Square-by-Square Drawing

The video tutorial explains how to transfer and enlarge an image using a grid method. The original image is divided into a 1/2 inch grid, while the new surface uses a 1-inch grid, effectively doubling the size. The process involves transferring details square by square, starting from the top and working downwards, while considering handedness to avoid smudging. The tutorial emphasizes lightly drawing contour lines and using reference points to align facial features accurately. Once the transfer is complete, the focus shifts to studying and replicating the values and colors on the new surface.
