Description

This is my first Gigapan that I have attempted. It was taken from the peak of Squaw Mountain. Before leaving I had no idea how hard it would be to make the hike with my Manfroto tripod, 7D, 70-200 lens and the Gigapan Epic Pro. I was freeeezing during the setup and 37 minutes of picture taking. Something I suspected was that there would be a variation in ambient light as the sun was setting. Because it was so cold and I was alone on top of a mountain I thought it not prudent to wait much longer for more consistent lighting. Longer exposure would also have helped to get more detail but once again because I was anxious to leave I set my ISO to 4000 and dropped my aperture as much as I could to save time but still have a deep enough DOF. The IQ of the image is a little low because of the high ISO used. I've decided to redo the shot after having made better preparations. The plan is to use a 400mm lens with a 2X extender to give me 1280 mm of reach on my 7D. If my calculations are accurate this should give me 8x the resolution. I'd like to get more detail in the underexposed areas and avoid having the hot spots being lost (lit signs etc.) so I may also bracket for HDR. My only concern is that it may take 3-4 hours to do all this and I don't feel like chillin in the snow on top of a mountain at night waiting. It just may be worth it though. In any case though, this is just my first gigapan. I’m sure the ones to follow will be much improved.

Any insightful feedback would be much appreciated :)

    It turned out a lot clearer than many of the other nighttime panorama's I've seen on here. The view is incredible up there as you can see the copper mine all the way down to Springville. What would really be spectacular is if you had a daytime version and a nighttime one from the same spot. It would take hours, but it would be amazing. One thing I notice is that you used automatic white balance. I guess that doesn't matter much on a night panorama, but I've found that causes me problems when I shoot them during the day. I now fix the white balance on daylight or cloudy (or whatever), so none of the frames have a different color temperature that messes up the panorama. I also set the picture style to "neutral" or "faithful" so the colors don't shift between frame shots. The other modes seem to enhance colors differently per shot and cause color issues when stitching. Anyway, very well done and I'm impressed with both your dedication to getting the shot as I am the outstanding results for a first go. You picked a great site to shoot as well. I look forward to seeing more of your panoramas on gigapan!

    @ TheShot Thanks! I took the shots at f9. All the data is in the Stitcher Notes. Ideally I would have taken the shots at ISO 400 or less but because of the cold I had to get them all as quick as possible. There was some wind and my tripod wasn't super stable but the new IS system of the lens really helped keep the shots sharp.

    Awesome Loren, this is really cool shoot! Wow, that's some serious dedication to climb that mountain to take this shot. It turned out really good and I appreciate you explaining how you took it. I've tried taking shots of the Salt Lake Valley at night and they have turned out bad because of wind or poor camera settings. I'm still learning a lot too. What f-Stop setting did you use?
