I don't know the technical details. But, I am blown away by the colour quality of those slides.
I know! You should have seen my face when they came up on the screen for the first time.
The photographer knew what he was doing.
What is sad, is the amount of slides that end up being binned, because people don't realise that they can deliver results like this.
I keep meaning to put an advert in the various newspapers here asking if anyone else has early QE2 slides.
