| Lens: | 16mm @ f3.5 |
| Exposure: | 90 minutes |
| Film: | Kodak Elite Chrome 100 |

| Scanning: | Scanned at 2400dpi. HP Photosmart Scanner using Vuescan 7.1.25 from Hamrick Software. |
| Digital enhancements: | Adjusted brightness and contrast using Picture Window Pro 2.5. Image is resized. |
| Notes: | Even though this was a 90 minutes
exposure at f/3.5, look how dark the sky and the surroundings appear.
Then compare it to this 30 minutes exposure taken
at f/5.6 from Kings Park, Perth (that is 1/3 of the exposure time and
one f/stop slower) three days earlier.
The bright light on the left edge of the image was caused by the headlights of a passing car. The strange red trail on the right-handside was me carrying a red light and trying to locate the camera in order to terminate the exposure :-) |
