Topic: Stitch / Stitcher upload weirdness

Mosley – I’ve seen a few of these since Stitch went to 2.0 and I have an image set that will produce it, if Paul Heckbert needs it for testing. It seems more common with 360 degree panoramas, but it isn’t limited to them. It’s definitely a stitching bug, not an uploading bug – one of the very few unsquashed by Stitch 2.0 (in fact introduced in 2.0).

Topic: Photo Editors / Photoshop file size limitation

I would probably:

-Sample some of the darkest and lightest images in a RAW editor, find a happy medium of adjustment that applies to all.
-Batch process adjustments and slight resize (like David said) to get under the pixel limit.
-Stitch

If you do your editing in RAW before converting, I don’t see any reason to stick with TIF format. JPG would be 1/7 the size and save you some Methuselah-length load times.

Hope you get it figured out! Post a link when it’s up.

Topic: Stitch / Stitcher upload weirdness

I stitched and uploaded this pano last night. When viewed on the Gigapan site, it seems to have a detached strip of image above it that pushes the image downward in the viewer. This is a new phenomenon to me – no clue what’s causing it.

Topic: Photo Editors / Photoshop file size limitation

Photoshop will not open a file with greater than 300,000 width or height. There is no Photoshop flow around that limit. Best thing is to re-stitch the file in parts that stay under the limit and then open the exported TIFF files and re-scale just enough to be able to paste the pieces into a single file under the 300,000 limit. Photoshop can merge the files and blend so that the seam should be invisible. In your case, you will need about .78x reduction of the Photoshop image and you will be under the 300,000 limit for a re-combined file of two partial stitches. Needless to say you will have a lot of wait time during the process.

Another thing to consider is you could select a lower resolution setting on the camera that will give a smaller total pixel width. Also you could batch process reduce the originals you have already taken before you stitch.

You will need a lot of patience as it takes a long time to find out that something didn’t work.

Topic: Photo Editors / Photoshop file size limitation

I have only one GigaPan that rivals this in size and I didn’t even attempt to open it in Photoshop, as I recall.

Please consider uploading an unPhotoshopped version, even if just temporarily until you figure out how to clean it up to your liking. I, for one, would love to see how a GigaPan produced with this hardware looks before being touched up. What lens were you using? I’d love to see all of that metadata that GigaPan Stitch outputs (and that you lose after editing in Photoshop).

[Update: I see it’s already up on the site. Beginning to explore it now…]

Good Luck!

Topic: General Gigapanning / Inconsistent light in stitch

^^ For Canon users with a similar problem, David was referring to the “Auto Lighting Optimizer,” which can still function in manual modes. You can turn off the effect in the RAW software if you forgot it on the camera.

Also, some buildings turn their pretty exterior lights off completely at 12:00am to save power. I’ve had this happen a few times mid-shoot so you might want to check before/after.

The explore score may degrade over time if the gigapan at question is getting less traffic.

Topic: Photo Editors / Photoshop file size limitation

OK, I have finally done it! I made a GigaPan on Saturday with 1515 source images in it. I am using the Canon 1ds Mark II camera, so each image is 60.2 MB. These combine to make an image that is:

384,728 × 40,736 pixels

When I attempt to open it in Photoshop, the program tells me it cannot open an image greater than 300,000 pixels in either dimension. I am running Photoshop CS5.5 on a big Mac Pro tower with 8 processors and lots of RAM; I don’t think I have other limitations.

This is the largest photo I have ever made, and I would like to continue to work at this resolution. Any suggestions on how to work with files this large in Adobe Photoshop?

Thank you,
Brian Lawler

Topic: General Gigapanning / Finding Nodal Point in Canon 100-400mm

I have your points for the Canon EF 100-400mm f4.5-5.6L IS USM lens.

I used a T2i body, but since the flange to sensor distance is 44mm for all Canon EF mounts this should apply to any Canon DSLR.

Charles, I tried the paper method. The minimum focal distance on a 100-400 is 1.8m, so I couldn’t even see the paper before it was several feet away, and if you’ve ever tried looking down a 400mm lens to guess at the entrance pupil, it’s like looking down a well.

