Are you still unhappy with the sharpness of your images? Isn’t it too much you want?
A digital camera is basically not capable of providing absolute sharpness. Most photo sensors are equipped with a special anti-aliasing filter that slightly blurs the image so that any point of the original scene in all cases is perceived by more than one photodiode. This is called antialiasing (antialiasing) or smoothing and is necessary to prevent moiré-striped artifacts that can occur when photographing fabrics and other items that have a periodic, repetitive structure.

Shutter speed or, as it is also called, shutter speed is directly related to the transmission of motion in images. When shooting still subjects with a fixed camera, the shutter speed does not matter and is determined only by the required exposure. But when either the camera or the subject is in motion, choosing the appropriate shutter speed becomes not only a technical but also an artistic task.
Not to get confused: the higher the shutter speed, the shorter the exposure time than a shutter speed lower the shutter speed longer. Continue reading
No matter how stable your camera is, its stability is completely useless when shooting moving objects. Only a short shutter speed will help freeze the movement. This is why when shooting children, athletes, or even worse, children-athletes, as well as when photo hunting, you often have to shoot with the maximum open aperture and a high ISO value. A noisy but sharp shot is better than a clean but blurry one.
To reduce the impact of movement, use wired photography, and try to choose when the subject slows down or changes direction. Such moments not only provide a clearer image, but are often the most interesting and dramatic. Continue reading
Is sharpness important for a good photo? Yes and no. On the one hand, a technically perfect photo should usually be definitely sharp. No matter how interesting it may be artistically, the vagueness of plot-relevant elements will make it suitable only for an Amateur photo album. On the other hand, if a photograph is technically perfect, but lacks artistic or even Protocol value, then it is not suitable for anything at all. In other words, sharpness is important, but you should think about it only when the lighting, composition, and other fundamental aspects of the photo do not cause you difficulties.
Sharpness is one of the most overrated photographic indicators. Continue reading
Find the aperture value at which your lens shows the best sharpness, and use this value whenever possible (most often it is f/8 or so).
If you don’t have enough light, or if you want to highlight the main subject using a shallow depth of field, increase the size of the aperture, but try not to open it completely unnecessarily.
If the need has come, feel free to open the diaphragm and do not worry about it. In situations where you may need it, the aperture value is not the most important factor limiting the sharpness of images. The wiggle spoils the image much more ruthlessly than any lens aberrations. Continue reading
