Originally posted by Bcrary3 I personally have never worked with either camera, however, on the K-5 (which may be similar to the K-3) I simply set up a user profile for HDR taking photos at -1ev 0ev and +1ev
I imagine the K-3 has a similar ability, and you can tweak the EV steps to get the result you want. I think you can go more than 3 steppes too. If I remember correctly the K-5 may be able to do 5ev steppes for HDR, not sure though. The K-3 probably has a pretty similar function. Not sure if that helps or not. Someone else may be able to answer better than I.
Both the K-3 and K-5 can do 5EV step brackets. E.g. -2, -1, 0, +1, +2
