Color Gamut: Green Shirt in Sunlight

Get NEC PA wide gamut display at B&H Photo.

With modern digital cameras, color gamut is far beyond the sRGB color space, and often beyond the AdobeRGB color space.

My NEC PA302W display and the late 2015 iMac 5K both have a display gamut far beyond AdobeRGB. Moreover, today’s printers have gamuts that exceed AdobeRGB, including colors rendered with inks like “Vivid Magenta”.

The internet is full of bad advice. In particularly, a workflow in sRGB is a terrible choice: many images will of course be in sRGB gamut, but a significant number will be out of gamut, with sRGB destroying both color and detail. While output may need to be converted to sRGB for many purposes, it is untenable to work in sRGB for the “master” image.

My previous work on color gamut in DAP explains various issues and gives examples. I’ve just added a new example of a rather ordinary shot in sunlight with a rather ordinary green T-shirt, which changes radically in color and contrast when converted to sRGB.

Color Gamut Example: Green Shirt in Sunlight

This example is with a 15 year old camera, the Nikon D1X! Which shows that color gamut is not just a concern for recent digital cameras.

Includes screen shots of how to preview color gamut in Adobe Photoshop CC.
