In Topic: question about ikelite arms ?!

Hi Mostafa


This looks pretty good to me. The strobes have lit up your buddy pretty well and you could, if you really wanted to, adjust with software his lower half and lighten it slightly. But I doubt any strobe(s) would light up the reef if that is what you are thinking of. 

In Topic: D7200 or .... Sony CyperShot RX100?

Hi Mostafa


I'd suggest you are trying to compare apples and oranges.


The Nikon D7200 is an SLR with all that brings: you can chose lenses, you have TTL viewing, much more precise touch and feel; it's bigger, more expensive but just more flexible and, I would argue, capable. The Sony is a compact camera - fixed lens, not TTL for focussing etc, lighter weight, maybe cheaper but just not as flexible.


Don't be fooled by stunning pics - especially if they are produced for advertising......


Maybe before you splash the cash you need to be clear what you really want:  largish, highly capable, flexible set up - the Nikon; or something smaller, lighter, maybe cheaper, less flexible and, I'd argue, less capable - the Sony.


It's the guy behind the lens that produces the great pics. Not just the camera.

In Topic: Crayfish..... Image dark or just right?

Sorry, no. By "flat" I meant that the range of shades, from black to white, in the image is rather compressed. So there are no real black Blacks, nor white Whites. This tends to make an image looked unlively or "flat". An editing program such as Adobe Lightroom (maybe the most popular for photographers) or Photoshop or Photoshop Elements gives you options for making these changes plus other settings such as Dehaze, Saturation and Clarity which can all help overcome "flat".


Hope this helps.


Camera positioning looks pretty good to me.

Cool image.


I'd suggest it's just slightly "flat".


Are you editing using Lightroom? If so, I'd suggest going into Develop>Basic then holding the Shift key and double-clicking "Whites" and then "Blacks" and see what that does. Or, alternatively, try Effects>Dehaze and increase the setting to the right - and then you might need a touch more exposure.

In Topic: Back Button focus/Nikon D7100

As a Subal housing user I do not use BBF since I can feel the half shutter well with my housing.  With 3D focus I just put the focus spot on what I want in focus, recompose and take the shot.  

I did use BBF on a Nauticam EM-1 housing where I could not feel the half shutter.  




Yep, I'm with you on that one, Elmer....
