Schneier - Lifting a Fingerprint from a Photo
Police in the UK were able to read a fingerprint from a photo of a hand:
Staff from the unit's specialist imaging team were able to enhance a picture of a hand holding a number of tablets, which was taken from a mobile phone, before fingerprint experts were able to positively identify that the hand was that of Elliott Morris.

Speaking about the pioneering techniques used in the case, Dave Thomas, forensic operations manager at the Scientific Support Unit, added: "Specialist staff within the JSIU fully utilised their expert image-enhancing skills which enabled them to provide something that the unit's fingerprint identification experts could work. Despite being provided with only a very small section of the fingerprint which was visible in the photograph, the team were able to successfully identify the individual."
