SLR lens problem

Take a photo, absolutely 50? 1.8 is much more suitable than 55-250. But the background is blurred, which must be 55-250 to 250 mm, or the more blurred the background, the better the portrait. . . The best portrait is 85? 1.2L .

As for the bad backlight face, it depends on your metering mode. It can be solved by spot metering+lock exposure. What is the general shooting process? Photometry-lock exposure-focusing-composition.

Small spittoon out of focus is not a special case, and all lenses with large aperture are prone to out of focus. In fact, it is not necessarily that the lens is out of focus, but that the subject or photographer has shifted after focusing. Resulting in a change in the focal plane. For example, when taking pictures of children, they are particularly active. Focus after metering lock, and the child may move when composing after focusing. Because of the large aperture and the depth of the scene, it is very easy to have the so-called "out of focus"? -? This object is out of focus. The real out-of-focus test requires fixed shooting, and there is no problem with the general lens.

To shoot the whole body, any lens will do. Nothing more than watching the distance of retreat. Generally speaking, 50% of the shots are taken by adults, and half of the machines are taken with the whole body, which is estimated to be 5-6 meters away from the subject.

If you have a portrait, more than 600 small spittoons are the best choice. Even though I have changed to 5D3, I still use it with 50 focal length.

These posts are for me to answer others' questions. I hope it helps you, too.

PS: What do the three treasures of the poor mean? Dog head 18-55, long-focus dog head 55-250, small spittoon head. 40? 2.8 Not included. The head of 40 belongs to the category of biscuit head.

Old horse's 50? 1.4 is picky about the fuselage. Because his focus lens is much larger than the general important lens, not all the power supply of the fuselage can fully meet his requirements, so this problem is prone to occur. Is this why the high-end fuselage uses the old 50? At 1.4, there is basically no out-of-focus problem.

In addition, fine adjustment can be made to send the coke to the maintenance department. During the warranty period, non-human factors will be adjusted free of charge.

Follow-up: professional portrait shooting small aperture? Isn't that the corresponding slow shutter? Won't the model blur when it moves?

Answer: I talked about the problem of large aperture and small depth of field before, so you should also know that small aperture is large depth of field. Business portraits don't need any blurring, what they pursue is the sharpness and exquisiteness of the picture. At this time, a small aperture can play a perfect role.

Correct a problem: it doesn't mean that a small aperture must correspond to a slow door. Exposure is a collection of several parameters. As long as the predetermined exposure is reached, the amount of light will be seen. The intensity of ambient light is high, and the time required to complete exposure is short. Commercial photography is mostly done in the shed, and there are generally enough flash lights to fill the light. Even with a small aperture, it can achieve a relatively fast shutter speed.

For example:

Look at this picture, it was taken with the maximum aperture of a small spittoon. Yes, the focus is on the child's left eye. Due to the large aperture, the depth of field is very shallow. The tip of nose and left eyelash are blurred. If the photographer or subject is displaced at this time, it may feel "out of focus". Actually, it is not.

The lens with the shallowest depth of field must be a macro lens, which means blur is particularly good. If you move a little, the focus will be wrong. Look at the picture:

Because the depth of field is shallow at macro, I can only shoot with a small aperture. This was taken by F 16. You can see that the macro depth of field is only 0. A few millimeters. But that doesn't mean it is especially suitable for taking portraits.

Attached are some portraits I snapped. I hope it helps you.

These photos were taken with different lenses. There are 50 1.8, 100 micro, 24-70 F2.8L, ISXXB. Therefore, it has nothing to do with the camera to take a good portrait. You still need to ponder and practice more.

For you, a spittoon should be a good choice. Its only weakness is color. It can be solved by increasing the saturation of one or two gears in the later stage of raw shooting. And reverse connection can achieve the effect of super macro. It can be said that one mirror is multi-purpose. :)

I am a photography enthusiast, and I can communicate more if I have any questions.
