I apologize for re-posting, Smooth.

Thanks to John Houghton for his careful observation. I find out the visual centre by the electronic viewfinder isn't the real centre when it comes to PTGui stitching.
After a number of adjustments, I finally nailed it. There is a shift of 5mm to the side for my system. I have re-posted another 2 sets of images for your perusal.

Here is the nadir and zenith of the set after the adjustment


Thanks again.

These are the results from an Automatic stitch of 4 rotational shots +3.5° tilt up. Nothing but remove worst control points (Ctrl+Shift+W).

I don't need to close crop or change projection. PTGui handles the images fine. What you must do it shoot and process the images correctly and have the NPP dialed in.

Peter, your Nadir footprint (NPP) looks much better now and your images should stitch somewhat easier.

Thanks, Smooth, for your advice and the .pts file. It is amazing that you can generate these very good and tight control points. I will spend some time to study it.
To be able to stitch directly from the originals rather than the remaps will certainly guarantee better quality.

A fortnight ago, when I first got the Madoka 180 I was puzzled and dissapointed. Now, I begin to like it.

Here is one of my exercises with in-camera HDR and Madoka 180.
I am still unable to stitch images straight out from the camera like John Houghton and Smooth can. (I am still trying though.)
The location is 'Hong Kong Institute of Education' in Taipo, HK.
The first set: Madoka06-10 is the copy of the original.
The second set: shot06-10 is the quasi-stereographic remaps

Hi Peter,

Here is my .pts file from your latest offering.
www.omnipix.net/temp/madoka06_smooth.zip

It was NOT and automatic stitch.
I wonder if you have picked the best way to use and shoot with your Madoka 180? You certainly are not processing the images to get their full advantage.

I ask this based on the following:

The Chromatic Aberration is pretty noticeable on the extremities and it is these extremities you need to place control points on.

I suggest you shoot 5 (or 6) rotational shots with slight tilt up (say +5°) there is no real reason to shoot a separate Zenith (unless you have something very detailed above).

It is vital you either shoot RAW or at least open the .jpg in Bridge/ACR and process/develop the images to remove the imperfections like Chromatic Aberrations before "expecting" PTGui to automatcially stitch.

The cleaner and sharper the images the better chance the automatic control point placement will be.

Hi Smooth,

I will definitely learn to remove Chromatic Aberration from the images.
Thanks for the tips.

"it is a pity they didn't allow for adaptation to M43. I have one, there is no simple way to cut out 2mm flange distance for M43. But it can be adapted to Nikon 1.
Nick"


That´s not correct. just a matter of adjustment - and another mount, of course...

Could you please lighten up the image? I cannot make out any detail, only an the camera make and model. I cannot see how the lens is attached. Thanks.

Another dark picture taken from a different angle. Still cannot see detail. Why must you have everything so dark? Take your camera outside and shoot it with some proper lighting. The artsy-fartsy stuff is for magazines, not for showing how something is put together.

Ok, I have to find details for you. Maybe a view through the Madoka helps for the moment... smile

I am beginning to think you do not own the camera/lens but are posting pictures you find on the internet.

When I finally figured out how to mount a laser pointer on my camera, here is the picture I provided to show how I did it:


Image shot out doors with a whole lot of light showing all the details without leaving any question as to what you were looking at. You can clearly see all the parts and how they are assembled

This is the type of picture I am requesting.

Don´t believe everything you think, DennisS
