Good Morning,
I do not have a K3, but from the manual it appears that it operates just like my K5 (but with more options to select from) and I use bracketing all the time.
- Press the ^ key from the 4 way controller (item #25 from page 8) - this will bring up a menu at the top of the monitor with a number of selection icons. The camera is currently in bracketing mode, so the bracketing mode icon will be selected/highlighted.
- To move to another mode - lets say single frame shooting (which would be the first icon on the line of icons on the screen). Use the < or > to move the "selected icon" or "highlighting" so that the first icon - the single frame shooting icon is selected or highlighted.
- Then press the OK button to select the single frame shooting icon.
- You are now in single frame shooting mode
hope that helps....
PS - its nice to come across another Gordon on the forum!
