Even though there are a number of image editing programs you can use to work with individual images, I have come to realise that creating and using overlays can in some instances be more efficient.
I designed and created this series of overlays in PowerPoint which can be effectively used with any slide that has a background image.
The overlay comprises a white border at the bottom of the screen, plus a shadow that appears to separate the background image from the white border. This was easily created using three shapes.
- The key shape is the 97% transparent rectangle which allows the background image to show through.
- The white border is simply a white rectangle shape.
- The shadow is created using a black moon shape, with 70% transparency and 10 point soft edges. This is the shape that needs the most attention.
Once I created the moon shape, I needed to turn this shape into an image (I cut, then paste back into the slide using the paste as picture option), then crop the shape.
I then aligned these three shapes and saved these as an image.
This image can then be inserted into any slide that has a background image, then re-sized to any dimension to suit your project.
Feel free to download the PowerPoint file with all of the elements you will need to use this series of overlays.
