Bearings stuck by magic magnetism.

I inherited this magnet along with the contents of several grandfathers’ workshops. It must be older than I am. I think it's not wearing as well though, except, perhaps first thing in the morning when we’re about equal ;) . I loved the textures and colours of the peeling paint.

I rotated the image to provide a bit more visual interest, an excuse to smile, and to remind us of magnetism’s gravity-defying antics.

A happy accident in some early trial shots showed that this lens can make rather pretty stars if the light is right and the aperture really small so I went back and took some more...

This image is for the week’s Macro Monday group theme Stick. The magnet and bearings together measure just over two inches so we are within the group’s guideline even including the space on the right. Yey!

Thanks for taking time to look. I hope you enjoy the image. Happy Macro Monday! :)

In LR altered colour temperature for a more blue cast to contrast with the red paint; rotated, flipped and cropped to size with a wide format. Vibrance and clarity raised to bring out the paint textures; a bit of playing with the individual colour ranges to add interest. Topaz Detail for most of the sharpening. In Photo a bit of clarity and Unsharp Mask, sharpening the magnet and the bearings but not the stars, using a layer mask.]

Woodland path.

Two or three times a week I go for a walk in one of the local woods. These are open deciduous woodland tracts that adorn the steeper slopes of the valleys around here. Mainly of beech, they are full of plant and birdlife as well as the homes of badger, fox and deer.

I usually take my camera as it's part of my relax-time. But I have discovered that it is amazingly difficult to take interesting images of woods that reflect their peace and calm. Generally you just get an amorphous mass of green and trunks which just ends up being a restless and unsatisfying visual experience.

It's no better with intentional camera movement: just green and brown stripes with wiggles.

One ICM type does hold more promise though, and this is where you have some sort of path to create a story for the eye to follow and then imagine.

This is one of those.

I'm a bit non-existent on Flickr just now which is rather a regret on my part. Hopefully real life will get a bit easier in a month or two and I'll be able to interact more with my friends here. Meanwhile I'll send you all a wave :)

Thank you for taking the time to look. I hope you enjoy the image :)

Iranian artillery shell.

For a while as a child I lived in Abadan, a city in Southwest Iran on Shatt al-Arab river which is the border with Iraq.

If you went to the bazaar in downtown Abadan you’d find local artisans plying their trades: carpets, painting (the paintings on ivory were exquisite) and metalworking. The metal workers would sit in the streets tapping away, engraving and embossing metal objects, both decorative and practical for sale to anyone who might buy - there weren’t tourists as such but there were Europeans living there working with the oil companies with the interest and the money.

It was a good time to be there as a child. In winter my brother and I would paddle across the Shatt in a rowboat from the sailing club and adventure over to the Iraq side. In the summer the sand sharks came up river so we couldn't mess about the same way.

Iranians are ethnically Persian and by nature are a hospitable, gentle, cultured and refined people and it’s hard to realise that this border subsequently was the same one where 1.5 million soldiers were to die in war a few decades later, as militants of the two opposing Islamic factions in the world once again contested for geographic supremacy in the area.

But my narrative is drifting as it is wont to do…

This is a shell case bought by my parents in the Abadan bazaar. It’s been made into a metal box and you can see some of the intricate (though not terribly refined) tooling below. The shell case is two and a half inches wide. The bokeh backdrop behind it is created by a much large heavy brass tray about two feet wide (just used for the colour here).

Much of the metal used by the Iranian metalworkers was recovered from scrap. Old artillery shells could be reworked or melted down and so were prized. You can see that this one has been fired - in the central depression you can see two pits formed by the firing hammer of the artillery piece hitting the central percussion cap. Brass is used in shell cases because when heated by the explosive it readily expands to seal the firing tube.

This is for the Macro Mondays theme today of Copper. Brass is an alloy of copper.

I chose this because of the lovely colours of the patina and circles in the machining of the brass end-cap. The colour comes partly from the colour of the metal salts of the tarnish, but also from the iridescence due to the refraction of light in the thin tarnish coating. So, an iridescent shell just like mother of pearl :)

I have to credit Ali de Niese for triggering the idea - her image today includes a shell case as a base, and it reminded me of this object. The big difference, of course, is that Ali’s has been cleaned attentively whereas this one has been totally neglected for a long time now, lol. But we do have the patina to enoy!

Thanks for taking the time to look. I hope you enjoy the image with its colours. Happy Macro Mondays :)

Torsion pendulum.

When my father wasn’t drinking home-brewed beer or gardening (the two activities seemed to occur together), his main pastimes in retirement were the study of insects - mainly flies (Diptera) and beetles (Coleoptera) - and repairing clocks (which appealed, I guess, to the restless engineer within).

Well more accurately, attempting to repair clocks.

This is the picture of one of my father’s working clocks: a 400-day torsion pendulum chronometer. These clocks just need winding once a year, and rather than having a swinging pendulum the escapement is driven by the twisting back and forth of a weighted disc suspended by a thin strip of steel, in this case about five inches long.

Each swing, or tick, takes about six seconds, and so a minute has five tick-tocks. Because the movement is so slow the energy needed to keep it going is low, and the same sort of coiled spring that drives a weekly-wound pendulum clock will drive the torsion pendulum version for a whole year.

These clock movements are lovely to look at working: quite relaxing and mesmeric...

My own interests take after my father’s in many ways: gardening (wine rather than beer) and insects - particularly ants (which along with the other social insects, wasps and bees, form the Hymenoptera group) - ... and, yes, clocks.

So part of my challenge for the Macro Mondays group’s theme Timepieces this week was to get this clock working. The torsion spring had snapped a while back, and so it needed to be replaced. And these clocks are a pain to set up so they keep going…

But we got there and I was rather pleased with myself even before I tried taking a photo of it. And that is a Good Thing because my normal MM photography experience is a slow descent into desperation :)

I wanted to convey the twisting of the pendulum in the image. I tried a slow shutter speed - about half a second was needed to get the impression of movement - but the blur rather hid what the image was about.

Plan B was multiple-exposure.

This is an in-camera multiple exposure of just three images. At the bottom on the brass disc there are two counterweights on long screw threads which are used to adjust the speed of the escapement so if you - in the image you can count six (on a good day with one eye shut :) ).

The image is cropped to under three inches wide for the group.

Thank you for taking the time to look. I hope you enjoy the image! Happy Macro Mondays :)

Iris.

I love irises. They are such stately and varied flowers. I often think that God must have had his full paintbox open when he created these.

Sadly this one is not in my garden but in one I visited in May last year.

And this image is one by the gorgeous 50mm prime with all its lush blurriness...

For the Friday Flora (Freitagsblümchen) group.

Thank you for taking the time to look. I hope you enjoy the pwerty flower :) Happy Friday!

(Lest you wonder, I routinely change the EXIF dates to force Flickr to sort my images in the right order - I don't do that for groups that need a fresh image from the week. If I do change it, I normally mention the capture date in the description)

[Developed in Capture One using multiple layers to take out the background, and a slight bit of selective colour tuning.
Sharpened with Unsharp Mask in Affinity Photo.
Removed a pollen beetle and some cobwebs and spots (using the inpainting brush - like the heal tool).
Defringed a cyan fringe and here we are :)]
