But the D70s does have mirror lock-up! See page 162 of your manual: "Highlight Mirror lock-up in the
setup menu ( 155) and press the multi selector
to the right. Press the multi selector up or down
to highlight an option, then press to the right to
make a selection."

DorinDXN said: the number of photos must be around 10-12 for each pano to have a distributed parallax
Hi Dorin,
Great experiment! I am going to try one of those myself, but why exactly does the number of photo's have to be 10-12? Would this mean that with my Nikkor 10.5mm (I normally shoot 6 photos around + zenith + nadir) I would need about 20 photo's?
And how do you synchronize the two panoramas for viewing? I haven't used the cross-eye technique yet myself, but I have made anaglyphs before (both with a sliding bar and with a Loreo lens). Which is nice, only you need cyan-magenta coloured glasses.

Nice panorama's. I wonder what your home made bracket for the off center nadir shots looks like.

John Houghton said: A few intelligently placed control points can make all the difference.
You're right. PTGui gives me full control where APP doesn't allow me to place single control points; it always wants to do a geometrical calculation. Still, wouldn't it be nice to have a program that has the best of both worlds (PTGuis flexibility, speed and control, APP's ability to match surfaces with no visible control points, read NEFs and an easy, intuitive perspective control for vertical lines).

John Houghton said: Pierre, And have you tried stitching with PTGui Pro using the Viewpoint feature?
To be honest, I didn't know about the viewpoint feature yet so I downloaded PTGui 7.6 trial just now and the results (with viewpoint correction switched on in the optimizer tab but no manually added control points, because that is exactly what I want to avoid) are better then above. See below. Actually, the results with Autopano Pro and PTGui are not that different anymore. Still, I have not made up my mind yet. PTGui is much faster. Autopano Pro reads my NEF (Nikon raw) files directly and has a more intuitive interface. It also stitches surfaces where PTgui can find no control points at all.

How about this for comparison.
The first picture is cubeface 5 from a panorama stitched with PTGui (without manual editing):
The second picture is the same cubeface from a panorama stitched with APP (again, without manual editing). This is also not perfect, but there are noticeably less errors:

Maybe it just seems sharper because PTGui uses the Lanczos interpolator, which is said to give sharper results by itself?

aiwetir said: there used to be a product (maybe there still is) that would fit on your hot shoe and have a bendable wire with a clip on the end
Yes, it's called a flare buster (www.flarebuster.com). I recently bought one from the distributor in the Czech Republic (which was cheaper than buying it in France).
BTW I my infrared remote control will work from the back of my D70s when in a room with light walls and ceiling, but not when outside, so I am also using a 5 meters long wire remote control now.

I bought a levelling plate from Fanotec (the manufacturer of the NN3). That's much cheaper and just as easy to use.

Autopano Pro 1.4: accurate but unsharp?

I like PTGui but let’s face it: the program just doesn’t stitch nadirs properly. It takes me far too much time. And in 4 out of 5 cases, PTGui does not stitch the entire panorama properly if a hand held nadir shot is added to the source images.
Now I have installed a trial version of Autopano Pro 1.4 yesterday, processed 5 panoramas with it and I am impressed with the accuracy of the control point detection algorithm. Only a few minor corrections needed around the nadirs of 3 out of 5 panoramas. That saves a lot of time and irritation. Sharpness however, is dramatically less then when stitching with PTGui and this makes the result unusable.
I have read the thread on Panoguide about Autopano sharpness (www.panoguide.com/forums/qna/3493/), which seems to be out of date. I have selected the Bilinear sharper interpolator in stead of default Bilinear. It’s still not sharp (and fyi, yes, the source material is sharp).
The equipment I used is a Nikon D70s with 10,5mm fisheye on a Nodal Ninja 3. Images were shot in RAW format (and converted to TIFF before processing), ISO 200, f8 or f11, 1/200s or 1/250s.
So, is unsharpness a feature of Autopano Pro and do I have to export control points and stitch them in PTGui anyway?

There is no hood, since the FC-E8 has a FOV of 183 degrees.
With my Coolpix 5000, I prefer to use this lens in full frame mode (setting the camera to Fisheye 2) and take 8 photos (6 horizontal, 1 zenith, 1 nadir) which will improve the image quality significantly, since this uses the whole sensor. I only use the Fisheye 1 mode for bubble panorama's that can be displayed relatively small and even then, I take 6 picures horizontally.
