I finally managed to try the tungsten WB setting matched with a CTO gel during a fishing trip. I red about it some time ago in one of Scott Kelby's book and found more information in http://www.strobist.com/ but never really put it into practice for good. The opportunity came during a very early morning fishing session in the Strait of Gibraltar, south of Spain. I was there with my friend Francisco Martínez in his game boat, chasing the Bonitos (Sarda sarda) with top water plugs. Unfortunately, due to the wind I couldn't use any of the soft umbrellas I had with me, and the light is a bit harsh, but I like the final result, even though, being the first one, it can sure be improved.
