    Photo Competition #22 - Ends 23-August



    Australia is blessed with some of the darkest and least polluted skies in the world (though if you live in the Big Smoke that might come as a surprise). Anyway, the aim of this competition is for you to produce images of the starry sky!

    Rule No.1
    The submitted photo has to be of the night sky (after dusk and before dawn). Other ground based objects may appear in foreground (and are in fact encouraged), but the primary subject is to be the sky.

    Unfortunately Rule No.1 will pretty much rule out anyone who doesn't own (or has access to) a DSLR and tripod. (P&S cameras simply don't have the manual controls required to take long exposures at night.) To keep this interesting for them, here's:

    Rule No.2
    If you don't own (or have ready access to) a DSLR and/or tripod, you may submit photos of any kind of 'star'. (Hints: star - Wiktionary)

    Rule No.3
    You may submit 2 photos. If Rule No.2 applies to you, then these must have been taken after the commencement of this competition (ie. 12 August 09).

    Tips on how to achieve a night sky image:
    1. Find a dark clear sky (ie. try to get out of The Big Smoke!).
    2. Use a wide angle lens (or the wide end of your zoom lens).
    3. Set your camera onto a tripod.
    4. Set your camera to fully manual, including manual focus.
    5. Try the following settings:
    Exposure: 30 Seconds
    Aperture: start with the largest aperture your lens can achieve, eg. if you have a 18-55mm f/3.5-5.6 lens you'll want to use f/3.5 (at 18mm)
    ISO: try 1600 to start with
    Focus: It will be impossible for your autofocus system to achieve focus on the night sky. It may be equally difficult for you to manually focus through the view finder. The alternative is to visibly set the focus ring on the lens to the infinity position (8). Take a test shot and confirm the focus.
    6. Use a remote shutter release to prevent camera shake. If you don't have one of these, set the auto timer to 2 seconds.

    Just remember if you do intend doing LOOOOONNG exposures over 30" on the DSLR you may get hot pixels. This can happen after about 10-20 minutes. Another way to avoid this is to use PS (or similar) and photomerge/overlay several continuous shots of much shorter duration (e.g. 40 shots @ 30" which equals 20min).

    Now all we need is cloudless skys for the week

    With an exposure of 30 seconds the fraction of a second shake when pressing the button should not matter too much???

    It can. You are basically drawing with light points. If you bump your 'pencil' at the very start, the drawing while not necessarily ruined, can end up a bit smudged.

    It can be done but depends what are the style of the photographer I guess, For that reason I do very little avian photography as well

    For those that are interested in star photos with a normal lens HERE is a good article

    Cheers
