digital photos

Greetings to all you digital photo experts,

I have just taken several photos of longipes 'Katsuragawa Beni', and
while observing the photos, I have noticed:

**when the photo is shown at 50% size, the veins are red all the way out
to the end of the leaves and the base of the leaf is very red;
** at 75% size, the red is more concentrated in the veins, less scattered
and heavy in the base of the leaf; and
** at 100% photo size, the red is visible up 1/3 of the way into the base
of the leaf, but not visible in the veins the rest of the way to the leaf

The 100% size is similar to when the necked eye observes the plant.  Now
does this means that the red is there, but becomes observable only when
the pixels become more concentrated at 50%, making the red show up
better?  Better take Jim Wilkins' class at Hosta College - 3 weeks away!.

Would welcome explanations???  Kevin and Jim?
