Water drops on a DVD disc, exposed to sunlight.

The mini-universe of a shampoo bottle.

Plastic jewels on a Christmas decoration.

Drops in a water bottle, reversed lens, with the aperture wide open, and sunshine.

Miniature city of a broken LCD screen.

Bubbles in a hand sanitizer.

An RGB LED...but it's actually B-R-G.

These are also drops in a water bottle.

Tip of a sewing needle.

Broken phone screen.

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.

Jewel bearings...

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.

Beads up-close.

Metal tea filter.

Also not a real macro: just a close-up of a lamp with a telephoto lens.

Broken LCD.

2609 - Russian wristwatch.

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.
