Nature Effects: Water

This effect can be used to add a body of water to an image.

Before you adjust the parameters for this effect, use the Move tool to set the height of the expected horizon.

Set the horizon line

Below the horizon will be water, and above it, the remainder of the image. The horizon can be moved vertically up or down to any level.

Adjust the parameters for the Water effect. The parameters for this effect are divided in two tabs: Waves and Glare.

 

Waves Tab. Under this tab are parameters which define the basic characteristics of water.

  • Density (0-20). This parameter determines the number of waves per unit area at their regular size. The higher the value, the closer the waves will be to each other and and the number of them will increase.

    \"Density
    Density = 5
    \"Density
    Density = 15
  • Height (1-100). This parameter determines the size of a wave in the vertical direction. The higher the value the higher the wave.

    \"Wave
    Height = 20
    \"Wave
    Height = 40
  • Length (1-100). This parameter determines the size of a wave in the horizontal direction. The higher the value, the longer the wave.

    \"Wave
    Length = 40
    \"Wave
    Length = 70
  • Direction (0-180). This parameter determines the direction of the flow of waves. At a value of 0, the waves are perpendicular to the flow of water. As the value increases, the waves will move clockwise.

    \"Direction
    Direction = 60
    \"Direction
    Direction = 120
  • Dispersal (0-90). This parameter determines the difference between the direction of waves. When the value is set to 0, all waves follow the same direction. As the value increases, individual waves deviate from the direction specified by Direction. The higher the value, the greater the deviation.

    \"Dispersal
    Dispersal = 20
    \"Dispersal
    Dispersal = 80
  • Depth (0-100). By adjusting this parameter you can change the visual perception of the water\'s depth. The higher the value, the darker the water and the greater its depth.

    \"Depth
    Depth = 20
    \"Depth
    Depth = 60
  • Ripples (0-100). This parameter adds an additional relief effect to the waves and determines the degree to the effect. The higher the value, the more ribbed and embossed the waves will be.

    \"Ripples
    Ripples = 0
    \"Ripples
    Ripples = 30
  • Color. Use this parameter to change the the water\'s color and select the appropriate color based on the type of body of water. To change the color, click on the color plate and choose a color from the Select Color dialog.

Glare Tab. If the original photo has a light source, then when you add water light should be reflected in it, creating a glare. The parameters under this tab define the characteristics of the solar glare.

  • Brightness (0-99). This parameter defines the brightness of a solar glare. The higher the value, the brighter the glare on the water.

      Note: If the value of the parameter is 0, there is no glare.

    \"Brightness
    Brightness = 50
    \"Brightness
    Brightness = 90
  •  

    These parameters affect the location of the glare on the water:

  • Horizontal Shift (0-180). This parameter controls the horizontal position of the glare. If the value is set to 90, the sun is above the center. At values greater than 90 it is located to the right, and at values less than 90 percent, to the left.

    \"Horizontal
    Horizontal Shift = 70
    \"Horizontal
    Horizontal Shift = 110
  • Vertical Shift (0-90). This parameter controls the vertical position of the glare. The higher the value, the more distant the glare will be on the horizon, and the higher its position will be relatively to the camera.

    \"Vertical
    Vertical Shift = 75
    \"Vertical
    Vertical Shift = 85

      Note: These parameters only have an effect if Brightness for a glare is not set to zero.

      If you wish to add a glare, pay attention to the lighting as well as the time of day in the photograph. As we know, the sun is lower in the sky during the morning and evening than during the day.

      Therefore, for photographs taken during the day, the glare should be closer to the camera (a lower value for Vertical Shift), and for one shot in the morning or evening, closer to the horizon (a higher value for Vertical Shift).
      Similarly, the value for Horizontal Shift can be changed, depending on the position of the light source in the original photograph.

  • Color. This parameter determines the color the solar glare. To change the color, click on the color plate and choose a color from the Select Color dialog.
