Sunny day outside? Why not try one of our favourite creative photography ideas and make your own rainbow with a spray of water from a garden hose. Using this technique it is very easy to create beautifully colourful abstracts right at home!
Rainbows are one of the most spectacular displays of light in the natural world. Bright sunlight hits drops of water, gets refracted and separated into different colours, creating an arc of red, orange, yellow, green, blue, indigo and violet stripes.
Everyone knows that rainbows occur when you get the perfect mix of sunshine and rainfall. So if it’s sunny outside, all you need is a garden hose to make your own rainbow effect.
As well as being quick and fun, it’s also a fascinating lesson in the behaviour of light, and makes for wonderful abstract images.
How to make a rainbow for colourful abstract photos: steps 1-2
01 Position the hose
First of all, you’ll only be able to see the rainbow fully in direct sunlight, so make sure you try this on a sunny day.
You’ll need to create a good spread of fine water, so attach a nozzle to your hose that can adjust the way the water spurts out, then set it to emit the finest, most mist-like spray possible.
Alternatively, a pressure washer will produce a nice misty spray. For convenience, fix the hose to a tripod or stand that can be easily moved, swivelled and adjusted.
02 Find the rainbow
You may not have noticed, but the sun is always behind you when you see a rainbow, with the centre of the arc directly opposite the source of light.
So stand with your back to the sun, turn on the tap and adjust the hose angle until you see a rainbow appear in the water.
The rainbow will be easier to see- and show up better in the image- if it’s against a dark background, so try to position an area of shade behind the spray of water, such as near a tree or wall.
