I am trying to take a panoramic image from my parents' balcony and then create a print. The horizon covers areas of Baltimore City within 5 miles to the Chesapeake Bay Bridge which is 35 miles as the crow flies.
I went all out with my lenses, and I set up my FD 600 f4.5 with the FD-EOS converter, which results in a 756mm lens. Including the crop factor it factors out to the AOV of a 1210mm lens. I set it up on my tripod and tried to get decent points of overlap. I used portrait orientation to get more height and accommodate the varying landscape. The view is certainly less than 90 degrees, probably more like 60 or less. I took 56 images to get the entire field of view.
I stuffed this all into Photostitch, and the first issue is to set the focal length of the lens (in 35mm equivalent). I first plugged in 1210mm, but it didn't seem to like that much at all, so I tried 756mm.
Photostitch chews on it for a while and comes back with a message about not enough virtual memory (I don't have the exact message as I type this). I have tried rebooting in case the culprit is a memory leak, trimming back the size of the image, and every other option I can think of to try and get the pano image. It produces an image file the correct width (number of pixels), but the right half of it is black. The left half looks normal at the top, but has a vertical streak effect below the normal area of the image.
Before I go back and try again with a shorter lens I would like to know what is happening here. Is it too much lens (756mm)? Or is it too many pixels (portrait orientaion, 6 MP, 56 images)?
I did the search here about using PS versus Photostitch, so maybe I'll try that, but it seems like Photostitch has some advantages over PS/CS.
Any help would be greatly appreciated.
Have Fun,
