If you see that some images are unlikely to reveal your background story, text descriptions will help you a lot.
Don’t start writing your essay from the text parts.
Thus, you have to write your descriptions and notes according to the message of each particular illustration.
For example, if some image is funny, you have to point out what is funny about it, in the text.
Check all prompts and talk to your instructor if necessary.
Familiarize yourself with criteria of your work, and think how you can get good images related to your topic.
You have to pay special attention to the background of your photo shoot, since pictures will be the crucial part of your essay. After you clarified all necessary details of the photo shoot, think of your audience. Make sure that the information will easily reach your target audience.
For example, if your essay is oriented towards children, you have to add more things that reflect their interests; you may also include some elements of play and use bright colors.
Usually, a written text just describes details that can’t be seen in pictures.
At the same time, images remain the main writer’s tool.
