The little details add up, and when most travellers return from a trip they talk about the highlights and often don't have time to describe those little things that create an overall impression. Smell, for example, is not something I can describe easily and expect to have an interested ear. Detail is a prerequisite for creating a believable scene in a work of art, even for a children's book. The audience will take to it better, and engage more deeply in the story, so long as the facts don't get in the way of the mystery, the story and the action. I take dozens of photos every day and spend a good deal of time editing, filing, reducing their size, and picking my favourites. I make notes about what I've missed. I have three digital cameras with me, of which the small red Canon Powershot is the one I use most frequently.
