Re: [hugin-ptx] Help My Skies
Carlos: Thanks so much for taking the time to respond. Your tips will help me out. I do play with masking a bit but I wouldn't call it methodical at all. I kind of do a hit-and-miss approach as I have little skill at it. Occasionally I generate improvement with masks but usually not. I haven't tried using other images. I'll give that a try. My PS skills improve with every pano I make. However, I have a long way to go to fully use the capability of the tool. Thanks for the image editing pointers - they will help.

Re: [hugin-ptx] Help My Skies
When using other images notice that you can repeat the same image as many times as you need and do masks so that only the sky on it is used. Another approach would be to substitute the whole sky for another... a sky is a sky :) Cheers, Carlos E G Carvalho (Cartola) http://cartola.org/360 http://cartola.org/panoforum 2012/6/11 Calvin McDonald c...@ckmcdonald.com Carlos: Thanks so much for taking the time to respond.

Re: [hugin-ptx] Help My Skies
In the upper areas of an equirectangular image the information is so compressed that it's not easy to use clone tools etc. Usually it helps to reproject to cube faces which have a rectilinear projection and cover 90 x 90 degrees. Especially for the zenith (also the nadir) that helps a lot! So with Hugin, you can load your equirect back into a new project as your input file (lens type: equirectangular, 360 degrees hfov). In Images tab set pitch to -90 degrees (in the Fast preview window you can now see the zenith in the center). In Stitcher tab set projection to rectilinear and fov to 90 x 90. Press calculate optimal size and stitch. With the original panotools this could be done in Photoshop but I bet this would also possible with Kays Python scripts, right? Here is a HowTo for the nadir: http://panospace.wordpress.com/2008/03/18/edit-the-nadir/ Here is more about it in the panotools wiki: http://wiki.panotools.org/Extracting_and_inserting_rectilinear_Views Cheers, Carl Carlos Eduardo G.

Re: [hugin-ptx] Help My Skies
Yes, I also use erect2cubic, but to have it you need to install Bruno Postle's Panotools::Script http://search.cpan.org/dist/Panotools-Script/. If someone need it for windows I have it already compiled as a portable version.
