How to use the mirror forward function (10 tips for improving picture clarity)
1. Make good use of real-life and manual focusing skills.
Although autofocus is very accurate in most cases, in some cases, such as at night, taking pictures, etc. Autofocus may fail. At this time, we can turn on the live view function = enlarge the picture, and then turn the focus ring until the focus reaches the target.
2. Locking/pre-lifting with rearview mirror
Usually SLR cameras also have a function called quot rearview mirror locking/pre-lifting quot. When the camera is turned on, press the shutter to raise the reflector in advance, and then open the shutter to shoot. This can avoid the vibration when lifting the mirror and keep the photo sharp.

Keep the lens clean.
You are right! Keeping the lens clean can make your photos clearer. Whether it is grease, fingerprints or dust, it will affect the imaging of photos. Therefore, it is best to clean your lens before each shooting.
Use a tripod
This is actually very important for beginners, and many students will also ignore the importance of tripod. Shooting in a place with insufficient light is prone to hand trembling. If ISO is upgraded, noise will increase and photos will become blurred, so a stable tripod is very important.
Regarding the selection and use of tripod, Good Machine Friends Photography has sent a detailed article to introduce it. Interested photographers can read: purchase, use and skills. It is enough for you to read this article about tripods.
Stabilized camera
Use a tripod. When you encounter extreme situations such as shooting in a windy environment, even if you use a tripod, the strong wind will make your camera shake. At this time, you can try to block the strong wind with your body and keep the camera stable.
6. Increase the weight of the tripod and loosen it with a cable.
If possible, hang your camera bag under the central axis of the tripod, which will make the tripod more stable. Now many good tripods also have this function; When you press the wireless or wired camera, please use the cable releaser at the same time to avoid vibration.

7. Use a wider lens
When you use telephoto, slight vibration is easy to show in the photo, so please get closer and use a wider end if possible. However, different focal lengths will also have their uses, so this part is only recommended for you to use when you have a choice.
Don't use too wide a lens.
This seems to contradict the seventh point. In fact, some super wide-angle lenses blur the edge image at the widest angle, so it is best to pay attention to the characteristics of each lens when shooting.
Another way to avoid using the widest angle is to erect the camera first, take a few photos horizontally, and then synthesize a photo in later software such as Photoshop, which is the same as taking a panoramic photo, but only a few photos will be taken this time. This method can not only help you avoid camera edge blur, but also eliminate lens distortion caused by wide angle.
9. Use low ISO
As mentioned above, high ISO will increase noise and make the photos not sharp enough, so if possible, try to shoot with low ISO and tripod!
10. Selection of aperture
If you want sharp photos, the best aperture value should be in the middle of f/5-f/ 10, so we often use f/8 aperture when shooting landscapes. If the aperture is too small, such as f/32, it will increase the refraction of light and blur the photo; However, if the aperture is too large, such as f/ 1.4, it will increase the range of shallow depth of field, and may also cause the subject to deviate from the focus and blur.
You also need to know your lenses and know their optimal imaging aperture. For example, Nicole 14-24 f/2.8 also has a sharp aperture, while Sigma 24-70 f/2.8 will reduce the photo quality at the maximum aperture of f/2.8, so you will avoid using the maximum aperture.
