I am kinda new at photos under water. I have a tg4 with a sea and sea strobe and want to be able to take stills and video. I have been taking photos underwater for about 3 years). I am looking at adding a big blue 25000 video light to my set up (i have read the thread stating that bb is over rated but I am not a math expert so some ones explanation kinda makes my eyes roll back). My question is can I get good vids with just one light? I know there will be some trade off but I love the strobe for individual shots and hope to add a video light for my vids. I am on a budget and really can't afford 2 video light and one strobe (and them there is task loading.....) . Any advice is appreciated. Bill
