Since childhood everyone is fantasized about stars and sky and if you are a photographer you must have tried to shoot stars sometimes. Well some of you may have got some wonderful jaw-dropping shots but at the same time some of you might have failed in getting good shots due to the lack of proper guidance on how to shoot stars. So here is a tutorial on shooting stars and sky:
Requirements: while shooting the sky you need the following equipments:-
- A Full Frame camera (with better ISO capability)
- A Fisheye lens (to capture wide view)
- A Tripod (for stability)
- Aperture-f/2.8 or f/4
- Exposure-25 seconds for f/2.8 and 40seconds for f/4
Try to avoid lightning sources as they create light pollution, hence shoot them from a location away from city lights. Avoid shooting on full moon ort half moon day as the lightning power of the moon will overpower the lightning capabilities of stars.
The 25 second exposure is necessary because exposures time longer than this would create start trails into the image which is not needed at this point as you want to capture bright, sharp and clear sky. The 1600 ISO is needed for enhancing the low light performance as while shooting at f/2.8 (the max aperture supported by a fisheye lens) the images produced will not be as bright as needed so the ISO of 1600 is perfect as ISO’s larger than this would create noises. If your camera produces noise free images at even higher ISO you can select them.
