Have you ever taken a picture that the subject is beautiful, the light is also great but then when you go home to know it was blurred? There are plenty of reasons for this, and here are 8 tips you can keep in mind.
1. Clean the lens thoroughly
Fingerprints or dust on the lens can make the image not sharp, so the first thing we need to do is ensure the lens must be clean before use. You can use a balloon to blow small dust particles, or a microfiber to clean the glass. Also, when not using the lens, you should close the lid before putting it in the bag.
2. Adjust the correct aperture (f stops)
Many new photographers often have the habit of using the largest apertures allowed by the lens. But usually the lens will not be as sharp when shooting at large apertures such as f1.4, f1.8 but at the same apertures as f4, f5.6 and f8.
This happens because the light is traveling in a straight line and the convex lens is 'bent' before it reaches the sensor. When light travels through the entire lens at a large aperture opening, the light will bend more, resulting in purple fringing, blue fringing, and loss of sharpness at the corners. We will see more of this in low or mid range lenses, but generally the lenses are most sharp when we close 2 to 3 steps.
However, the smaller the aperture, the brighter the image. When using very small apertures such as f16 or f22, light will experience diffraction, and the image will become blurry again. In addition to selecting the aperture for the field to match the subject, the user must also remember the physical phenomena.
3. Check the optical quality of the lens
The optical quality of the lens is very important, which directly affects the quality of the final image. According to many, a quality lens is more important than a camera with many 'dots', which have special features.
Save money to invest in a high quality lens (aperture greater than f2.8). Consider switching from using a zoom lens to a prime lens (constant focus). These lenses are generally simple structures, so most have larger apertures and better optical quality than zoom lenses.
4. Consider weather conditions
Believe it or not, but weather conditions do not affect the quality of photos, especially in the distance shots. The vapor from the soil, or dust particles in the air, can completely blur the picture.
The most beautiful day of the day for taking photos is right after the rain, when the air is cool, and the rain has washed away the dirt. If the weather is too bad, you can also take pictures indoors, or where the roof is covered and the air is clean.
5. Depth of field adjustment.
Depth of field is the image area of an image that is governed by focus, aperture, sensor magnitude, and distance from the subject. If your subject is blurry, use a lens with a shorter focal length, use a smaller aperture or move backwards so that the subject stays in the field.Remember, the image field is 1/3 ahead of the focus point, and 2/3 after the focus point, not 50/50. For example, if you take a group of people, divide the group into three parts and set the focus point to 1/3 the previous one, then the second one to get the best one. When focusing to capture a person, focus on the subject's eyes, the distance from the nose to the human ear is also in the focus area.
6. Select manual focus instead of autofocus
Current cameras have advanced focus systems, but sometimes the machines can not be replaced by humans. If in low light conditions, or there are too many things that make the camera's focus system tangle, then you should switch to manual focus. You can also zoom in on large images, or use the Peaking feature to make manual focusing easier.
7. Choose the right shutter speed (Shutter speed)
Another reason why your photos are not sharp is that the shutter speed is too slow, so the picture will shake from your hand. Therefore, choosing the correct shooting speed for each category of photography is essential. If you take fast moving subjects such as children, wildlife, cars, you have to shoot fast, to catch the movement. If static subject, stand still then we can use the tripod and choose slower speed.
Do not be afraid to increase the ISO (light sensitivity) to get the right shutter speed. Still, knowing that increasing ISO will make the picture more noise, the noise will still be valuable if you capture a beautiful scene. As the picture blurred by the hand shake, or not catch the moment, only the water click "Delete" only.
8. Sharpen with post-production software
When a picture is taken, the camera automatically does the picture, but sometimes it's not enough. You can use post-production software, and add sharpness (sharpness) to a photo. Remember, this step only applies to photos that have done the trick above, but can not fix the blurry photos. Also, adjust the focus to moderate, if done 'too handy' will lead to strange phenomena such as noise, halo (border) to make the picture worse, not better.
Epilogue
To have the best possible shot, the photographer must learn to be perfectionist. Before shooting, recap the tips above to see if you've done the right thing, and then one day it will all become reflective, and you take a picture that will sharpen. Remember: "Practice makes perfect."
