Re: [hugin-ptx] Re: Hugin: How to build an HDR Panorama from bracketed images?

I do mine in 48-bit TIF, which is 16-bit per channel RGB. 48-bit color is my DSLR's native depth. Real HDR is done using multiple frames, shot at various exposure ranges so the darkest exposure gives you no clipping at the dark end, and the highest exposure gives you no clipping at the bright

Re: [hugin-ptx] Re: Hugin: How to build an HDR Panorama from bracketed images?

Roger, I'm not sure things are as drastic as you make them when you say "What is needed for HDR work, is either a floating point format (about 12 bits per channel, would be sufficient, but 32 bits per channel are normally used in hugin) or a high-bit-count fixed-point format." Yes, to get the b

[hugin-ptx] determine heading from sun position.

Hello, ever had trouble to find correct heading for your panorama? If it is shot outdoor the sun might give you an exact value. One or the other might know of the possibility to use wolfram alpha to calculate the sun position for given GPS coordinates and time. Since entering all the values

Thanks Rogier, I think I must study more those details of image formats. These information you told us have clarified my mind a little more. Do you recommend a good general reference about it? And you are right, I fix the exposure bracketing for the whole panorama and as I use a manual workflow in

Re: [hugin-ptx] nona interpolator in hugin 2012.0

If you used the same kind of input images that I saw in your test zip (heavily compressed JPGs with a size of only 769 x 1024 pixels each), then no, I don't think you will see a big difference between these interpolators. Do you really shoot at 769 x 1024? Does your camera support Tiff or Raw?

Guys, when you say "24 bit jpeg" almost everybody thinks of this as "full color (RGB), 8 bits per channel". What is needed for HDR work, is either a floating point format (about 12 bits per channel, would be sufficient, but 32 bits per channel are normally used in hugin) or a high-bit-count fi

Hi, just to clarify, I don't work with 24-bit jpg. I usually shoot in JPG and work with it in 8 bits. But alit_image_stack can deal with tif and you can work with tif all the time. I just put JPG in my example because I use it :) I sometimes have some ghosts in the final result of the enfusion, b
