December Frost

Last month I posted about morning frost and shared a few photos. A month later I got out again to reprise the idea and wanted to share them as well.

The color is slowly seeping from fallen leaves so I converted these to monochrome in Lightroom 4. For most black and white conversions I also like to crank up the “clarity” setting to add mid-tone contrast.

I’ve also been experimenting with focus-stacking over the last few years and several of these images use this technique. They comprise 3 separate images all focused at a different point and then combined in Photoshop’s “Auto-Blend Layers” command.

Macro photography means a highly-compressed depth of field, so the ideal aperture of around f/8 (which is usually a lens’ sweet spot and yields less diffraction) is not always practical. I compromised sharpness just a bit to gain a larger depth of field (smaller aperture) and hoped that Lightroom’s sharpening controls would compensate. That combined with the focus stacking worked fairly well.
