Hot Shots: When a Laser Cuts Metal, Sparks Fly

A Closer Look at This Image

Wow, this image packs a punch right from the
get-go. Bright, powerful and loud, let’s look at why it works.

Dramatic Light and Colour

The laser is giving off plenty of light, so
there was no need to light it externally. Still, there’s lots going on here. The
lines and circles of light from the sparks contrast nicely, and the white hot
light in the middle, cooling to blue with a warmer deep orange at the edge, is lovely.
Exposing for this light source—and keeping the shadow areas of the image underexposed—makes the whole thing pop with colour.

The cutter being red helps too, continuing and complementing
the warm colours of the sparks.

Carefully Chosen Perspective

Usually, I’d associate coloured bokeh
(blurred lights) with something peaceful like Christmas lights or a city from a
distance. This perception is completely at odds with the photograph’s subject.
Although this looks very peaceful, in actuality the noise would be immense. The blurring of the sparks nearest to the camera helps to convey this sense of speed, motion, and explosive force.

It sounds dramatic, but the act of a
laser slicing through metal is violent. From that controlled violence
though, comes something new. For me, this image conjures up the idea of a galaxy and the
Big Bang; particularly with all the bokeh.

Simple Composition

Sometimes central compositions can
fall flat and lack interest. Here though, the cutter being in the middle worked
perfectly, as the sparks fly around it, creating an effect not unlike a splash
in water: ripples of light radiating towards the edge of the frame.
