Using multiple lens lengths in the same panorama

Hello Everyone,

I have been experimenting with combining shots taken using different lengths of lens. Is there some documentation? I had a look in the Wiki but couldn't see anything/didn't know what key to search on.

For those of you with time and inclination to read a long description of what I am doing and the problem I have ...

First I shoot a wide scene using a low number of shots using a 17mm lens. Then I re-shoot a portion of the scene using a 55mm lens and finally I re-shoot a portion of the 55mm portion with my 200mm lens. When I stitch the images I get what I expect i.e. a single panorama with links between the 17 and 55mm shots and more links between the 55 and 200mm shots, and the size of the image is calculated as if the whole image was made from 200mm shots.

In my mind the three types of shot make up three virtual layers with the 17mm images on the bottom, the 55mm images in the middle and the 200mm images on the top. So when I render the pano I expect to get a big low-resolution pano made from the 17mm images with a smaller region of higher-resolution 55mm images and an even smaller region of high-resolution 200mm shots. What I seem to get however is a pano made purely from the 17mm shots.

I know that I can make actual layers from the 17, 55 and 200mm images, render them separately and then paste the resulting panos on top of each other in the way that I want, but it seems to me that there may be a way of using AP to get what I want without having to do this.

Thoughts, anyone?

Re: Using multiple lens lengths in the same panorama

Hello,

In the advanced rendering options (or in the preview options in Autopano 3.0), you can simply give priority to 'long focal' pictures. Doing that, the pictures with the larger focals will be 'on the top' of the ones with lower focal lengths.

Does it solve your problem ?

Regards,
Thomas

Hi Aeris!

I wonder what might be a realistic advantage to go this way instead of using one and the same lens for the whole thing?

sky water, sees, white walls etc. can be taken from the shorter
the neigbors window can be taken the longer focal

Thanks Thomas. I wasn't aware of that option.
