Anyone knows what is the difference between the premium and standard colour hardcover versions? Price-wise, there is a $35+ gap which is quite significant considering if the content are the same (by the way, I am already a subscriber to the PDF - just wanted to buy the hardcover print book)
The difference is paper quality and print quality. Personally, I can see the difference clearly - sharper images with clearer colours (and the difference in paper quality makes for a physically thicker book). The standard is still gorgeous; the premium is just a bit nicer.
