I never thought about any of that before but it totally makes sense.
When learning skills that are depicted visually, I’ve found it’s better to get a book that’s old enough to have illustrations or diagrams if possible. 2d line drawings in black and white, or with judicious use of 1 or 2 other colors. A skilled illustrator can show exactly what you need to see but photographs necessarily have various other stuff in view. Illustrations can clearly depict motion, hidden parts, or changes over time in ways that photos can’t hope to.
And that’s without the benefit of assuming a lot of knowledge on the part of the reader the way you can do within a profession like you are describing.
