I alway shoot in the RAW format. I makes shooting kind of sketching; just the outlines of the composition and the subject are important. With the latitude you’ve got with shooting RAW, adjusting the picture to your liking is something you do in post. However, when I recently got invited to a photo contest, I was forced to shoot in Jpeg because you had to deliver the photo’s at the end of the day to the jury. It forced me to take some test shots with the M9 around my apartment the day before. I actually like the result and have set my M8 (which is known for its excellent B/W pictures, hence its name “poor man’s Monochrom) and will take it out for a test-drive soon.
