If you believe the hype on the internet, Tineye has the best search algorithm and Google has the largest database, but I've come to realize that Yandex is far better than both. I've never seen Google suggest a completely different picture (and it be the same girl), and Tineye rarely does it. Yandex is just awesome.I dont know why i didnt saw this post earlier...started a similar one some month ago but anyways
As mentioned before YANDEX is a pure powerhouse for me... the image reverse is very helpfull but i also use it to "chain" reverse image search... for example i have a picture of a given scene... then i see the results... sometimes there are another pictures of that scene which i use again for reverse image search and so on...
findporface.com is also helpfull.. you have to be extremely lucky to find a non famous star but its fast so you should give it a try.
Especially for older scenes iafd.com is also a good option... when you can recognize another girl/male you can use the "Check Scene Pairings"... but not all movies/scenes are listed there so dont give up if its not there
Same goes for data18.com... lets say you know the name of the male... then you can search for him and search in his "content" where pictures of the scenes are listed.. maybe you recognize the scene and its done.
The last tip i have is to also search for other forums like https://www.eurobabeforum.com/... this forum is very helpfull especially for questions regarding DSO etc. because there are some posts from movies with all girls included or hints for the "unidentified" ones
I've never used findporface.com. I'll have to try that.
As for Eurobabeforum, I've been a member for almost 11 years, and I like it, but it's not been a lot of help. The member base is small and if the registration process is still the same as when I joined, it's next to impossible to become a member. It was always better when trying to ID european women however.