Assuming you use the mount ring that comes with the 100-400:

400mm:
Bad news, visible parallax but the camera needed to move forward beyond what the gigapan platform would allow. Slide the mounting platform as far forward as it will go and pray to the stitching gods.

200/300mm:
Between 200-300mm there was no obvious parallax with the platform all the way forward at “0”.

100mm:
Moving the mounting platform back to “60” appeared to give good results examined at 10x zoom on Live View.

Vertical Height:
Adjust the vertical tabs so the arrows are halfway between the upper and lower curvers of the lens barrel, I eye-balled this at about “65” on the Epic Pro scale.

Conclusion:
Unless you are shooting shorter than 200mm, you can leave the mounting plate all the way forward at “0”. If you need to shoot with foreground objects, stick to 300 or less.

These are my own observations, and I’m happy to share my testing method if anyone wants to check my numbers.

Fred,

I have some values for you, and there was an identical question in the general gigapanning section so I’ll post them there, just look for “100-400” in the title of the post.

Topic: General Gigapanning / Share your mistakes!

Oh man, Tim you really figured it out the hard way but your mention of blocking the viewfinder is a great tip.

Older Canon lenses with Image Stabilization don’t know what to do when sitting extremely still, such as being mounted on a tripod. The IS tries to correct shake that isn’t there, and actually ends up creating vibration by itself.

Thank you very much, Kevin.
Any plans for allowing 360° panos to rotate indefinitely – like on photosynth.net (for instance http://photosynth.net/view.aspx?cid=7efcce38-78…)?

Topic: Digital Cameras on Gigapan / Gigapan Pro with D800 : what lens?

Yes and no.
Yes, the 300 f/4 is OK for the EPIC Pro.
But with such a long lens, you wont be able to capture the azimuth with the EPIC Pro.
Also, a 360° spherical pano with a D800 and 300 f/4 requires several thousand photos. The pano will be a few tens of gigapixels, which cannot be handled by all softwares. Processing will take hours, if not days, with an ultrafast computer. Succeeding such a pano is a real challenge! So think twice if you are not a true pano expert!

These look great Terry! I don’t return to the site until October, but if I’m successful this will make for an amazing panorama, both for Gigapan enthusiasts and definitely for archaeologists. Thanks, I’ll post a link to the pic when I’m done.

Topic: Stitch / Sticher 2.0 and EFX

I purchased an Epic Pro directly from gigapan.org, but I didn’t get an e-mail (and I searched for it). After investing so much in the equipment, I think it would be reasonable for current users to be offered an upgrade path.

Topic: General Gigapanning / Impossible Panorama Shoot?

Dear Gigapan Users:

I am stumped and looking for ideas. There is a ceremonial structure that I would like to shoot in Peru. The building is 30m per side (here is a picture of half the length of the front that I’ve taken already <http://gigapan.com/gigapans/108285>). In the front I have about 50m of space to step back. However, there are carvings around 3 sides of the building (the back is still covered and thus inaccessible). On the sides I can only stand back about 5m or less resulting in presumably a distorted and huge panorama. Is there a way to shoot all 3 sides and stitch them together in a uniform way to capture a single shot of all the iconography? Any ideas greatly appreciated.

Best,
Matt

Yes, explore score is affected most definitely by traffic, as well as time.

Angelko: What’s funny is that about two days ago, the rest of my pictures were evaluated. Furthermore, my latest was scored a 138 almost immediately…so thanks. However, my first two photos had explore scores above 100 and now they’re closer to 50…why the change? I guess I don’t entirely understand how the explore score is evaluated (e.g. a algorithm? based on viewing traffic?).

The Savings Bundle for Stitch EFX is offered to those who purchase an Epic Series Imager directly from gigapan.com. The email Angelko referred to in early March 2012 was the Stitch EFX release announcement. Sorry, any discounts offered at that time are now expired.

Topic: Gigapan Mechanism / Shooting order

Matthew, thanks for the reminder. Yes, the Epic Pro can shoot columns-right, columns-left, rows-down, rows-up. The Epic and Epic 100 can shoot columns right, rows-down, rows-up.
