7 Frequently asked questions about the use of aperture

Aperture of the exposure triangle is one of the officials, whether you are using full manual mode or aperture priority, you will need to adjust the aperture value, but the use of large aperture and the small aperture, many students will encounter some question, let's take a look at these common problems encountered and solutions it!

(A) When using a large aperture (Example: f / 1.4-3.2)
One problem: the body is not enough sharp

If you have paid attention to our previous teaching, we will know the aperture has two purposes, one is tantamount to control the amount of light entering the second is to control the depth of field. When you use a large aperture, depth of field focus on the front and rear will be smaller, if your camera moves back and forth, it would be very easy to make the body move outside the depth of field, so that it becomes blurred.

On the other hand, the lens is usually in maximum aperture imaging has become soft, the more profound the more entry-shot situation, so to shoot sharper photos, the best is the one to two small aperture close it!

Be careful when using the shallow depth of field impact of large aperture.

Second problem: too blurred background

On a question also explains, will make large aperture shallow depth of field, so that the background is blurred, although this is very useful skill, but when you stop too, so that has become too blurred photo background, sometimes it is not a good thing, think again if you travel all the background photo is blurry, although the photo is very 'professional' sense, but this can not be displayed with the photo you visited some of those places, so it lost significance photo up!
Especially when shooting macro work, to large aperture makes the depth of field is too shallow, you should be careful.

Question three: overexposed photo

If you are using Aperture Priority, or Manual mode, or in the day-lit place to shoot, use a large aperture can make your photo is overexposed, the situation appears 'dead white', especially when your camera's highest shutter fast enough (for example, some cameras only the highest shutter 1 / 2000s), or no chance when ND dimming mirror use will increase, then you will need to collect a smaller aperture to solve.

(Ii) the use of medium aperture (Example: f / 5.6-8)
One problem: the body is not enough outstanding

In the use of moderate aperture, often with background body will be together, failed to highlight the main, this is because the medium can not effectively stop making shallow depth of field, especially in the context of the subject is not too far away, the background will be with the main body as well, plus if you do not deliberately looking for simple background, body will easily 'disappear' in the photo.

Subject not prominent.

Second problem: failure to shoot shallow depth of field

Followed by a question related to a medium aperture is unable to shoot shallow depth of field, shallow depth of field to shoot, remember to have a significant impact aperture, focal length and distance from the background, so if you must use a medium aperture and to highlight the main Please pay careful attention to the choice of background, distance or longer focal length and the background to increase the depth of field effect.

(Iii) when using a small aperture (Example: f / 9-32)
One problem: not enough sharp photos

When using extremely small aperture (such as f / 32, f / 36, etc.), a photo of the scattering of light because of physical reasons become sharp enough, so although generally the small aperture will make the image becomes good, but close too small it will be counterproductive, fellow students must be careful ah!

Second problem: shake

Small aperture will reduce the amount of light if you are holding the camera, it is important in order to pay careful attention to whether the shutter speed 'safety shutter' Otherwise, your photos will be easily obtained because shake blur!

Small aperture leading to the slow shutter, you should always pay attention to 'safety shutter. '

Postscript
This article discusses the use of varying degrees of aperture encounter, though very rudimentary knowledge, but you also have to pay careful attention to the students, so that their use of iris greater certainty!
