Help me improve this image

06 May 2014 - 01:37 PM

Hi,

 

This is a pic of one of the wrecks of the Daedalus reef in the Red Sea. I'd love to get some pointers on how to improve it. One of the problem I have is that I introduced noise in the water when I used the channel mixer to add back some reds.

 

The picture was taken with the Sony RX100ii in a Nauticam housing.

 

My best effort:

And a link to the RAW file here: http://jdelage.publi...ng/DSC00324.dng

 

Thank you,

Replicating Channel Mixer in Camera Raw?

06 May 2014 - 09:59 AM

All,

 

I have some UW pictures where I would like to convert some of the blue pixels into red. At this point, there's very little info on the red channel.  On a JPG, I would do that in PS Channel Mixer. How would I go about it in Camera Raw?

 

Thanks,

 

Joss

 


RX100ii in the Red Sea

29 April 2014 - 07:30 PM

I was on the Red Sea Aggressor trip in April 12-19 (it was not actually on the Aggressor boat, but never mind that). It was my first foray into UW photography. I was using a Sony RX100ii in a Nauticam housing, and most pics were taken with two Inon Z-240. Every pic was taken with the Inon WA wet lens + dome. I'll add to this as I process more pics. Feel free to comment / criticize.

Clamps - how tightly before, during, after dive?

03 April 2014 - 10:10 AM

All,

 

I have a NA-RX100II housing on a flexitray II + handle and one Inon Z-240 strobe on each handle at the end of (5"+8+) arm assembly. Today I took my rig in the pool to familiarize myself with it. My take away: it's harder than it looks.

 

One thing that got me puzzled was how much I should tighten the clamps. I found that if I tighten the clamps hard enough for the rig to be semi-rigid out of the water, the arms would be obviously impossible to reposition UW without first loosening the clamps. No big deal, except that fine tuning the clamps underwater might not be the righ thing to do.

 

So what do experienced photographers do with their clamps? What's your "clamp workflow" for in-boat->diving->back-in-boat?

 

Thanks,

Nauticam Flexitray + handle secure?

03 April 2014 - 10:01 AM

All,

 

I have a NA-RX100II housing on a flexitray II + handle and one Inon Z-240 strobe on each handle at the end of (5"+8+) arm assembly. Today I took my rig in the pool to familiarize myself with it, and found that the right handle was getting loose over time. Has anyone else experienced this? It's possible I didn't tighten the screws enough. On the other hand, I need the handle as far away from the housing as possible to manipulate the buttons, and the handle is just held by those two small screws, so I'm worried.

 

Thanks,
