Well, at least I make enfuse do this as I make the output from it in a 24-bit RGB JPG. Yes, you can do that. I prefer to end with 16-bit TIF. Surely more information is capable of giving more quality and maybe in some situations I would see some better results, mainly if I use it in the intermediate steps. As far as I've experienced until now I don't even see much need to use raw shooting. I've already tested it some times and when I am shooting a hard scene I shoot raw, but in 90% of the cases I am pretty much satisfied with shooting and working with 24-bit RGB JPGs. On some images now, I finish by pulling the 16-bit TIF in Luminance HDR and tonemap the image. I usually only publish on the web. I have already printed some pictures in fine quality and thought that there it could make more visual difference for me, but at the computer screen my poor eyes are satisfied till now :) You can't really see HDR on display screens or prints, because high-dynamic range means wider dynamic range than display or print technologies can reproduce. HDR is for all of the processing up to the final output. I prefer TIF for that, too, or PNG, just because even at 100% quality, JPG loses color information.

Re: [hugin-ptx] Re: determine heading from sun position.
Oh, the trick is so cool I used it as soon as it was mentioned by Kay here on the list. It's perfect to calculate the heading of a panorama if you publish it on 360cities.net so links to other panoramas point in the right direction, like here: http://www.360cities.net/image/seinskopf-peak-above-isar-valley Kay's trick works great here, and I really like Erik's approach of including the wolfram search in an exiftool command. Exiftool can write the coordinates e.g. from a simple GPS logger in your images, and it's very fast. In another case when the sun was in the clouds http://www.360cities.net/image/zugspitz-gatterl-connecting-reintal-and-ehrwald-the-easy-way-germany I needed another approach: I knew my panorama's coordinates and spotted a well known hut somewhere in the distance: http://en.wikipedia.org/wiki/Knorr_Hut. It was easy to find both in Google Maps and then calculate the angle from a screenshot. Carl Carlos Eduardo G.

Re: [hugin-ptx] Use of Hugin in remote sensing
Ok, I will try that. I don't really get why I fot those crazy values even with the new enblend. The funny things is that if I create the mosaic with all the pictures 141 pictures I get those crazy value. When I create it with just 131 pictures i don't get them even though the area is covered. I join a screen copy of the same area. -- You received this message because you are subscribed to the Google Groups Hugin and other free panoramic software group.

Re: [hugin-ptx] Use of Hugin in remote sensing
Well I compare really carefully the source images and the final one, it seems that nona and enblend change the value during the process so all of this was kind of useless since I need my value to stay the same.

If you don't want the values to change during blending then maybe you need a simple seam without any feathering, try using an enblend -l 1 parameter. This will do a basic hard-edged montage.

Re: [hugin-ptx] Use of Hugin in remote sensing
Well sorry as non-english speaker it's pretty hard to make it clear. i have many Tiff files with temperature information and I know that they overlap since they are extracted from a thermal movie carried on a plane. So my aim is just to past the images together without any change to the value since they will be the base to some really accurate analysis. It seems that nona as well change the value however I will try the -l 1 option in enblend and see if it works. The problem of Grass is that I need coordinates for that, my final image will be georeferenced afterwards but for the moment they don't have any geographical information so i can't use any GIS tools Thanks again and if you have a magic option for nona to avoid the change of the value i would finish this crazy project! -- You received this message because you are subscribed to the Google Groups Hugin and other free panoramic software group.

If you can georeference afterwards, then you should have enough info to georeference each image prior, then patch them together in GRASS, but that does require a bit more work. If you can't stitch in hugin without any change in pixel values, then you may well have to resort to the above approach.

It seems that nona as well change the value however I will try the -l 1 option in enblend and see if it works. I don´t remember if you already told how you got your images. I mean: are your individual pictures a copy of the movie frames? Do you know some parameters of the lens used to make the movie? As Hugin uses the lens geometry (image distortions, etc) I seems sensible that nona could change yor values, as nona generates images projected on a sphere (for panoramas) or over a plane, for mosaics -- which I guess is your problem: a planar surface with a field of temperatures. [post note: I just checked your first message and you told us about /a temperature raster mosaic/]. Have you seen http://hugin.sourceforge.net/tutorials/scans/en.shtml already? Did you create the control points by hand, or with cpfind or other automated methods? Your hot surface has enough distinctive features to select as controls points? I apologize if those questions are already answered in previous messages...

[hugin-ptx] What's the status of the gui update?
Hello All, There hasn't been a lot of discussion of late about problems with the gui update. I have been running a gui update version for a while now, and it seems to be OK for me. I guess I am getting used to it, and perhaps my projects are relatively simple, but I haven't run into difficulties that haven't been able to be overcome by a bit of 'education'. If it is considered to be what we want, and close to sorted, I might start putting a bit of time into revising tutorials ready for when we release with the new gui. The question is, are we close to finalising the new gui? Cheers, Terry -- You received this message because you are subscribed to the Google Groups Hugin and other free panoramic software group.
