This is the last video I posted on my old blog, and I want to repost it here as it is really handy, not only because the good Benjamin Von Wong shows how he made one of his great pictures, but also 'cause he quickly introduce a very interesting technique which it saved my ass a few times, which is called the Frequency Separation Technique, and even if it's made for fashion photography, especially when it comes to retouch skin, but it can be also used for various situations. For example I just used to clean the sky on one of my pictures I took this weekend in county Donegal.
