The document discusses what the author learned about filmmaking techniques through creating the project "Fraction". Some key lessons included: - Shooting with a DV camera made it difficult to achieve certain visual effects due to technical limitations, but the camera was easy to use. - It's important to follow the 180 degree rule when shooting to maintain visual continuity, and to get a variety of shots including those requiring a hands-free camera. - Editing footage from multiple angles allows overlapping images to enhance psychological elements, and changing the pace keeps the piece visually dynamic.
