took this in black and white with red filter setting in camera, and then realised i had the camera set to RAW so i used the channel mixer again, its actually growing on me as a quick way to get the best from a black and white .
Before setting you this week's Get Pushed challenge I've just checked what the flash of red requirements are for this week - using the same thing to focus on all week. Your challenge works with that, but it's not going to work with my first thought which was panning. How about a challenge when you focus on the shadow of your object, either by using the shadow as part of the composition or even as the main subject?
