Re: Re[4]: Wireless flash and off camera clips, grips, pips, tips, salsa dips

There is just no good automagic way of doing multiple, off camera flashes.
With studio flashes you: get a meter, use a digital camera (even a PS) to
check a histogram (you can check this with a PS by uploading the file into
PS), or shoot many, many rolls of film. If your shooting a subject, and want
a 1:3 lighting ratio (1.5 stop difference) from one side to the other, TTL
won't work. Your better off using both flashes in Auto mode, and set them to
give different amounts of light. If I was shooting a person and given the
choice between: two independently controlled lights (say into umbrellas),
one light and fill card, one light and one light with on camera fill flash;
the on camera light would be last and I wouldn't bother with it.
You can do studio lighting on the cheap, but there are certain basic
capabilities you need to get decent results.

Could you please explain this further.  I had actually planned on the slave
providing most of the light and the popup or hotshoe mounted flash providing
the minority of the light.  I'm afraid I'm still a bit lost here.  I have
the PZ-1p and PZ-1 cameras at this point and have no wireless to play with
as yet in my Pentax equipment.  I also have acquired a professional stand
type modeling flash with 3 variing outputs from a local photographer that
retired, only $40, and of course would like to implement it.  Unfortunately
I do not possess any metering equipment other then on camera metering.  I
have the AF360FGZ and a couple of other off brand flashes for pentax.  one
of which supports TTL and AF.  I had planned to use a minisoftbox on my
hotshoe on camera flash with the slaves.

Dave,

You are basically correct if the popup flash is stronger than the
slave and ambient isn't too strong.  The problem is, that the reason
to move the flash off camera is to make the main light not be direct.
 In your proposed approach, the popup becomes the main and the
 AF360FGZ becomes the fill.  The desired lighting effect is probably
 not really what you are looking for.  You either need something to
 control TTL on all flashes, including ratios or run all the lights
 manually and flash meter for correct exposure.

DM I also am very interested in this use of slave flash.  I would have expected
DM the TTL functions to operate normally on the camera for not only the onboard
DM or external mounted flash but also for the slave flash.  If you set the
DM slave for less then you expect to need  1/16 etc, then the on camera flash
DM would make up the difference wouldn't it?  It would read the total provided
DM light from both flashes via TTL and provide the necessary amount on the on
DM camera flash to provide correct exposure.

DM I'm not saying I know this to be true, but rather pose this as a question.

 No TTL that way.  You must manually set flash output and probably
 meter manually.  Also need to take into account the popup flash on the
 MZ-5n.

 If you want off camera flash and TTL, you are going to need cords and
 connectors from Pentax.
