462 - Who knew?
Well, in fact, some of you know that there is a lot more to pixels than meets the eye, so to speak. I updated myself on colour, found out that pixels can be square or rectangular, and that there is such a thing as a sub-pixel. All of that (as well as CMYK, the colour model for printing) is more than we need to know. However, I did amend slide 14 from last week, which now reads:
Pixels and Colour
one or more 8-bit numbers renders 1 pixel (bits per pixel - bbp)
expressing intensities of red, green, and blue values (RGB)
not the same as our childhood “primary colours”
8 bpp can render 256 colours
16 bpp can render 65,536 colours
24 bpp can render 16,777,216 colours (most monitors)
48 bpp can render “a continuous colourspace” (professional image applications)
