Everyone! So I've covered slow shutter speeds, sunbursts and black backgrounds. What other Creative Underwater Photo techniques should I cover next?

Very nice video. Many thanks for sharing- Hugs:)) ~Sara~

Thanks Luca! This effect is really popular these days, so hopefully this inspires us all to try the technique.

Great video, and great timing too! I’ve been trying this technique out the last few dives, but I’m having issues with getting the subject in focus; everything’s blurred, even though I’m illuminating with two strobes and super close to the subject. That being said, I am using rear curtain flash even for circular motion blur. Do I just need to up the strobe power, or does it work more effectively with using front curtain flash?

Hi George, the timing is indeed perfect. Front and rear curtain sync won't make a difference in terms of strobe power (sharp subject). Rear curtain sync is nice for slow shutter speeds because the blur happens before the flash, meaning the blur streaks will appear behind the subject, indicating forward movement. If the flash is triggered on the first shutter curtain, then the streaks will appear in front of the subject, making it feel unnatural - like the subject is moving backwards. So, yes, you need to work on increasing the strobe power in order to freeze the subject and create a crisper image. Note that if the exposure becomes too bright, you'll need to stop down your aperture to reduce the overall exposure.

Very nice video as always! I'm trying to get some motion blurr on topside photos (my moving subject is the cat) before than transferring it to underwater since I shoot more uwmacros than big animals.. and I'm feeling that's not so easy to obtain a good looking photo (at least for my taste) even topside. It is surely a matter of practice and speeds, rearsinc helps but still maybe some thing is missing to me... What kind of autofocus do you prefer when shooting? Continuous tracking? Is there a way good way to add motion blurr to macros?

Hi Enrico - Great idea to practice the technique at home before going diving. In short, there's no additional secret, just finding the right situations where a motion blur will look nice. Yes, I do prefer continuous tracking for movement. I also use back-button focus (tutorials.brentdurand.com/back-button-focus/). For macro it is all the same concept, but with much smaller movement - just millimeters. Think about a seahorse moving. Or, better still, is for you to pan the camera sideways and then push the shutter. So in effect, you are creating the motion of the macro subject - not the subject. Hope this helps!

Does rear curtain sync work with the Canon R7? You're using the R5 right? I've heard that sync types are set on the strobes for canon cameras. Do you have special strobes that allow you to use rear curtain sync with your R5? I just ordered an R7 to be used with Ikelite DS160 II strobes with TTL. Do you know if this will allow for rear curtain sync?

Hi Will - If the R7 is like the R5, then rear curtain sync will only work with Canon speedlights, or a TTL converter that communicates with the Canon software. I'm not sure if the Ikelite DS160 II with TTL converter do this or not. Best to ask them. Sorry I can't help more!

Thanks a lot! Does the same apply for video? Thanks

Hi Bernhard, for video the universal recommendation is for shutter speed to double your frame rate. Deviating from this rule is really only used by pros for very special effects (e.g. tense war scene in a movie). For slow motion video you would use a high frame rate and slow the footage down in post-production, although some cameras (e.g. smartphones) feature a slow motion mode that automatically slows the footage down. Hope that answers your question!
