Ahh, that's why it looks bigger in real life

I'm really fascinated by Michael, he always talk about interesting non boring stuff, also explains it very very well.But most of all i like how he comes up from the bottom of the screen and starts talkin

One reason why many Pro Photographers print portrait shots "back to front"...so you get the "mirror Image" look that your used to.

Left and right is just as parallel as up and down to the mirror. That's a nonsense explanation.

The real explanation is that mirrors do not, in fact, reverse the image from left to right. They reverse the image from front to back.

If you raise your left hand, does the reflected hand on your right go up? No, the one on your left does, because the image is *not* reversed left to right. When you look in a mirror, you get the same view you'd get if all of the object being reflected were transparent save the very surface facing the mirror. So a "reverse" word isn't really reversed - you're looking at the front surface of the letters from the back. Hold up any sufficiently light t-shirt with writing on it to a bright light, and you get the same exact view that a mirror provides, albeit with much lower fidelity due to the fabric still being in the way.

#5 If that is the case what happens if you take a photograph of say a clock in a mirror on an iphone (appreciate it wouldn't work on an android) holding the phone underwater, pointing upwards at a slight angle so that the image is reflected onto a second mirror, then that image is photographed using a digital slr camera held just above the water pointing upwards.

To #6 : #5 is correct, you see yourself inside out. It's a bit hard to grasp and for common sense it's better to just think of it as reversed. The problem comes when we think of yourself looking at the mirror as 3rd person and start to move that scene and actors in your mind. What then happens, in your mind, is not true, it's just our interpretation of the the reality. We have never experienced being inside out. It's more of a mathematical mirror than real but it explains very logically how up and down is not reversed but left and right is, in our mind, reversed. In true physical world it's simple as a brick to understand how mirrors work. Thus the self image we have in our mind is reversed because we take that scene out from the surroundings that created it correctly and we apply 3rd person view incorrectly. In philosophical sense it's very interesting indeed... If we are inside out in the mirror and carry that image with us, are we then actually inside out every time we are NOT facing a mirror?
