Re: Manual flash contol on Pentax DSLRS?
If there's no external flash used, the on-camera flash compensation WILL change integrated flash output on my K10D. If an external flash is used as well as the integrated flash: not sure about FEC but contrast control works well :) On Tue, Jun 3, 2008 at 6:18 AM, Adam Maas [EMAIL PROTECTED] wrote: Manual flash control on the popup is not available on any Pentax DSLR.

Re: Manual flash contol on Pentax DSLRS?
Contrast Controll, what and how is that? I know it is a way to ballanse the output of two or more flashes. Is it a Wireless alone feature? Or can it also be used in cabled setups? Is it controlled by P-TTL or can you use it in automode? I have thousands of questions :-) MaritimTim 2008/6/3 Thibouille [EMAIL PROTECTED]: If there's no external flash used, the on-camera flash compensation WILL change integrated flash output on my K10D.

Re: Manual flash contol on Pentax DSLRS?
OK will try to remember as much as I can. First, contrast control was introduced with Z-serie (SF?) cameras which did have the ability (which I miss a lot) to use external flash as well as integrated flash (wireless didn't exist at that time). So it worked already in the TTL era. It still does work however. With two flashes (More, I dunno) which were as I said the integrated flash and the external one, using contrastcontrol will do the following: * balance the output power of both flash so 1/3rd the light comes from the integrated flash and 2/3rd from the external flash. * lower max sync speed because of the process of syncing those. In fact the major use of it was when you bounce the external flash and usse the integrated one to bust shadows. In my experience it worked pretty well, even with compatible flashes as Metz MZ flashes. I dunno the implications of using this in wireless mode with more than 2 flashes however or if it is still possible at all. Maybe only in wired mode with deported flash. BTW, I checked yesterday and indeed my K10D integrated flash reacts pretty well to the flash exposure compensation set on the camera. Exposure settings did not move but flash power did, and the result was very noticeable between -1 and +1. I think this is all. Feel free to ask for more :) -- Thibault Massart aka Thibouille -- Photo: K10D,Z1,SuperA,KX,MX, P30t and KR-10x ;) ...

Re: Manual flash contol on Pentax DSLRS?
Further to what was said: The two flasguns were triggered at a different moment in time, one at the leading edge of the sync pulse and the second at the trailing edge (this is in fact rear curtain sync) In this way the light output of each gun could be measured and controlled independently. Example if the main flash came from the side of a model, the shadow side could be too dark, too much contrast. The second flash (maybe on the camera) could bring just a bit of light in the dark parts to get a contrast that could be handled by the film. On the PZ-1, I created contrast control with 30 year old automatic flashes, one triggered at the leading edge and one triggered with the trailing edge. I only had to make a little circuit for one flash to surpress the leading edge and to invert the trailing edge to get rear curtain sync. One of these days I should check if my K10D allows the same trick. If I only had time... Greetz, Jos Thibouille wrote: OK will try to remember as much as I can.

Re: Manual flash contol on Pentax DSLRS?
Thank you to all three of you. Sounds like something useful. I think it can be useful with on camera flash and the 540 mounted at a flash bracket. I have finally decided what I'll buy, one 540 (maybe a 360, or another 540 later), a short cable, a Better Beamer for birding, and a Lumiquest bounce kit for regular flash photography.

Re: Manual flash contol on Pentax DSLRS?
That's pretty much my flash kit: a 540, a Kirk flash Xtender and the lumiquest bounce kit. I also have the lumiquest soft box attachment. That can be useful where reflectors don't give you enough pop. Paul -- Original message -- From: Tim Ãsleby [EMAIL PROTECTED] Thank you to all three of you. Sounds like something useful.
