Backyard Springtime Nature in New Jersey.

May has been cool and rainy. It was warmer in April this year. While it has been cool I have been able to expand the sections for my wildflowers. I didn’t spread any new seeds in the 15′ x 30′ section on the east side of the house planted last year to see which perennial, biennial, or self-seeding annual wildflowers would come back. This morning when I got up, it was way too bright outside — the sun was out!!! In addition I noticed the first red poppy flower for this year. Coincidentally, the American Legion has recommended that the Friday before Memorial day be designated National Poppy Day. In the Commonwealth nations, red poppies are used to commemorate Remembrance Day (11-November).

Photography Techniques — Focus Stacking.

I have been using Helicon Focus to make composite focus stacked images for several years. It is great for doing macro images with much more depth of field than can be done with single images. I spent the day doing some focus stacked images on some small cactus flowers. The images were taken with a Nikon Df camera and 105 mm f/2.8 VR macro lens. The camera was set up on a tripod on with a linear tracking head. The first set was with 13 images, in 5 mm intervals — which wasn’t enough. The second set was 24 images over 9 cm. That one looked better. I then added a TCE-3 III teleconverter (converting the focal length to 210 mm). The camera was set closer and did 33 images over 9 cm. The slide-show below shows all of the images. It includes one image from each set at a single distance. To see the individual images check here

Backyard Springtime Nature in New Jersey.

After several days of cold, cloudy skies, and rain things cleared up for a bit. The clouds turned pink at dawn (only for an instant). Later on I saw a robin hunting in my backyard. It found a caterpillar for breakfast. One less butterfly this year… (check out a similar image from three years ago 03-May-2014). I took a cluster of rhododendron flowers inside to practice focus stacking. It was too difficult outside with the wind moving the flowers. I used a 9-cm focus rack. For the first two, the images were taken after adjusting the camera in 0.5 cm increments. For the third one, the camera was adjusted 6 cm in 1 mm increments. The images were processed using Helicon Focus (ver. 5.3) software. Let me know if you like method A (weighted average), B (depth map), or C (pyramid) for processing the images

Early purple crocuses flowers from across the street. This is a composite of many images using the focus stacking program from Helicon Focus. A little bit bright, and requires calm conditions (little or no wind).
