One common mistake committed by several PowerPoint users while designing presentations is inserting pictures with a background that conflicts with the template’s default background transparency.
Imagine you have a PowerPoint template with a dark background and you wish to insert a stock image or illustration. Most of them include a white background by default. It totally looks weird having an image outlined with white background on a dark background.
Fortunately, PowerPoint 2010 has intuitive background removal tool to crop out the background retaining the fine edges
1. Double click on the picture and select Format -> Picture Tools and then hover to the ‘Remove Background’ tab on the ribbon . The ribbon will feature a series of buttons to refine the selection edge and to exclude the background from the image.
2. Drag the rectangle marquee over to the portion of the image you wish to exclude from. Choose ‘Mark Areas to remove’ button on the ribbon and select every portion of the image you wish to mask.
3. You might accidentally trip over in the above process and select a portion of the image to remove (which you really don’t want to exclude), This is where ‘Mark Areas to keep option comes to action’ Select the portions you’ve accidentally removed
If you are dealing with a large image, this might take up to several minutes as you need to mask out every portion of the image.
4. When you’re satisfied with the result achieved, click on ‘Keep changes’ button from the Ribbon.
I have an older version of PowerPoint, what do I do?
You’ll have no choice but to use a professional photo editing software like Photoshop or GIMP, which includes the handy “Remove Filter” tool, which provides the same functionality.
The same process implies for Excel, Word and Outlook 2010 as well.
