Stars in Daylight: An Astrophotography Technique

Stars in Daylight: An Astrophotography Technique


   
    Look at the photo... It looks like a fairly clear afternoon sky, but here's the catch - when you look at 
    it closely, you see dots in it - and a lot of them. They are Stars

So how do you go about getting a photo of the night sky with stars, like an afternoon sky? Well read along...


So the main factor that plays a role in your image's brightness is the shutter speed. Having a higher shutter speed makes your image brighter, and having a lower shutter speed makes it darker.

ISO is the next major factor. You can think of it as the how you brighten or darken an image on your phone while processing it - you are not taking a brighter photo but you are making it brighter (well that's an analogy to roughly make my point)

The last deciding factor would be the Aperture. This does not play a huge role, but having a low 
f-number  would help your image be brighter


So
How to get an afternoon sky from the night sky?
Well... Get a really bright shot - that's all...
Now, How do you go about doing it?

Well...
1) A slow shutter speed makes your camera stare at the sky for longer, thus helping it see more.
2) A moderate ISO - Why do I say moderate? Simple - usually in most cameras, the image noise is proportional to the ISO - so, you wouldn't want a really noisy image - it beats the whole afternoon effect.
3) The widest aperture possible (lowest f-number)

The camera & settings I used for this photo- 
Nikon Coolpix P950
15s
ISO 800
f3.5
