The Ultimate Guide About Sharpness of Image to Have a Better Control
Last Updated on March 10, 2022 by Peter Wood
Sharpness is the photographic term to determine the amount of detail an imaging system can reproduce. The boundaries of tones or colors are the sharp definition. If you do not sharpen images enough, photos will be blurring. Sharpen photos are a solution to beautifier images to draw others’ attention.
How to take a photo with desired sharpness? What is the sharpness setting on the camera? And how to adjust the parameter while shooting your photos? How about the images you have already taken? Just learn more about answers from the article now.
Part 1: What is sharpness setting on camera
Sharpness is an important image quality factor, which provides the amount of detail an image can convey. Sharpness defines 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. When you reduce the sharpness, you might get a blurred image instead. Sharpness is as a Spatial Frequency Response (SFR). It 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 sharpness. You have to use a steady or a tripod and a quality lens for DLSR cameras and smartphones. Here are some factors that might affect the image sharpness while shooting your film or digital.
1. Tripod is a good choice for sharpness
Not take it for granted that a tripod is 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 shots with heavy digital cameras or relatively a fast shutter speed, you can use a tripod to sharpen your image.
2. Selective Focus is a very important factor
Contrast sharp subjects with out-of-focus surroundings. The autofocus on the camera is not as clever as the eyes. When you take photos in low light, backlight, or even rapid light change, you should choose manual focus instead of AF. If possible, you can use the LCD magnifier to zoom in and check shoot focus to get the best sharpness.
3. Shutter speed and right aperture
A fast shutter speed and a wide lens can capture more sharpness. But if your subject is human, there are many moving parts in each picture. And that’s the surefire cause of motion blur. As for the case, it freezes the target subject’s movements, but it also takes your handshake out of the equation.
4.Sharpness or image artifacts noise
It should be hard to define sharpness without image noise or blur. An anomaly of sorts regarding image sharpness appears in grain or noise. When the grain becomes too strong, it obscures details, making sharpness a problem. It is why you have to balance sharpness and JPEG artifacts/image noise.
5. Choose a large size output format
If you can't master the above as a beginner, you can choose a large file format, such as RAW for digital camera and HEIC for iPhone. The large file format stores more details and sharpness for the shot photos. When the image size increases, the controversy edges will become bigger and bigger.
Part 3: How to apply a desired sharpness as after effect
What should you do to sharpen a photo you have already taken? Does it mean a sharp image is better than a blurred one? Having control over the MTF is very important. WidsMob Retoucher should be the ultimate solution to balance sharpness and noise.
