Topic: Web Site and Forum / Explore Score No More?

I don’t know the algorithm for calculating the Explore Score, but it seems it may have been tweaked (recently?) to increase the decay rate for GigaPans that aren’t seeing a lot of activity. Combined with the decreased traffic on the site overall and inconsistent/slow updating, this has led to a metric that is not particularly meaningful at best, and punitive and discouraging at worst.

I’ve basically ignored the Explore Score metric as being unreliable/unhelpful (and mildly game-able) for quite a while now, but it’s getting to a point where too many other things (Gallery ordering, for example) use it as a proxy for importance/significance, when it is poorly adapted to that purpose.

The proliferation of Explore Score 0 is getting to be a real problem for a site that uses this number as its primary ranking system (total views being generally the secondary ranking criterion). I’d really like to see an open discussion of how this value is calculated and/or private discussions that include the input of regular users/power users.

Topic: Gigapan Mechanism / Free movement when switched off?

Have you tried using “Last Panorama”? It’s basically made for this precise situation – even keeps you aligned with the grid of the original panorama. I usually just move around with the arrows while it’s asking for the starting position and then release the shutter manually. Repeat as necessary. You can’t get the extra columns and rows that Tim requests (I agree this would be a useful feature for future versions of the firmware), but you can reshoot anything within the original grid.

Topic: Web Site and Forum / Snapshots not working consistently

Hi
Just one more thing that might be relevant. If you are not logged in and you do a search via view —> Snapshots, the snapshots appear. Clicking on a snapshot then takes you to the gigapan and all the snapshots for that gigapan appear as you would expect.

Topic: Web Site and Forum / Snapshots not working consistently

Hi Angelko,

I can’t see an existing topic for this item, so it may me just me having the problem.
All my older gigapans (Pre site upgrade) still show snapshots in the usual way. These appear to all viewers regardless of the viewer being logged in or not (i.e. non-member viewers)
However the newer gigapans don’t present snapshots to casual viewers. I can see them when I’m logged in, but not when I’m logged out. Specifically gigapans 102528 and 110055 are examples of post upgrade gigapans that don’t show snapshots to non-member viewers.
Is this the new normal behaviours or a bug?

Topic: Web Site and Forum / Explore Score No More?

Hi Angelko,

I’m afraid I’m having similar problems with the explore score. It seems to me that since the site was upgraded I have lost explore scores on all my gigapans. Also the new ones that I have uploaded since the site upgrade are still at zero. Another interesting observation was that Gigapan 102528 got a huge score initially but now it’s back to zero.

Topic: Gigapan Mechanism / Free movement when switched off?

Not totally sure what you are trying to do, but the epic 100 moves left/right on its base pretty easily when it is off, the epic pro does as well. Moving it on the vertical axis (up/down) is hard, you can sort of do it smoothly on the epic 100, definitely not on the Epic Pro. I’m not sure if it hurts the servos to force them around a lot when the epic is off but you definitely are pushing against the servo when you move the camera in the vertical axis even when it is off.
It would be nice if the epic pro had some feature where it was tracking the field of view of your whole panorama and gave you additional options for repeating parts of the image or adding rows or columns if you decided you wanted to shoot a bigger image after you finished the pano, etc, but there’s nothing like that yet. On both Epic and Epic Pro can repeat the last pano and (tediously) move the camera to any position in it if you want to repeat a single image but it’s not that easy to do except for repeating images you just missed, etc.

Topic: Gigapan Mechanism / Manual or Autofocus in crowds?

I’d agree that manual focus might be best (unless the stadium is strangely shaped so the distance to your subject is inconsistent), but if you do go with auto, sometimes in challenging environments it helps to set the the auto-focus point on the camera to just the center square (you know on the DSLR, all those boxes on the screen, choose just set the auto focus to use the center one). This lets the camera just focus on whatever is in the center and not get messed up if there are other things at varying depths. Fails completely some times but in some situations it save the photo.

You also might consider which order of rows and columns you go with for the shot. Like it might work to do “Rows Down” so you can do the sky on manual focus (or auto with the full image for the focal points) and then when you get to the people shift the focal point setting to “center only” as described above and do the people, then maybe switch focal point back to the whole image for the rest of shot. Something like that.

Topic: Gigapan Mechanism / Free movement when switched off?

After shooting the panorama I’d like to shoot some extra images from the same position. So I would leave the camera on the epic and move them by hand. Is that possible or does the motor block movement when epic is switched off?

Topic: Special-effects Gigapans / HDR Workflow

I agree with Tom on the workflow. It looks like you may have some lens vignette going on. Try batch processing the source images in Photoshop’s Lens Correction module to remove lens vignette before batch merging them in Photomatix. Photoshop needs the EXIF data to choose the correct lens profile for vignette removal, so I doubt it would work post-photomatix.

