Left one looks much more yellowish / warmer than the right one. I think the left one should be white balanced to have a more neutral foreground (and maybe the right one too - hard to judge on a phone screen), and then let's see the difference Link to comment Share on other sites More sharing options...

They don't state the white balance setting on the left shot as far as I can see. The info maybe somewhere else, I did not look it up. To be honest, the colors in both shots don't look really that pleasing to me. The left one ist way off in colors in my opinion. The right one I would personally have tried to achieve a warmer color on the foreground and less magenta. You can get those more greenish water colors in tropical waters if you shoot really shallow at sunset. But that particular picture does look a bit too much green even for such a shot.

John E Posted June 2 Share Posted June 2 Thanks for the comparison photos, and for shining some light on this topic. Some replies have been illuminating. They do show the importance of smooth light fall off especially when using dual strobes angled slightly outwards to get even light across the picture Personally, I think the very colour-saturated coral reef photos, whilst beautiful, are quite unoriginal now and get too much exposure, whilst ambient light pictures that more closely reflect what we really see under water (and preferably capture some of the magic of it) are mostly left in the dark. Before I warm too much to making bad puns I will cool off and go and recharge. 1 Link to comment Share on other sites More sharing options...

I did’t know that rule. The video showed the left image of the bs promo pic screenshotted and taken in Adobe Lightroom. Then simply moving the white balance slider to the left until reaching approx 4500K. The result was the image presented on the right 😎 by bs to promote their diffusor.

In quote I put together non-diffused S220 (first) and Apollo (second) and they seem very similar to me... I might even prefer S220 to Apollo... The fly built in diffuser of Inon is brilliant I think.

RomiK, the two photos you have in your quote are both the Apollo (with and without diffuser). That's why they look the same. Link to comment Share on other sites More sharing options...

DreiFish Posted June 10 Author Share Posted June 10 (edited) First, Marelux Apollo 3s at full power, with diffuser I judged good exposure to be ISO 100 F16. Second, the Inon S-220s at full power, with the 4600k filter Best exposure was at ISO 100 F11. The Inon S-220 picture was probably a few inches closer with slightly different framing (you can see from how much of the wreck was captured) I'd say that basically power is 1 stop lower, but the big difference is that the S-220 has less wide coverage and much more of a hotspot. Also, please keep in mind that 2 strobes are used in each picture, at 10 and 2 o'clock. So this is the exposure you'd get with 2 strobes, not just one.
