1. learn to be patient
Especially when dealing with landscape photography or travel. You need to wait to get good weather, or a specific sun position. If only this patience is trained continuously, the possibility of getting good results is getting bigger.
2. Find a unique perspective
Sometimes, interesting photos come from an interesting perspective. Subjects that are cliché can even be made interesting with unique and creative angles. Try shooting with ground level (or frog eye) rather than eye level, use the stairs to get extreme angles, and many other ways. Also learn the various angles that might be done.
3 Start using a tripod
The use of a tripod is not only to keep the camera "steady" so as to produce sharp photos, but there are other hidden advantages. By using a tripod, you are "forced" to work more carefully. You will need time to get the right composition, and will think more. With a tripod, you can also experiment with long exposure techniques. Some tripods are expensive, but learning doesn't need to be too sophisticated.
4. Break your habits
Most of us have certain habits in taking pictures: the subjects we usually take, the time we choose, location, composition, to post-production workflows. Try occasionally breaking the habit so you know new things and try new things. Maybe new things actually improve your weaknesses. For example, if you always take pictures in the morning, try the afternoon. Maybe you are even more "familiar" with orange light.
5. Request input / criticism
The key to improving yourself is getting input from others. You can do this by asking the opinions of friends and family, what they like / dislike from your photos. Currently, there are also many mediums to get feedback from people, one of which is through Fotokita.net.
6 take pictures, take pictures, and keep taking pictures
You will never be able to improve yourself if you are lazy to take pictures. So, take pictures often.
