I am planning on still using the 14-24mm but would like to use the 10.5mm for less important panos. Using natural night and interior lights, this takes about 5 hours which includes 1 hour setup, 4 hours of photography, and 0.5 hour of take down. I know the resolution of the 10.5mm will be less, but the 14-24mm takes me about 114 shots (3 rows, plus 4 apex, 4 nadir) which includes 3-exposure bracket at each position. I do mostly large buildings (e.g., churches). (4) Any comments on use of Nikon 14-24mm (at 14mm) f/2.8 versus Nikon 10.5mm f/2.8 DX for high quality panos and VR panos. I have not had trouble stitching in PTGui, but do you have any comments on the process? For a three row pano, I usually start with the downward angle first, then horizontal, then upward angle, then apex, and finally nadir. (3) I have read frequently that people start a multi-row pano with the horizontal row. Any thoughts on using the 10.5mm for two rows with a downward row and an upward row but no horizontal row? My reason for the two rows was possibly better overlap and easier stitching with the 10.5mm. #Ptgui stitch nadir trial#This did not stitch well, but I was not yet following the other suggestions you had made on the newer pano trial which was single row, apex, and nadir. #Ptgui stitch nadir full#There was plenty of overlap between rows and I had a full 360x180 coverage. (2) My first trial attempt with the 10.5mm was a two row (first downward angle, next upward, apex, and nadir). Any thought as to why this same process did not work for this pano using the Nikon 10.5mm f/2.8 DX on same Nikon D7000? Those panos were all taken with Nikon 14-24mm f/2.8 on a Nikon D7000 (DX). (1) In the past, I have successfully used PTGui to stitch apex shots with a different orientation (landscape versus portrait) than the images in the pano rows which were taken as portrait. Please take a look at these if you can and let me know is there are any other suggestions that you may have.Ī couple of other questions for my better understanding: I have posted the updated images and project file again at: I can declare the 10.5mm DX lens test a success and proceed now to a real panorama. #Ptgui stitch nadir movie#The resulting flat panorama and VR movie showed no noticeable misalignments or out of place artifacts. With these changes PTGui reported "very good" on the alignment with max distance of about 16. Thank you for being so helpful and especially for providing your PTGui project file which was most useful.įor the nadir shot, I created all control points on the flat surface of the floor, masked the tripod as you did, and set the viewpoint correction for that image.įor the apex shot, I rotated the image clockwise to "portrait" and created all control points on the flat surface of the ceiling. However, in the past, all I ever needed was usually just one Apex and one Nadir shot. I have additional Apex and Nadir shots that I did not upload if they are needed. I also uploaded one image for the flat pano output for the single horizontal row and also one image for the complete horizontal plus apex and nadir. I have uploaded the 6 horizontal images, 1 apex image (taken at same position as first shot of horizontal row), and 1 nadir image as well as the PTGui project file at: I am thinking that the problem has to do with characteristics of new lens. Have followed similar procedure with my Nikon 14-24mm f/2.8 on Nikon D7000 with no problems. Viewpoint correction on Nadir shot does not seem to help. Process followed is 6 portrait images taken 60 degree apart for horizontal row, followed by Apex shot straight up and Nadir shot taken at an angle. The distance on the Apex/Nadir control points is very large. Can not stitch the Nadir and Apex images in with the horizontal row even though created what looks like good set of control points. Can stitch the single horizontal row without problems. #Ptgui stitch nadir how to#Did test photos to learn how to use and stitch images for this new lens with PTGui version 9.1.9. Recently acquired Nikon 10.5mm f/2.8 DX full-frame fisheye on Nikon D7000 for creating VR panoramas.
