How to shoot
After shooting for a period of time, many amateur photographers find their own photos inferior to others or as sharp as a magazine. At this time, many people will choose to purchase a more expensive lens, hoping to shoot beautiful photos. But in fact, this is not the only solution, especially for beginners. This section answers questions on how to shoot sharp photos with cheaper lenses. I personally prefer to use aftermarket lenses, as they are made in Japan.
The photo is not sharp enough:
A.the quality of the lens
B.shutter is too slow and makes the photo blurry
C.shallow depth of field
D.High ISO noise impact
How can you take advantage of cheaper lenses to shoot sharp photos? The secret is to select small aperture.
Aperture is in the tail of the lens to control the amount of light entering the blade. The aperture in addition to controlling the depth of field, also controls imaging sharpness. The reason for this is the spherical mirror and the non-ball mirror theory. If you select small apertures, the image will be more clear and sharp. But we should also note, the lens aperture is not always the same, but are generally in the range of F/5.6 ~ F/11. The sharpest imaging is between the F / 5.6-F/8.0.
Under what circumstances should you not select a small aperture?
1.If shot in low light (night, indoors), but not with a tripod and flash aids, in order to avoid the increase ISO application. The large aperture shooting is better because it increases the light.
2.If the subject of the film is a person, or you want to capture a sense of fantasy, large aperture is used to soften the image rather than small aperture.
3.If you want to have a strong shallow depth of field, the use of a large aperture is better to achieve the effect you want.
Generally, the best aperture is F/5.6 and F/8.0, the best shutter is 1/125 sec and 1/250 sec, ISO 100 or 200.
Different situations necessitate different aperture settings; large aperture will produce a beautiful focal image, and a small aperture will affect the photo clarity and sharpness (especially for landscape shots).
