As the reddish backlight is from the gelled flash in the fireplace, it technically might be reproducible. But if I don't use the main flash, I'd have to increase the ambient without having to push the exposure so much afterwards. Would that change the balance of the light from the gelled flash? I don't know. I may have to try... If the cat will pose againI very much agree. I wonder if you could could get the same thing again if you wanted to, or if this was a camera one-off?
