Using PowerPoint to manipulate images: Creating soft edges

This is the second tutorial in a series on ‘Using PowerPoint to manipulate images’. For people like me that doesn’t own nor has the graphical skills to use the high end graphics packages, PowerPoint is my primary image editing tool, even if the end location of the image is going to be somewhere else (Word, Excel, VLE etc.)

A lot of people when adding images to resources will find an image, and chuck it in without thinking about how the image looks, what size it is, what other images are visible alongside it etc. If I am using an image as a ‘decorative’ element designed to break up the text and to act as a ‘memory hook’ for the learner, then one technique that I sometimes use is to change the image to have soft edges. This (as the name suggests) softens its appearance, so it blends into the ‘page’ rather than having the harsh sharp edge that makes it stand out. If someone is going to be spending a lot of time viewing a particular screen, having soft edges can be easier on the eye than the harsh edge of a bordered image.

Here is an example of an image that I have used in a PowerPoint presentation:


Image of 2 carnival goes wearing skeleton masks and hats. The image is rectangular with a hard border.

Here is the same image that has been turned into an oval and had the edges softened (annoyingly the theme that I use for this blog, puts a grey border around the image that I don’t want!):

Image of 2 carnival goes wearing skeleton masks and hats. The image has soft edges and no border.
The following video shows how easy this is to achieve, note – it is possible to edit multiple images at the same time – if you hold a finger on the ctrl key whilst clicking on the images you can multiple select those images, and then any changes that you make is applied to them all consistently.
