Description

This is a test of a technique to capture action in low light. I used the Canon G10 to capture the scene at .25-.60 second, ISO 80, accepting the fact that I could not capture peak action. I then shot action with the Nikon D3 at ISO 1000 and patched those parts into the scene in Photoshop. The Canon fits the GigaPan but has poor high-ISO performance; the Nikon works superbly at high ISOs but won't fit even the Epic 100. Let me know if you think the result is realistic. This GigaPan has been sized down to fit the 3K-per-side limit for JPG files-- the larger TIFF and RAW files would not upload.

Gibbons are apes, not monkeys. These gibbons come from Southeast Asia. There are seven gibbons, eleven ducks and an English sparrow in this image -- can you find them all?

    Hi Federico, As so often happens, the GigaPan missed photographing the gibbons (except once). So I didn't have to retouch out blurred apes. I left the one blurred image in so I could show the difference between the slow G10 photos and the fast D3 photos. best regards, Tom

    Congrats, Tom, very good job indeed, though sounds like a hard work to do, besides taking picture with Nikon each one of animals in fixed poses I supposed you had to cover up the "phantom" animals taken in the first place,right? how did you accomplish that?

    Hi Keith, I stitched the entire panorama taken with the G10, then in Photoshop I dragged in the action photos and positioned them. GigaPan Stitcher distorts the source photos in the stitching process, so I had to distort the action photos to match. Then I flattened the panorama to save file size. Two techniques to aid in positioning (both in Photoshop) are to reduce the opacity of the upper layer so you can see the background through it, and to change the blend mode to Exclusion. In Exclusion mode, the image turns black where the pixels are identical in the upper and lower layers. Once I had the new layer positioned, I changed the opacity or blend mode back before flattening. The Nikon D3 has much less depth of field at a given focal length so I had to finesse the edges of the added elements. Tom

    Hi Tom I really like what you have achieved here. Did you just replac one segment for stiching or did you cut out the animal as a layer? Krbristol

    Thanks for the suggestion, hophi, but the 2GB TIFF is flattened and has no alpha channels, paths or saved selections.

    Tom, did you check if you still have a second layer or a mask or a path saved with your raw ps file...? this usually prevents the gp from uploading... great pano.;-))

    I really like this panorama. Great job. The white cheeked gibbons are darling and the overall quality of the gigapan is excellent. Sincere posting of related links is encouraged as this is the way that I stumble upon things that are really great.

    Regarding large files, the uploader normally copes with .raw files provided they are saved with three interleaved channels, no header and a name like mypic_WWWxHHH.raw where WWW is the width, HHH is the height and mypic has no numbers or underscores. You are right about TIFs in the sense that originally they were supposed to cope with files up to 4GB, but some morons mucked up the implementation and used signed arithmetic so now, for consistency, the limit is 2GB for everyone. There are now very few programs that will cope with a TIF that is over 2GB, and the uploader is one of them. I assume you wrote you file as a compressed TIF? If the file is over 2GB using LZW compression then it is sometimes worth trying ZIP compression. It's very slow to compress with ZIP, but if the file is 2.something GB, ZIP sometimes takes it to under 2. (However, it doesn't matter what size the file is on your disk, the uploader always uploads the same amount because it uncompresses the file, turns it into hundreds of little compressed JPEGs and uploads those.) With regard to adding links, yes, it is true I am a shameless self-publicist and have some of the highest explore scores as a result. On this occasion however you'll find that if you follow the links, Texas_Photo and I are engaged in the much more ethical enterprise of identifying pretty girls :-) That said, my encouragement for people to include cross-referencing links is motivated by a genuine desire to see more connection between contributors to gigapan.org. I also think it would be fun to see chains of links that take one from say Berlin to New York via Milan and the interior of an interesting piece of granite.

Sometimes the references are pretty obviously plugs for your own work, like your and TexasPhoto's conversation at www.gigapan.org/viewGigapan.php?id= 27287;-)

    Hi Kilgore, Since I had to work on the image in Photoshop, I saved it from Stitcher as a RAW file and opened it in Photoshop, then saved it as a .PSB large document format file. This allowed me to do regular manipulation. The finished .PSB file was a bit under 4GB and there was no other format to save it to. TIFF can supposedly save up to 4GB but I got an error. I sized it down to 2GB and could save it as a TIFF but the uploader wouldn't take it. I sized it down again as a JPG and could finally upload that. I could have saved the aggravation by doing my manipulation on the source files before stitching, but I didn't think of that and didn't want to redo all that work. Let it be a lesson to me! Tom

    Great gigapan Tom. Big enough and loads of details. It's good to see other people experimenting with different cameras and techniques. (I have been playing around with tone-mapped gigapans. tinyurl.com/lmhmpj Will open in
a new tab or window is probably my best so far.) I'd say your efforts have paid off - the gigapan looks great on my system. As someone who generates, edits and uploads big image files, I wonder what your problem was with TIFF and RAW formats? I sometimes have trouble, but I usually get there in the end. Are you using the latest uploader for your computer? I have just used version 0.4.4154 for Windows to upload two gigapans that were 10Gpix/30GB RAW files. By the way, I thoroughly endorse Texas_Photo's comments re geocoding. Imho a gigapan is incomplete without it because gigapans look so much more spectacular in GE. It is a pity that it is so fiddly to get everything lined up properly using the current system. (Having said that I can't think of a better way of doing it until the imager contains a GPS and can download this info.) I'd also recommend that people include cross-references from their work to any other gigapans that are related in some way. Imo this generates more interest and, for those of us who like to see explore scores, more hits. Actually it works better if you put a link to your work to theirs because then they see your link and might want to reciprocate. One day perhaps the gigapan system may include automatic notification that someone has linked to your gigapan.

    Now you can do this for all of your GigaPans and when you go to gigapan.org, bottom right corner, click on Browse in Google Earth and it will D/L a folder with two icons, click on gigapan.kml and check that out [you will *always* see one of Payam's GigaPans] :) As an example, fly to 77030, move slightly west to Rice University and there are all of my GigaPans of Rice :) See the power that having your GPs is GE now afford to you?

    Geocoded now.

    I've "placed" it in Google Earth. If geocoding is something more I'll have to read up on it.

    This is some serious stuff that you have here. Next time you do something like this, you should take a video and U/L it to youtube.com and let Illah know about it. I would certainly want to watch a demonstration on how to accomplish all of this that you have done, but a closer reading indicates that the real work was in PhotoShop. Are you going to geocode it? I have bookmarked this GigaPan.
