Sometimes, visuals are a problem. This is particularly in the case of subjects like spirituality and philosophy, or when we have to make films on imaginary events or futuristic themes. In certain other cases, we cannot film a particular scene simply because the event has already taken place and we do not have visuals, or even because it is too dangerous to shoot. How do we deal with such situations?
Historical events provide us with an alternative in the form of stock shots. For example, if we are making a film on village cottage industries and we want to introduce Mahatma Gandhi in the film, we can use stock shots of Mahatma Gandhi with appropriate permissions.
Obviously, it is dangerous to shoot disasters such as a dam collapse or a volcano eruption, or even the effects of disasters, such as an empty village, to convey the impact of such events. But add some sound effects and music and we have a strong video on hand! If we desire to show a scene from the future or one from the past but do not have footage, we may want to use an on-screen commentator at the location to tell us about the event. If it is an event that happens on an annual basis, we could also use video from the previous year's event.
Shots of nature, like the flowing water, the blooming flowers, rustling of leaves, vast sky, the rising or setting sun, or even the shadows created by light, shots that are defocused, etc. can be used to depict abstract themes like spirituality and philosophy. Photographs, drawings, and paintings come in handy when dealing with courtroom sequences. We may even want to re-enact some portions to drive home the point.
