8x10 at Hindmarsh River estuary

I've been exploring the Hindmarsh River estuary at Victor Harbor, South Australia. I'd initially scoped  the malaleucas with a digital camera--the Sony NEX-7, handheld:

It's  a low light camera on a tripod situation. 

I returned  for a more considered photo with a medium format camera--Rolleiflex SL66--- using black and white film  and a wide angle lens.  

Now I'm trying to make a 8x10 photo   using the Cambo monorail and black and white film.  I've been waiting for the mouth of the river to open in winter, then for the winter rains to ease so that the swamp-land dries out. It's been  been very wet this winter. I was wanting an overcast day with little wind. 

That was today. I started  the photoshoot with the Cambo around lunchtime,  but the rains returned before I'd really got started.  So I have to wait for the rains to ease, the ground to dry out, and an overcast day.
