Hi Peter,
Thanks for your guidance as well. Great points, you are correct on the shutter speed maximum on the K3II.
Makes sense on the distance to travel for the light when bouncing. I have gone that route because I found the direct flash to be very harsh, creating some shadows and blown out subjects, but in that I realize that is why you and Clackers are suggesting lower power (1/8) on the flash in manual to dial back how impactful the flash will be (I think).
Thanks again. Cheers.

Thank you Clackers, great info!
The shutter speed is 1/180 maximum for leading curtain and contrast control, and 1/90 for trailing curtain. I believe a limitation of the specific camera?! And I agree I'd much rather stay faster especially with a son who loves to move without warning :) That is why I have the ISO as high as I do.
One item I'd like to learn is how to light just the subject, and have the background just be dark or dim.

Great thanks guys. I guess one thing I didn't consider is that when I shoot in manual I leave the flash in auto, but the results aren't as consistent or easy to control.
So there is another curiosity. When the camera is in manual but the flash is in Digital P-TTL is the flash still reading the ambient light and camera setting and adjusting?
I ask because as I said above, in manual it is just not as consistent, which I understand is the case likely do to the photographer mostly.

Just doesn't seem to give as good a result is what I'm saying.

Greetings,
As a former K20D and now K3II user I have learned the ins and outs of shooting manual and am quite good but by no means a master/pro etc. As a new father I find many great opportunities to use my camera, and most of the time it is in manual.
Indoors to supplement the lack of decent lighting I'll bounce a flash off a wall attached to the hot shoe, again most of the time using manual program line on the K3II. Today I used the program mode and something confused me I wanted to ask this great group about...
One shot - 1/80 F2.8 ISO 800
Other shot - 1/100 F6.3 ISO 800
Both shot in program line mode with the flash on P-TTL Digital, auto zoom. Flash is a Pentax AF-540FGZ from around 8 years ago or so.
So my question is: does the flash perform its own calculations and fire at the power it is required based on the lighting and camera settings for each shot (when in a more auto mode like Program Line)? Because with a faster shutter and smaller aperture on the second shot the exposure is super close (slightly different scene).
ie: First shot, sensor/camera saw more light from the slower shutter and faster aperture so the flash didn't shoot as bright, but on the second it saw a faster shutter, more narrow aperture and (the flash) increased its output on its own?
I think I was expecting the camera to adjust the aperture if I moved the shutter speed, and the shutter speed if I adjusted the aperture. However it wasn't the case I adjusted both and the ISO remained static.
Thanks in advance all. Appreciate any thoughts or guidance.
Shane
