How To Zoom In and Out
In the upper right corner of the photos on the “kentmcbee” or “portfolio” menu item pages you will see a square made from four points. (Note: It is not visible from this page).
Clicking this square will show the full un-cropped photo. Clicking it again will return to the photo filling the screen.

This option works from the kentmcbee main page or any of the Portfolio pages.
