4 Specify the delay:
• Choose a value from the pop-up menu. (The last value used appears at the bottom of the menu.)
• Choose Other, enter a value in the Set Frame Delay dialog box, and click OK. If you selected multiple frames,
specifying a delay value for one frame applies the value to all frames.
Choose a disposal method
The frame disposal method specifies whether to discard the current frame before displaying the next frame. You select
a disposal method for animations that include background transparency to specify whether the current frame will be
visible through the transparent areas of the next frame.
Frame disposal methods
A. Frame with background transparency with Restore To Background option B. Frame with background transparency with Do Not Dispose
option
The Disposal Method icon indicates whether the frame is set to Do Not Dispose or Dispose . (No icon appears
when Disposal Method is set to Automatic.)
1 (Photoshop Extended) Make sure the Animation panel is in frame animation mode.
2 Select a frame or frames for which you want to choose a disposal method.
3 Right-click (Windows) or Control-click (Mac OS) the frame thumbnail to view the Disposal Method context menu.
4 Choose a disposal method:
Automatic Determines a disposal method for the current frame automatically, discarding the current frame if the next
frame contains layer transparency. For most animations, the Automatic option (default) yields the desired results.
Note: To enable Photoshop to preserve frames that include transparency, select the Automatic disposal option when you
are using the Redundant Pixel Removal optimization option.
Do Not Dispose Preserves the current frame as the next frame is added to the display. The current frame (and
preceding frames) may show through transparent areas of the next frame. Use a browser to see an accurate preview of
an animation using the Do Not Dispose option.
Dispose Discards the current frame from the display before the next frame is displayed. Only a single frame is
displayed at any time (and the current frame does not appear through the transparent areas of the next frame).
Specify looping in frame animations
You select a looping option to specify how many times the animation sequence repeats when played.
1 (Photoshop Extended) Make sure the Animation panel is in frame animation mode.
2 Click the Looping Option Selection box at the lower left corner of the Animation panel.
3 Select a looping option: Once, 3 Times, Forever, or Other.
4 If you selected Other, enter a value in the Set Loop Count dialog box, and click OK.
