We showed our red pictures at ADAPS last night, via Zoom of course. The brief was to provide nominally 10 images, shot within one hour, all containing some red. It's an exercise in observation, but also an exercise in getting that shutter button pressed without undue hesitation. Should I or shouldn't I press the shutter release? Just do it and get into the feel of the place. A sense of purpose to a photo shoot makes all the difference. Very therapeutic! So we all contributed around 10 images, some more than that, which is fine because we're doing it for enjoyment, not just to fulfill the rules of some competition.
My choice was Astley Green Colliery (of course, where else?) and this is the red that I found, although somebody did ask if I went with a can of red paint. The very thought....
