Experimenting with Focus Stacking

With the not so lovely weather we have been having I have had little chance to get out with the camera since Christmas, so I decided to experiment with focus stacking using still life images.  The idea is that instead of using a small aperture to get decent depth of field you take several photos with different parts of the image in focus in each then merge them using Photoshop or similar software.  This way you should get all parts of the image in focus and really sharp.  It took me a while to get the software working and getting the focus right is a bit of a challenge but these are the results....  I am sure I could do better with the focusing on every part of the image but it is surprising how little you need to move the focus ring when zoomed in like this.  Now all I have to do is try it out on a landscape.
