Please help me:-) How is this possible?
I am still learning about my K-3, and the fitures this camera is in possessions of. But I do not understand why it is posible to use the flash up to @ 1/1250 sec in "HDR" mode. (HDRauto and HDR +/- 3EV. - Absolutly NOT +/- 1EV and not +/- 2EV.)
My flash is YONGNUO YN560 IV and trigger YN560-TX or an old Jessop 300AFDP and trigger RF603N II from YONGNUO. In HDR mode, it is not posible to set flash functions in any way. Usually max shutter speed is 1/180 sec with my flash.
My setup: K-3 @ HDRauto, Shutter speed 1/1250sec, aperture F18 and ISO value to 800. Moreover, I have set YN560 IV @ 1/4 Output Power. I can see differense in exposure if power output on YN560 is set at 1/8 and 1/2.
I had taken three different photo with the same aperture setting, and the same ISO value. Shuter speed varies only in one case, from 1/1250 to 1/160
There are three Foto's.
The first is with Shuter speed 1/160 and flash. HDR = off.
The second is the shutter speed 1/1250 and flash. HDRauto = on.
The third is with shutter speed 1/1250 and no flash. HDRauto = on.

If you is using the flash in slave mode, then set k-3 in manual flash mode, and the popup flash power to 1/128, or you can do the same as I did, by an Yongnuo YN560-TX...... I LOVE IT :-)
