Creating Images for Web, Video, and Interactive Use - Adobe Photoshop CC - page 265

Create an alpha channel from the selection.
In your alpha channel, the areas that are black are fully transparent, the areas that are white are
fully opaque, and any areas that are gray will be varying degrees of transparency. This is the stand-
ard way that video editing applications treat alpha channels.
7 Choose File > Save As. When the Save As dialog box appears, navigate to the ps13lessons folder and
type ps1302_work into the File name text field. Select TIFF from the Format drop-down menu.
8 In the Save Options section, make sure that Layers is deselected and Alpha Channels is selected. A
warning stating that this image needs to be saved as a copy appears, which means that your original file
will keep layers intact. Click Save. The TIFF Options dialog box appears.
9 In the TIFF Options dialog box, make sure that None is selected in the Image Compression section and
select the Save Transparency check box If you see a warning about transparency support, click Yes.
Click OK in the TIFF Options window. You have saved a TIFF file with an area that will appear trans-
parent in your video editing application.
10 Close the original Photoshop document by choosing File > Close. If asked whether you would like to
save the changes, choose not to save the file.
Creating animation
In this lesson, you will create an animation using the default animation panel. Photoshop CC has two
modes for animation: the Frame mode and the Video timeline mode. Typically, you would use Frame
mode to create animated gifs for use on the Web. The video timeline mode allows you more control and
export options for video formats. You'll start with the simpler Frame mode first, and then work with the
Video timeline.
Working in Frame mode
Working in the Frame mode of the animation panel is much like creating an animation using a flip topic.
When played, each frame is converted into a final animation. Using the Frame animation panel, you can
build individual frames and then have Photoshop automatically create transitions between the frames for
you. This process is called tweening. For this part of the lesson, you will add a floating hot air balloon to
the image of the lake.
1 Choose File > Browse in Bridge and navigate to the ps13lessons folder. Select the images called
ps1303.psd and ps1304.psd , then right-click (Windows) or Ctrl+click (Mac OS) and select Open from
the context menu. An image of a lake and an image of a red hot air balloon open in separate document
window tabs.
