![]() ![]() If you want to calculate 360x180-degree spherical panoramas with this tool, you can only do that with rectilinear lenses, not fisheyes. 450mm in full frame equivalent, everything above this is too inaccurate due to the rounding to 2.5 degrees. The calculator is suitable up to a maximum focal length of the used lens of approx. The degrees are always rounded to 2.5 degrees, because I don't know any nodal point adapters that allow smaller degree settings. It is already included, because the single images will always overlap at least 25%, mostly over 30%. I would calculate a 20% safety margin.Īll other values are calculated exactly and do not need a safety margin. Due to slight physical inaccuracies during the shoot and depending on the software used for processing (Microsoft ICE, PTGui, etc.), the actually achieved megapixels will be lower. The megapixels of the panorama are the theoretically maximum achievable megapixels. With the electronic heads this is not possible, they take a picture after picture no matter what, and the panorama is useless. The advantage of the fully manual version including this calculator is that you always have full control over what is on the individual images and whether you wait until the cloud before the sun has disappeared again, or the tourists in front of the lens. You also don't need an expensive, electronic panorama head like a gigapan epic that costs 1000€, that takes over the calculations and creates the panorama at the push of a button. You only need a nodal point Adapter to get started. It cost me a significant amount of time to find the right formulas and program it within excel, so I do hope you can appreciate my effort. In short: Every information you need for producing the panorama successfully at the first try. The calculator then gives you the resulting megapixel and resolution of the panorama, the resulting viewing angle (horizontally/vertically), the necessary amount of pictures per row and the amount of rows and finally the necessary degree settings for your nodal point adapter in 2,5 degree steps. 3:1) and the desired, simulated focal length in full frame equivalent. It calculates the necessary dpi and the maximum print size in centimeters (sorry US).Ĭalculate Hi-Res panoramas and Gigapixel images: You have to specify the aspect ratio of the sensor(4:3 or 3:2), the megapixel of your camera, the crop factor, the true focal length of the used lens, the orientation of the camera (landscape/portrait), the desired aspect ratio of the panorama (i.e. I realized, that there is not one single tool, which can do the necessary calculations for you (note: the tool was written in german, I just changed the titles and descriptions to english, but not the pop up texts or the cells)Ĭalculate print sizes: You have to specify the effective megapixels of your image, the aspect ratio of the image and the minimum viewing distance. I want to present to you an excel calculator, that easily calculates panoramas, gigapixel images and print sizes in a simple to use interface.įor a contractor, I had to produce a Hi-Res image (approximately 380 Megapixel) for a big print (4,2m to 4,2m).
