Rob Trek covers a lot on flash photography, which is a black art in itself. You notice these so-called visionaries and ambassadors don't talk much about flash photography, because they suck at it.Thanks. I am now subscribed to Rob Trek.
Ha ha... Yes Robin Wong do articulate a lot. But nowadays, there are so many Youtube channels I subscribed to. I usually like them play in the background while doing some work. Only when what they say is interesting or have something to show, then I put it in the foreground to watch a while. As there is no point looking at a speaker speaking unless they have something to illustrate.
