Broad-clawed Porcelain Crab

My apologies for these not very focussed pics - must learn how to take off automatic and do my own. There might just be enough detail for agreement but we'll see.

Hi Gramandy, The macro (or

Hi Gramandy,

The macro (or preferably super macro) function on your camera would certainly be of benefit in such circumstances.

Is it the same crab in both? I can see what appears to be the grossly disproportionate claw of a BCPC in the first one and the 2nd looks like it might be a Long-clawed PC? It took a minute to locate the crab in the 2nd pic.

Hi, Just thinking maybe you

Just thinking maybe you are using a real camera and my above macro statement isnt applicable? I havent got round to the real camera yet, just compacts. I think there is enough of that pincer visible (its big size in relation to the rest of it) to agree it.

Just using the term real

Just using the term real camera for large proper cameras to differentiate from small compacts. I havent got one yet but must get around to it.

Macro and super macro are just focus settings on compact digitals to snap very small subjects. Can take first class images of invertebrates. Thats as technical as Ive got so far, I select one of 3 focus settings and by pressing a button. 'Real cameras' SLRs etc? I wouldnt know where to begin.

I've only just caught up with this.
Generally, stay away from Super-macro. It is a digital facility on most cameras which enlarges and degrades the optical image.
As for close up work. Many cameras respond well to magnifying glasses held in front of the lens. It needs a lot of practise and the operation to add another arm to your shoulder.
Lastly, it is camera shake or subject movement that ruins most close ups. Raising the ISO setting (NOT by too much) reduces shake and freezes movement - sometimes!
On Auto setting most cameras will set the ISO TOO high for decent close ups. Come away from Auto as soon as you can.
