I am thinking about forgoing a strobe and instead using a Sola Video 1200 light on an arm. With the light I do not have to worry about misfiring, flooding (well not as much because it is externally charged), there are no cords, and I can see what the picture is going to look like - easy to adjust settings. I 'have heard' this is the next step for underwater photography - "pros are still using strobes, but it is only a matter of time." I have concerns about scaring critters off with a light that is constantly on. I can't really think of any negatives. Can someone tell me if they have tried this route, and how it worked out for them? Is there a flaw in my thought process? 99% of my photography is done on day dives.
Using a light can add a creative effect to your lighting in your photos, but it hardly replaces a flash. I have not used the Sola lights but I have heard a lot about them and am looking to buy one as a focus light.
When i first started shooting underwater I wanted to go this route as well because it saves money. But after using an Inon video light on my old Panasonic P&S, I can say that it was very frustrating to try and get even light coverage in your pics. A flashgun improves light coverage SO much.
Also, shooting at high shutter speeds and/or small apertures will cut out most ambient light including your dive light. Flash also freezes the image so you don't have to worry about hand shake in low light and you can add creative "motion" to images by using a slow shutter speed with a rear curtain sync.
In fact I don't really see why you would ever go with a video light when the new fiber optic triggered strobes are SO EASY and relatively cheap to use. You just point at your subject and your camera reads the image with a pre-flash that gives you the right exposure
The pros will not be changing to beam lights anytime soon (In fact, I think more pros are actually switching to fibre optic strobes). I mean think about it, why don't land photographers use beam lights instead of flash? If you care at all about the quality of your photos, a strobe is the way to go. Have you looked at the Inon s2000? I currently shoot with dual Inon z240's and can't say enough about how easy and reliable fiber optic TTL is.
