HDR Images with Qtpfsgui

Blossoms near estuary Malahide Castle woods photo

I've been experimenting with tone mapping RAW images with the Qtpfsgui OpenSource tool. It's always difficult to get the sky and foreground things (like spring tree leaves or cherry blossoms) to be simultaneously exposed properly. In the chemical photography days, you'd have to dodge and burn in tiny areas of the photo to properly compress reality's tonal range onto the limited dynamic range of paper prints. I'd like to build Qtpfsgui for OpenSolaris, but it looked like the GNU/Linux versions depended on a particular development environment. Now I see that some versions seem to have been built with cmake which is portable to OpenSolaris. I'll let you know if I figure out how to build it.

Hi Brian,

I built qtpfsgui on opensolaris a while ago. works quite nice. i should rebuild the stuff using spec files and pkgbuild i guess. only thing is you need to build everything with gcc though...

To Bernd; Could you get that into pkg.opensolaris.org somehow ?

Thanks,
Edward.

yeah sure... i'll try to put it all together over the next days.

I just put SFEqtpfsgui.spec into the repository. Only one thing: we need SFEexiv2.spec which seems broken right now (I informed moinak). It needs to be build with gcc but tries to build with Studio at the moment. Also I used qtpfsgui 1.9.1 as 1.9.2 is broken (can't save hdr images).

give it a shot and let me know how it works please.

Bernd and Edward,
It's great to hear that so many others are interested in porting even these oddly named specialty applications. Thank you for building this and arranging to put it in the package repository! I'll try it out next time I have a spare moment. BTW, unless the application is huge or you have to build all of the QT dependencies with gcc, it's usually possible to make it build in sun studio. Sun Studio's default (unoptimized) build may be slower than gcc's default, but when optimization is enabled in both, Sun Studio can be considerably faster.

To make things easier (for me ;-)) I used the available spec files for openexr, ilmbase, fftw, exiv2 and qt (i think that are all dependencies). all c++ stuff built with g++ (which is all but fftw). i haven't found a way to build exiv2 with studio so the whole bunch has to be built with g++ for now. i'd love to get this (and a few other things like digikam) built with studio for better performance. but i lack a little knowledge of c++ to port exiv2 and co :-\\
