Forced because missing manual in French in carton The author is very pleased with himself (I know, the others are zero etc.). Inconvenient: you have to go from one chapter to another to have complete information about a topic. For some items it is not explicit (ok 3 but which to choose image size and why?) I'm not new at this photo and despite this supposedly great book many functions remain unexplained or abstruse way. I regret my purchase is the dressing.
