This page assesses Leica M10-R for white balance and tint required for raw processing in Adobe Camera Raw in mid-day sunlight around the northern Wintern Solstice with slightly hazy skies at an elevation of 4200 ft ~= 1280 meters. In such conditions, the sun is low overhead and the light is relative warm (low color temperature).
The impact on color rendition is also examined as it varies significantly depending on the choice of Camera Profile—an unusual situation. You’ll want to read this page if using the M10-R and using Adobe Photoshop or Adobe Lightroom.
Includes settings for both the LEICA M10-R and Adobe Color profiles.
