    In answer to your first question - you don't. You tell the imager how big one photo is and how much of the scene you want to capture, and the gigapan automatically works out how many images you need to cover the scene (including overlaps). This happens like this: you first tell the unit how tall one picture is for the lens you are using - say 45degrees. You also tell it the width:height ratio of one picture say 4:3 so it can work out the width in degrees of one image - in this case 60degrees. Now you tell the imager where the top left and bottom right of the gigapan are to be (by moving the imager). Suppose it is a full spherical - then the width is 360 degrees i.e. 360/60 = 6 photos if they fit edge-to-edge and the height is 180deg i.e. 80/45 = 4 photos if they were to fit top edge to bottom edge. I.e. the whole gigapan would require an array of 6x4 images. But the images have to overlap so it turns out you needs something like 8x5 or 9x6. Try looking for "gigapan" on YouTube. There are instructional videos there. It's very simple when you have seen it demonstrated.E.g. I have taught the gigapan technique to 10 year old children. In answer to your second question - if it is not clear now - you can tell the imager to take, say, a 9x6 array of images but although the imager could work out what lens length you need for those 54 images to cover a 360x180 scene, there is no mechanism for the imager to make the camera use that length of lens. There is no reason why you couldn't have such a system (except not all cameras can be operated remotely) but the gigapan does not currently support this.

    Hi, how are you able to program in the exact number of rows and columns of shots to be taken? Their tech person seemed to be saying that for a 360 pan, you can only tell the unit where the top and bottom of the frame is, and then the unit calculates the number of shots by itself. Can you enter in the number of shots you want, manually?

    @Ronka - 4 is the number of snapshots i.e. the little pictures underneath the main image. Images like this are 9 x 6 i.e. 54 images with my 7D and an 18mm lens. The number of images required is not shown because I don't use the gigapan stitcher (which uploads this information by default)

    Hi, I'm looking into getting a Pro. How are you able to program it to only take 4 shots for these 360 pans?

    Yes, I rarely use anything else these days.
