Canon 5d4 novice tutorial

Regarding the steps of Canon 5d4 photography tutorial, I hope these methods can help you.

First of all, it is well known that SLR cameras adopt optical framing, and the focusing system is separated from the imaging system. Therefore, even with the live view function, the autofocus and shooting ability in this mode is greatly reduced. EOS 5D4 also introduced the full-pixel dual-core CMOS AF technology on its CMOS and upgraded it. Therefore, when using EOS 5D4 for real-life shooting, you can get the same control experience as other mirrorless cameras.

Then, Fast Focus supports servo focus (focus tracking), continuous shooting, independent metering system and continuous shooting. As a video photographer, EOS 5D4 has 4K video shooting function. With the help of a full-pixel dual-core CMOS autofocus system, the autofocus capability comparable to that of a mirrorless camera can be achieved. Generally, CMOS only corresponds to one photodiode under the microlens, and dual-core CMOS divides the photodiode under the microlens into two. When shooting, as long as the signals of two diodes coincide, it can be considered as focusing. We can think that all-pixel dual-core CMOS AF is an advanced focusing system for phase difference detection.

Then, although both focusing methods can achieve the effect of fast focusing. However, the focus point integrated on CMOS (occupying diode position) can not complete imaging through phase difference focusing. Its vacancy needs the surrounding pixels to guess and make up, and too many phase difference detection points will inevitably affect the image quality. All-pixel dual-core CMOS AF solves this problem from the hardware level, but the manufacturing process is more complicated. In addition to the application of full-pixel dual-core CMOS AF in shooting, EOS 5D4 also introduced the new function of full-pixel dual-core RAW this time.

Ordinary RAW file records the image information of AB two photodiode combinations. In addition to the above information, the full-pixel dual-core RAW file also retains the information of diode A separately. The purpose of this is to record the depth information of the object. You can understand that the diode AB is a pair of eyes, and the full-pixel dual-core RAW not only retains the subject seen by both eyes, but also retains the subject information seen by one eye A.. We can use the depth of parallax to do some articles.

At present, there are three ways to adjust the full-pixel dual-core RAW: in short, the first way is to shoot a girl and find that the focus is not on her eyes, and she can find the focus by fine-tuning. (But you don't need to take pictures before focusing. The second is to adjust the blur offset, because the depth information of the model is recorded, so the contrast of the photos before and after adjustment is more like a 3D stereoscopic image. The third is to adjust the ghost glare slightly, which is also easy to understand. Usually, if we encounter glare when shooting, the glare will be reduced or disappeared by adjusting the angle slightly.

Finally, the post-adjustment of full-pixel dual-core RAW can only be achieved through Canon official digital photo professional version 4. Compared with the previous products, the hardware of EOD 5D4 has definitely improved. Objectively speaking, the hardware parameters of this camera have no obvious advantages compared with competing products.
