PhotoDemon 6.0 is now live at

PhotoDemon 6.0 beta is live

It's taken nearly six months, but PhotoDemon 6.0 is finally ready for release. I've already talked about some of the great features this release includes, like powerful selection tools, EXIF and other metadata support, Curves and other new tools, so I'd recommend glancing through the linked article if you're curious. Since that article was written, a number of other features have been added or improved... (read more)

About Tanner


I'm a bioinformaticist by trade. For most of my career, that skill set paid the bills while I used my evenings and weekends to write books, compose music, and work on a variety of open-source programming projects. Eventually - and fortunately - I came to the realization that while I greatly enjoy science, my heart lies elsewhere, so in 2011, I quit my job and took up writing full-time. The plan for 2013 is to find a publisher for my latest novel (fingers crossed!). In the meantime, I use this site to collect my many side projects, which I hope is more useful than hiding them in an obscure desk drawer.
Kind regards to all.   ~Tanner
