Depth of field is often a problem with macro photography and even when we use a very small aperture it's not possible to get all of the image in focus. There are times when it's lovely to have part of the image in crisp focus and the rest of the photograph blurred, but there's also a technique for those occasions when we want the whole of the image pin sharp. The example below is a shot I've been working on of bluebells just after a rain shower.
