Adam's Apples

I took this photo back in October to show that the beautiful color of Jonathan (right) has the same deep tone as  Ruby Jon's . As his name implies, Ruby Jon is a sport of Jonathan—a genetic mutation that entails some difference or improvement valuable enough in this case for farmers to cultivate.

Today's photo mostly fails to capture Ruby Jon's intensely deep shade of crimson. In the past I've also been unable to depict the similarly dark hues of Arkansas Black and the mahogany reds of Black Oxford . This image shows a dark red, but the reality is darker. Does the problem lie with my camera, the online medium, or my own limits as a photographer?
