On a visit to Marwell Zoo, I noticed a fairly high powered water jet/fountain which in the available light had a stunning rainbow effect shining through it and decided that this would make a good subject for my next exercise.
Photos with varying shutter speeds
This shot freezes the jet of water from the fountain and all other detail around.
Shutter speed is still fast enough to capture the jet and spray from the fountain.
Shutter speed is still fast enough to capture the jet and spray from the fountain, however the base is becoming blurred and ISO has changed to keep the photo at a constant exposure.
Shutter speed is still fast enough to capture the spray from the fountain but here you can begin to see the base of the jet is blurred.
f/5.6-1/1600-400-194mm
Shutter speed is now beginning to show signs of movement through the entire stream of the water fountain.
f/5.6-1/640-100-194mm
The water jet is becoming more blurred as the voracity of the water fountain becomes too fast for the slower to capture.
f/6.3-1/400-100-194mm
Note a change in aperture to keep exposure a constant.
f/9.0-1/200-100-194mm
Note a change in aperture to keep exposure a constant.
f/13-1/100-100-194mm
The jet of water is now beginning to become streamlined, adding to the appearance of fast moving water/spray. Note a change in aperture to keep exposure a constant.
f/20-1/50-100-194mm
Note a change in aperture to keep exposure a constant.
f/32-1/25-100-194mm
The fountain now appears as streams/jets of water, more appealing to the eye.
Note a change in aperture to keep exposure a constant.
f/32-1/10-100-194mm
The fountain now appears as streams/jets of water.
Due to the light, constant exposure was now getting tricky, stopping down the camera internal exposure setting was one method I used here to try and keep exposure constant.
Note the water droplets from the top of the fountain falling around the base are now becoming blurred.
f/32-1/4-100-194mm
The fountain now appears as streams/jets of water and the water droplets are blending into one.
I used an ND4 filter here to try and lengthen the exposure time/shutter speed while keeping the exposure 'near' constant!
f/32-0.5-100-194mm
The fountain now appears as streams/jets of water and the water droplets become a blur of movement.
I used an ND4 filter here to try and lengthen the exposure time/shutter speed while keeping the exposure 'near' constant!
Altering the shutter speeds, on moving object can help in portraying movement. Personal preference will vary depending if you like to see the fountains water captured still, or flowing as a stream or jet of water. On reflection increasing the shutter speeds can lead to over exposed photos (see 0.5sec - last one) so choosing the correct lighting environment is critical.
