Notes: the rule was once know as "rule of 600", then "rule of 500", etc. The result is the maximum shutter speed to avoid trails.Īs a consequence, a wide angle lens is better than a telephoto one, because you can use longer shutter speeds before experiencing trails. The calculation of this exposure limit is quite complex (there is a NPF rule that takes into account many parameters, including pixel density of your camera, etc), but usually there is a very easy formula that helps in many cases: take 400 and divide it by the focal lenght of your lens. When you want to take a shot of a night sky, there is a limit on the shutter speed you can set, above which the stars will not be pins anymore (they will appear as small trails). Here my first review.įor all the ones interested in which lens I currently use, my choice is Venus Laowa 15mm f/2 D-Dreamer (a more expensive lens, but faster, sharper, with filter thread, etc.) The rule of 400 But if you plan to buy a dedicated lens, I really suggest you to look forward the great Samyang 14mm f/2.8 (here the Canon and Nikon version): for less than 300 bucks this lens is really sharp, has a very very low coma aberration, and works really well for nightscapes. If you already have a lens that meets my suggestions, go on with it. f/4 is still ok, but do not go higher with f numbers (again because of the rule of 400). The faster, the better: if you can, try and choose a f/2.8 lens. Second, because of the rule of 400 (read on for more details). First, because the composition of a nghtscape is way more beautiful with a wide angle (because of the great attention driven to the starry sky). Read the second part of this article for a practical test (Sony A6000 vs Sony A7R2). This is due to the physical dimension of every single pixel.īut honestly, in practical situations the difference is always smaller, day after day (there are many reasons, for example the general higher resolution of the FF camera, but also the great quality of APS-C sensors). Theoretically, a Full Frame sensor has better performance in low light conditions. Let's start from the first thing many beginners (and not only) ask: the equipment. I really have to do this, because otherwise the discussion won't be complete). * Use specific tools: Sequator (a great alternative to DeepSky Stacker) General considerationsįirst of all, I really have to tell you all the obvious things you probably already read in many other tutorial (yes. but it is not mandatory at all, believe me! Of course, using basic camera and lenses will require you to spend more time in post production. I do not want to lie to you: good equipment always helps a lot, this is true. I will explain the basic principles, and in the second part I will explain how to use "Sequator", a great new tool for image stacking. This is the first of two articles, in which I will show you how it is possible to produce great shots, even with a basic setup and non-expensive gear, working only on an accurate planning and on using the right tools for post production. Do we need an high-end camera? Do we have to spend many many euros for new gear? Seriously who doesn't like these fabulous shots of the milky way, standing beautifully on top of a great subject?!Įvery time we stare at one of those jaw-dropping images, we ask ourself how is it possible to create such clean shots, noise-free subjects and sky, while shooting at high ISOs. But it does not matter what you shoot – landscapes or flowers, animals or still-life – Helicon Focus will make your images stand out.Do you like nightscapes!? I think so. Nowadays micro photography, close-ups, jewelry and product photography became truly dependent on focus stacking. Take several shots at different focus distances instead of just one, and Helicon Focus will quickly and smartly combine the stack into a fully focused image. With focus stacking software you can make your usual camera render results that could not be achieved even with a classic tilt-shift lens. Professional photographers and enthusiasts seeking to keep up with the trend take advantage of focus stacking to create eye-catching images. Today it's hard to imagine macro or micro photography without focus stacking technique. Plain single shots are bit by bit giving place to improved and more sophisticated technologies like HDR and EDoF. Now it's the advanced technology that makes the difference. The digital revolution of the last few years made professional photo hardware widely available and affordable.
