“True” color

How I usually define that (loosely) is does the subject in the image look the
same as what I’m seeing? Our eyes adjust dynamically, but the camera does not — if things look bluer or greener, I try another setting. Even so, an alternate lighting source will change things again. Open shade (outside, not under trees) seems to be best for balance.

Color and light

The diodes emit a blue spectrum light, the setting sun a red spectrum light, and sunlight filtered through a leafy canopy is mostly green. On top of that you have masking effects caused by the colors of objects surrounding the subject, and there is the fact that all humans perceive colors differently due to different distributions of red, blue, and green cones.

Color is determined by three factors: the micro/molecular structure of the subject, spectrum and intensity of illumination, and the micro/molecular structure of the perciever’s eyes and nerves.

What is a true color I don’t know.

Does the color remain true? White LED’s emit a rather blue light

Thanks Patrick!

I found these beautiful specimens right as the sun was setting. The light on top is from the sun. The light on the bottom is a trade secret haha, but I will say it is not from a flash.

Nice shot

Lovely! Wish I could rig up an external flash somehow …
