ugh....I have to echo B's remarks - if you didn't know what a blackwater dive is, you have no business lecturing him on what his settings should be.
I do. I've dived hundreds of times at night, capturing moving objects. If something is wrong, it is wrong, it doesn't change the right that many people do wrong.
Ok, so show us some pics of open ocean sea horses and jellies. Or lacking those, your other moving objects.
I would use F/8 as the default on my 4/3rds macro shooting, but not on my FF R5, even in daylight.
Objects that move after focusing do not stay in focus in DOF until the moment of shooting.
If the object is moving, f32 won't give you a DOF. The important thing is to shoot as soon as you focus. There is no point in using f20-32 instead of f8-11.
High ISO won't help you freeze the image. 100 iso and 100000 iso freeze images with the same success. High iso only helps to make background images more distinct and you do not have such a purpose in blackwater shooting. TTL always works well at ISO 100.
An image is frozen when the flash light hits the object and therefore the sensor. If the speed of the moving objects is more than the shutter lag, blurry will occur behind the image. The only thing that matters is the shutter speed. There is no reason to do 160 instead of 200. If you can do HSS, you should.
You're conflating the high ISO with the DoF choice, and again seems to reinforce that you do not actually understand this very well.
You did not understand what I wrote.
DoF considerations are about the difficulty in maintaining the distance between the subject and the camera when neither are fixed. Dealing with that is the name of the game with blackwater dives.
Sorry, you still do not understand what I wrote.
High ISO is about making up for the limitations of light weight strobes. Unless he had to lower the exposure of these in post, I don't see an issue with overexposure.
? lightweight strobes? all are min GN20. and even 15 GN for these shots, even more.
As for TTL, I've yet to see an expert recommend its use.
There is a saying among amateurs who want to be seen as an expert.. I hate ttl
I think Barmaglot knows what to do and is right in choosing TTL.
