Finally, follow through. The worst thing that you can do is receive a grant and then not be able to complete this project. As the project progress, keep the funding agency informed.

Okay, most of us aren't working on projects of such momentous import, but the point is that photography can have a dramatic impact upon the viewer. By showing selective 'before' photographs of the conditions that you are discussing, you can leave a lasting impression upon the funding agency. If you have an event, if you see a problem, if the roof springs a leak, take a picture. When you are preparing a grant, be sure to include full color photos in each copy of the application. You want to ensure that everyone reviewing the application sees your pictures.
