xenia crabs: two for the price of one

12 April 2015 - 01:28 AM

Sometimes you just get lucky.  I came across this xenia crab on a whip coral at the end of a 70 minute dive and didn't have a lot of time to work on an image. I was so intent on trying to work around toward the left side to isolate the crab against the water background that I didn't even notice the second crab until I reviewed images on a tablet later!

I also failed to notice that one strobe had turned off, and overlooked the not-so-trivial fact that I had inadvertently left the lens set at f4 from an earlier attempt to experiment with bokeh on some coral.  Other than all that, the shot turned out OK! 

 

Anyway, aside from correcting the obvious rookie mistakes with lighting and DoF, any suggestions for shooting these subjects  in the future would be much appreciated!

 


low light focus tips for Olympus m4/3 60mm macro?

25 March 2015 - 04:30 PM

I've finally picked up the Olympus 60mm f2.8 macro lens and will be diving with it for the first time this weekend.  I need some tips please!

 

Testing around the house last night, the lens can be slow to focus and hunts quite a bit in low light situations. I use a red focus light at night since I'll be shooting mandarinfish which can be skittish with brighter white light and don't allow a lot of time to get the focus right.  I realize I can prefocus but that is tough to get right with a rapidly moving subject.  Is there anything I can do to improve autofocus speed in this situation? 

 

I also notice that even with the focus limiter switch set to the closest range (0.19 - 0.4 m), once it loses focus, the lens will hunt through its full range out to infinity, which doesn't seem right. 

 

BTW I'm using an OM-D EM-5, which focuses very fast with the 12-50mm lens in macro mode under the same conditions. 


Is it possible to test a wet lens above water?

17 March 2015 - 03:27 AM

This is possibly a really dumb question (but I'm OK with that): Can I test a Subsee macro lens on my housing without getting in the water?  My local retailer has the lenses and i would like to take my camera and lenses and housing to the shop to see whether any combination works for me.  I'm a dummy when it comes to lens optics so will appreciate any tips.   


Bohol: recommend a photo friendly operator

05 May 2014 - 05:42 AM

I'll be in Bohol soon on a family holiday and have a couple of days free to dive. I'm looking for a good operator that is accustomed to photographers. Recommended sites welcome too. I'm an advanced diver most interested in walls and pelagics on this trip as I get my fill of macro in Anilao on a regular basis. TIA
