Canon 5D MK II, Canon 70-200 f...
The National Park Desierto de los Leones was the fitst National Park decreed in Mexico (1917), but well before that was home of monks, who built the Monastery which garden is shown in this picture.
The panoramic is composed of 752 pictures taken by a Canon 50D and 70-200 mm zoom (at 200) on a Automate panoramic robot. It took me 2 hours to complet the shots, partly because of the Automate lost communication with the remote often, when I stopped the pano to repeat a skipped picture (because of unability to focus in the set time or because of a person crossing), causing a 5 or so minute delay every time I had to reset the PDA that acts as a remote control, and partly because I had to wait for people to move before continuing with the pictures, but despite that there are some incomplete persons and a "twin". The PSD file is 4.5 gigabites, but when converted to 72 dpi JPG became less than 1 GB.
A drawback of using a SLR is that the depth of field is much reduced as compared to the small sensor of a point and shoot. Because of that there are pictures of in focus objects in the foreground and a halo of blurr in the background, surrounded by sharp areas, which give the impression of badly pasted images. This problem is particularly bad in a picture like this one, where there are many objects at different distances, both close and far. Because of the long time it took to complete the pictures on a partly cloudy day there were many changes in lighting conditions, which is particularly noticeable in the trunk of the trees in the middle of the image.
The parameters I used were an overlap of 50% horizontally and 30% vertically. The time to half-press the shutter of 1 sec; time to hold the shutter open 1 sec; time to save image to card 1 sec; delay to move shutter after shutter press 0.5 sec; settleing time before firing shutter 1 sec. I need to check how long to extend the half-press time, in order to reduce the number of skipped pictures because of the camera failing to focus, which was the most recurrent problem during the pano.
