How many photos should be kept?
This is a personal question and it will vary tremendously. Some situations like fast-moving actions often get a higher hit-to-miss ratio, so there is no universal answer. Remember that Delete is your friend. It is good to delete anything that is not technically perfect with extremely few exceptions and then delete anything that has no point of interest or is too similar to another shot. This will make it easier to find nice pictures and create high-quality galleries. The most common reaction to this advice is that storage is cheap and, while true, the cost of managing storage is not.
