Orange Goblins

Why? I'm not sure why, but I wonder how my photos from Goblin Valley this morning are showing the rock formations and dirt as so orange/yellow, when they were actually quite brown, like brown clay. I was shooting with my SD1 Merrill. Here's an example:

Here's a shot from my Nikon D810, which shows a similar scene, but as you can see with quite different color, though the color from the Nikon seems a bit pink to me:

Both cameras were set to Sunlight white balance, and I shot during the early morning, just after sunrise.

I adjusted the hue of the yellows a little, reducing saturation of the yellows a bit too, and got this much more realistic color:

I think needing to do this is a bit weird, don't you?

Hard to say, Scott, because neither image as posted has an embedded ICC profile.

Of course, that's never stopped me analyzing your stuff, so I'll be baaack ...

Here's the OOC jpeg Ted:

Well, a speedy analysis in the GIMP tells me that there is 20 degrees difference in hue betwixt the two. While I can not guess as to why that might be (beware circling sharks) , I did once sell an SD9 which, under fluorescent light, had similar difference in the reds to a trusty Nikon D50.

Shoulda sold the D50 which I did eventually ...

P.S. just missed your OOC image.

Not weird at all. Iron oxide pigments are always difficult for 3-primary photography, because there's a kink in the spectrum.

If you want accurate colour, scrape up some of the sand, mix it with acrylic medium, and make a painting.

Or try some of the colour modes in SPP, or a program that has HSL adjustments with more than the six colours offered by the GIMP. You need a slider for Orange.

There's an "HSV Equalizer" in RawTherapee which can adjust any Hue, FWIW.

Interesting Don. Thanks for the info!
