    Selecting the shutter when shooting moving objects determines whether moving objects appear static, but sharp or blurred, but dynamic.

    However, when a high-speed photography and the use of tricks in Photoshop, we can take advantage of both approaches: a sequence of exposures, showing the trajectory of motion in the scene, coupled with a sharp image in each frame by a short exposure.

    Effect – expressive, but not easy attainable. You to do this quickly enough to make a consistent subject movement while it is moving in the frame. And the faster the object moves, the faster should be removed. Many of the expensive amateur cameras allow you to shoot at a rate of five to six frames per second. This is usually enough. You need to put the camera on a tripod to ensure the stability of the fixed portions of the scene, and then, when the moving object appears in the frame, to include continuous shooting camera shutter button and hold it. It would be nice if this please look at the manual focus, because the object can not be in the active AF point.

    When you transfer image files to your computer, open the sequence in your image editor. You will see each frame open in a separate window, but we have that they are in the individual layers of the same image. The easiest way to do it using the clipboard by copying and pasting out there between the windows of the image, until they come together in a single file. We talk more about layers and that can be obtained by using them in other articles. Similarly align layers one above the other. This can be done simply – you need to make the angles of each of the layers formed in the corner of the window. When this is done, start to remove parts of the upper layers, which do not contain a moving object by using the Eraser tool, or the introduction of a layer mask, masking part of each layer.

    In the end, you get to the point where the background in the lower layer (do not delete it by accident) has a moving subject, and in the upper layer there are several moving objects.

    Ideally, the moving object must clearly describe the trajectory of its motion in the frame. This method is suitable for sports such as snowboarding, skateboarding and parkour associated with jumps and stunts.

    Initial set:

    • DSLR or compact camera with continuous shooting
    • Tripod
    • Adobe Photoshop or another program that allows you to work with layers

    Tips:

    • Burst speed must match the speed of a moving object. In order to convey the effect it is necessary to pick up.
    • Practice until you get the correct framing.
    • Look suitable object that can be moved in the air.
