Sigma teal&orange mode w/IR Chrome filter


Recommended Posts

Sigma recently added a new "Teal&Orange" toning mode to the sdQ-H firmware, so I thought I'd try it out with my Kolarivision IR Chrome filter, which I haven't used in while. For this set, the sdQH is CWBal on neutral gray, then I switched from Standard to T&O mode. Some brightness, contrast editing, but basically SOOC colors.

Interesting effect, although it seems to be reversed. From a colour grading perspective, orange is supposed to go into the highlights and teal into the shadows.

It's a kitschy effect , but I was intrigued by way it renders green grass in orange tones.

 

This normal, visible light shot, was taken with my on-lens hot mirror filter, in T&O mode. It almost looks like the orange foliage, that IR Chrome produces on my Sony a7R.

Not a hint of orange on the Sigma sensor.

Here's a comparison shot of my trashed fire pit, in Standard and T&O modes.

Thanks Akira!

 

Here are a few more, showing the extreme color contrast between new growth and dead material.
