ps, how can I start a mosaic pano where the first picture is straight up and after that it starts rotating around the yaw with a lower pitch?

Thanks!

In Mosaic mode Papywizard can only shoot a regular grid/matrix with the same number of images in each row. This mode is designed for shooting partial panos - panos with a pano FOV of less than 360x180.

If you want some irregular pattern then you will need to create a custom preset and shoot in Preset mode, this mode is designed principally for shooting sphreical panos with a pano FOV of 360x180, but it can be used to shoot non-spehrical panos too.

You will find information about custom presets here:

Hi all, a quick question about the camera settings.

Here I found the values I think are needed for papywizard:
http://www.adorama.com/alc/0008638/arti … ser-report

Canon G10
Sensor coef = 4.5
Ratio = 4:3
Sensor res = 14.7
Lens type = rectilinear
focal = 28mm (when completely zoomed out)
optical multiplier = 1

*Is sensor coef indeed the same as the focal length multiplier?
*When I do want to zoom with my G10, do I need to both change focal and the optical multiplier?

Please have a look on the next "complete specs" from DPREVIEW
http://www.dpreview.com/products/canon/ … /canon_g10

@mediavets, the value 4.5 can be found in the link provided.
@claudevh, the focal length is already set at 28 in papywizard.

So what exactly is the sensor coef? It cannot be 1.7 I guess, that would be too simple.

*When I do want to zoom with my G10, do I need to both change focal and the optical multiplier?

Thanks for the help so far, great community!

Hi Robert,


You should set the optical multiplier to "1.0"
You should set the objective to "rectilinear" and "28 mm"

I suggest that you use the "preset mode"

The "optical multiplier" is just if you are using a Optical accessory to increase or decrease the focal lenght of your objective !

The "sensor coefficient" could be set to "1"and  the "sensor ratio to "4:3, 3:2 or  16:9  this is the choice you can made in the G10 menu.
Those parameters are usefull only if you use the  to "Mosaic mode" who will calculate the pixel size (just informative!) of the resulting panorama.

You can find a XML preset herafter (please save as XML file in UTF 8

I ahve send the Preset by Email in the right format !

The Preset has been send in the right format, just load it in Papywizard and use it !!!

Since your Canon G10 already assigns 35mm equiv. values to focal length indicators on the camera then I believe you should set the sensor coeff. to 1.

Most of the time when I look at the details of a picture I took, I see focal length values of 6 (most common), 14, 16 and sometimes 21mm (depends on the zoom, most of the pictures are taken on auto mode). Does that mean my G10 assigns 35mm equiv. values?

Because, when I use my render program and I set the virtual camera to the same value as the picture, the 3d object looks very distorted. (using my picture as a backplate, I can add 3d objects on a location). However, if I multiply this value (let's say 6mm) with 4.5 (or 5) I get 27/28mm which makes the model look perfect in the perspective aspect.

The camera is marked - I presume there are markings on the lens but maybe not? - at 35mm equiv focal lengths which take into account the 4.5 sensor coeff. (aka crop factor).

But the EXIF data probably records the actual focal length - ie. 35mm equiv/4.5.

In Papywizard set the 35mm equiv. focal length - if that's what's indicated on the camera lens - and set sensor coeff. to 1.

Then values you set in stitching software are another matter especially if you pre-process the images and in doing so strip the EXIF data from the images.

What stitching software are you using?

The values I gave are from the EXIF data. does that mean that every FL value has to be multiplied with 4.5 to see the 35mm equivalent value (28mm for example)?

I use autopano and ptgui.

Ok the setup is working fine, now I have another problem.

When I try to bracket shoot, the pano moves the camera before it is finished. Using the bracketing option doesn't work, because the panogear just presses the shoot button 3 times (or more, depending on the setting). The g10 simply takes the bracket shots after eachother. Is there no simple way to just say, wait for 2 seconds before moving to the next position? This is the Nokia N810 papywizard.

(edit)
Ok, solved this, using "Time value".

1 other small problem, the mosaic always starts at the bottom left. but the camera points to the top left. I cannot switch the camera because then the nodal point would be off. Furthermore, the knob/stick for tightening the camera holder points to the right correction (bottom left) but why choose the side where a stick is sticking out as the main direction?

This could be changed in "Configuration/Mosaic/Start position"

On the N810 I have the following options, overlap, start from, initial direction and CR.

changing "start from" lets the pano start in the upper right corner. (but then my camera points to the ground). Of course this is something I can live with. It would be nice if I could make papywizard clear that my camera is mounted the other way.

Hi Klausesser,

Well, no actually.

I have mouted it exactly like this one:


So with the handle to fasten the L shaped camera mount pointing to the other direction.

Ok, a big problem. I cannot get the canon in it's nodal point. When using the L bracket my camera sits to far to the right (let's call that the X-axis). The Y-axis is not adjustable. And the Z-axis is.



I know now why the pitch is reversed. I simply cannot turn my camera, as it would bring the nodal point of the camera even further from the nodal point of the pano gear.



In this situation the X axis is ok/best, but the Z-axis is not adjustable and wrong.

The only solution that would have worked, has an edge which sticks out.

Would it be possible to buy this part somewhere without the edge?

And last, because the Y axis is fixed, can I really get the nodal point?
