What are the entry skills of SLR camera shooting?

Lead: I don't know how to use the new SLR camera? The following are the introduction skills of SLR camera shooting that I have carefully arranged for you. Welcome to refer to!

Tip 1: Learn to use the exposure triangle.

The reason why SLR can achieve distinctive image effect is mainly because of the cooperation of exposure triangle, which forms different visual experience. Therefore, if you want your SLR to play its due role, you must learn all kinds of knowledge and skills about exposure triangle. The exposure triangle is mainly composed of ISO (sensitivity), aperture and shutter speed, and the exposure of photos is also determined by these three factors. Therefore, when making adjustments, you must always pay attention to all the parameters in your mind.

Some friends find this concept difficult to understand. Let's make an analogy. Think of digital camera exposure as sunbathing. If getting a tan has always been your dream, unfortunately you have never succeeded-you always end up with sunburn. Here, your skin is equivalent to the ISO value. Some people's skin is more sensitive to sunlight than others. At this time, the shutter speed is the time you are exposed to the sun. The longer you stay in the sun, the darker your skin will be (of course, if you stay too long, you will be overexposed-sunburned).

The aperture is equivalent to the sunscreen you put on your body. Sunscreen oil can block the sun's rays, and the blocking effect varies with the index. Sunscreen with higher SPF (smaller aperture) will reduce the sunlight reaching your skin. As a result, even people with sensitive skin can stay in the sun for a while (reducing aperture can reduce shutter speed or ISO). As mentioned earlier, this metaphor is not particularly perfect, but it is enough to explain how the shutter speed, aperture and ISO of digital cameras work.

Tip 2: shoot in RAW format

Digital SLR cameras allow you to choose to save files in RAW or JPEG format. JPEG photos have been processed by the camera-saturation, contrast and other settings have been adjusted. But the RAW file can give you a lot of freedom to correct the mistakes in shooting (especially the exposure and white balance). Using software such as PS or Lightroom can make the later photo management and editing easier, and the shooting effect presented is definitely much better than that in JPEG format.

And for photography, manually adjusting the post-effect is also one of the pleasures of photography. Without this step, the fun of photography will be lost.

In short, the RAW format file can keep the original data when you shoot, so even the works that feel like waste during playback may realize the miracle of "turning waste into treasure" with the extensive tolerance of RAW in the later period, and make a blockbuster with visual sense.
