Latitude and Longitude of a Point. Strobox. Entrance Pupil Database. Wouldn't it be great if everyone entered their values for their NPP / Nodal Point / Entrance Pupil for lens and camera combinations. Some searching on the web will find a lot of people saying they want to start to create a database of some kind, but have not seen anything substantial so far (correct me if I am wrong).
Please enter your own values if they are not listed. Thanks, -- Richard Korff 11:12, 13 May 2005 (EDT) To cater for all the different camera bodies and lenses, the tables have been split into 3 parts: The first table shows the position of the tripod mount in relation to the lens axis. This is easy to measure and is dependent only on the camera body. Use as much as possible actual measurements rather than the reading on your panorama head , unless your are sure these are the same. To enter a line for your combination, edit the page by clicking edit at the top of the screen (you may need to create an account or sign-in first), and edit the table below. Tripod Mount Measurements. Lens Choices for Panorama. By Scott Highton for Virtual Reality Photography (www.vrphotography.com) March, 2008 In 1994, when Apple first released QuickTime VR, photographers had very little choice in what camera and lens types they could use for panoramic VR.
Shooting on 35mm film was the only real option, and Nikon’s manual focus 15mm f/3.5 ultra wide lens was the lens of choice, even though it cost close to $2,000. QTVR Authoring software required that source images for panoramic stitching be rectilinearly corrected (so straight lines in the scene appeared as straight lines on film), and the 15mm Nikkor was one of the widest lenses available of this type. The wider the lens, the more vertical coverage you could get in your panorama, since stitching was limited to a single row of images.
For many years, this remained the case, even as newer stitching applications came on to the market. As a result of their aggressive legal tactics, IPIX generated considerable ill will in the VR community. Lens Types. Online Depth of Field Calculator. Geotag Photos Online.
