How to change the f-number.
Change the f-number according to your shooting intention.
When the aperture is widened, the f-number decreases.
Check that the f-number has been set to f/2.2.
Check that the f-number is changed.
Conversely, when the aperture is narrowed, the f-number increases.
Normally, the f-number cannot be fixed as desired in[P]mode.
Many people often forget that the amount ofbokeh in a photo does not depend on the f-number alone.
Therefore, the f-number has a direct impact on the degree of bokeh.
If the f-number is increased, both the deer inthe background and the details of the poster are clearly captured.
However, even ifyou use the telephoto end of a standard zoom lens, the f-number at maximum aperture is only f/5.6.
However, by reducing the f-number, both the poster and deer in the background are out of focus, thus making the main subject stand out.
Both the background and the subject were white in colour,so I adjusted the f-number for the subject to stand out from the background.
When the f-number is small, only the eye is in focus while a large part of the skin is blurred, giving a soft impression to the entire image.
It should be noted that this would increase the f-number by a factor of two(reducing the amount of light reaching the camera).
When the f-number changes, it is not only the amount of light entering the camera that changes, but also the size of area in the image that appears in focus.
I took a test shot using Aperture-Priority AE,and checked the f-number and shutter speed at which the background was properly captured.
However, for photos captured from a close distance, such as portraits, the range of acceptable focusis surprisingly narrow even when the f-number is large.
Some users may be concerned about the f-number of the EF16-35mm f/4L IS USM, which has a fixed maximum aperture of f/4.
Your scope of photographic expression will widen and your photography experience can be evenmore enjoyable if you are able to adjust the f-number with a good understanding of its effects!
And because I was unable to use my tripod on the observation deck, the f-number I used would also have to allow me to shoot by hand at fast shutter speeds without any camera shake.
However, before you throw in the towel, be sure to try out the following 3 tips which we introduce in this article-we promise you won't even have to worry about the f-number or shutter speed.
It is important not to lower the f-number excessively, as that may lead the objects in the background to become so defocused that they become completely unrecognizable as a result.
Especially when there is a lot of distance between the elements in the frame that are closest to you and those furthest from you,set the f-number to a large number to ensure that all the elements appear in focus.
When you change the f-number on the camera, or when the camera adjusts the f-number, the size of the aperture diaphragm changes accordingly, which also changes the amount of light reaching the image sensor.
The large f-number(F2.6) projection lens ensures field of depth and provides beautiful projections onto a curved surface as the f-number can be increased with the variable aperture arranged inside the illumination optical system.
In order to achieve a photo with a bokeh effect where the defocused area is so large that the entire area outside the point of focus is intentionally blurred, use the Aperture-priority AE(Av)shooting mode and adjust the f-number to a smaller value.
