Just found out you can set the 20D to do this for you by going to custom functions in the menu area and selecting C-FN-02. Page 141 of the manual in Custom Settings. Probably best to try this and the PS way see which gives the best results. Message edited on: 07/04/2005 06:43

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.
