PS through the calculation of the selection of clear glass carved ice carving pull Map

When executing the "Apply image" and "compute" commands, we tend to mix two channels, not knowing that PS also allows the selection to be used as a channel, but more often than not, we think the hybrid channel

It's just a matter of two channels, so it ignores the existence of a constituency. If you can make the most of the existing selections in the image, you may find more solutions for selecting the image. In this case,

We use the mixed results of the selection and the channel when we choose the ice sculpture.

Steps: Compare Channel---Draw ice sculptures in channels---make ice sculpture selections--for ice sculpture coloring--to replace the background with the "calculation" command.

1. Open the file. The surface of the ice sculpture is very smooth, and the shape is not complex, suitable for using the pen tool to draw the outline, as for the transparent area of ice sculpture, you can find a solution in the channel.

2. In the color image, the ice sculpture and the background in both color and texture are very close, we still first look at the next channel is a clear outline. View the red, green, and blue channels in the channel respectively.

It is found that the contour of the ice sculpture in the green channel is the most obvious.

3. Click the green Channel in the channel palette to display a grayscale image of the channel in the image window. Draw the outline of the ice sculpture with the pen tool. Click to load the path as a selection button in the Path palette.

Load the made selection.

4. Executes the calculation command, opens the Calculation dialog box, sets the channel for source 1 to selection, the channel for source 2 is red, and the blending mode is set to multiply.

The result is "new channel." Click the OK button to create the mixed result as a new channel.

Tip: The ice sculpture in the red channel is the most detailed, so in the "calculation" command, we use the red channel and the selection to compute, and the selection limits the calculation to the ice sculpture,

In this case, the outside of the ice sculpture will not participate in the calculation of the background, PS will be filled with the black without the calculation of the area, the background becomes black. The "multiply" mode darkens the image in the channel,

After the ice sculpture is selected, the influence of the background image on the ice sculpture becomes smaller.

5. Press the ctrl+~ shortcut key to return to the color image state. Alt-click the background layer to convert it to a normal layer. Click the Add Layer Mask button to mask the background.

6. Creates a new layer, fills the blue in the layer, sets the layer's blending mode to color, and the color mode applies the current layer's hue and saturation to the ice sculpture image below,

But the ice sculpture image brightness remains unchanged, so that it can be colored ice sculpture, Blue will highlight the crystal texture of ice sculpture.

7. We can also add other backgrounds to the ice sculpture.
