While things have changed a bit, the general ideas in this video are essentially the same today. This is a must see for anyone serious about their photography. For those that are new it will answer some common questions. Thanks.
Using the title of the video, I found this upload straight away. Can anyone confirm that it's the same as the one originally linked to by Polyglot? I bookmarked it at the time, but don't recall getting around to watching it.
I've just checked through old hard drive catalogues and found that I had downloaded the file from the original link (don't laugh, I only had dial up internet at the time and couldn't watch YouTube videos any other way). At any rate, I can confirm that the link below leads to the same documentary as the one linked to by Polyglot a decade ago.
Here's the link to "The Alchemist in Hollywood" newly uploaded a year ago :
