Slide 1-1-3, the Stage Micrometer provides photos of each magnification and a brief explanation of what the "pinch zoom" did mathematically to the magnification and field width measurements. I decided to go with "rectangular views" versus the exact circular fields of view when taking each microphotograph. This makes the images much larger on each PDF and avoids the large black areas around the circular field of view.
Later, I might add labeled and unlabeled versions of each PDF, but for now they are unlabeled. Use your notes and book to guide you through the images. Primarily you need to be familiar with the 400X view on each, unless some structure is particularly large, or a specific cell is of interest. That is why all magnifications are provided, even if you don't need them.
To avoid any confusion, I kept the traditional 40X, 100X, 400X, and 1000X magnification labels on each photo, though technically, they are closer at 53X, 135X, 537X, and 1333X due to the "pinch zoom" I used when taking each microphotograph. If you are confused about the magnification comments here, don't worry, it is really not that important.
If you are really into histology, you can estimate the various sizes of cells, or fiber thicknesses, and more cellular ultrastructures by using the photos of the 2mm micrometer. Later, I will probably add scale bars to each photo so such measurement are easy to estimate.
Because one slide is usually not enough, some tissues have multiple slides to more fully demonstrate the normal histology. Gaps between slide buttons are for future slides to be inserted.
