Wow...fantastic. I'm pleased for this on several levels. First, as an American that grew up in Berlin for 8 years, I have a soft spot for the city. As an RFFer, I have a soft spot for rangefinders and analog photography 🙂
It's also encouraging to see someone selling some books. Thus far I have only done mine via blurb, but I envision that being the first step to getting them printed and selling via my website. However, I'm never sure what kind of a reception I'd get. Finding constructive critiques is difficult online and I'm never sure if the lack of responses is due to apathy, dislike of my work, or what. So that's good to see.
I took a quick look at the website, and I'll order a copy when I get home tonight. If nothing else, I like to support fellow amateurs (and RFFers) who are getting their work out there. I know how much work it takes to put a book together.
