}Wan 2.6で作った実例
The camera stays on the two of them through all three shots. Three shots cut from the one kitchen frame. 1. Close: the knife going through, her forearms dusted with flour. 2. Medium: the pan catches flame and lights both their faces. 3. Close: he comes up behind her and reaches past her waist for the pan, her head tipping back against his shoulder, both shirts soaked through with steam. Cinematic, shallow depth of field, heavy film grain, kitchen steel and gas blue.
