The final product of the nature videographer can be a work of fiction, however this is not usually the case.
Most nature programs purport to represent nature, more or less accurately.
Thus there is a responsibility on the part of the producer of the program to ensure that what is being presented is an accurate and a realistic representation. The first issue is that of accuracy. We strive to ensure that all our narration is scrupulously correct. We check and double check data. We ask friends to check after we have checked.
