Pink Flower — Macro and Wide Depth of Field. I used the pink flower from yesterday as an exercise to practice with a macro lens, flash, and Helicon Focus to get a macro image of a flower with an extreme depth of field in focus. Ten images of the flower were taken from rear focus to front focus by manually adjusting the focus distance on the lens. The raw images were processed with Capture One Pro, converted to 16 bit Tiff files, and then processed with Helicon Focus. Even though the lens was set at f/22, the actual focus plane was very narrow and thus needing several focus distances for Helicon Focus.

Can You Identify this Shrub with Pink Flowers? I have been told that this is a Mountain Laurel, however when I search the web the flowers do not seem to be the same. It blooms in early spring, and the deer also avoid it. If you know what it is, please let me know. I need to get a better image with a macro lens.

First Dandelion of Spring. I noticed this spot of yellow in my driveway when getting home. An early dandelion — I’m sure many more will show up in the backyard soon. The local deer avoid eating dandelions and daffodils, but eat most any other spring flowers.

My Taxes Have Been Filed. Now the crabs can come out from hiding, and I can start working on my images again! Image taken one year ago while on a Photography Workshop in Big Sur on the Central Coast of California.

Digital Editing — Comparison of RAW Image Converters. Something a bit different. Today I am comparing 4 different programs that convert the RAW digital images acquired by my Nikon cameras. The RAW converters that I typically use include Adobe Camera Raw (ver 6.2), Nikon Capture NX2 (ver 2.2.6), Phase One Capture One Pro (ver 6.00), and DxO Optics Pro (ver 6). The programs were all run on Windows 7 (64 bit). The image was taken with a Nikon D3x camera and 14-24 mm f/2.8 lens (ISO 100, 14 mm, f/16, 2.5 sec) on a tripod. The overall scene was beyond the dynamic range of the digital sensor. It was rather dark in the forest, thus the long exposure. The bit of sky visible is bright (and blown out). In the following days I will be comparing some HDR (high dynamic range) programs to process several images of the same scene taken at different exposures to try to compensate for the wide dynamic range.
Adobe Camera Raw. This is the program that Adobe uses to process RAW digital images for Photoshop and Lightroom. Camera Raw is only able to read some of the Nikon in camera settings. In recent versions they have included settings that simulate the Nikon Picture Control settings (Landscape, Vivid, etc). The current version of Camera Raw also now includes lens corrections for a wide variety of lenses including the lens that this image was taken.
