This one is here to prove that last night we had some snow fall upon us, this afternoon the gloom lifted a little so I thought I would go out the back of the house and see if I could persude the Sony to a couple of last reasonable images. as it happened the sunny vanished before I got to anything worth looking at, and the pictures were all blurred and dark so I reverted to trying infill flash, going through a whole series of settings of both flash and camera and distances between the subject and optical zoom.
I ended up with the camera set im mannual F8.0 @ 1/1000sec a setting I have found works quiet well as a defalt daylight flash setting. I stood about 75cm away from the branch and zoomed into 14.9mm (this image is a 50% crop of that image), and my fingers forming a slot across the flash to cut down the amount of light spread even with the flash set on low level.
Xanthoria polycarpa the lichen seen here establishing colonies in the angle of the small twigs of a Guelder Rose Shrub (Viburnum opulus) a native hedgerow plant this particular lichen likes growing on bark see these previous posted images.

Adjustments
Open image
Burntool at 9% and a soft edged brush to darken some of the highlight caused by the flash , even though the flash strenght was controled in several ways.
Crop to size about 50% of original
Shadows and highlights, mainly to releave the total blackness of the BG caused by the flash also.
Sharpen with USM
resize image to 800pixels at 72dpi
use Save As to down size the file and also preserve the exif shooting data so you can veiw it on the left.
post to site and hope you enjoy veiwing it as much as I did putting this together ;0))))
