More Micrographs...
At right is a 100x view of part of one needle from a Noble Fir (our Christmas tree this year). I'm guessing that those white spots are where the waxy and odiferous stuff exudes.
At left is a 100x view of my LCD screen, showing part of a letter ‘e’. If you look carefully, you can see that there are rows and columns. If you look in one row, you can see that each group of three stripes is the same width as the row is high – each of these groups is one pixel. Each pixel contains one red stripe, one green stripe, and one blue stripe. By adjusting the brightnesses of each of these colors, the pixel (viewed at a distance by our naked eye) appears to be a color that is the combination of these three colors (this is the “RGB”, or red/green/blue you may have heard of). To my eye, that ‘e’ appears to be black on a white background – but it sure doesn't look like that in a magnified view!
