[Leica] Now RAW vs JPEG

WOW!!!!!!!!! :-)

Now I gotta tell you, you folks are beginning to scare the daylights out of 
me with all this stuff!! Heck I may just have to keep all my film cameras 
after all and return to Mother Nature film! ;-)

Well I hadn't really left it, as it's part of me and breathing! :-) So I 
still always have a film camera in the bag and rolls of film. I mean if I 
didn't I'd surely be struck down by a mighty sword of wrath from the Great 
Film Father in the sky! ;-)

It sure is beginning to look like film was much easier, at least I knew what 
the heck I was doing. OK, OK most of the time. ;-)

But all this stuff is near scaring me off because it works like this:

"Tell me and I will forget.
Show me and I may remember.
Involve me and I will understand!"

But I have to add... "Confuse me and I'm dead in the water!" :-(
