Great explanation and visualization. The only point I think it misses is *why* our brain thinks focus-tilted images appear to be miniature. The very narrow depth of field that tilting allows is nearly impossible to achieve at greater distances with a standard lens, and usually only happens in close-up photos. So we have been conditioned to understand that a narrow band of focus means we’re looking at a very close-up picture.
Thank you! this makes so much more sense to me now seeing the light physics visualized. I always love knowing how something works so I can better utilize it.
Overall this is a good intro video, but I think your diagrams could be misleading people in understanding how a Tilt-Shift focus plane moves. Your diagram shows a single arbitrary pivot point (when in fact there are 2 pivot points) that the focus plane is pivoting on when the lens is tilted (marked as the Scheimpflug Intersection on your diagram). This is wrong. Tilting the lens moves the pivot point closer or further away - up or down the sensor plane, which causes the focus plane to pivot along the second pivot point which is where it intersects with the focus point (should be drawn as a straight line perpendicular to the sensor plane and the pivot existing at the focus distance on that plane). Focusing the lens once shifted will simply pivot the focus plane on the Scheimpflug Intersection since it's moving one of the 3 triangle intersections - the sensor intersection is static. Knowing how focus affects this helps a lot when trying to determine the best starting point for focus and tilt. I think you are missing this in the animation, it shows the focus plane pivoting in the way Focusing causes it to pivot, but not the way tilting causes it to pivot by moving the Scheimpflug Intersection.
Tank you very much My Brather for this video . I have a 17 mm TILT lens It's excellent at photographing life, but Not good at photographing the city It's not like 24 mm TILT Iens Is this true or not? Please correct my information

Best clear, concise explanation of tilt EVER.. Thankyou..
Absolutely the best explanation of what a tilt lens does. Thank You!
Thank you for that concise, clear explanation.

Nice
I understood nothing 😢
