So while it still early Spring in Illinois, we're still stuck with the early blossoms, mostly daffodils and tulips around here. Even the dandelions haven't bloomed yet! But we do have a good patch of grape hyacinth in the yard south of the house. The patch is definitely larger and denser than last year, so they must have enjoyed the hard winter! The image at right is taken with the macro and tripod, and shows about 1" (about 3cm) of the blossom. Each of the largest "grapes" are about 1/8" (3mm) across.


lately will likely know that the right image was put together from a set of "focus stacked" images. Eight pictures were taken as the focus was moved between the front and rear part of the flower and combined into a single image in Photoshop. Enter "focus stack" in the search box at upper left to find my earlier posts on the subject and to find the video tutorial I used to learn the process. Shown here at left is the same image as above at full-camera resolution. Taken at a wider aperture of F/6.3, the exposures can be shorter (160th second at ISO 400) and you retain the higher resolution, though narrower depth of field of the larger opening. Most would ask, why not just stop it down for greater depth of field? Well, shown at right is just that - exposed at F/22 for a 16th of a second, and you can see the resolution (again, shown at full-camera resolution) is lower. Whether it is due to the 10X longer exposure or pure diffraction from the smaller aperture, I can't say. There were some breezes, but I was waiting for quiet moments for all these shots... It looks to me that focus stacking wins hands down!

Our neighbor Elaine has a patch of daffodils I was attracted too, and the macro moved in to the central part of the flower for the view at left. She has quite the assortment of flowers, most blooming later in the Spring and Summer. The peonies were out of the ground, their buds formed, though we'll miss the gorgeous blooms in a month or so... You can see the bud being attended by ants - they always seems working hard on peonies, and I learned today that they actually have no role in the bloom mechanics - they are only attracted to the nectar emitted by the bud. The mistaken assumption they are needed for blooming is a myth!


While we've got a few more days here, dramatically warmer weather isn't predicted, so I don't expect too much more excitement to photograph in the springtime venue here, but will keep an eye out!
