The Ultimate Guide About Sharpness of Image to Have a Better Control

Sharpness is the photographic term to determine the amount of detail an imaging system can reproduce. The boundaries of tones or colors are the definition of Sharpness. If you do not sharpen images enough, photos will be blurring. Thus, sharpening photos is useful solution to beautifier images to draw others’ attention.

How to take a photo with desired sharpness? What is sharpness setting on camera for and how to adjust the parameter during shooting your photos? How about the photos you have already taken? Just learn more about answers from the article now.


Part 1: What is sharpness setting on camera

Just as mentioned above, sharpness is an important image quality factor, which provides the amount of detail an image can convey. Sharpness is defined by the boundaries between zones of different tones and colors. If there is a clear boundary without gradual, it is sharp, or else, it is blurred. In one word, when you reduce the sharpness, you might get a blurred image instead. Sharpness is measured as a Spatial Frequency Response (SFR), which is also known as Modulation Transfer Function (MTF).

Part 2: How to have a better control over sharpness

If you are a photographer, you should master the methods to control over sharpness. Not only for DLSR cameras, but also smartphone, you have to use a steady or even a tripod and a quality lens. Now here are some important factors that might affect the sharpness during shooting your film or digital.

1. Tripod is a good choice for sharpness

Do not take it for granted that tripod is only used to prevent blurry photos. It also makes sure you can capture the image brilliance and sharpness of which your lenses are capable. When you need to take some shoots with heavy digital cameras or relatively a fast shutter speed, using a tripod is obviously the initial thing to sharpen your image.


2. Selective Focus is a very important factor

Contrast sharp subjects with out-of-focus surroundings. The autofocus on camera is not as smart as eyes. When you take photos in low light, backlight or even rapid change the light, you should choose manual focus instead of AF focus. If possible, you can use the LCD magnifier to zoom in and check focus to be sure for the best sharpness.

3. Shutter speed and right aperture

A fast shutter speed and a wide lens are able to capture more sharpness. But if your subject is human, there are literally a lot of moving parts in each picture and that’s surefire cause of motion blur. As for the case, it freezes the target subject’s normal movements, but it also takes your own handshake out of the equation.

4.Sharpness or image artifacts noise

It should be difficult to define sharpness without image noise or blur. An anomaly of sorts regarding sharpness appears in grain or noise. When the grain become too strong, it obscures details, making sharpness a problem. It is the reason that you have to balance sharpness and JPEG artifacts/image noise.

5. Choose a large size output format

If you are not able to master the above as a beginner, you can choose a large file format, such as RAW for digital camera and HEIC for iPhone. As the large file format stores much more details and sharpness for the shot photos, when the image size increases, the controversy edges that define sharpness will become bigger.
