Catherine Chua Khay Ting : About School Work: 3D II : EYE

Week 6
Those are some questions my lecturer asked in class and he wants us to find the answer.

1. Human eye can see RGB or CMYK?

Human eye reproducible with RGB additive colour, and reproducible with CMYK subtractuve colour. So that is no exactly number of colour that human eye can see. Human eye can see billions of colours, RGB can reproduce 16 million, and CMYK printing 5 - 6 thousand colours.
I think the image show below will make people more understand.

2. How to get Gold colour in colour plate?

I found many ways to get gold colour on internet. For me, I'll mix white and little black to get grey fisrt, then add yellow to get gold.

3. How many megapixel our eye can see?

First, what is pixel? Pixel is a physical point in a raster image, or the smallest addressable element in an all points addressable display device. So it's the smallest controllable element of a picture represented on the screen. So megapixel is a unit of graphic resolution equivalent to one million or 1.048,576 (2²⁰) pixels.
And human eye is around 324,000,000 pixels, which is 576 megapixels.
This really show a huge different compare to Iphone 7's camera with only 12 megapixels.
