Very nice and crisp, Martin.
I have favorited it.
Is it your dog?
Did it appear on several shots by accident?

It's is not my dog. It was not an accident, I intended to make "dog twins". I usually take couple more photos of the interesting places after finishing the panorama. Nice example is here: http://photosynth.net/view.aspx?cid=7801bdf1-e657-4c3c-8edb-8da878f33620 Some of the boats and the diver were added later.

Can you tell me what tools and methods of stitching?I use PTGUI and PHOTOSYNTH software are not so good results.
LSOuWei Over 1 year ago
It works great, you use the equipment is what?
Martin_Kulhavy Over 1 year ago
I used Canon 5D Mark II with 70-200 f/2.8 IS II @ 200mm f/11; Manfrotto 303 SPH panoramic head. Total number of shots is 305. I stitched the photos in Ptgui, did some adjustment on the final photo in Photoshop (contrast, blending of the water) and then uploaded via the Photosynth Photoshop plug-in.

I don't create full panorama in Ptgui, I export several columns and then I merge them in Photoshop. This helps me to speed up the process, because creating of full panorama in Ptgui would require too much RAM. Photoshop is better in working with very large images. I have 12GB RAM and SSD hard drive. It is just enough to create this size panorama.

I just started to use PTGui photo, my camera and you, CANON 100-400 F / 4.5, when the camera what requirements?The following is my synthesis, the effect is not good, there are a lot of places to dislocation, can you tell me why?

Thank you very much!
LSOuWei Over 1 year ago
In addition, I also would like to ask, how to make no reference of "sky" synthesis in?
LSOuWei Over 1 year ago
Sir,please help me.

Martin,The photo above the pixel at 6.87Gigapixels, you use the PTGui synthesis this photo output has capacity? Use Uploaded to Photosynth from Photoshop plug-in will compress pictures capacity, thus affecting the picture clarity?
Martin_Kulhavy Over 1 year ago
I have checked your photo and I can see 2 problems:
1) There are some stitching errors. It looks like the photos were taken hand-held. If so, use tripod and a panoramic head with a correction for nodal point (there are many sites about nodal point - you can google it).
2) The horizon is not level. You can change the horizon in PtGui easily. http://www.ptgui.com/man/straighten.html

The panohead Manfrotto 303 SPH works in 5 degree steps, so for blue sky photos I can interpolate / extrapolate the yaw parameter in PtGui. I just manually enter the yaw values with 5 degree steps.

Thanks for the explanation about the dog, Martin.

I've also done some panos with the same people appearing several times - on purpose: see http://photosynth.net/view.aspx?cid=7efcce38-78db-4b21-9deb-85e2683d70b6 and http://photosynth.net/view.aspx?cid=0eddcd79-0ef4-44a9-a5f1-676217cd54f0

Hi,Martin,Have you tried the splicing different focus pictures, such as some of the photos was taken by 24mm, some photos are taken by 200mm, I want to split a very clear local effect.
Lieutenant Over 1 year ago
You stitching the photos are too beautiful.
Martin_Kulhavy Over 1 year ago
I have tried different focal lengths few times, but there were stitching errors so I didn't continue with this method. Currently I can get just enough of sky with the 200mm. I would like to move to higher focal lengths and resolutions, so maybe then I will need to develop something for different focal lengths (low detail for sky, high detail for the land).
Lieutenant Over 1 year ago
Hi,Martin,Thank you very much for your help, following this shot with a 300mm focal length to shoot over 200 splicing feel clarity is still not good enough, do not know why?There are photos of different focal lengths with stitching it?Your stitching a photo to be long, long late to be processed?You how to modify the splicing error?The the my stitching upload photos pixels is not how high ah, you can reach Gigapixels, I can only reach Megapixels.

Martin,when photographing a focus on how to choose?
Martin_Kulhavy Over 1 year ago
There is only a little you can do with clarity, the weather is the key. If the visibility is poor that I don't the panorama. Sometimes I wait for months, to get good conditions (England is not the best for this). There should be only small stitching error when using tripod and long focal length. It is useful to check the control points in Ptgui manually. I usually take couple hundreds of photos, with 20Mpix per photo the result is easily over 2 GPix. Do don't refocus. I focus at start on hyperfocal length, check the focus for infinity and then I switch to manual focus so the camera doesn't refocus.

Hi,Martin,I PSB save the use PTGUI, files modified PHOTOSHOP CS5 Save for PSB file, the file size small lot, a 22.6GB file, modify the dump only 7.69GB, do not know why,There is no way to fix it?
Now what stitching software is relatively easy to use, strong function?
MagiView Over 1 year ago
I use ICE for stitching: it's fast, easy to use, allows shooting with auto exposure and white balance - I find it just GREAT!
Lieutenant Over 1 year ago
Hi,Martin,I have a 30.2G PSB files, can not be used in photoshop cs5 plugin upload to Photosynth website, and you know why?
Martin_Kulhavy Over 1 year ago
Sorry, can help you here, I have never created that large PSB file. My biggest file is 12GB and there were no problems. I suppose that you have 64 bit Windows.
