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. For example, if you have a 20-mm wide angle lens, then 500 / 20 = 25.

What is the rule of 500 in photography?

By far the simpler of the two popular rules for astrophotography is 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.

What is the 300 rule?

The rule of 300 is incredibly simple. Simply take your current monthly expenses and multiply that amount by 300. The amount you get is how much you'll need to have saved to keep living the lifestyle you currently lead when you're retired.

When should I use 500 shutter speed?

The 500 rule is used to measure the maximum exposure time you can shoot before the stars become blurry or before star trails appear. Setting the shutter speed for longer than allowed by this rule will result in images that do not have sharp stars.

What are the 3 main value for exposure in photos?

Exposure value is the result of the interaction of the three main exposure basics: aperture, shutter speed, and ISO. It's measured by the light meter, as we will see later. Now, let's see how a basic exposure affects the exposure value.

What is f-stop in photography?

F-stop is the term used to denote aperture measurements on your camera. The aperture controls the amount of light that enters the camera lens, and it's measured in f-stops.

What is ISO and aperture?

Aperture: How big the opening is that lets light in, expressed in F-stops. The larger the number, the smaller the opening. ISO: How sensitive your camera's sensor is to light. The higher the ISO number, the more sensitive to light. Motion blur: Longer shutter speed, lower aperture, lower ISO.

Does the 500 rule work?

The 500 rule can be helpful when photographing the night sky on a fixed tripod. The technique works on images of many focal lengths (up to about 200mm) but can be especially effective when photographing the Milky Way with a wide-angle camera lens.

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's the best ISO for portraits?

For portraits, you want the highest image quality possible. So for the ISO set it as low as you can to avoid excess noise in your photos. Go for somewhere between ISO 100 and 400.

What is the 600 rule?

Exposure Time and the 600 Rule

This rule states that the maximum exposure time of a camera with full frame sensor should not be greater than 600 divided by the focal length of the lens. The rule can easily be extended to non full frame cameras by taking the so called crop factor into account.

What is the 400 rule?

A common rule of thumb to figure out your maximum shutter speed for sharp stars at night is to divide 500 by your focal length. Sometimes it's called the 600 Rule or the 400 Rule or several other numbers that can be used depending on your sensor size.

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 best shutter speed for waterfalls?

For most waterfalls, a shutter speed of around 1 to 3 seconds will suffice. If you use a longer shutter speed, then the white areas within the water may appear too blurred, completely dulling the movement of the water.

What is ISO on a camera?

ISO is your camera's sensitivity to light as it pertains to either film or a digital sensor. A lower ISO value means less sensitivity to light, while a higher ISO means more sensitivity.

What is the best setting for night photography?

While the exact settings will change from picture to picture, the ideal settings for night photography is a high ISO (typically starting at 1600), an open aperture (such as f/2.8 or f/4) and the longest possible shutter speed as calculated with the 500 or 300 rule.

How is shutter speed calculated?

The rule of thumb is that the shutter speed should be 1/[Focal Length]. So if you are shooting with a 500mm lens, you should set your shutter speed to 1/500 or higher. If you are using a DSLR that has a crop factor you have to multiply by the crop factor.

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.

What happens if you increase shutter speed?

When you increase the shutter speed the camera shutter opens and closes more quickly, reducing the amount of light that enters the camera. Similarly, when you reduce the shutter speed more light enters the camera.

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.

What is the Sunny 16 rule in photography?

The rule serves as a mnemonic for the camera settings obtained on a sunny day using the exposure value (EV) system. The basic rule is, "On a sunny day set aperture to f/16 and shutter speed to the [reciprocal of the] ISO film speed [or ISO setting] for a subject in direct sunlight."

How do you balance shutter speed and ISO?

Turn off Auto ISO and set your ISO to the lowest number. If the shutter speed is too fast and you still cannot create motion blur, increase aperture to a higher number until the shutter speed drops to a low number below 1/100-1/50 of a second.
