Hot weather = Hosepipe rainbows. Simple science and photography combined to make a fun assignment for a scorching day.
Rainbow colours are always the same - and always appear in the same order Red, Orange, Yellow, Green Blue, Indigo, and Violet.
Remember Shoot this on a camera or phone Stand with your back to the sunlight (you should be able to see your shadow on the ground between you and the spray) It works best when the sun is fairly low in the sky If possible shoot towards a dark part of the garden You can ask a sibling or your parents to help. Include them in the picture or just shoot the spray Decide how wide your hospipe spray is. I used it on the middle setting but some people think the fine spray is best It works with a watering can too - but it's tricky Keep the camera/phone dry Take lots of pictures in the sunshine you won't be able to see which ones work so shoot a few extra
Experiment with shutter speed if you have a bridge or Dslr camera. Shot at 1/2500 sec. A very fast shutter speed freezes each droplet and as a happy bonus throws the background out of focus. The 5.6 aperture keeps the cat just recognisable. ISO 250
1/125th Sec - not super slow but just enough to turn each water droplet into a streak of white light whilst avoiding camera shake. The back ground is very sharp however with an aperture of F14. ISO is at 100 for this image and without neutral density filters it is impossible to shoot a slow shutter and wide aperture.
Which image do you prefer ?
This video shows that the rainbow is only visible from one spot. Move around until you find it.
