I'd like to see what happens when the red channel is blurred. Digital images like JPGs seem to blur the red channel more than the blue and green channels.

- klodolph 5y agoJPEG transforms the color into YUV channels. Y is the luminance, equal to R+G+B or something like that. The U&V channels (color) are often downsampled.
- aidenn0 5y agoY is basically "mostly green, a bit of red and hardly any blue" rather than a flat R+G+B. So blurring the green channel (as TFA does) is nearly equivalent to blurring the Y channel.
- klodolph 5y agoI guess that will teach me for saying "or something like that" rather than going into detail.
