Andrew, no, the shutter is triggered *after* the stabilization delay (and during the same delay, if the mirror lockup feature is activated). Then, the shutter is triggered during the 'time value' param. And the complete sequence starts again for bracketing. As we didn't move, we just launch the mirror lockup feature immediatly.

It is possible to activate the multi-shots program, with the bracketing, so, by holding down the shutter button, the n bracketed pictures are taken. So, you can just give a 'time value' long enough to complete this sequence. But it is not a good idea, as only 1 shot will be recorded in the xml data file.

For the rest, your description is ok.

bigwade, I'm looking for a solution to create a documentation which can be on the wiki, as pdf or html, and which can be embedded in Papywizard, so you can read the manual on the field.

You can try this tool, to make a pdf from the Papywizard wiki:

Just give the wiki page...

Frederic,

Yes, I know the shutter is triggered after the Stabilization delay (if no Mirror lockup is set).

What I'm trying to get at is precisely when - in relation to start of Stabilization delay interval and before shutter is triggered by second closure of the contact switch - the switch contact is closed to invoke miror lockup if mirror lock up is set.

I don't have a camera with mirror lockup capability so I don't know how it works when a users operates the camera manually - perhaps you can explain that too - does the user have to press the shutter button twice when using mirror lockup?

If my camera had mirror lock up I could check experimentally how it operates under Papywizard control - but I can't - and I wish to document some of this for others - that's why I want to understand it and get a complete and accurate description.

My Nikon D40 doesn't have AEB either (nor does the D40X or D60). Do all DSLRs with AEB allow the user to chose whether to use one shutter press or multiple shutter presses when using AEB?

Klaus,

Here's what I see when experimenting - in this instance it's helpful to have an IR LED shutter trigger because I can watch the LED flash.

Hi Andrew!

Thanks for your explanation! I didn´t look close enough to the whole thing - was a bit in a hurry these days . .
Where would i be without yours and Freds help . . .

best to you, Klaus

I set a mosaic this way:

3x2 pictures bracketed
stab delay 0,5 sec.
TimeValue 10.0
Mirror lockup

Camera was set to -2/0/+2
"center time" was 3 sec.

problem: the camera started the 2nd picture before the head moved to the 2nd position . .

"effektive" exposure-times are:
0,75/3/12sec. That means that the head should have moved BEFORE the 2nd picture before the camera should have been fired.

I set time value to 12. Now it fits. head moves only after camera shot the last picture (12sec) of the bracket-set.

BUT: Papy waits 12sec at ALL exposure-times. That means it waits 12 sec even after the 0,75sec bracket before it fires the 3sec bracket. Then waits 12sec before shooting the 12sec bracket, then waits 12 sec before moving to the next position . . (wich is correct)

Seems to be no way to change that behaviour. It would be fine if it could match the time-value to the real exposure time. As an example Tv could be x% of the real exposure time at the bracket exposure.

So when you shoot a 3/6/12 set time-value would be 3,5/6,5/12,5sec before the next shutter-release resp. move to the next position . . . ? While stab-delay always is 0,5sec. after each mirror-lockup.


Waiting 12 secs. after shooting a 0,75sec bracket and a 3sec bracket wastes much time . . .

Andrew, yes, when you set the mirror lockup, you have to trigger the shutter twice. That is what Papywizar does. The first trigger duration (to lockup the mirror) is 'stab. delay', the second is 'time value'. In fact, we should need just a pulse, then wait stab delay, then another pulse, then wait 'time value' delay. But I don't know what value to put for the pusle; it will depend on cameras, I guess. Si, I put the pulse equal as the delays...

I will try to make a chronogram...

Chronogram would be useful. Thanks.

What do you think of merging the initial stabilization delay after moving and the mirror-lockup? It think we can immediatly launch the mirror lock-up sequence (if activated), which will be atcivated for that stabilization delay. I don't see any point to wait for the stabilization, then shake again the camera with the mirror, and wait again...

If lockup-mirror is not activated, we just wait the normal stabilization delay... If OK, I can include this in the next minor 1.6.x release...

Sounds very sensible to me.

1.6.1 and earlier bug: can't set FL less than 10mm, but my zoom kit is 9-18mm

Is it a rectilinear lens, or a fisheye?

It's the Zuiko Digital 9-19mm rectilinear.

I removed the 3D simulator... Too much things to maintain.
