What parameters should I use to choose a camera for taking a bokeh photo?

1,There is no clear regulation of this,Generally, even smaller apertures can achieve background blur,The focal length can be blurred even if it is a wide angle of 18,This depends on how to use it。 2, telephoto is not recommended to buy, the effect is very poor, the picture will be blurry very seriously at a distance, and it is basically unusable, let alone any effect. 3,18-55There is no problem in realizing background blur, and SLR can achieve background blur at will.

4, Canon's SX30 is not good, telephoto machine, telephoto effect is poor, Samsung's camera is very watery, not recommended. The configuration of ordinary SLR cameras is OK, Canon's 500D, Pentax's KX, and Nikon's D3100 are all good.

First of all, if you like blurring very much, then you can abandon the card machine. Second, if it is a telephoto machine, then you have to get closer to the subject, the farther away the background is from the subject, the better the bokeh effect, and the longer the focal length, the better. Thirdly, 18-55 can achieve background blur, but the effect is not good, if you can make the subject in the background farther away, the effect will be better.

Fourth, you basically don't have to think about the card machine, the blur is basically difficult, and all models of the SLR machine are relatively easy to achieve the blur, but you have to consider the lens, I think you should be talking about Canon's SLR. But according to your requirements, it is recommended that you buy a lens, or other large-aperture prime lenses, zoom lenses, that 18-55 sleeve does not do much.

Don't think about telephoto cameras. Personally, I would like to give a good suggestion, if you like to shoot portraits, go to Canon's DSLR, because Canon shoots portraits better than Nikon. Because you are a newbie, it is recommended that you go to 500D or 550D is a good choice.

However, it is best not to buy a kit, because it is difficult for you to grasp the degree of background blur of the camera for the sake of novices. So buying a single machine is the best choice. Then I am matching the 50mm f lens, the price is cheap and only a few hundred dollars, and the imaging effect is also good.

It is suitable for beginners to practice. As for how to use this lens to grasp the subject you require, clear background blur. That is to use the aperture of the lens to control.

When focusing, the focus point is on the subject you want to photograph, so that the subject is sharp. As for the degree of background blurring, it depends on the aperture, and the depth of field obtained by adjusting the size of the aperture is not the same. It's very simple.

Suitable for beginners.

This can be set up as follows:

1. The larger the aperture, the more blurred the background. Below f4 is considered a wide aperture. Such as: etc.

2. The closer the subject distance, the more virtual the bad scene will be.

3. The longer the focal length of the jujube branch, the more virtual the background, as the saying goes: the aperture is not enough, and the telephoto is to make up. Above 55mm is considered a telephoto.

4. The farther away the subject is from the background behind you, the more blurred it becomes.
