What a lovely collection! I like your approach, using the random vintage effect with a set form of framing.

My one wish for the app would be for it to write its settings somehow into the picture's metadata. That would make it much, much easier for me to learn to use it (you know, look at a set of pictures afterwards and say, "Hey! That's a nice effect! What was it?" Similarly, looking at your pictures, for instance, on Flickr, it would be helpful to see what effect you used to produce them.)

As it is, so far I've discovered that the Ilford black and white and the Platinotype settings are very much to my taste for a lot of kinds of pictures. The rest, I'm still trying to get a feel for.

So much fun for so little money. Amazing, isn't it?
