Fly feeding on a dustbin lid. Pic is focus stacked from 2 shots. Like the smiley face on the end of it's tongue. Taken with a sigma 105 and 68mm of extension tubes
60 or so images using zerene.
used my 200mm all the way open with a takumar 55mm reversed on the end @ f8 i think.
only have my incam flash, so i have a tube reflecting it past the end of the lens and down.
Last week I spent an afternoon trying to get comfortable with focus stacking in the field. It was an ideal day with cloud cover and minimal wind. I will post some of the images from the outing in the next few days in pairs.

Each image focus stacked from 5 pics.
stare at pair slightly defocus and cross your eyes until an image appears in the middle and then try to relax your eyes to lock the 3-D image
This was made with the Olympus 'Focus Bracketing' function. 20 shots were assembled in 'Helicon Focus' - the result is nice... :)

It seems like eating strawberries in mid-winter to have tulips in February – but these flowers are, of course, available in the shops, so I couldn’t resist buying a small bunch to take some pictures! In two or three months, we will have the full glory of the “real thing” in the gardens :)

Most of what is visible here appears to be oyster shell material, plus one dark glass fragment/sea-glass-like piece.
Identification
1) Left shell
A single oyster valve, shown interior-side up.
Most likely from an oyster rather than a clam or scallop because it is:
thick, heavy, and irregular rather than symmetrical
strongly layered
broadly elongated instead of fan-shaped
showing the typical rough growth accretions of an oyster shell
Oyster shells consist of two valves, and in many oysters one valve is flatter while the other is more cupped. Their shells are notably variable in shape, depending on where and how they grew.
Visible details in your specimen:
creamy white to tan shell
orange-brown iron-like staining along growth edges
a smooth inner surface with a darker, elongated adductor muscle scar area
obvious laminated shell buildup along the margin
That darker inner scar is consistent with the place where the oyster’s main closing muscle attached.
Oyster interiors often show a pale to purplish muscle-scar area.
2) Center shell
Another oyster valve, this time shown mostly from the outer surface.
This is the roughest and most sculptural piece in the arrangement. It shows:
dark gray to charcoal
weathering
pronounced folded ridges
stacked growth lines
a heavy, thick shell body
That crumpled, irregular relief is typical of oyster shells, which often grow attached to hard surfaces or to one another, causing very uneven shell form.
Oyster shell shape is highly variable and often distorted by crowding, attachment, and substrate.
3) Right shell
A third oyster valve, also interior-side up.
This one appears more bowl-like and worn, with:
pale cream interior
a rounded interior basin near the hinge area
gray-black weathering and attached residue on the margin
chipped edges from wear or breakage
The cupped form fits the general oyster pattern in which one valve is more concave and provides more internal space for the animal.
4) Bottom foreground shell fragment
A long, flattened oyster shell fragment or valve fragment laid horizontally in front.
It looks weathered and thinned, with:
long laminated edge structure
muted tan, cream, and gray bands
a smoothed, beach-worn appearance
remnants of the inner shell surface and darker stained areas
This piece reads as the most abraded shell in the group, probably water-worn longer than the others.
5) Dark rounded fragment at lower right
This is most likely a glass fragment, probably sea glass or a wave-worn shard of thick glass.
I would not call the exact original object with confidence.
Why it looks like glass:
one side is smooth and translucent
the opposite side is distinctly frosted
the edges are rounded rather than sharp
t
he interior shows colored depth that shell or stone would not usually show in this way
Authentic sea glass forms when broken glass is physically abraded and chemically weathered in water, producing rounded edges and a frosted surface. Common colors are clear, brown, and green, while darker or unusual tones can occur depending on source glass.
What the whole arrangement is
This is essentially a still life of marine beach finds:
several oyster shell valves/fragments
one weathered glass fragment
arranged on a warm brown/orange surface that emphasizes the cream, gray, and dark violet-black tones
Visually, the set has strong contrast between:
matte, chalky, layered shell
dense, ridged, sculptural shell relief
smooth/translucent versus frosted glass
warm background against cool gray and off-white subjects
Level of confidence
Oyster shells / oyster shell fragments: high confidence
Specific oyster species: low confidence from image alone
Dark fragment as sea glass / weathered glass: moderate confidence
Exact source of the glass fragment: insufficient information

"Fuchsia Cluster #2" by Patti Deters. Four hanging flowers and buds make for a pretty piece of art. The pinkish red and lavender purple blooms are big, soft, and very attractive in hanging baskets. A slight variation on #1 in this series. Please enjoy more of my (botanic and more!) images at patti-deters.pixels.com.
