Diving in croatia is great fun and you can enjoy nice diving spots with scarp slopes, lots of fish and sea fans.

Nice nudi shots. I especially like the isolation and dark negative space you were able to create with the first two. Well done.

 

Focus could be sharper on all three but especially the purple flabellina. If you are using autofocus, try switching to a single focus point as small as possible. Aiming to get the rhinopores in focus is often a goal (though your images work regardless and would be worse if you followed that advice).

 

What camera / lens are you using, with what settings?

Thanks :)

 

#1: 1/60, F7.1, ISO 500

#2: 1/160, F11, ISO 100

#3: 1/160, F20, ISO 400

#4: 1/160, F16, ISO 400

#5: 1/160, F22, ISO 100

#6: 1/160, F11, ISO 100

#7: 1/160, F8, ISO 100

#8: 1/160, F11, ISO 100

 

I think most of the blur comes from shake. Most of my macros of the nudibranches were not useable at all because I could not find anything sharp - which is then caused by shake imho. Furthermore I had troubles because of very negative buoyancy so I'm thinking about getting some floating elements for my arms or macro port.

 

The wideangles were taken with a Sigma 10/2.8 fisheye and the macros with a Tamron 60/2.8 (which is a really sharp lens) mounted on a Sony A65 inside an Ikelite housing.

 

As I find it easier to pre-focus manually and then move the housing to focus on my desired object when doing macro I am not using auto-focus (af also hunts a lot when doing macros near 1:1 and there is no focus limiter).

 

But I'm not 100% sure why so many of the nudis are not sharp. I think it is because of camera shake or wrong focus or a combination of both. Sharpness should be reasonable good even at F22.

Excellent photos!

As for the sharpness, try to go for the maximum sync speed possible, to help reduce motion blur - I believe you can go up to 1/250.

Also, find your optimal sharpness aperture. It will usually be sharpest somewhere in the middle, around F11.

Are you using anything to stabilize yourself? In Croatia there's quite a lot of rocky bare areas in the reef to put your finger on and help you be more stable.

Some float arms or foams would be a good idea and relieve the pressure on your arms and wrists.

I just got back from there as well! Nice diving but nowhere near the Caribbean :)

Which area where you diving in?

Thank you!

 

Unfortunately the max sync speed of the A65 is 1/160 - a pure software limitation, as its big brother (the A77) which has the same sensor and processor is capable of doing 1/250. I think the key to better sharpness is more stability.

 

As you said it is nowhere near the Caribbean or Red Sea or many other spots, but when you live in Central Europe it is easy to get there by car for three or four days and gives you some nice diving. I've been at Trogir Diving Center and most diving spots are whin this region.
