The return of the bubbles: fourth in the trilogy

Typical! The day a new lens arrives in the post is the day it starts raining. We've had several weeks of superb spring weather, augmented by the total absence of aircraft contrails across the blue sky, but now that I want to get outside in earnest the heavens open.

So I resort, once again, to bubbles. At least they will keep me occupied until the skies clear again, although it won't challenge the lens's capabilities to any degree.

One thing I can confirm with this type of photography (and I think I'm done with this particular subject, now) is: the colour of the washing up liquid I use plays no part in the final outcome of the images (insert winking emoji here).

The weekend promises to have better weather.

Light and gravity

I'm being constantly amazed at what I'm seeing with bubble photography. To light each formation I'm using a diffused flash head above and to the right of my subject to highlight the shapes, but also arbitrarily positioning a small hand-held slave flash with a red gel taped over the tube for each shot.

But what really makes the difference are the myriad patterns and colours created from the same solution at any one time. This is caused by light bouncing around between the inner and outer layers of the very thin bubble wall, each part varying in thickness under gravity. Agitation of the surfaces - by gentle blowing - increases the effect before they burst and are gone forever.

Bubblicious!

Encouraged by yesterday's first attempts at photographing what amounts to soap in a dish, I take a second bite of the cherry this morning to see if I can improve on things.

Dabbling with a technique or practice will never produce consistant results, and at the moment I'm using an impromptu setup thrown together with what I have to hand. The rig is tricky to work with as it stands, and for these reasons I'm doing some research into what I need to take this branch of photography seriously.

I need to stay in more

Looking like threads of silver wire soldered together, bubbles created with a blend of water, washing up liquid and glycerine create unique tabletop subjects.

After mixing 75 ml of water with the detergent at a ratio of 3:1 in an old darkroom measuring graduate, I added a tablespoon of glycerine to the concotion. The solution was then poured into an old lens cap, and air blown into it using a drinking straw; the glycerine being added to keep the bubbles stable long enough to make a composition.

Photographed side-on and lit from overhead by a single flash unit, I moved the light around until I got the look I was after.
