Because the image of the photo is formed by the contact between the light and the film, each photo has a certain degree of authenticity. However, the photos taken from different angles always reflect the truth of one side of the object rather than the whole truth. in this sense, the photos are not true. Therefore, under the current technical conditions, it is not appropriate to use photographs as evidence, especially in court.
The statement 'Any evidence only needs to reflect one side of the fact' most weakens the above argument.
