I have mentioned before about the interesting images you can get if you use movement. There are two sorts of movement; Camera movement and Subject movement. With Subject movement you have to make the decision whether to stop movement or to show movement.
Last weekend I was in Shropshire’s Cardingmill Valley and the light, (not sunny), was just right for some “show movement” images. There’s a delightful stream running through the valley with some small cascades. It’s not a huge stream, just a few feet across.
For this 6-inch drop I used a wide-angle lens low down to give an illusion of larger size. I used a 1/15th of a second to show the movement in the water, whilst keeping the camera as still as possible. This shutter speed shows enough movement but keeps the structure of the water visible. It’s not just a misty vagueness. The main problem here was lots of water droplets splashing on to the lens filter!
I moved upstream and found water spilling over the weir of a small reservoir. The water was moving down so during the exposure I moved the camera up, in the opposite direction to the water flow. With a 0.5 second shutter speed the blur of the moving water has been added to the blur of the moving camera.
In this last image I’ve used the same moving camera technique but kept it still for part of the 0.4 second exposure. You do need to practice this quite a bit to get it right, but it’s worth it. There’s now a blurry image from the camera movement, a blurry image from the water movement, and a sharp image from the static camera part of the exposure. It’s all done in-camera, with just some contrast control work in Photoshop.
