Quote: Javaslinger K20D digital preview?
--------------------------------------------------------------------------------
What exactly is the point of this? As I see it, it essentially takes a picture - and just doesn't save it.....
Why not just take a picture? It's not like space is an issue these days....
What am I missing?
Thanks,
Ken
It is a great feature which allows you to obtain correct exposure more easily. This is very important with some of the older lenses which do not meter so easily on Pentax DSLRs. The histogram shows you just how close, or far away, you are from getting the exposure you desire.
It does not save the shot, because the odds are it is not a keeper--it is just a shot to get you in the ballpark. But, if you happen to hit the perfect exposure by chance, you have the option to save the shot.
It is a lot like the "Preview Post" feature you use to "post" a reply--right? You can look at your writing, to verify its accuracy, without yet saving it to the forum--make sense?
Others here may be able to provide even more information on this useful feature. Best of luck.
