UCalgary photographs with the spark already added in are available on the UCalgary photography DAM. (Use search term "Creative Assets" to filter images. Alternatively, find the "Creative Assets" folder in the left menu. It is the first folder nested under the "UCalgary Photos" folder.)
For images where there isn't space for the large spark to be included, the colour of the image needs to stay at full saturation, or for portraits, the spark can sit as a small icon on top of the image. The image's original colour does not need to be altered. A light or dark gradient may be added to help the spark stand out from the image.
