Sunrise was at 6:04AM so it was an early 5AM meet at the Long Reef Golf Club (which meant getting up at 3:50AM

I decided to go with a bit of light painting on the reef which thankfully was near low tide leaving the whole shelf relatively exposed with just a shallow layer of water on the surface providing a mirror for the sky.
All I needed to do was find some suitable foreground interest with a good angle on the reef and sky - I found myself a relatively large undisturbed lake of water with just a single large rock in it and set to work.
This was at 5:29AM, so just over 30 minutes before sunrise, which allowed me a long enough exposure (150 seconds) to do some light painting. Shot with a circular polariser and a 3 stop hard ND grad over the sky. I lit this rock using a focused beam from a small (but powerful) LED torch I'd recently purchased for this type of work (it's powered by a single AA battery but puts out a lot of light (a couple hundred lumens) and is focusable). I lit the rock from the left side leaving the right in more shadow and then I used some blue and green EL (electroluminescent) wire to add some cosmic fire predominantly on the right and lapping up and over onto the top.
A little post processing love in Lightroom and here we have Cosmic Dawn
I'd be especially interested in peoples thoughts on this - and any comments/suggestions people would have in post processing?

I tried a handful of other compositions, locations and rocks until about 10 minutes before sunrise but by then it was getting far to light to do this anymore so I headed towards the edge of the reef to catch sunrise and the moving water over the rocks to see if any compositions might work - there were none...
Headed back into the centre of the reef and this area of very shallow still water, the reflections and the barely exposed rock caught my eye. I tried about half a dozen different angles on this from both sides but in post processing I came back to this which was my first shot


A pretty light morning - only 50 shots for the whole session and only a handful even worth touching in post processing
