Re: By Chick-on Request: Oh My Gosh Pan

From April 19th. The original image is 860 MB, not big by Giga-Pan standards, but big enough, 30 images at a focal length of only 35mm. The bridge is a 100% crop. This is a difficult location to shoot from. I used a specially modified bracket my friend made to mount on the railing so the camera could look down without seeing the railing. I still had to hang over the railing a bit to look through the camera.

Really nice shot. Well Done!

Love the full image. What camera? I am wondering why the crop of the bridge isn't really sharp?

17-85mm zoom lens. It's a compromise for hiking weight and expense. 35mm is marginal. 50 - 85mm is better but still not as good as a fixed focal length lens.

After posting the above I looked at other parts of the image and it looked sharper. Then I realized it might have to do with scaling the image during stitching. I looked at the original unaltered frame and sure enough, the image scale was much smaller. The stitched image was enlarged by 150%. I attached the same crop here from the original image and it looks much better.

This is the only pan I've ever tried that had to tilt up quite a bit and look almost straight down. The final row of images was just one field away from straight down. The stitching software really has to manhandle the images to get them to aligned.

I liked this pano a lot. Nice job.

But I'm wandering that if you had planned to shoot it at the 35mm focal length from the get go, then a fixed-focal-length 35mm wide-angle lens shouldn't have added that much weight, since they tend to be quite small and lightweight to start with. (Of course, one needs to own one or have access to one to make this advice practical.)

Still an excellent photo, especially capturing the lower portion of the falls by tilting your camera down over the rails.

I'm just not going to put a lot of money into a wide range of lenses. If I was to have a print made of that image at 150 dpi it would be 122" x 105". It would fill a wall and you'd still have view it from 6" to see all the detail. I'm not too concerned that the lens doesn't produce the highest resolution possible when viewing a tiny section at 100% on a computer display.

I had this image printed and it is mounted on my wall in five 28"x22" clip frames, 140" x 22".

It's a single row of about 20 images and printed at about 150 dpi. I have to get within 6"of it see the full resolution and it doesn't look soft. A big print is very impressive, almost like being there.

Thank you kind sir.

That was an excellent picture. Thanks for sharing it!

Very nice. That is from Columbia Rock correct? From the actual overlook or further up the trail?

Found it "After Columbia Point you have just a couple more sandy switchbacks and then the trail will flatten out for nearly a mile with a bit of up and down until you get into the valley cut by Yosemite Creek. Here you get your first views of Upper Yosemite Fall. At this point, pay attention and look for a spur that goes off to the right where the trail turns left. This is the so-called "Oh My Gosh Point", a lookout with the best views on the entire trail and a rail protecting the vertiginous view (but hold onto your children!). From Oh My Gosh Point you will look straight down on Lower Yosemite Fall and straight across at the Upper Fall and see almost all of the middle cascade. Once back on the trail, you'll soon pass the middle winter closure gate. At that point you are almost exactly half way to the top by time. You also have a nice flat section with views of Upper Yosemite Fall."

Is it from Columia Rock?

No.

Oh My Gosh Point is on a small spur trail further up the trail and around the bend from Columbia Rock.
