First of all: Darwin, sorry for your loss. Times have been tough for you and yours, take it easy with the postcards, that should be the least of your worries.
Now, so far I have received three cards:
Mark_S, detail of a Victorian house. Nicely framed, lots of different details to observe. Very nice.
TXFZ1, Cathedral Spires, that's some nature you have captured, there's none of that in my flat country. Love the detail of seeing the water flowing. The great outdoors. Lovely.
Pelo78, SF Twilight at the beach, beautiful how the playing kids turn into ghosts due to the slower shutter speed. That really makes the picture. One would almost forget to look at the background, which would be a shame. Very nice.
Off to a very nice start, I would say.
I have been out and about with the camera, shot two rolls of 6x9 (I'm more used to 6x6 and 6x4,5; with 6x9 rolls fill up pretty fast!), and developed the first of those. First roll of film developed in my new house, hooray! I hope I can select one or two shots after developing the second roll, and then... I hope my cyanotype chemistry is not too shaken and stirred from moving house. In other words: it will be a few weeks before I can send my cards.
