Videos of penguin vision experiments

These are as many of the videos as it is possible to upload obtained when performing experiments using either a moving circular striped target or a rectangular, checkerboard target projected against a wall using a LG CineBeam PF50KA Projector (LG Corporation, Seoul, South Korea). The targets consisted of either achromatic stripes, stripes designed to provide maximum contrast to short and medium but not long wavelength cones, and stripes designed to provide maximum contrast to long but not short or medium wavelength cones, or a colored checkerboard with those same three types of coloration.
