Shooting night sky with Nikon d300s using Tokina 11-16mm
Did a simple test with different setting just to see what results I could get with a Nikon d300s and a Tokina 11-16mm lens. Shoot this pictures in RAW and edited them in Photoshop CS5. Noise reduction for high ISO is activated (in camera) and also noise reduction for long exposures. Pretty decent results I think. Think I will try to shoot more at night when I will have the opportunity.
Exposure time 23 s. A f/2.8, focal length 11mm, ISO 6400, manual mode. This picture got pretty overexposed, fixed that in photoshop. Also fixed some noise and sharpening in photoshop.
Exposure 18s, Aperture f/2.8,focal length 11mm, ISO 800. Did not change much regarding exposure in this picture, noise and sharpening in photoshop to a certain degree. The lighter parts of the picture is light from the city that I live close to.
Exposure 23s, Aperture f72.8, focal length 11 mm, ISO 6400. Fixed some sharpening and noise in Photoshop. A little tendency to getting "trails". You can see the bid dipper over the chimney.
