If you are wishing to shoot sphericals for display on the Web then choose a fisheye - you will need far fewer shots and the resolution of the stitched pano will be quite sufficient to produce a FlashVR of good quality capable of fullscreen display on the Web. The Tokina 10-17mm zoom FE is a popular...

AlexandreJ yes, as fma38 said, spinboxes, for example when I want to move an image using numbers for yaw/pitch/roll, I was always used to using a "." to write "0.5" (half). I don't see how APP treating both "." and "," as decimal separators would cause any confusion so I would like to see it do tha...

Fisheye and entrance pupil

Described near the end of this page: http://www.johnhpanos.com/epcalib.htm a fisheye lens varies the entrance pupil offset forward as the viewing angle increases. The suggestion is to adjust the head so the lens rotates around the entrance pupil as offset for the angle where shots will meet (and whe...

"I'd like to get any suggestions on what others might like to see it do." I'd like to see it work cross-browser. I'd also like the pan speed to not be constant, but to depend on how far the mouse is from the center, sort of like how Google Earth works. In this version I am only planning to do movem...

Phil, do you plan to show full spherical panos, or partial panos? It would be for a partial pano that could be painted on the inside of a cylinder. A hemisphere pano would be displayed as a circle if I understand it right. But if the rectangular image did go all the way to the top and bottom, I sup...

goals and requirements for pano display in web page

I'm back to working on a Javascript based panorama viewer. What I am trying to accomplish is the ability to view a panorama on a web page, where the panorama is wider than the browser window, and without having to use a horizontal scroll bar. I also want to animate it, such that the image is continu...

It seems if I make no effort to do cropping at all (e.g. do not click on the crop button), then it comes out apparently as desired.

I now have a much improved stitching from the church sanctuary panorama. The way I achieved this was based on comments about the excessive overlapping, too many links, and links deep into the images instead of the edges. I took all the original images and cropped them down to just the 50% part right...

I didn't save any. It was a while back on a previous computer system (so maybe 2 to 4 years).

I think if you gave up on trying to create a 360 and went for partail pano you'd get a reasonable result. Are those ranks of pews really that interesting? I have planned to do a 120, anyway. Presumably that should work since the front showed up fine in the 360. I showed people the other 360's I did...

Phil Shooting more images that necessary results in excessive overlaps which will cause even more problems when stitching - it will not ameliorate parallax problems, those can only be avoided by: 1. Having nothing much closer to the camera than about 100 metres. or: 2. Using a proper pano head with...

...Then I want to render that panorama at the exact pixel height desired (often a few different sizes), so I minimize scaling artifacts in the various sizes. I agree that the auto crop is often a bit too strong. To get the maximum area in the picture, I use the manual crop, zooming to 200%. The lin...

Hi Phil, I just looked inside your .pano file. I see that you shot 24 pics at 15° in landscape mode with focale 29.2mm equiv35 in a single row. You have about 76% overlapping which is really useless, it's even bad as you have 79 links in the pano when 24 would be enough. All these long links betwee...

Phil, I tried a stitch using every other image. I tried that, too. It still produced errors. The one on the right 6th pew was not as severe, but was present. There were a number of other errors, although quite small. With all 24 images, those others were gone or too small for me to even see. I did ...

You write about Autopano Pro, but it seems to me you are describing Autopano Giga. The former does what you want to do properly and automatically, the latter gives you a choice. "Edit > Settings > Panorama > Prefered extend" to make that choice. "Clamp to panorama content" is what you want. Note th...

stitching errors not seen in edit window

I am running into a stitching error similar to what sirwiz encountered. In my case I noticed that the stitching error is NOT visible in the edit window. But it shows up in the final result. Here is what the edit window shows (200672 bytes, 1159x928): http://phil.ipal.org/autopano/vance-pano/phil_van...

cropping, automatic or manual

Unless I am doing it wrong, it seems the automatic cropping (enabled in the detection settings) crops down to the point where no pixels will be lost. In other words, this is the smallest crop where all image pixels come through to the final panorama, even if some resultant panorama pixels have no in...

True, we don't know what is done inside. But we do have it narrowed down to contact closure allowing current to flow that prepares the shot and/or takes the shot. Obviously some voltage would have to be applied. I would also suspect that even when the switch is closed, that voltage is current limite...

I am pretty sure the 450D is the same as the 400D etc, so you can definitely use a 2.5mm plug and a Y connector. This page has the basic wiring schematics for a single camera. Worked on my 400D. They all use the Canon RS-60E3, so that seems to be the way it is wired. My next curiosity is if the con...

I don't know if this would be a solution, but it would be something I would try in a case like this. Do everything to merge the photo set up to the point of rendering ... if you were able to get that far before. Then use the crop tool to crop the big pano down to a smaller part, half, or third or qu...

Has anyone attempted to create 3D panoramic, or at least very very wide, photos? I can see many technical challenges in it (and that gets my interest). I would envision a double-mount pano head being rigged together to do it, using 2 cameras operated together under a common remote control. The image...
