This polarizer draws on Mondrian's classic geometric color aesthetics, uses red, white and blue vertical blocks to divide the body, and distinguishes functional modules by color: the red holding area integrates flash and sensing elements, the middle white carries the main lens, and the right blue block is installed with a viewfinder window. The outer ring of the lens is matched with a blue dotted scale ring, and the colors echo each other, balancing the monotony of the minimalist body. The tough and neat contrast color appearance is different from the conventional Macarons in the market, taking into account the texture of retro film and modern art design. It is small and portable, suitable for daily recording and punching cards. It takes modern abstract art with you, and every shooting is a color aesthetic freeze.
