Re: Photographic primers?

Hi Mark,

All of it will will be of help to him as he gets into the literature and begins 
to 
understand the basics. Then your words will become understandable to him 
and real progress will be underway. 

He's a conscientious guy, and will make the effort, I believe. He'll likely 
store 
your words until he has the groundwork established in his head. Thanks for 
the good advice.
