I looked at your albums and you are clearly at a specific point in the photographic path.
You can work the camera and get decently exposed pictures but you actually know little about what makes a picture good beyond some technical issues.
There is one rule and three corollaries that I go by.
The rule is always know exactly what you are taking a picture, what is important and what isn't.
The three corollaries are:
- Put important things in important places
- Maximize aspects of the photo that improve the imapct
- Minimize aspects of the photo that detract from the impact.
In most of your shots, you've pointed the camera and pressed the shuuter, seemingly without too much thought.
Look at the pictures of all the people, all in the center, losing all the relation of them to their environment.generally aware and interacting with you and very little with their environment.
In the animal pictures there is one that is a very good example of missing the point.
Most of the right side and much of the top is not contributing and the maonkeys, that should be important are darker than anything.
Framin it so that the monkeys are more prominent and much of the rest is cropped away makes the shot much better. You are hindered by the DOF, this would have been wonderful shot at f2.8, thus throwing the stature more OOF.
Decide what is important then frame, compose and edit around that.
Ditto the seal lion
The animal was dark and everuthing else was brighter.
Lots of empty space.
Crop so that the shapes of the rocks and the animal reinforce each other, lighten the animal, dark everything else.
The camera is working fine, now it is your turn to learn about composition and editing so that the picture on the screen matches the one in your head.
There are no shortcuts, just work and experience.
