The result from my search on the Noel Leeming website ......(I think I was being too specific ! )

Its taken with a Pentax camera / Pentax Lens / Pentax Flash .... its the equipment obviously!! Thanks for your comment .....

Thankyou, I hope you found the explanation helpful.

It's just exploring possibilities, some things to focus on and try and see if they solve the problem. As I understand it the switching into HSS and out again is automatic with the Cactus triggers, but the communication can still be lost if there's a time out between shots. The half press of the shutter us just a way of being sure that the circuits are active again before taking a shot.

You might do better asking on the Cactus Community Forum ....but you will get the same questions about very detailed info on your set up and and modes and everything. Anything that's unsure will prevent any real conclusive diagnosis. But good luck, let's hope it works better next time.

By the way, that XTTL firmware is getting closer for Pentax I think .....

Only if it feels like being stuck I imagine .... I'm stuck with Pentax but it doesn't feel like being stuck, so it's a good thing

Yes, but this time the cycle has come round right for him .... He'll be stuck with Pentax!

Thank you David, I'm pleased you saw the photo

It's very easy when in the heat and buzz of a real off site shooting situation, to lose the method and careful approach that we use at home and when testing things. Frustration kicks in and we might not notice something .... It's happened to every wireless/radio flash user!

I know the Cactus triggers can lose their communication with the camera and flash, and this also occurs if the shutter speed jumps below and above the max sync speed ..... The system needs to be "told" again to change it's sync mode signal. The way to do this is to half press the shutter button, even if not focusing, to reactivate the circuits before taking the picture. ...

If when using P or Auto modes (not recommended) then it's possible the shutter speed moved around without you noticing, perhaps causing the loss of communication, and needing the half press on the shutter again each time. It's something to be aware of and try out.

Thanks Ian and Philip.

I've taken the suggestion from Philip and made a levels layer adjustment to bring the black point up on the background and remove the pattern coming through the curtains .... I like it better! Thanks Philip and Claudia for prompting the extra work .... well worth it

No 3 and No 8 stand out .....3 gives a superb sense of the space with it's depth and glimpses into the other areas from the left and right sides of the frame. No8 has the curve of the conductors arm matching the patterns behind him ....all rather decisive momenterish !
