Wahay! jackpot!
Big thanks Don.
Think I'll save this link, as it'll prove useful when I'm in experimentation mode.
On another tangent, one day I might even find some old stock Technical pan to go the opposite way with....smooth creamy mono tones....some of my most favourite hollywood star images were taken using that stuff....it was rare when I first got into photography....it'll probably be easier to find Lord Luncan or Elvis, but we shall see!
