i did read the manual about TTL passthrough and was a little confused. So the "passthrough" only affects the on camera flash? So i could in theory use the on camera flash in P-TTL even though the off camera ones were in manual ?
I will give it all a try at any rate. Thanks again

I have tried the flash mounted on top of the Cactus TX on the camera but a practical issue arose which caused me to ditch the idea pretty quickly. With the flash fitted with a gary fong diffuser the weight was causing a slight wobble despite everything being locked down tight. This would lead to the TX unit losing contact and not triggering at all at times. I will try again at some point with another of the units as TX and seeif it makes a difference.
About TTL Passthrough.....what would be the advantage of using that mode rather than manual on the on-camera flash?

Would it not work if all three flashes are set to manual - so no pre-flash? Then just set the power output on each to get the effect you want.
Yes that would work if i were not using radio triggers. The Cactus triggers require the flash units it is controling to be set to P-TTL, even though I am using manual control for them.
I am finding the convenience of being able to change individual power settings and zoom settings from my shooting position via the Tx unit to be much more convenient than having to change settings on the flashes themselves. So my only option is to get another trigger if I want to use three flashes and keep radio control.

So I guess I am seeing its flash before the mirror lifts. Oh well if I want to use three flashes I shall have to get another Cactus trigger. Getting expensive this flash malarky! But I am really enjoying the new adventure.

I have two AF 540 II units and one AF 360 unit. I have three Cactus V6II triggers. The 540s are triggered by a Cactus V6II each in Rec mode and the third V6II is in Tx mode on the camera hotshoe.
The AF360 i have set to Manual mode and set the slave mode to "2". When i take a picture all three units fire, but the AF360 is not adding any light to the picture. I can see its light output on the subject through the viewfinder as I take the picture so it seems to me it must be triggering very late and the mirror has already returned by the time it is providing its flash.
Anyone else experienced a similar problem when using a mix of radio triggers and "dumb flash mode 2"
I am using Manual mode on my K1, 1/180 f11. The two AF540s are set in normal P-TTL mode (as per the Cactus manual for the triggers). The AF360 is set to Wireless slave mode; Slave mode 2; and manual exposure flash output.

I have the K1 which also has no built in flash, and I cannot say I miss it.

I dont have a white background so I lightened the grey one in Photoshop Elements using the dodge tool. This has probably led to some degrading of the image round the periphery of the subject, but until I get a white background is the best I can do.
I have started using the camera on a tripod triggered by remote so as to give me more control over the subject.
