     Krita?

    Have you thought about adding this as a plugin or similar to the upcoming krita? I know that the krita developers are thinking about including tone mapping support and would be happy to see any help there.

    I didn't know about that. I'll try to remember to give them a holler. They could also help me diminish the memory footprint.

    when i open tiff which is made from raw. the program erroneously determines or reads it in the tiff that EV=-6 for all files. The problem is it cannot be adjusted (corrected) manually!

    Also unfortunately it constantly crashes or hangs in tonemapping :(.
    It seems more prone to crash if I click apply quickly after changing some parameter, but not only.

    Same problem with the tonemapper in OpenSusue 10.2 (32-bit):

    ::::::original goes into resize
    executing resize step
    executing pregamma step
    executing tone mapping step
    Segmentation fault

    I tried RPM and also self compiled package.

    Any idea for help?

    New version 1.8.10 works on SUSE 10.2

    you can find it here:
    ftp://rauchs-home.de/suse/10.2/i586

    you need to install libexiv2-0.11 first.

    if libexiv2-0.11 conflicts with other versions of libexif, install it with "rpm -i --force ...", it doesn't matter to have different version on the same machine.

    best regards

    Please add saving result in 16bit.
    Does the current png option save it in 16 bit? Thanks.

    Very promising program. Please keep developing great app.

    1) if the checkbox is grayed-out and you cannot specify any value manually, it means that Qtpfsgui is using the correct values from the exif data in your image.
    In that case there is no need to specify the exposure values manually, Qtpfsgui is already using the correct ones automatically.

    2) Yes there were several bugs that crept in (especially in the windows version) but with the latest version (1.8.8) all of them have been fixed.

    3) Saving a tonemapped LDR in a 16 bit format makes little sense (to me, at least) :)
    Here's a discussion we had a while back on flickr:

    This works only in ideal world... Yes. There is a need to specify values manually because exif values can be incorrect even if the program reads those incorrect values correctly!

    2) Yes there were several bugs that crept in (especially in the windows version) but with the latest version (1.8.8) all of them have been fixed.

    I meant 1.8.7 linux version.

    so the operators produce 8 bit output... ok.

    1) qtpfsgui provides a one-to-one exif data copying feature, maybe that can help you cope with that problem.
    I'm curious, how is it possible that the aperture value and the exposure time info in the exif data can end up being wrong??
    Another workaround is to use a different application to erase all your exif data (qtpfsgui doesn't have that capability).
    Just remember that if you are dealing with only one image then you can set the EV value at an arbitrary level, the histogram will only be translated left or right, you can find the mathematical reasoning here (pretty hardcore stuff):
    http://freenet-homepage.de/hsbosny/HDR_Tutorial/HDR_Tutorial-en.html#Bemerk_1

    2) Does it still crash with 1.8.8?

    1. Of course it is easy to screw up exif. In my particular example tiff files apparently have wrong exifs after output from raw covertor. Of course I now always have to set in the raw converter to not export exif if I intend use qtpfsgui and after that I always have to set it back as it also affects jpegs output (for jpegs exifs work fine). Very inconvenient.
    Why not to read the exif and also make comboboxes which set this "alive"? This seems very natural.

    2.Thank you! It does not crash anymore.This is great.

    This program rules in every way: features, interface, full GPL, and sourceforge trackers.

    Thanks for a great program..

    How do you like Plasma 5?
     The best KDE Desktop ever.
     Definitely a nice improvement.
     Not decided yet. Haven't tried it yet.
     I do not like some of the changes.
     KDE is taking the wrong way.
     I am still sticking with KDE 3.5.
     I have no opinion, but wanted to vote anyway.
