Thanks, Larry. The advice from your experience will no doubt help a lot. The Southern Cross will be a good starting point. Just need to get rid of the bright moon.

Larry, that's an excellent suggestion. Only problem is that the Kruger Park is 
off limits at night unless you are a Rhino Poacher or a member of an armed 
response team. I'll look around for a similar anthill outside the park.
If you do it with astrotracer, one advantage of light painting (with a strobe?) is that most of the 
terrestrial image will be "frozen" and just "motion blurred" at the edges. You 
can see that if you look carefully at the edges of the building in this photo I did with the 
astrotracer and K-5.

In the meantime I've ordered a cable shutter release for the K5 so I can use 
the Astrotracer without standing there with my finger on the button!
Did you order one of the dumb ones, or one with a built in intervelometer?  If 
you are using the intervelometer, you need to set the interval to 1 second, 
unless you want to add somethign like 5 seconds to the photo time with 
astrotracer.

Also, there's the question of doing the darkfield noise settings.  The best 
results are probably to do some manual darkfield frames and do the processing 
in post.

BTW, you shouldn't need to hold the shutter in astrotracer, you set the period 
in multilples of 10 seconds, press the shutter with a 2 second delay, and it 
does A/T for the set period.

Perhaps you have suggestion for dealing with the harsh light besides waiting 
for a rainy day? Maybe some kind of filter?
In processing I'd bring up the shadow slider and bring down the highlights.  
I'd try to do my most important landscape images at golden/blue hour time 
periods.  If I was shooting something small, close and stationary I'd try a bit 
of fill, either a reflector or as big of a flash as I could get (don't know if 
the flash would have enough to soften shadows beyond a couple feet).

Alternatively, rather than fighting it, I might try and use the harsh lighting 
to set the mood.  It really does make the area look like  desert.

your photos really reflect the harsh lighing there.

If your nights are clear, I think that the anthill would be an awesome subject 
at night, put the milky way behind it, and if moonlight isn't enough  to 
illuminate it, maybe do a little bit of light painting.  However, I suspect 
that for a variety of reasons that'd be a no-go in Kruger.

PESO x 2: Sand & Sand

Trying it like this. The e-mail won't go throgh.

A large anthill with a built in timber supply & a typical sand river. All the 
tributaries around here look like this in the dry season. The sand beds can be several 
metres deep on top of the bedrock. The rivers still flow below the surface through the 
sand. Elephants dig wells & extract the exposed water with their trunks. The pool 
in this shot is occupied by a solitary hippo.

Scroll L for the other.
