Introduction of camera hiding function

There is a saying that the old model always has fewer functions than the new model. But reading the instructions can help you discover the potential of old cameras? New features? . There are often some interesting things hidden in the appendix of the camera's instruction manual or the custom menu. In addition, some special functions are hidden in the random software.

Camera hidden function: lens correction

There is no perfect lens in the world. The lenses produced by top optical manufacturers will also have image distortion, excessive attenuation of light at the lens edge or low resolution. More and more digital SLR has built-in lens correction function, but using this function may cause chromatic aberration, reduce image clarity and trim image edges. In some models, this function is part of the RAW file editing menu.

Note: In some cases, this function only applies to the original lens.

Tip: The lens correction function is set to on by default on some cameras and can be turned off in the relevant menu.

Camera hiding function: add recording notes to photos.

Many digital slrs have microphones, which can be used to record audio when shooting video. This small attachment can just add audio notes to photos. Voice notes can add more content to photos than EXIF information. For example, the name of the person in the photo, the shooting location and how to find this place.

Tip: You can add the following recording: Why don't you come back before the fog starts? Or? Arrive early to catch the first sunshine on the mountain? .

Camera hidden function: interval shooting

Strangely, many small digital cameras have built-in interval shooting function, while digital SLR can only be realized by connecting a timed remote control cable. Fortunately, the newly launched SLR is also equipped with this function.

Time-lapse photography needs to take hundreds or even thousands of still photos. Therefore, video editing software is also needed to make time-delayed short films.

Tip: In order to ensure the shooting demand, it is best to install a fully charged battery or use an external power supply before shooting.

Camera hide function: digital filter

There are many digital filters built into the SLR, but many people are unwilling or unable to use this function, which is too tacky. In fact, these filters still have great playability.

A variety of filters are built into the fuselage. The shift-axis mode can provide photos with the same miniature landscape effect when you shoot the city scenery, thus saving you a sum of money for buying shift-axis lenses; Soft focus mode can beautify the skin; A crayon or watercolor filter can adjust the strong highlight overflow at noon. However, remember that the filter effect only applies to photos in JPEG format.

Tip: When taking black and white photos, it is best to check the photo effect under different filters. Black and white photos taken with green, red or yellow filters will have different effects.

Camera hidden function: TTL flash exposure lock

Just like the exposure lock function on the fuselage, TTL flash exposure lock will let the photographer do a pre-flash metering on the same scene or area first, and the flash will adjust the flash output intensity according to the metering value after exposure value lock. When the photographer wants to shoot people or things on the edge of the picture, he can use this function to ensure the consistent exposure of the photos taken. What the photographer has to do is to re-compose the picture.

Tip: TTL flash exposure lock can be used online with other flash with TTL function.

Camera hiding function: customize JPEG photo style

Different camera manufacturers have different names for this function. For example, Canon calls it photo style, and Nikon calls this function photo setting, which often has several styles built in: natural, bright and so on. But here we call it JPEG option: it can fine-tune JPEG parameters (saturation, sharpness, contrast, etc. ). These parameters can be adjusted independently, and the adjusted style can be saved as a configuration file, even on a memory card or shared with other computers.

Hide camera function: enhance dark details with dynamic range expansion function.

Different manufacturers have different names for this function. For example, Nikon calls it D-lgihing and Sony calls it D-Range, but the purpose of these functions is the same: to improve dark details without highlight overflow (different from HDR function on some cameras). Using the original software to optimize the RAW format photos can also achieve the effect of dynamic range expansion.

Tip: Don't rely too much on this function. Some dynamic range expansion functions can improve the details of the dark part and also increase the noise of the dark part.

Camera hidden function: electronic level

Keeping the horizon level is the key to landscape photography. When a hand-held camera uses the viewfinder to take landscape photos, it is best to turn on the grid line indication in the viewfinder. You know, even experienced landscape photographers will occasionally take pictures of the horizon tilting, especially when the horizon fluctuates.

In the field of architectural photography, if the photo is tilted with reference to the horizon, the photographer may need to cut off part of the edge of the main building when editing the image later, and the integrity of the whole photographic work will be affected. The electronic level built into the fuselage allows photographers to devote all their energy to composition shooting.

Tip: Photographers usually take a lot of photos of landscapes and urban landscapes by hand, and often use vertical photography. The built-in level of the camera can help the photographer shoot the landscape at the horizon level.

Camera hiding function: processing RAW format files.

In fact, there is no need to use special image editing software to process RAW files. Is there a built-in digital SLR? RAW to JPEG? Function. Before using the conversion function, you can also make some general adjustments to photos, such as white balance adjustment, brightness adjustment, contrast adjustment and changing JPEG file options.

After editing the RAW file, you can generate JPEG photos and keep the source file. If you save in JPEG format, you can hardly make any changes to your adjustments.

Tip: If you go out for a long time and don't want to bring a notebook, you'd better bring more memory cards. Take photos in RAW format, then choose your favorite photos in your spare time, and then convert them into photos in JPEG format.

Camera hiding function: use online shooting function to view photos remotely.

At present, the mainstream digital SLR can control the camera on the computer and display photos in real time. The software to realize this function is usually placed on the attached CD, such as Nikon's camera control pro.

Tip: As long as the data cable is long enough, you can put the camera outdoors for remote shooting.

Camera hidden function: Dust removal wizard helps to clean the sensor.

Although the camera's sensor vibration function or air blowing can be used to remove the dust on the surface of the low-pass filter, it still cannot be completely removed. Therefore, the dust removal wizard function can be used to help remove the fine dust remaining on the low-pass filter.

Using the dust removal wizard, you need to take a photo with a uniform white background, and a dust distribution map will be generated through certain calculations inside the camera.

Tip: Take precautions first and try to replace the lens in a clean place. When the camera is idle, be sure to install the body cover, and the front and rear covers of the lens should be installed to prevent dust from entering.

Camera hidden function: reflector pre-lift and delayed self-timer.

Even if the external cable releaser is connected, the vibration generated when the reflector inside the camera is lifted will still affect the shooting quality. Therefore, it is best to use the pre-lifting function of reflector to shoot long-exposure works. At the same time, hands are another source of vibration. In this regard, you can use the delayed self-timer function, and the camera will automatically shoot after pressing the shutter for a period of time. Using these two functions at the same time can effectively solve the problem of picture jitter when shooting long exposure works.

Tip: When shooting slow shutter works by hand, you can also use the reflector for pre-lifting to reduce the picture jitter. When shooting, lean your elbows on a stable place, hold the camera, take a deep breath and press the shutter. Keep your body still during the whole process until the shutter opens and closes.
