In Topic: Question on strobe power and Syncing with Camera D7100 YS 250 Strobes

19 June 2015 - 01:27 AM

Sounds like time for testing.  First at home in a dark room then at the pool.  You do not want another unsatisfactory trip experience.  You thought your old settings would work.  Now you have new settings you think will work.  Time for proof in action.

TTL is nice for macro but manual is sometimes better.  Wide angle is often better in manual.  You want to know how to set up your system both ways and have the demonstrated proof before you head out on a trip.


You can test your rig in a dark room, large enough to need full power then get close to things where you need less power.  Both in TTL and manual.  You should have settings that work for both. Once mastered, to the pool to demonstrate it underwater.

That is what I did when I was first setting up my rig.


Just a thought...

Keep most of your old camera equipment and be very disorganized.  She will never notice as more parts are added to the 'pile'.  Never let her see the money handling.  Never explain what individual parts are for, she likely does not care anyway.  Make a big deal of it when you sell old stuff on ebay, not mentioning that you are getting about 30% back from what you paid.


I remember when my wife let me buy my first DSLR setup.  She said, "I am glad to do this for you so we do not have to buy any more camera equipment."  They are so cute when they say things like that.


Lana Turner said it best

A successful man is one who makes more money than his wife can spend. A successful woman is one who can find such a man.


If you give her a lifestyle she is happy with, she is less likely to be unhappy with yours.

While presented in humor, you might find useful facts in there somewhere.

In Topic: Taking pictures of transparent planktonic creatures

I used strobes for all the blackwater pics, also the spotting light on the strobes, also the Sola spotting light.

f9, 1/200, ISO 200 on the camera, manual setting on the strobes most likely but too long ago to recall accurately, using a 60mm lens. I recall being surprised at how much the strobe spotting lights helped the focusing.  Perhaps the different angles when using 3 spotting lights helps because they are not that bright compared to the Sola.


I took a lot more photos that night that I did not share on line, poor focus, composition, etc.  Upon reviewing them again today, my best guess (and it is a guess) is that the portions of the creatures putting out light are also reflective of the same colors in those locations at the time they are displaying.  I got the same colors in the pics that I was seeing in the field, if memory is accurate.


Hope that helps.

One option is to approach it similar to black water dives, similar to Kona's.  Experienced photographers there bring LOTS of light to the subject.  I did one of those dives.  The local's had 4 lights and looked like a freight train lighting up the world.  Your photos would obviously lose the natural ocean colors and have darker backgrounds.  This might not be what you are after but its one option for effect. 

I was using a bright Sola spotting light and 2 Z240's for strobes.

Just some food for thought as I have very little experience in this area to share.


Here is one photo from the Kona blackwater dive to show some results from this approach. 




In Topic: 8 inch vs mini dome with 10-17 and 1.4X question

Thanks for the comments.

I will plan to leave the 1.4x in the bag. Hoping the manta's get as close as Kona.  They rubbed my head as they passed there.  It was quite startling when they did that from behind.


Hoping to see hammerheads too but you never know.
