If you already read our article about shutter speed works, you know that it affects both the exposure and motion blur.
Given there are a lot of shutter speed settings available in our camera, it can be a little hard to choose the ideal one for each of our shots.
These two factors have a large influence on your image’s overall looks and sharpness.
If you have no idea where to start, this guide is for you.
What is an ideal shutter speed for our images?
Ideal shutter speed is one that gives us an overall good exposure, sharpness and right amount of motion blur or no motion depending on the type of shot.
Choosing the perfect setting totally depends on what we want out of our images. For example, are we trying to freeze motion or convey a sense of speed? Or we just trying to compensate for exposure?
While I cannot tell you which exact setting you should be using, we can group them into two.
For any types of shots, we can categorically choose between using a fast or slow shutter speed setting.
Shutter speed at 1/50th or above can be considered fast. For the most part, most motion blur are eliminated at these settings.
In contrast, motion blur almost always starts to show anything below this setting. So, we can say that any setting below 1/50th is considered slow.
When in doubt, answering these 4 questions may help you decide:
- If you only want a normal still shot, what is the focal length I am using so I can reduce camera shake blur?
- Do you want to show a sense of speed and motion?
- If not, then do we want to freeze a fast-moving motion?
- And how is the available light? Will using higher or slower shutter speed underexpose or overexpose my image?
Keep in mind that we always have an option to change the aperture or ISO when dealing with exposure.
So it’s not about finding the right shutter speed all the time, but sometimes a compromise between the 3 main controls in your camera.
Let us give you a little more specific situations so you can confidently pick the best setting for your image.
Ideal Shutter Speed for Getting Proper Exposure
When it comes to getting the ideal shutter speed in terms of exposure, you have to first decide if motion blur or depth of field is more important to you at the moment.
This will hugely dictate if freely adjusting the exposure time is even an option.
Shutter speed works together with the aperture to form exposure.
And though ISO is not technically part of the exposure, it still affects the brightness of your final image. And still, an option when compensating the lack of light.
Let me give you some scenarios…
Scenario 1: Capturing an image with shallow depth of field.
If you want to take an image with a shallow depth of field, then you want to keep the aperture as wide as you can, no matter what.
In this scenario, we can ably change the shutter speed to compensate with exposure.
Scenario 2: You want to capture a jump shot.
If you want to capture a freeze motion of a jump shot then you’ll have to use a fast shutter speed so you can eliminate any motion blur.
So on the flip side, if motion blur is more important, then you might want to keep the shutter speed at a certain setting.
This leaves aperture and ISO as your only option to compensate for the brightness.
Compensate with Overexposure:
Assuming we are on scenario one, use a faster shutter speed if your image is overexposed.
Generally, you want to keep ISO low to avoid image noise. So you rarely have to change it for overexposed images.
Compensate with Underexposure:
Conversely, use a slower shutter speed when coping with underexposed images.
But you gotta make sure that you are not using a setting too slow that camera shake can potentially ruin your image if you’re shooting handheld.
Which brings us to our next point we have to consider when finding the best shutter speed…
For Non-moving Subjects:
When shooting non-moving subjects, our main goal is to keep our subject as sharp as possible while having the right exposure.
So the ideal shutter speed in these type of shots is a setting fast enough to cut camera shake blur.
When shooting handheld, you can follow the reciprocal rule to identify the starting point.
Basically, it states that we should use a shutter speed setting faster or equal to the inverse of our focal length. So we need to pay attention to the focal length if we want to do this correctly.
Note that I mentioned “starting point” because we can use an even slower shutter speed setting if we have a good camera hand-holding technique. Lens or in-camera stabilization will also help us reduce camera shake blur.
But if we’re working in low light situations, we may have to adjust ISO as well.
If you can, use a tripod so you can use slow shutter speed. Just keep in mind that below 1/50th of a second will have motion blur if your subject is not completely still.
For Freeze Motion Images:
If you want to freeze a fast-moving motion, use a shutter speed faster than the moving subject.
This will depend on how fast your subject is moving. The faster the subject is moving, the faster settings we should be using.
For Long Exposure Shots:
For long exposure landscape shots, we still want to keep some portion of our image sharp.
So the main goal is to show motion blur on a certain part of your image that you want to attract attention. Like the clouds, moving waters and lights just to name a few.
All this, while keeping the surrounding elements tact sharp.
The ideal shutter speed for these kinds of shots is around 1 second or slower.
Check out my other post about how to do long exposure shots for more tips about this topic.
Anyway, we can’t pull this off without a sturdy tripod since the camera shake blur will be too much.
That said, the more motion blur we want to show, the longer the shutter speed we want to use. For example, waterfalls will look creamier on 10 seconds than on a 1 second exposure time.
For Panning Shots:
With panning shots, you want to have motion blur on the most part of your image while keeping your subject sharp.
To do this, you have to use a slow shutter speed but not as slow as what you’d typically use on long exposure shots.
The best shutter speed setting, in this case, is around 1/15 – 1/60 of a second. This will depend on how fast the moving subject is.
The important thing is that we pan along with the subject’s movement. This will render motion blur which will create a sense of speed. Same as long exposure, you’ll get blurrier motion if you use a longer exposure time
At these settings, camera shake blur will also be apparent so we want to make sure that we are utilizing proper panning.
For Astro Photography:
You’ll have to use slow shutter speed settings because you’d be typically working on an extremely low light situation for shots like these.
Specifically, you want to use the fastest shutter speed you can get without losing too much light. Our planet and the stars are slowly moving so it will produce some motion blur.
If you are shooting solely the stars and no foreground, use the widest aperture. Depth of field won’t be an issue for extreme distances.
If you have to include the foreground, still try to use the widest aperture and try to focus on the hyperfocal distance. If this won’t do due to compositional reasons, use the appropriate aperture to get enough depth of field.
You also need to push your ISO to a setting just before the noise makes the image unusable to compensate for the lack of light.
For Star Trails:
You got to have a lot of patience to show the movement of stars. For this, you’ll be using bulb mode and set the exposure time to around 30 minutes to about 3 hours.
Alternatively, you can also shoot in intervals over a few hours then merge everything in post-processing.
Same as above, you may need to adjust your aperture if you are including the foreground.
For ISO, use the lowest possible you can get.
Note: For both astrophotography and star trails shots, a tripod is a must.
The situations listed above should cover about 90% of the shots you’ll ever take.
But if you want to a little more specific recommendations based on the subject’s speed, continue reading.
Recommended Shutter Speed Settings:
