1. Remember to clean your lens
2.Manual mode
Normally, the white balance might do this to your sunset photos.
Because your phone is trying to balance all the colors in order for it to look as natural as possible. However that’s not what we expect. We’re artists. We don’t want to be restricted by some nonsense.
That’s the reason it’s important to take the time to learn how to shoot in Manual.
Because if you do, you can gain something like this.
You are able to have a similar outcome by changing your white balance to ‘cloudy’, or just by playing around with the white balance on your phone until you get your desired result.
3.Enable the grid lines
It’s an easy way to give you guidance. It helps with the rule-of-thirds. But don’t let it restrict you. It merely serves as a guide.
4.Exposure
Most mobile phones usually overexpose photos. Make sure you adjust it manually to capture the picture you want.
5.Negative space
This is able to lead to more simplistic pictures which can look very pleasing.
6. Keep it simple
When you take the photo, Allow it to be simple.
Don’t overwork it.
Don’t overthink it.
7.Leading lines
A leading line helps guide a viewer’s eye. This is usually done in the form of a road or river, but there are many ways to do this. Just get creative.
8.Avoid zooming in
This can make your photo very pixelated. Try to avoid it. If you must – do it very slightly.
Unless your phone has a telephoto lens(it allows you to zoom in without losing quality), then, by all means, enjoy zooming in.
9.Perspective
You’re taking photos. You’re creating art. Don’t place yourself in a box. Use your imagination. Shoot-up, -down, -sideways. Get on the ground. Climb a tree. Become creative.
10.Get the external macro lens
Buy the cheapest external macro lens you can find. It usually comes with two lenses. One is a macro lens, the other a wide-angle lens.
You could have fun with both, but I enjoy the macro lens the most.
