didn't find them. There was a certain F-stop that he suggested using and the camera was set to use AV or TV program, I can't remember which. I have to admit that I started to use manual settings almost immediately, I am used to it.Β
And lens flare doesn't make IR pictures pretty, when I first tried IR photographing with IR filters I thought those might look nice. They don't.
