This tutorial is to help you learn how to make a water motion
blur (slow shutter speed) effect on a photo that had a fast shutter
speed. Normally you would need a tripod to make this effect when
taking the picture, but with this technique you can simply add the
motion blur effect later. Ok, once you have your picture open in photoshop:
1. Make a copy of the Background
Layer, so you have two layers with the exact same photo on them
(Layer>Duplicate Layer).
2. On the bottom
layer (with the bottom layer selected) apply a Motion Blur Filter
(Filter>Blur>Motion Blur). Make sure you set the Angle of
the blur to match the angle of the water flow. And set the
distance to somewhere around 31 pixels. Keep in mind that
you won't see the filter effect because there is another duplicate
layer covering it.
3. Then select the top layer, and
add a Reveal All Layer Mask to it (Layer>Add Layer Mask>Reveal All).
4.
Then pick a big soft paintbrush that you can use to draw in the
motion blur.
5. Then (with
the layer mask selected) simply paint brush the color black
anywhere on the photo where you would like the motion blur to be
seen on the water.
For different photos, you will probably have to change the angle of the
blur, and perhaps adjust the intensity of the motion blur. But
with this technique you do not have to be a professional
photographer to create water motion shutter speed effects. |
