True enough, but *some* sources recommend an overlap between 30% and 50%. wasteful. What, exactly, is wasted? there is no need to have a 50% overlap for panos. it's a complete waste. If two photos in a pano series are overlapped by 50%, and are - by your definition - a complete waste, then neither is necessary to complete the pano? If only difference between what you mandate to be the necessary overlap and the 50% overlap is wasted, it would not be a complete waste? Now would it? nowhere did i mandate anything and it's clear you are just wanting to argue for the sake of arguing. You didn't answer the question. What is wasted? i did answer.

Explain it. there's no need, since it's clear as mud what is meant. If I take a photograph and crop that photograph to less than the full frame of what was taken, have I wasted something? yes. If we waste something, what we waste can be identified. We can waste time, money, effort, food, and even words. Attempting to get you to defend your more silly statements is a waste of words. as usual, more bashing. I have asked you to identify what is wasted with a 50% overlap when shooting a pano series. Surely, if you believe something has been wasted, you can explain what that something is. i did. The next question would be "What loss is incurred in the waste?". I won't ask that question because I know that you cannot, and will not, answer that question. i can, but will not because you aren't interested in an answer or a discussion. you just want to argue. |

Some may feel that a 20% overlap is not sufficient, but I doubt if anyone would suggest that the instructions say to pan the camera. 20% or so... That should work. I usually overlap to about 10% and haven't had any issues with CS5 stitching. I suppose detail in the image helps and if it is a less "noisy" scene, then more overlap would be better. It also depends if you are shooting in landscape or portrait orientation. Landscape gives you more leeway, portrait is far more critical. Then selection of an appropriate projection is critical. I'd assume the stitching program would have less issue in portrait as it would have a longer baseline per edge to line up with. That said all my panos are single strip in landscape - I've never done a 'tiled' pano (eg: 3 x 2 or some such) either. |

If I take a photograph and crop that photograph to less than the full frame of what was taken, have I wasted something? yes. Why is it wasted if it was always intended that it would not be used? -- Regards, Eric Stevens |

True enough, but *some* sources recommend an overlap between 30% and 50%. 50%? Hmm, consider frames A B C If A and C overlap B by 50% (each) then they'd almost or certainly meet in the middle of B. So pretty wasteful of memory (no biggie) and processing later on (perhaps a biggie). If the subject matter is sufficiently changing, an overlap of 10% is more than ample. If it's relatively "smooth" (to a limit) then more overlap is desirable. |

Another alarm bell rings about your claim to actually take photographs. more of your bashing. Actual photographers often frame wide as a safety measure to ensure the final composition is both balanced and inclusive of everything of interest. looks like the alarm bell you clam to be hearing is really about you. actual photographers compose their shots *before* taking the photo. they might crop it slightly later, but it's minor, if at all. otherwise, they'd just use a wide angle lens and point the camera in the general direction and crop later. The photographer doesn't know what part will discarded in the crop, but knows that something will be. The cropped-out part is not wasted. yes it is wasted, although it's usually minor. it's certainly not the 50% waste you were babbling about earlier. |
