In legatura cu cautatul (si din pacate – gasitul) celor care fura fotografii, ignorand legile drepturilor de autor am mai gasit cateva site-uri care functioneaza in felul urmator: in momentul in care se introduce o cautare noua – o fotografie oarecare – acesteia i se va genera un fingerprint unic (o semnatura) si o va compara cu cele deja colectionate in baza de date.
Fata de solutia care cauta dupa date din EXIF (prezentata in post-ul anterior) aceasta are sanse de reusita mai mari. Datele din EXIF de puteau ajuta macar sa localizezi camera, daca se urcau neprocesate pe internet, dar cum toata lumea photoshopeaza…
Canon has released a firmware update for the Canon EOS 7D digital SLR camera. Version 1.2.5 improves read and write speeds when using UDMA 7-compatible CF cards, and addresses various issues with custom function C.Fn 4-1, movie and still capture using certain CF cards, and menu screens displayed in Arabic and Portuguese.
Nikon has issued a firmware update for the Nikon D7000 DSLR camera. Version 1.02 resolves a number of issues and changes the way long-exposure noise reduction is performed. Specifically, dark frame subtraction is now applied to all photos taken using shutter speeds slower than 1s. Previously, long-exposure NR was applied to photos captured with exposure times longer than 8s only.
Version 1.2 adds a new menu item, “Picture Orientation”. Given that the camera’s orientation sensor might not always be able to correctly recognise if an image was taken in portrait or landscape orientation, users will now have the ability to specify the orientation of any given image in Playback mode simply by a turn of the click-stop dial. The user-defined picture orientation is then saved in the EXIF.
Every photo you take with your digital camera contains hidden information about both the image and the camera such as the make, model and date. This information, called exif data, can also include a unique serial number which identifies your camera. stolencamerafinder crawls the internet searching for photos, collecting the serial numbers of the cameras that took them. When you use the drag & drop feature, stolencamerafinder reads the unique serial number from the exif data of your photo and uses it to match against serial numbers it has stored.
Asta, cu siguranta functioneaza, pana in momentul in care cel care urca pe internet fotografia facuta cu camera instrainata (sau urca in alta parte o fotografie furata) va trece fotografia prin un soft de editare iar serial number-ul camerei va disparea din exif…
Pentru ca pe multi ii streseaza ideea ca entry level DSLR-urile sunt fragile, iar carcasele de plastic… nu sunt la fel de rezistente ca cele din aliaj de magneziu… cineva a avut timp sa testeze cat de rezistente sunt DSLR-urile “de incepatori”. Dureaza cam mult filmuletul – “do not try this at home” dar rezultatele sunt WOW. :)) MWHAHAHA!
People always question how tough the more basic level DSLRs are and treat them like delicate objects. But are they really tough enough to take the abuse that one might give it during daily life? Does a magnesium alloy body mean everything when it comes to “tough bodies”? We take these two DSLRs and put them through some extreme tests that you might possibly be able to relate to during your daily lives. Watch the video to see if they survive these rigorous tests.
*As it turned out, the budget of this video was limited, so a 400D was used and Kai’s own Nikon D70. (*.digitalrev.com)
