You're right. Similarly, I cannot express how good this site really is in just a few words. Having been an enthusiastic amateur photographer for decades as well as having worked in electronic imaging for about as long, this is one of the best practical illustrations of the subject that I've come across.

I'd highly recommend it to anyone who is seriously interested in the underlying 'mechanics' of imaging.

(Incidentally, anyone whose has read my many anti-JavaScript raves, then I'd only say this is exactly how JavaScript ought to be used.)
