Martin is right, but only to a degree......Sorry Martin..For images as he has taken the macro works well. These images are flat. They have no depth, but on Macro setting the image depth of field can be a couple of millimetres, therefore throwing most of an image out of focus, which is fine in artistic terms, but not in our hobby, where we are trying to show details in focus.
For best results we want to set a largish aperture, say f8 to f11. Shutter speed is not important if mounted on a tripod and shooting a static image. Focus as close as possible to the image and use flash if required. Then only a small amount of cropping will be required to show the detail wanted. If the finished image is too large to post, then it will need resizing, but then that has always been the case..
Such an example is shown below.
