The COOPH photographers are back and this week, they're taking on a photo challenge which means they can only photograph one colour and that chosen colour is red. 

One image can change us.

A picture, a moment can change the way we feel. Change how we see ourselves. Change our understanding and change the rules. Provoke and change history.

MPB puts photo and video kit into more hands, more sustainably. Every month, visual storytellers sell more than 20,000 cameras and lenses to MPB. Choose used and get affordable access to kit that doesn’t cost the earth. Sell the kit you’re not using to MPB. Trade in for the kit you need to create. Buy used, spend less and get more. Buy. Sell. Trade. Create.

If you fancy giving the challenge a go, you can head out in search of red objects such as mailboxes and roses but the COOPH team have taken it one step further by getting out the paint can and changing the colour of objects. They also use red props for portraits, play around with red gels, set fire to red chillis (be careful if you try this), create a still life from various red objects, capture textures and shoot tail lights on cars. 

If it's something that appeals to you, try having a number of "colour themes" on the go at once – it's not something that you have to go out and shoot in a day, but can be built up over weeks or months. The results can be a very powerful set (or sets) of images which look great in triptychs. 

You could also have a go at colour-popping which you can apply to images you've already captured in Photoshop, Elements, or if you're a smartphone photographer, in Snapseed.
