I didn't even know what "chimping"is - had to look it up.
Well, back in film days there was no such thing - so I didn't.
I started with Digital Photography back when a 640x480 P&S was $249 and considered "high end". You had to "chimp" because memory cards were very expensive, small and filled quickly. Reviewing photos was a must.
I still do during times I'm not shooting - might as well get rid of the bad photos instead of doing at home on the computer.
If things are too hectic, it can wait now (when a 4Gig CF card can hold 300 photos in RAW... :eek
Nowadays, with cards so large and cheap, easier to wait and possible not miss the shot.
I don't see why if a person "chimps" - they're not as good a photographer...
