​10 wrong actions will destroy good photos

1. Keep tripod on when using

More and more advanced anti-shake technology, canvas prints so that the threshold to take a good work becomes lower and lower, of course, there are a lot of photography enthusiasts will whether anti-shake as one of the important indicators to buy equipment. Everything has two sides, so does photography.

To give you a better idea, let's talk about what anti-trembling is all about. At present, online canvas prints the anti-shake structure of most lenses is composed of a gyroscope and a floating lens. The gyroscope detects jitter and reminds the floating lens to make corresponding reverse compensation, so as to achieve the purpose of anti-shake.

When shooting with a tripod, the camera can also detect high-frequency vibrations caused by the camera's reflector lifting and shutter opening and closing. If the anti-shake system is still in operation, the floating mirror will move and change the optical axis accordingly, aluminum photo prints but the camera is still at this time, which actually reduces the quality of the picture. Therefore, in the use of tripod shooting, it is best to turn off the anti-shake, and open the reflector prelift, to ensure the quality of the picture.

2.Below the safe shutter speed

The concept of a safe shutter speed is no stranger to anyone, and is theoretically the inverse of the focal length of the lens. For example, shooting with a 50mm fixed focus on a full-frame camera yields a safe shutter speed of 1/50s. That is to say, the shutter speed should not be lower than this value when shooting handheld, otherwise the probability of paste is larger.

In particular, it is important to remind users of non-full-frame cameras that the safety shutter is based on the equivalent focal length, and do not forget to multiply by the lens equivalent coefficient. In addition, the safety shutter is not suitable for shooting moving objects. Shutter speed should not be lower than 1/320s, of course, this is only a safe value, if the car is a high-speed moving object, and it is recommended to use higher speed.

3.Big aperture is everything

A large aperture can provide attractive out-of-focus and good shallow depth-of-field visuals, but it's not everything. A lot of people "believe" that the big aperture is everything. For example, when shooting a portrait with a large aperture (such as f/1.8), it is easy to blur the edges of the face if the focus falls on the eyes, and inexperienced photographers will not zoom in to confirm the focus on the camera. In fact, the aperture is relatively large, not only the aperture full open to call the aperture.

The choice of aperture and focus is important if the photo is to be used for a very important purpose. In general, beginners can use f/5.6-8 aperture more, which can not only show the best image quality of the lens, but also increase the chances of taking good photos. Why not?

4. High sensitivity is rarely used

In the film era, sensitivity refers to the sensitivity of the film to light. In the digital era, the photosensitive material of the camera has been replaced by different kinds of sensors, but the definition of sensitivity is still much the same, that is, the sensitivity of the sensor to light. There are two ways to improve camera sensitivity. One is to force the brightness and contrast of each pixel. The second is to use a number of pixels together to complete the original as long as one pixel to complete the task.

As for the claim that improving the sensitivity will lead to a decline in the picture quality, we need to consider the actual situation. Now most digital products, especially the high sensitivity performance of medium and high-end SLR cameras, can meet the needs of most enthusiasts for daily shooting. At this time, we need to have a new understanding of high sensitivity.

Every day when shooting is not ISO 100 can be used to complete all the scene, we also introduce the four need before use of high sensitivity, low light environment we need to use the ISO 800, ISO 1600, and even the ISO 3200, Ago Gann in photography is not a "box", cooperate with the late for noise reduction processing, using software will make your photography level to the next level.

5. Shoot on the move

During the journey, taking a photo becomes a very mechanical activity. Many people press the shutter button before they can even stand on their feet. Many people become photographers because they respect images and think about photography.

When taking daily photos, take every scene seriously and spend enough time observing and thinking. This kind of shooting practice is what most beginners need. A lot of shooting is important, a lot of fine shooting is necessary.

6. Over sharpen

Sharpening is a necessary part of post-processing, but we've seen too many photographs that have been oversharpened. As our digital cameras become more and more pixilated, sharpening requires special attention. Over sharpening can make photos look hard and fake, giving a sense of distance.

No matter what kind of software is used for sharpening, it is recommended that the radius should not be set too large; otherwise the photos will look stiff, especially when dealing with portraits.

7. Resize the photo after sharpening

Sharpening should be placed in the last step of the whole post processing. It is recommended to adjust the contrast, brightness, curve and other parameters before this.

8. Wrong understanding of color space

Colour space is called gamut again, can understand to be color range, rich degree actually. In descending order, they are ProPhoto RGB, Adobe RGB, and sRGB. You should choose the right color space according to the output needs of the photo. At present, most beginners do not know the color space, and choose sRGB regardless of the use of the photo, which is an incorrect approach.

Adobe RGB is a color gamut standard launched by Adobe. SRGB was jointly developed by HP and Microsoft in 1997. Compared with sRGB, Adobe RGB has a broader color space and contains CMYK color gamut that sRGB does not have. ProPhoto RGB has a larger color gamut than Adobe RGB, so digital printers currently cannot recognize this color space, which is only used by professional photographers with high requirements for image output.

The color space is actually related to the purpose of the photo. In normal web browsing, only sRGB is basically displayed. It is recommended to switch to Adobe RGB for larger output for richer color details.

9. Almost no exposure compensation

Exposure compensation is a very important parameter, especially in aperture priority mode. Want to make clear, still want to teach everybody to measure light principle of camera first. Regardless of the brand, the camera is measured in 18% gray. However, in daily shooting, it is almost difficult for us to encounter the object being photographed with a brightness of 18% gray, so we need to manually calibrate the light measurement of the camera, which is the significance of exposure compensation.

For example, when shooting snow scenes in winter, there are many shooting strategies will recommend increasing exposure compensation. This is because the camera takes 18% gray as the standard to measure the light of snow, but in fact the snow is brighter than 18% gray. If you do not manually increase exposure compensation, the snow scene is likely to be gray. On the contrary, when shooting dark objects with lower brightness, reduce exposure compensation to ensure correct exposure. This is what we usually call the "white plus black minus" principle.

10. Do not check the camera parameters before shooting

Some photographers have a good habit of returning the camera parameters to the default state at the end of the day in case they forget to adjust the parameters during the next day's shooting, which not only wastes time, but also misses many wonderful moments. Details determine success or failure. If you want to improve your photography skills, start with these small things.

Finally, I would like to remind you that although digital postproduction can help us to take a good work to the next level, a rigorous attitude is needed in the early shooting, because any post-production is based on a good photo. In addition, in the post-processing process, details are often overlooked. If you try to enlarge the photo 100%, you may find some problems. Finally, although photography theory is important, practice is the only criterion to test the truth. No matter what your current level is, take photos and find another kind of beauty in this world with your camera, photographs printed on aluminum so that you can experience the pleasure of photography.
