This is the 15th year of continuous daily publication for 365Caws. All things considered, it's likely it will be the last year as it is becoming increasingly difficult for me to find interesting material. However, I hope that I may have inspired someone to a greater curiosity about the natural world with my natural history posts, or encouraged a novice weaver or needleworker. If so, I've done what I set out to do.

Darkfield
Day 27: It occurred to me that I hadn't properly introduced Darkfield to my readers, so with today being another Pacific Northwest Classic (i.e., rain and gloom), I grabbed a little botanical material and some of the tools of the trade to keep him company in this presentation. Darkfield microscopy employs a special condenser below the stage to focus light in such a manner that that which is directly transmitted does not enter the objective, only scattered light from the specimen. The specimen appears on a dark background rather than the bright field seen through a standard microscope. Specimen features invisible in brightfield may become visible in darkfield. The darkfield 'scope is definitely a step up for me, and since I bought it, not a day has passed that I didn't use it to examine something.
