    Rock Hyrax

    Taken on Table Mountain. Cute little creatures.

    Rock Hyrax


    At high magnification there appeared to be some colouration of some of its hairs, but the lens's chromatic aberration is automatically corrected, and I don't think it's noise - so probably "true" colour caused by refraction?

    Nicely captured, I don't see the colorization as a defect.

    Probably so, Dave.

    I viewed a portion of your crop in "Show Image" and selected the view of Hues only, which excludes brightness and saturation. As can be seen there are small areas of significant hue shift which support your comment about refraction, I reckon:

    Hmm...interesting shot, Dave. And thanks for the response, Ted. HOw does one correct the refraction?

    Dave, interesting creature. I have not seen one before...

    Thanks, Ted, in particular. I don't think you do correct for refraction, it's what gives colour to rainbows.

    For the zoology minded, s/he is the only member of its genus, there are three other species of hyrax forming a complete order of mammals, and their closest living relatives are elephants and manatees. So there

    Dave is quite right, re: rainbows and no need for correction.

    Another example is shooting an urban parking lot after it has rained, where pools of rainwater have that floating oil-film and the camera captures the film-refracted colors. Many insect bodies do it too.

    Cute critter, nicely captured - the only way to 'capture' them

    Interesting looking little critter. Funny nose.

    Yes light reflected off fur can do some interesting things. Under our typical overcast skies up here it can often be very blue.
