Each color channel (red/green/blue) has 256 levels between black and white. This is due to the image information being 8-bit in each channel (2^8 = 256). Computers don't count in ordinals, so 0 is the first digit, and you stop at 255.

0 = black
255 = white

Going to 16-bit, you get 65,536 levels between black and white, which gives much higher fidelity and more subtle differences between hues and luminosity.

In fact 16bit in Photoshop is really "just" 15bit (from 0 to 32768). If you want to test it yourself set an eye dropper to measure 16bit in the info palette.

But the rest is 100% correct of course :-).
That's btw. also why 50% gray (128/128/128) goes to 127/127/127 while inverting (because 255/2 = 127.5, not 128).

A little off topic though ;-).


To the OP: many folks just describe their work as high end because they want to tell everyone that they'll deliver best quality.
If they're really doing is another question, but since this term is not bound to a test or something it's easy enough to call yourself high end.

Re: Really hate the expression high end.

Most pictures doesn't look high-end even thou they ment to be, because of the price. Many photographers would like to have high-end rtouched photo in 1 hour time. At least they would like to pay for 1 hour :-) That's why a lot of high-end called pictures are rubbish in fact.

Yep! Thanks for the correction - it's easy to get on auto-pilot and forget details like this. And if we go a bit further, most camera sensors are limited to 10-14 bits, so there's a lot of wasted 'space'.

Back on topic, I think the question has been answered by a few here... there is no official metric, so it's just words

Re: Really hate the expression high end.

I never seen picture that wouldn't need at least 6 hours of retouch to become "high-end".

Re: Really hate the expression high end.

Personally, high end has more to do with working to a certain standard rather than a time or budget limit. Anyway Bleifuss, I was joking with you - notice the winking eye!