Hi, Mosley!
Thanks for your reply and link. My technical knowledge and understanding is not at the level of some of the information published in the link, therefore I hope you will have the chance to post the list and the corresponding notes.
Thanks again,

Topic: Digital Cameras on Gigapan / Panasonic LUMIX FZ-150 on EPIC 100

You have to make an entirely new cable. Here’s a link to a forum with the schematic.

http://forum.getdpi.com/forum/showthread.php?t=…

I had to do some additional research to figure out the US eqivalent parts. I sourced them all at Mouser.com, except for the plug into the imager, which can be found at any hobby store that sells R/C planes, boats etc. That sounds odd until you consider that the button pusher uses a standard servo that’s also used in R/C planes.

I’ll post a shopping list and some notes this weekend when I have a few minutes.

Are you bummed that they just announced the FZ200?

Topic: Gigapan Mechanism / Nikon D90 with 200mm lens – accept parallax?

Depends on the scene.

If you are in a situation where everything is far away (top of a hill for instance)then you should have no problems.

Ditto if everything is the same distance away, but not too close (side of a building).

If you have a fence, bushes or similar in the foreground then you are likely to find two versions of them appearing.

With shots like these, it really comes down to how well your stitching software handles ‘ghosts’.

In extreme cases, it might be necessary to modify individual shots to remove the offending portions, but this can be tricky if they occupy more than one row.

Topic: Digital Cameras on Gigapan / Panasonic LUMIX FZ-150 on EPIC 100

Hi, Mosley!
I´ve also bought a FZ-150 recently mainly because of its huge optical zoom and the capability of taking raw images as well as the remote control. Regarding this one do you have some specific procedures to share about the conversion of the shutter cable you have refered to? I have no solding capabilities, but will or could find one who has. I actually have the cable gigapan sells, but tried it and it does not work on this camera. What are the modifications that should be performed to make it work?.
Thanks for any hint.
Regards, Martin

Topic: Gigapan Mechanism / Nikon D90 with 200mm lens – accept parallax?

Hi. I’ve just bought a GigaPan Epic Pro and have tried it out with a Nikon D90 with a Sigma DC 18–200 mm lens. Calibrating the device with a low focal length gives me no problem in regards to finding the entrance pupil thus getting no parallax. My problem is that I can’t seem to adjust the rail far enough to shooting with a higher focal length than about 80 mm. So my question is: is it normal to accept some parallax on telelenses such as mine?

Thanks.

Topic: Special-effects Gigapans / HDR Workflow

Hi Tom

THanks for the input i tried what you sugested and this is what came out of it http://www.gigapan.com/gigapans/109900

Any thoughts on how to get a smooth image? I think maybe i should use 75% over lap and a then take a general test HDR shot for me to get my numbers right, there is no way to preview when you batch is there?

I doubt image size is the problem, Jesse. Try batch merging them to HDR and outputting as a JPEG or TIFF in Photomatix, then cropping them.

Topic: General Gigapanning / Measuring Tools/Software

Are there any tools or software available to get length measurements in spherical panoramas? I know there is GigaMacro but that seems to only be good for photos of really small objects. I am working on a research project that involves photos of human sized objects and even buildings. If there is not software available, does anyone have an algorithm or know the math to do this?

I have the same question. Are there any programs or tools available to do measurements on gigapixel photos that are human scale? And what is the GigaPan ID?

Topic: General Gigapanning / Image size when shooting

If you don’t shoot in RAW you may get stuck with a bad white balance that could have been easily corrected.

Hey Shawn:
A D800 owner walks into a bar and sits next to a gigapanner. The gigapanner looks bummed out, so the D800 owner says, “Hey, why the long face?” The gigapanner looks up and says, “I just shot this huge panorama, it’s almost 100 megapixels! But the stitcher isn’t working, I think one of my images is missing.” The D800 owner thought about this a moment and then asked, “Is it the left one or the right one?”

Topic: Digital Cameras on Gigapan / Panasonic LUMIX FZ-150 on EPIC 100

I’ve just picked up a Panasonic LUMIX FZ-150 to use with my EPIC 100, and am so far very pleased. It looks like it will be an excellent Gigapanning camera. Here are the reasons I bought it, in no particular order:

600mm optical zoom
Leica glass
standard 52mm filter thread (take that, Canon!)
additional zoom controls on the side of the lens (not just around the shutter button)
Focus button on the side of the lens (Set the camera to manual focus then press this to use AF once)
Zoom setting memory and manual focus memory (after you turn the camera off for a battery or memory card change)
configurable 3-shot bracketing
Uses SDXC cards
RAW
Ability to use a shutter cable (which is easily made if you can solder) rather than the button pusher

The amazing amount of resolution offered by the D800 has a significant downside.
