Tutorial first step

Regarding my posting on the hugin-ptx (hugin and other free panoramic software) list, for the moment I have decided to make a start on this panotools wiki. I expect to find out how serious the recommendation of 150kB max upload size is. In principle I would prefer not to scale down the images I wish to use for illustration.

With the nice new feature of exposure correction in hugin0.7beta one should start soon to write new advice on how to set the camera when photographing a panorama scene. Maybe fixed aperture?

Instead I made a start with Dust Removal with Flatfield recycling text and images of mine, consider it a test of the features here in the panotools wiki but being more useful than just a sandbox exercise. -- Klaus 20:24, 2 December 2007 (CET)

Photos for panoramic images using new hugin version

The usual recommendations hold like

  1. rotate camera around non-parallax point
  2. rest your camera or use a tripod, possibly with panorama head

Newer recommendations would be

  1. better do photos with slightly more than 50% overlap
    1. helps the exposure and vignetting correction
    2. no gap if one photo is spoiled
  2. do NOT use the camera panoramic mode
    1. you risk to have several photos with blown highlights
    2. little control over a number of features
    3. you possibly want to set the distance manually
  3. use fixed aperture (question)??
    1. one vignetting correction can be used
    2. one flatfield for dust removal


from own experience

  1. set the focus to manual
    1. know of several cases where the odd photo of a series would not focus, spoiling all, high risk with featureless panorama parts or non-representative distance in mid photo
  2. if your camera is dust-prone, take a photo of clear sky (could be processed into a flatfield)
