A great way to test your event photo essay skills would be to take photos at a birthday party. Take photos of the person celebrating their birthday, photos of their cake before it gets cut, the presents sitting neatly on the table, and so on. Make sure to take photos of all the important elements. To make it easier, try making a list of the important parts of the event. You wouldn’t want to look at the photos later and realize you don’t have any photos of the birthday girl or boy blowing out the candles!
If you don’t have any birthday parties coming up, you can document an event such as cooking dinner. Take photos of the clean dishes, the table being set, and the food cooking on the stove. Think outside of the box when it comes to the word "event." It doesn't need to be a clear cut obvious event. Driving to the store, while menial to some people, is still an event. With a little bit of brain storming I’m sure you can think of other events to document.
