Hi Tim,
Weird .....................ha ha, wait till you meet me.
The first is kelp well done, it was begging for a close up.
The 2nd is a jelly trapped in kelp.
The third isn`t a wreck

but the pier ladder at Ringhaddy in Strangford Lough.
Christine + Gary went out to the wreck in 20m and had crap viz...hee hee and I stayed in 10m max !!!!
I love the camera but I never remember the settings I use
As you have noticed I prefer the odd photos so macro doesn`t really matter.
We will eventually invest in some software but Christines new camera puts that on hold.
