None of these has been cropped just few adjustements of WB and levels and then resize for web.
taken with D70s with 50mm 1.4 with extension tubes with/without reversing ring.
some of these I also posted in my build thread so sorry for those who saw them there

shot of the new frags with 17-50 lense for size comparison.

rev ring and 30 mm ext tube. DOF did not cover even one polyp and the coral had to be at few mm from the glass

Green Bird nest I believe?

Green accro ? any better ID?

cool - is the DOF that shallow even closed down? What F stop were you at on these?
 
Shallow DOF is what happens when you point a telephoto lens at an object an inch away. That is just physics, your eye wouldn't do much better.

I was shooting with lens fully closed (16 is the minimum for the 50mm1.4 )
I beleiive the second one was at F11.

this one was taken at 1.4 Iguess

This shot of the green acro were with extension tubes and no reversing ring and aperture was 8 as you can see in the Exif.

Countrary to what most believe DOF is not only related to aperture used. Distance to your subject and focal length have a very significant effect. I remember seeing an online claculator where you key in your aperture distance to object and focal lenght used and it will give you the deapth of field. so even if shooting at F32 or more if you are shooting at less than one inch distance to your subject you will not get DOF. Also Diffraction wll kick in when you use very small apertures giving you a softer image with not much increase in DOF. so basically you go for sharper images.
 
Thanks.
I tr5ied some under my normal tank lighting without flash and others with flash. I'm using a SB800 of camera and sometimes bounce the light of a reflector for softer lighting. When at such closed apertures I can even use the flash without diffusor and stratight on and not see reflections on the glass so that's the easy part of it.
Will also be trying using a multiple flash setup to see if it makes a difference.
the most important thing in coral shots (more than fish) if one uses flash is to use the aperture and shutter speed as if not using a flash (manual) and then either manually limiting your flash exposure to just a bit or maybe experimenting with flash fill mode so that the flash lighting does not wash out coral colours.
 
your welcome..
I need to get a diffuser/reflector - thats a great tip. I usually dont ever try to use a flash- but i hadn't thought to limit the flash duration.

Thanks for your reply and advice.
 
Well so far that's the only problem that I still didn't face with this tank, then again SPS are very new to my tank.
