This HDR went a bit wrong, so I rescued it with Toon Paint. I liked the composition. Sadly, I think I mangled the image quality by using such a long workflow.
PictureShow has had a big update. It’s iOS 4 ready now, with all important retina display support, and has a much better looking and more intuitive UI. It seemed a little quicker too, and will let you save full sized images. I only noticed one new frame style though, and text alignment doesn’t work. Still, it is perhaps the best post-processing app for the iPhone.
