My Photography geared customization of Ubuntu, which I so creatively called Ubuntu Photo, has been listed on Softpedia. A bit of an unexpected, albeit pleasant surprise! You can find the link here and see their brief write up.
I originally had a base system geared toward general users, but have since decided to scrap that and focus solely on my photography geared version. Long term I would like to further my customization beyond the default fall-back mode and extra set of applications.
I would also like to do a customized Xubuntu version, but it will take a bit more research on the customizations with XFCE as Remastersys does not keep all the user customizations and the desktop stays the same as the default Xubuntu (that I am not wild about).
