Modus Operandi

For the curious here is how the pictures were made. Photographs were taken with an Olympus E-M5 II camera with a 60mm f/2.8 Macro lens stopped down to f/5.6 for sharpness. The "one light" was an old lamp that was gathering dust in the garage. Marketed as a Day-Light Sky Light the color temperature was measured by photographing a white balance reference card. The color temperature was 4300K with a tint of 53 as indicated in Lightroom. Applying this result to the remaining images made a big difference in color accuracy.

For most of the images the camera was configured to shoot with Focus Bracketing turned on, Focus Differential 3, and the Number of Shots 20. This feature uses the electronic shutter to take a series of 20 images varying focus for each image. It assumes that the first shot is the closest and slowly focuses further away for each successive shot. The amount of change is determined by the Focus Differential which varies from 1 to 10. The Differential takes into account distance, focal length, and aperture of the lens so that the amount of focus overlap is consistent regardless of these factors.

After focusing on the closest feature I manually focused slightly closer before releasing the shutter. Usually only 7-10 shots out of the 20 were used. Images were imported into Lightroom where they were culled to select the ones that applied to the flower of interest. Then they were exported to Zerene Stacker and blended to produce the final image. Nothing like specifying your depth of field during post-processing!

Oh, and here is the Peniculus Dentarius. Those little yellow thingies bang against your gums to stimulate circulation. Well, that's probably more than you wanted to know!
