Remember the film The Wizard of Oz?. The movie was in black and white until Dorothy's house crashed to the ground in Oz. Suddenly everything was in vibrant color.
You can achieve this same effect on a photo on your slide. Have it convert from black and white to color right before your eyes. (Actually your photo is really grayscale, not black and white, but that is another article later on this page).
You might not think that it is a big deal about which way a photo faces on a slide. Actually, it really is a big deal. Ideally, the subject of the picture should be facing into the slide, not facing away from it. Of course, there are always exceptions to every rule. For example -- if the purpose of your slide is about exiting, then having the subject of the picture leaving the slide would be appropriate.
Don't forget that pictures can also be flipped vertically as well as horizontally.
Use a stickout photo to have the picture spill out onto the blank part of the slide. This effect can be used on any slide of the slide. For example, a rocket might be taking off right out of your photo on the slide.
In the example shown here the beautiful flower spills out onto the slide and text can be wrapped around it for an interesting effect. There is no end to the possibilities you can create using this effect.
Have you ever received a Power Point slide show that contained gorgeous pictures that you would like to keep for yourself? The answer is probably 'yes'. Well it is a very simple task to extract one or all of the photos from this show to save on your own computer.
Caution - It needs to be noted that photos are copyrighted by the owner. If you plan to use any picture from another person's PowerPoint show, you would need to have permission from the owner to do so. Read more on Photography and Copyright
This might be a familiar scenario. You have inserted a picture onto a slide, took a while to get it formatted with just the right border and resized it to just the perfect size. You are happy with the result. Then Mr. Bigwig decides he wants a different picture used instead. You sigh thinking you spent all that time for nothing.
Well here is the good news. You can easily replace the picture while retaining all the formatting you already did. How cool is that?
