PTGui - vertical FOV
Posted: 28 Jun 2007 at 6:11 GMT

I am trying to make a gigapixel arcitechual panorama of a cathedral. It consists of 280 images, which PTGui did an excellent job of autogenerating control points for!
I am setting the center point for the panorama at camera level, to get a projection where the walls do not "fall back" into the image.
My problem is that I then have to double the vertical FOV, as the centering moves most of my image "off-screen". I end up with an image double the vertical size (FOV), where the bottom half is empty. As this image already is huge, I get memory problems...
Is there any way to have an "asymmetrical" FOV, eg. more up than down...?

Hm, must remember to search before posting: the answer is in PTGuis FAQ 6.6 - not possible...

Hi, I use Hugin, but I think the workflow can be used for PTGui too: use Nona as stitcher engine, save as cropped tiffs, select output as multiple tiffs not multilayer tif, then use EnblendGUI or direct command line parametters to blend one row at the time then blend blended rows vertically.
info about enblend command line parameters can be found here
enblend.sourceforge.net/index.htm
that should help for memory problems.

DorinDXN is quite right, I did similar thing, I had 78 images from 350D (the green forest lookdigital.eu/hri.htm ), first of all PTGui could cope with it, then photoshop couldn't cope with so many layers (each layer around 20MB in tiff format); I finally generated 2 panos, each with half of the layers, then correcvted the errors and flattened them in photoshop, then I opened 2 flat panos in photoshop and manually stitched them in photoshop
