So open the aperture as much as possible. Since we want to let in as much light as possible, as described before, it only makes sense to work with these fast lenses with almost open aperture. On my full frame Nikon Z6II * I use the Nikon Nikkor Z 20mm 1.8 *.īoth lenses are wide-angle lenses due to the focal length, which are able to capture a large part of the sky and/or the surroundings with their field of view. ![]() My favorite lens on the DX (APS-C) camera has always been the Sigma 18-35mm 1.8 Art *. Using the right lensįor astrophotography we use very fast lenses, which let in as much light as possible with the largest possible aperture. Shooting timelapse scenes becomes even more complex when you are shooting them within changing lighting, for example from nighttime into the daylight, because you would maybe have to change settings during the shooting to prevent the image from over- or underlighting. You will need a setup timer that helps you to trigger the camera in special intervals. Photographing the night sky with one shot is easy: Setup, point, shoot, optimize settings, repeat until the result fits your expectations.ĭoing timelapse movies is more difficult, and doesn‘t set you free from the steps before. Rather, it is a guide for the basic setting of your setup, from which you can then adjust your equipment so that you get good pictures. This article is therefore not a patent remedy for successful photos. ![]() How much noise an image has at which settings or how much light enters the lens in which time is always strongly dependent on the hardware used. This is photography in general, but nowhere is it as obvious as in astrophotography. A high ISO value ensures that we have to expose for a shorter time, while at the same time a higher ISO value ensures higher image noise.īasically, you can say that astrophotography is the constant search and optimization of compromises. To make this work, we can make things easier with the ISO setting. The trick is to set the camera so that we capture as much light as possible in under 25 seconds. The problem is that we cannot expose infinitely long, because then the stars would no longer appear as points but as lines, after all they are “moving” all the time.ĭue to the Earth’s rotation, it can be said that all images of stars appear as a line when the exposure lasts longer than 25 seconds. Thus, we have to expose for a very long time. When photographing stars or the Milky Way, we have very little light available. This post was originally my own note for photographs of stars or the Milky Way. If Samsung has created a big enough lens and gotten its image processing down to the point it can do this with stars in the night sky – a very difficult proposition, given how little available light there is – it could mean big things for a series of phones already known for having among the best cameras in the business.In this post I write about my basic settings and procedures for astrophotography and creating timelapse scenes. This compensates for the small size of smartphone lenses by gathering light slowly over a few seconds, then processing the image to account for small movements by the person holding the phone. ![]() Most night photography on cell phones is accomplished through a combination of machine learning and long exposure photography. If Samsung has managed to pull off night photography well enough to do this, it says a lot about the light-gathering capability of the 200MP shooter revealed by the Snapdragon 8 Gen 2 leak from December 2022. This is how you get images of the night sky with streaking lines showing the movement of the stars over time. Like a time lapse, it takes many pictures over time, but instead of putting all of the pictures together at the end to create an image that shows, for example, a still city scene with streaking lights, it combines them linearly to create a video.Īs the name implies, an astro hyperlapse simply applies this concept to astrophotography. Hyperlapse, which Samsung Galaxy phones have been able to for some time, is something like the combination of a time lapse and a video.
