Lightroom currently has the possibility to search for missing photos, which is a very important function. Unfortunately this does not warn about the case where some photos are still present, but corrupted. Given the large amount of data stored on most computers, and the long storage time, this corruption is bound to happen sooner or later (such examples show up regularly on forums). The user therefore needs to be warned as early as possible so that corrective action can be taken (e.g. retrieve from backup) before it’s too late.
Proposition: implement an automatic photo integrity check.
One way of implementing this would be to calculate the checksum of photos on import for all file types (I understand this is already done for DNG s). The verification against checksum could be done either during the regular catalogue optimisation, or at the user’s demand in a way similar to the command ‘Library’>’Find Missing Photos’. This could be then saved into a temporary collection for review by the user.
Lightroom, make me feel confident that my photo collection is sound and safe.
