In the days of 35 mm film it was adequate in evidence to produce a print that was endorsed on the back with words similar to "this is a print of a photograph taken by (me) on (date and time) at (location) and is a true record of my observations at the time. In an official capacity the veracity of those photographs has never been challenged.
No photographic evidence stands as sufficient proof on its own - it is important to make clear and legible notes of what each photograph is showing.
In a private capacity I have found that if the tenant is present you can point out to him or her each of the photographs you are taking and what they are showing.
If your photographs tie in with the notes made at the time and those notes are countersigned by the tenant that is further evidence.
Are we going down a false track of looking at the photographs as absolute "proof" rather than as additional evidence to substantiate written notes and documents?
The judge will consider the quality of evidence from both sides before arriving at a decision.
To save costs I have sent copies on CD of photographs showing the condition of the property on a tenant leaving and subsequently endorsed prints from those photographs have been accepted by the Court and (so far) have not been disputed by the tenant.

Without Plain English Codes of Practice and easy to complete Prescribed Forms the current law is too complex and is thus neither fair to good tenants nor good landlords.
