    On our Trip to Santa Cruz, CA I tried photographing the ocean waves and a little stream. The Stream photo I did crop it some.

    So you’ve certainly captured some motion here in the image of the stream. Obviously in a slow shutter speed image like this camera shake is a problem.

    What’s important here is to understand that shooting slower shutter speed images is possible but you have to rememember that more light comes in at these slow shutter speeds. So you have to compensate for it.

    Stream photo:
    Date Time Original: 2012:11:25 14:58:45
    Exposure Time: 1/10
    F Number: f / 5.60
    Exposure Program: Manual
    ISO Speed Ratings: 400
    Metering Mode: Pattern
    Flash: Flash did not fire, compulsory flash mode
    Focal Length: 105mm
    White Balance: Auto white balance <- (explains the blueishness of the image)
    Make: NIKON CORPORATION
    Model: NIKON D7000
    LensInfo: 180/10 1050/10 35/10 56/10
    LensModel: 18.0-105.0 mm f/3.5-5.6
    Lens: 18.0-105.0 mm f/3.5-5.6

    You’ll note that your photo of the waves is very blown out. There is just way too much light in this scene to shoot an image with that slow of a shutter speed. You’d have to use a neutral density filter and alter your camera settings accordingly. ISO 640 is way too high for this kind of image.

    Exposure Time: 1/100
    F Number: f / 14
    Exposure Program: Manual
    ISO Speed Ratings: 640 <- (part of the reason it's so blown out)
    Metering Mode: Pattern
    Flash: Flash did not fire, compulsory flash mode
    Focal Length: 62mm
    White Balance: Manual white balance

    Lens: 18.0-105.0 mm f/3.5-5.6

    Here is a histogram for this image. You’ll see how it is clipping.

    That being said I think you understand how to capture motion you just need more practice.

    If possible use a tripod, reduce camera shake, shoot in the right kind of light or use filters accordingly.

    Sound good?

    Thanks! 😀
