What is the 500 rule?
Andrew Patterson The 500 Rule
It recommends that your shutter speed is equal to 500 ÷ Equivalent Focal Length. So, if your full-frame equivalent focal length is 20mm, the 500 rule would suggest that you use a shutter speed of 500 ÷ 20 = 25 seconds.How do you calculate 500 rule?
Basically, to determine the optimal length of exposure, you take 500 and divide it by the effective focal length of the lens (Exposure time = 500/[crop-factor × focal length]). Thus, the shorter the focal length the longer the shutter speed, and the better images you'll get.
What is the 500 or 300 rule in photography?
Rule of 500 (or 300)
When taking an untracked photo of the night sky using a camera on a tripod, this rule tells you how long you can expose before the stars begin to trail. You take the number 500 and divide by the focal length of your lens.
How long an exposure can you take without star trails?
According to this rule the maximum exposure time that will not show star trails is calculated by dividing 500 (respectively 600) by the focal length of the objective. For a 200 mm lens this rule will give 2.5 respectively 3 seconds maximum exposure time.
Why can't you take a picture of the stars?
What is this? The reason you need a remote shutter release for taking pictures of the stars is two-fold. First, even with your camera on a tripod, the act of depressing the shutter button can cause small movements that result in image blur. The remote shutter release removes this problem.
The 500 rule - tested (astrophotography)
Why can't astronauts see stars in space?
Why can't we see stars in the pictures of spacewalking or moonwalking astronauts? The stars aren't visible because they are too faint. The astronauts in their white spacesuits appear quite bright, so they must use short shutter speeds and large f/stops to not overexpose the pictures.
Can astronauts see the Milky Way?
In short, Yes they can! There have been many reports from astronauts stationed on the ISS like Mr Jack Fischer (@Astro2fish) who shared the below video a few years ago. We can see that with the right equipment and enough time, astronauts are able to observe many stars as well as the Milky Way, our home galaxy!
Can you photograph the Milky Way without a star tracker?
All you need is a DSLR, a tripod and a remote release timer. You may want to add a lens hood and a right-angle viewfinder. Capture noise-free images of star clusters, nebulae and the Milky Way without any tracking device.
Can you shoot stars with a 50mm?
Star stacking and separate foreground exposure. Shutter speeds should be limited to 10 seconds or less at 50mm on full frame, and as low as 3 seconds for very sharp pinpoint stars.
What is the ISO for the 500 rule?
The 500 rule for a full-frame camera requires you to set your camera to ISO 3200 or 6400, Aperture to f/2.8 (or as wide as possible) and your shutter speed to 500 divided by the focal length of your camera.
What is the best ISO for low light?
A lower ISO will produce sharper images, and the higher the ISO, the more image noise (grain) will be present. For low light photography, try setting your ISO to 800 and adjust accordingly.
What should my ISO be at night?
For most full-frame cameras, ISO 3200 or 6400 are great for night photography.
What is the best ISO for astrophotography?
If you're just looking for the best ISO to use on your DSLR camera for astrophotography, start with ISO 1600. This is often the “sweet spot” for modern digital cameras, and it is my most used ISO setting for deep-sky and nightscape astrophotography.
What is the best aperture for astrophotography?
A lens with a maximum aperture of f/2.8 or lower is considered to be a fast lens, and is excellent for astrophotography.
How long should my exposure be astrophotography?
You want to use a long exposure time (slow shutter speed) when doing astrophotography, this will give your camera's sensor enough time to record those little dots of flickering light. Usually, a good place to start is somewhere in between 20 seconds and 30 seconds.
How do I use my phone to shoot the Milky Way?
Use a tripod and remote shutter to steady your smartphone camera, choose a shutter speed between 30 en 60 seconds, an ISO of 1600 to 3200, and point to the stars. First of you will need to choose a good night to photograph the Milky Way. Next, check when there is a new moon.
Is Earth in the Milky Way?
We live in one of the arms of a large spiral galaxy called the Milky Way. The Sun and its planets (including Earth) lie in this quiet part of the galaxy, about half way out from the centre.
When can I see the Milky Way 2021?
Generally speaking, the best time to see the Milky Way is during the Milky Way season, which goes from February to October, usually between 00:00 and 5:00, and on nights with a new moon.
How many photos do I need for star trails?
You should shoot up to 200 or even 300 shots to get a decent star trails. Make sure there is no delay between shots (less than one second) because this can cause a break in the star trails rather than a smooth one.
How long should shutter speed be for star trails?
Typical shutter speeds for a star trail range from 15 minutes to several hours, requiring a "Bulb" setting on the camera to open the shutter for a period longer than usual. However, a more practiced technique is to blend a number of frames together to create the final star trail image.
How do you shoot trail lights?

What does space smell like?
A succession of astronauts have described the smell as '… a rather pleasant metallic sensation ... [like] ... sweet-smelling welding fumes', 'burning metal', 'a distinct odour of ozone, an acrid smell', 'walnuts and brake pads', 'gunpowder' and even 'burnt almond cookie'.
Why can't you see the sun in space?
Because space is a near-perfect vacuum — meaning it has exceedingly few particles — there's virtually nothing in the space between stars and planets to scatter light to our eyes.
Can astronauts smoke in space?
Astronauts are strictly forbidden from smoking on board the Space Shuttle or ISS. In fact, smoking was never allowed on Mercury, Gemini, Apollo, or any other spacecraft.
