Observation 25872: Helotiales Nannf. ex Korf & Lizon
When: 2009-09-27
No herbarium specimen
0 Sequences

These are very small – approx. .030" – .045" (about 1/32")

I had to jack up the contrast in the upper midtones and sharpen more than I like to bring out the structure.

Seems like anything bright yellow is awfully hard to get with a digital
without the yellow being oversaturated. Indirect light needed for sure,
I got a few shots through a hand lens here: http://mushroomobserver.org/13818

They are challenging- all that yellow masks the detail

I brought mine indoors and used a 1:1 macro lens with an extension tube to get the magnification (on a tripod). I think that lighting is the key. I used a flash, diffused through a plastic bowl, directed down at about 60 degrees. I bet with less diffusion and a lower angle the structure would be easier to see without all the postprocessing. Next time…

Use a Canon Powershot A480

With that and the correct configuration of the camera beforehand, and a tripod, I took this photo: http://www.mushroomobserver.org/image/show_original/58288

No postprocessing, save anything that MO may do to uploaded images automatically. (So far as I am aware, that means nothing; if you download that and view the EXIF metadata you should find the fact of its being taken with a Canon Powershot A480 specified, along with a bunch of stuff about focal distance and lighting conditions. To save the bother: ISO 80, a bit more than 1 second exposure, nearly point-blank range, in indirect sunlight, no flash or other artificial light used. The low-ISO-long-exposure combo gives a nice bright image with zero noise, but the camera must be extremely steady (tripod) and depth of field isn’t enormous.)
