  • How to choose a detent interval (shooting interval) updated

    This is a FAQ.

    detent setting for a particular focal length

    you need overlap in the images in order to stitch. So you need to know the angle of view of your lens. For making spherical panos, you can use this online calculator
    www.frankvanderpol.nl/fov_pan_calc.htm
    Then, you need to take photos at a constant angular interval 20-40% smaller than the angle of view of your lens.

    I have made spreadsheets showing relationship between focal length, detent interval and % overlap.

    look for your focal length in the spreadsheet. read horizontally to find the right detent interval with desired overlap. If no suitable detent available, look for other focal length.
    Alternatively, find the detent of your choice, choose a range of % overlap, then get the range of suitable focal length.



    For the most popular lens, you just refer to vrwave database. Note that the focal length they use is shortest in the zoom range.

    As a beginner, you will find these info helpful.

    The calculator on this page seemed simpler...scroll down to mid-page. What do you think?

          If you are interested, I would like to submit my own calculator.
          I made it in order to know how many pictures I should shoot and where they should be placed.

            Here is the new version of the file I use to determine the number of pictures to be shot to achieve a panorama (including a video to explain how to use it) :

              This is very good information!

              I found out the hard way how many ? I needed for 300mm on a 1.6x crop factor canon, I found it, but with no click stops... anyways I now know that 195mm is the longest I can go with click stops! thanks nick fan!
