How To Make A Light Switch Powerpoint Light Bulb Animation
A lightbox is an effect often used on websites. Yous click something and you lot see a window, but everything effectually the window is faded every bit if it's covered with a semi-transparent overlay. This effect focuses your attention on the window.
A mask is slightly unlike and you sometimes see it in video. Everything is completely covered except for 1 area. You can see whatever is backside that area. Essentially, that surface area or shape is a pigsty in an opaque shape. Once more, this focuses your attention on what'south behind the hole — since yous can't see annihilation else.
And so both of these techniques help focus attention on office of a screen. In PowerPoint, you can use these techniques to focus attention on part of a slide.
There are other techniques that you tin apply. For example, look at this blog post, "Circle an object," which explains how to focus attention by circling an object.
This video shows both techniques, i after the other.
Example 1: Lightbox effect (everything else is semi-transparent)
A lightbox typically has a zoom animation with information technology, although you could likewise apply a simple Appear or Fade animation. Hither are the steps for creating this effect:
- Draw a rectangle across the unabridged slide. (In this instance I drew the rectangle beyond the content surface area of the slide and didn't comprehend the light-green-bluish border.)
- Right-click and cull Format Film. In the Make full expanse, set the rectangle to about l% transparency. Set the color, too. I chose a medium grey, but yous could employ white.
- In the Line area, choose No Line.
- Draw an oval (or any shape) over the expanse you desire to emphasize. As you did with the rectangle, make it semi-transparent if you need to see exactly what to cover. Then move and resize it so it covers the right expanse of the slide.
- Select the rectangle, so press Shift and select the oval. On the Format tab, cull Merge Shapes, Decrease. I explicate that feature in more detail here. (Note that the feature is available in PowerPoint 2010 and afterward and is non easy to detect in PowerPoint 2010; run into the blog mail for a link to more data about that.) For PowerPoint 2007, you can employ the Set Transparent Color feature. I explain in an older tips on masks called Create Cutouts.
- With your lightbox selected, click the Animations tab and choose the animation yous desire. For example, click the Add Animations button and choose Zoom from the Archway animations. If y'all don't see information technology, click More Entrance Animations at the lesser of the list. (In 2007, cull Animations tab> Custom Animation and then choose Add Outcome.) You might desire to change the timing to make information technology slower. I found 0.75 seconds to be nearly right.
Example two: Full mask (everything else is opaque)
This technique is the aforementioned except that the large rectangle is opaque. Just make information technology semi-transparent while you're adding the smaller shape so you lot can see where to put that smaller shape. After subtracting, make the resulting mask opaque again. In this case, I used a trapezoid instead of an oval because it pointed out the focus area better and I used a Wipe (from left) animation.
Can y'all remember of other variations that would look amend? How would yous employ these techniques? Leave a comment! And please share with your colleagues using the Share buttons below.
