Question: Do any of the digital cameras offer the instant shutter of my old Minolta SLR? This delay is one of the most annoying things ever.
There was a big stink about the impermanence of the color from the prints from the first generation or two of Epson Photo inkjet printers. Users (such as myself) noticed prints going yellow with age. Some of them documented their experience and eventually Epson took notice of the bad press and set about to solve the problem. They commissioned an independent testing lab to test their old and newer inks, and began to publish results on the permanence of the prints from their newer inks and papers. Various theories on the degradation mechanism have been propounded, including UV (the classic mechanism for all color materials) and Ozone.
There is a distinction between the two basic types of inkjet inks: One is dye-based, and the other is pigment-based. Pigment based inks are more color stable, it is said, but are more expensive and difficult to accommodate in an inkjet system; until recently, they tended to exhibit a slightly smaller color gamut also. If you look at the current Epson line, you can see a distinct price division between the dye-based and pigment-based inkjet photo printers.
