And are you looking to go with a publisher or do it yourself?
I wrote and published a short story in 2003 (unrelated to photography). Went looking for a publisher, was told there wasn't a market for my work, so published it myself. Wrote and typeset it, paid a designer to do the cover illustration, got an ISBN number from NLB and sent the artwork to a printer. Mind you, I had over a decade of experience in DTP and prepress work at the time (I still typeset an occasional book), so all this was well within my general job scope. Marketing it was an entirely different story.
NLB has a good deal of information if you're self-publishing - Deposit
Sorry to dig out this thread but I know of a photog in the US who has done one using kickstarter as an aid to get the initial publsihing budget. Her book is called Project DOG You can see more and contact her via https://www.facebook.com/projectdog
We've published 2 relatively substantial booklets and 1 very small booklet
1 of them is on sale at BooksActually and Basheer.
Printing costs in singapore are crazy, and breaking even on them is tough. So if you're intending on making money from book smake sure you already have a list of people who want to buy it.
Apart from that it's enormously satisfying to get a book printed.
For smaller print runs you can look into digital printing (less than 1000 pieces)
