I tried the reversed macro lens way back in 2012 for the first time. Back then, I first photographed things that mostly weren't moving at all or just very little.
Turned out that the world is really interesting when you look at it from a close perspective, even the non-living things. Drops on a DVD disc, bubbles in a water bottle, concrete, electronic components, mechanical instruments... all of that can look very different from normal when you get closer. And a double ratio reversed lens is more than enough for this.
To be honest, I haven't stopped taking macro pictures entirely, especially when it came to colder months of the year when you couldn't find insects and plants alive in nature. Instead, I used artificial objects, which you can photograph anytime at home.
I collected some of the pictures from the last 7-8 years, and hope some of you will be surprised when looking at the details of how some everyday stuff can look from up close.
Drops in a water bottle, reversed lens, with the aperture wide open, and sunshine.
Miniature city of a broken LCD screen.
These are also drops in a water bottle.
Not a real macro: water bottle on direct sunlight, photographed from up-close.
This happens if a drop of water gets into your phone's USB connector and simply dries out. It destroyed (oxidated) some of the connector's pins which were soldered to the phone's mainboard - this is the backside of the connector.
Macro can be very useful for documenting electronic repairs, I often use it when I'm repairing stuff.
Network - bubbles in a soap bottle.
HDD heads on both sides of a disc.
Also drops in a bottle, but with flash... I really don't know how the flower pattern got there - can be the reflection of the manufacturer's logo.
Clockwork (pocket watch).
Fujitsu MBM27C32 EPROM chip. EPROMs are programmable, erasable ROM memories, widely used in the '70s and '80s. They can be erased with UV light, so they have a small glass over the chip itself...
Tip of a needle used in electrical testing equipment. It's only a little broader than a sewing needle's head.
Also not a real macro: just a close-up of a lamp with a telephoto lens.
SMD diodes on a printed circuit board.
This image was taken with a tandem lens (Canon 18-55 and 70-300 together), which produces very high magnification, but it's very hard to use. Even the traces and components on the chip can be seen. The 4 long things are the wires which are connecting the chip to the output pins of the package.
