Thx Michelle & Misha - that explains why I didn't think the curve I was given was working.
The curve does one thing the text says another.
Hmmm interesting .........
Have to look at toning again when it's a rainy day. I learned quite a bit from that even though it wasn't how to make a selenium tone image :) Oh hang on I did learn that too - just didn't think I did and thx again cos I learned it was suppose to look purplish :) Message edited on: 04/21/2005 03:55

And every one said, 'If we only live,
We too will go to sea in a Sieve,---
To the hills of the Chankly Bore!'
Far and few, far and few, Are the lands where the Jumblies live;
Their heads are green, and their hands are blue, And they went to sea in a Sieve.
