I still haven't figured out how to upload photos directly from the iPhone. There is a free app for Wordpress but none for Blogger.
I have edited today's picture with the PhotoBox app on the iPhone, it is not quite as convenient to use as Mill Color but does not resize the images. The post is written and published on the iPhone though.
Other than the Lomo and Holga look and feel, I wanted the picture to look a bit like from the 70s with the same colors.
