Our seventh prompt is about “Long Time Exposure”
The prompt runs from Monday, October 23rd to Sunday, November 5th, 2017
Long time exposure holds a lot of creative possibilities. Especially, when we go beyond the sheer need of having to use long exposure times to get the right amount of light into our cameras.
Of course, this is one way to use long time exposure. And there is nothing wrong with that.
Nightly cityscapes for example can be hauntingly fascinating and show a world that can’t be seen with the naked eye. The interplay of light and shadow, the sometimes unusual direction light comes from, and so also the direction of shadows, and last but not least the differently coloured lights can create captivating results.
25 seconds, f/8, ISO 100
Another example of long-time exposure is photography of fireworks:
2 seconds, f/8, ISO 400
Or - in a more playful manner - seeking for possibilities to show the motion of moving objects or people…
0.8 seconds, f3.5, ISO 100
… or going even more abstract with moving lights:
10 seconds, f/22, ISO 100
And there is, of course, the milky-white moving water on lake- or sea-sides and not to forget waterfalls. This has become almost a cliché, but shouldn’t keep you from trying it if you have the possibility.
1 second, f/16, ISO 100
And last but not least we want to mention the possibility of making objects or people transparent or even vanish completely if they move during the exposure.
30 seconds, f/8, ISO 400
But there are surely a lot more ways. The creative choices are endless. So this definitely is something to play around with.
What is “long time” when talking about exposure?
And how can we pull that off?
There is no definite answer to what “long” is. Usually, exposure times are only fractions of seconds, but we can already get fascinating results with exposure times longer than - say - half a second.
Most cameras allow us exposure times up to 30 seconds. And for everything longer, we can either use the “bulb-mode”, which will keep the shutter open, as long as we press the shutter button, or we can use special (programmable) remote-controls.
A tripod, a bean-bag, or any other way of “locking the camera down”, is needed to avoid unwanted camera shake.
We only can make long-time exposures, if we restrict the light entering the camera. We can do that by closing the aperture as much as possible to achieve the desired exposure time and brightness. Sometimes we even have to use ND-filters to further reduce light. Of course, we also want to use the lowest ISO setting.
In case you are not comfortable using full manual mode, the time-priority mode (TV, or S-mode) of your camera is your friend.
All examples in this post are (as you can see in the in the specifics for the shots) exposed for maximum 30 seconds.
Like Matt @catharticexperience so perfectly states:
“The key to any type of challenge is one thing: have fun and be creative! These are hints what can work, please play around and do what works best for you!”
And this prompt certainly holds a lot of possibilities to play around and to have fun.
