From what I gather looking on the web (it's difficult to fathom on the Metz), if you have the correct Pentax SCA-3702 adapter for the Metz, then you should have rear-curtain sync (perhaps called "2nd Curtain Sync" available as a little switch behind the window of the SCA adapter

If you're still stuck, then I have an SCA3702 at home - I can tell you what to look for, but from memory, the far left position is 1st curtain sync (leading curtain sync), the second position has two green triangles, and the third has a green triangle/flash - which is the rear-curtain sync.

HTH!

Examples of the slow shutter speed, rear-curtain sync:

David,
Not sure if this is what you want...
Perhaps you could try rear-curtain sync and a slow shutter speed.

Like this:
* Set the flash and camera on a tripod
* Set rear-curtain sync
* Set flash to manual
* Set aperture to, say, f8, shutter speed 1/30s

The flash will "freeze" the motion of the items being juggled, but if you balance the ambient light (along with aperture and shutter speed) right you'll see a trail of their path.

To get the appearance of multiple items you'll need strobe flash along with the above technique. Some of the Metz guns will do this (my 50MZ5 will), and (I think) the Pentax AF500-FTZ.

Far easier is Photoshop (or Elements even):
* Take two shots (as above) in quick succession
* Open both shots in PS
* Pick the move tool and drag one shot over the other - this should make one the images have two layers (you can also use Ctrl-A to select all, Ctrl-C to copy, switch to the other image and Ctrl-V to paste)
* Open the layers tool so you can see the layers
* On the top one, change the layer blend mode from "Normal" to "Screen" (assuming you have a black background in the juggling scenes)
* Now you can erase what you don't want in the top layer.

(It's far easier to show this technique, than write it Check out the layer tutorials on my site: www.mattmatic.co.uk which should get you familiar with the basic terminology and way of working)

Have fun!
Matt

BTW, the actual problem was the "Shadow" warning on Adobe Camera RAW showing all the dark regions in blue

(Conversely, the "Highlight" warning will show in red.)

As Kevin said, problem sorted
Matt

P.S. John - I've edited your comment (you'd use the "Code" button by mistake!)

LOL @ Tim (Flattery will get you everywhere )

Don - I've been looking at the RAW file. It's not hot/stuck pixels. Kevin had accidentally pushed the exposure by 2 stops which had created an overexposed image, and the blue (from the water) seems to be "bleeding" through onto the foliage because of its luminance. There's perhaps a touch of CA in the image, but nothing really glaring.
Just confirming though...

FWIW, it's always worth checking your histogram to make sure the graph tails off before it hits the right hand side, especially when shooting RAW. You can always correct slight underexposure with RAW, but you can't do much for over-exposure! (And in general, the Pentax exposure system is excellent!)

Matt

Kevin,
I've sent you a PM (private message) - I'll check out your RAW file if you want and let you know what's happening
Matt

If you mean a very blue single dot (or very green) then this is probably a "stuck" pixel. You should find they always appear in exactly the same place on each image.

The RAW convertor should detect these and remove them, but in the preview you'll probably still see them. (I have quite a few on my ageing *ist-D and more when I use higher ISO settings).

Hi Henry!
This has been covered (many times) before:
https://www.pentaxuser.com/forum/viewtopic.php?t=2970

The answer is basically "yes", with some provisos
Matt

Great result Brian

I'd converted the image into pure B&W, FWIW, which is why the colour looked "wrong" for the moon. Must try harder next time

Matt

Fine image Brian... just applied a little bit of Photoshop processing:
