# Image and pixels

Just as some food for thought, because all RGB pixels are a combination of 3 numbers, isn't it possible to count through all of them to show every possible color? And if images are combinations of pixels, isn't it possible to count through every possible combination of pixels and show you every image that could possibly exist?

Trippy, aint it? =)

It is trippy, what you guys think, if you have a computer with enough power to generate half of the possible combination .

Is This A Good Question/Topic? 0

That's a lot of porn!

But let's think about that. say 256 colours at 640 x 480. Not that high a resolution or colour depth. If my maths is correct, that's (640 * 480)^256 images.

That's 1.45 x 10^1046 images.

Let's say you couls produce 1000 images a second.
That's 1.45 x 10^1043 seconds
4.71 x 10^1395 years

The universe has been about for 14000000000 years.
that's 1.4 x 10^10.

You're going to need a LONG time to do that test

I did get it wrong. It should be 256^(640 * 480). That's even bigger!
