Location:Coolangatta, Gold Coast
General location: Australia, South-East Queensland
The Setup:This is a 4 minute exposure using the the infrared and polarising filter stacked together (for darkest sky).
I have been experimenting with a hack for my camera (400plus - http://code.google.com/p/400plus/). It has a few features like extended exposure bracketing (9 shot), with any length of exposure (instead of the 30 second maximum). It didn't work as I expected it to, but it did go straight to the maximum exposure that I set. I'm sure I just need to read the manual again.
The camera & lens:Filters: Near-infrared (580nm), Polariser
The GIMP -
- Imported to GIMP and used auto-levels (I had intended to do a colour swap, but it didn't look as good as the red version)
- Imported to Lightroom
- Presence: Blacks +100, clarity +60
- Curves: lights +15, darks -25
- Noise reduction: luminance +50, colour +100 (while ISO was set to 100 for minimum noise from signal amplification, the long exposure created different noise from sensor heat)
- Spot removal - to clone out some hot pixels
- ACR lens profile correction for EF-S 18-55 lens
The wash-up:It still eludes me how to get a completely dark sky but it seems to have worked alright.
