Yes Keelin, I played around with opposites when the opportunity struck. A back ground of a light stratus with little dark shreds of cloud being tossed about by the wind looks easy but getting enough contrast for everything to work is difficult. That series of shots probably demonstrates an edge to some of the limitations or parameters of digital photography. Low contrast makes auto focus difficult. True, the manufactures are developing other ways or improved ways to focus digitally than the existing ” contrast between pixels”. But I don’t have the latest technology camera. And if I did, it’d be obsolete in 6months anyway. Talk about harvesting,this Fall Nikon and Canon are supposed to announce their new ” mirrorless full frame” cameras. Can’t Wait!

I like the cloud flow of your shot as well Keelin . Your ” Here” could be anywhere by now.

Hello Ramona, Nice capture with the camera, but no, imho, what you’ve photographed isn’t AltCum lacunosus. I believe you caught deteriorating altostratus or even a lower stratus. My understanding of the difference between lacunosus and deteriorating stratus is,,lacunosus is formed when colder air drops in altitude..the key might be..” forms”. When stratus deteriorates,,it is coming apart, evaporating back to gaseous state when warmer atmosphere rises through the stratus. Lacunosus condenses out of the atmosphere, forms. What I’ve seen is usually a uniform altitude, or sheet of lacunosus. Deteriorating stratus or even deteriorating lenticular is pushed and rounded as the cloud evaporates from rising thermals. The gallery has examples of lacunosus. My experience has been that lacunosus has no real herald, nothing hinting at its entrance. It just happens. Only a few times has it been literally out of a clear blue sky. Most of the time lacunosus has been part of a hurly burly mix of a system sweeping though. Most of my observations have been of small to medium patches of sky especially at alto altitudes. Tip of little finger to tip of thumb of an outstretched hand ( or less) is a small patch of cloud to me. That distance is also roughly 20degrees a way to measure halos distance from sun, and for star gazing at night. When you see Lacunosus you will know it. Look for a uniform horizontal sheet of it, maybe even under a thin asperitas event. Have fun!
