A new PhotoFlow version has been released today. While this comes shortly after the release of version 0.2.1, the addition of an RGB histogram and of a new interactive gradient editor (very handful for example to create transitions in multi-exposure landscape shots) definitely justifies a new release!
OSX and Windows installers are available from the github release page, and more details can be found on photoflow’s blog.
Disclaimer: uninstall the previous version or the new package would not be installed (I don’t know why, but I told that I was really really bad with pkgbuild)
