Editing Picture Transfer Protocol (section)

==Extensions==
A number of protocols have been developed that extend PTP. '''PTP/IP''',<ref>{{Cite journal |title=PTP/IP - a new transport specification for wireless photography  |date=2005 |url=https://ieeexplore.ieee.org/document/1405726 |access-date=2023-12-23 |doi=10.1109/TCE.2005.1405726 |last1=Bigioi |first1=P. |last2=Susanu |first2=G. |last3=Steinberg |first3=E. |last4=Corcoran |first4=P. |journal=IEEE Transactions on Consumer Electronics |volume=51 |pages=240–244 |hdl=10379/295 |s2cid=7419639 |hdl-access=free }}</ref> developed by [[FotoNation]] and first implemented in a round of [[Wi-Fi]] digital cameras by [[Nikon]], [[Canon (company)|Canon]], and [[Eastman Kodak]], allows data transfer over any [[Internet Protocol|IP]]-based network. A [https://www.imaging.org/common/uploaded%20files/pdfs/Standards/Final_PTP_Vendor_Extension_Registry.pdf vendor extension registry for PTP] is maintained by the Society for Imaging Science and Engineering (IS&T).

[[Media Transfer Protocol]] (MTP), developed by [[Microsoft]], allows for transfer over wireless or wired networks based in part on FotoNation's PTP/IP, but also allows users to transfer other media aside from pictures, as well as for tagging objects with extended [[metadata]] (such as title, artist and similar metadata).
