Here's a few pano's taken on some recent trips. The Lighthouse is is Maine. The rest are in Canyonlands, and Arches in Southern Utah. Enjoy. . . .

Most of your panos can be softly commented…
But they are not titled. The whole series can be commented…
Then it becomes very difficult to make any observation !!!
Most of the time we would like to say something about one pano… not linked ones…
What a pity to not be able to just point to one or two images

BTW I'd like to make comments on

or this one
http://www.autopano.net/forum/postgalle … pano35.jpg
But no titles are helping me ![]()

I apologize for not giving more details on the pictures. Pano29 is nearby the entrance to the S. entrance of Canyonlands Nat'l Park in S. Utah down by Moab, Utah. This picture is of a place called 'Newspaper Rock' . It depicts ancient petroglyphs Anasazi and or Fremont Indians that lived in this area 800 years ago.
Pano35 is just some of the local terrain I snapped along the road as we headed out of the S. entrance of Canyonlands.
Pictures were all taken with a Sigma SD14 10-20mm zoom

Hi Richard,
Beautifully composed. I love the grand canyon shot, second from top, gorgeous!

Your set is globally beautiful, but some have very overexposed areas, did you work in raw or jpeg?
What is the average number of shots per pano?
Are you using photoshop?

My computer is a Linux machine so all of the photo's have been doctored with the 'Gimp'. I also used Picasa beta3 for the size compression and uploads. The pictures were all taken as jpegs. If I had the time I would have shot them all 'raw' and manipulate them in the 'raw' format mode with other software. The pictures that look 'overexposed' I assume you mean the areas where the picture is washed out is because some of them were
shot in shadows darker than the pictures reveal. It's tough to get an 'average' balance when you have very bright light areas and very dark shadow area's because of where the pictures were taken in relationship to the sun's position in the sky.

BTW I thank everyone for their remarks on my pictures. Most appreciated.

I am struggling with the same problem. Recently I attempted the following solution: I set my shutter speed to 1/25 of a second to capture the shadow detail, knowing that the sky would be overexposed. After capturing 120 images for my panorama, I reset the shutter speed to 1/100 of a second and re-shot the top row. I used AutoPano to process all the images, placing them in two layers based on shutter speed. I converted the two PSD files output by AutoPano to PNG format using psdparse, then combined the PNG files using enfuse.
The result was unsatisfactory because there was sky not only in the top row of the panorama, but also in the second row--I should have captured two rows at 1/100 second, not just one. I am continuing to experiment.

I don't know where is the shadow/highlight on the Gimp…
But maybe someone could help you…
Here is what its possible to get using that filter and the curves one.
Even with screenshots it's possible to get rid of some overexposed areas…
BTW, I love the first shot and this one http://www.autopano.net/forum/postgalle … pano35.jpg
The Petroglyphs one is very interesting because most the time people's shots must include the barrier, in being very close to the stone and making a pano, there are a lot of details shown ![]()

Something that I wish to attempt to experiment with is image stacking. With the camera on a stationary tripod and pano head . .. take a series of pictures adjusted to the same f/stop setting and use the shutter speed to take a series of underexposed shots, then repeat the process to overexpose the very same shots again by adjusting the shutter speed.Then use image stacking software (used primarily in astrophotography) to stack identical pictures (under and over) to give you a balance picture. Then run the final 'stacked' photo's through Autopanopro to stitch them into a panorama. It's been done by some people already i'm sure. . . .
Anyways thanks again for all the help, suggestions, and kind remarks.

Would you mind telling us what is your photographic equipment - camera and it's abilities, tripod, panohead etc… That will relative answers and avoid eventual criticism!
For your answer This is not really an image stacking, but an exposure blending.
The dynamic range can only be resolved by bracketing…
If your camera doesn't support it, a very simple technic can be used (with of course, no moving subjects like leaves or tree moving and of course ghost possible subjects like people or cars) but in your case, I find that including a subject as a woman gives a good scale to the whole scenery)
If bracketing possible, use it… + 2 EV, normal EV and – 2 EV…
Blending can be made whit enfuse 'free' app, and a GUI fitting to your plat-form.
If not, make two or three times the same pano, increasing for one or decreasing the speed for the second… We will try to help you into assembling all… I mean we will try ![]()
Make tests in your bakyard or in your local area… This is basic for tests
BTW… using manual exposure helps more in bracketing than with Aperture priority or speed priority That are almost like automatic exposure, we are looking for a real average exposure… To blend them…
