Buy a good lens
It’s not always your fault that you can’t take a sharp photo. Sometimes its also because you don’t have a good lens. If you don’t take care of your lens it usually gonna reduce the sharpness it can take. Even worse, you can break it.
It also the same with buying an old camera lens. Even though you can attach it to your camera, but usually doesn’t match and it causes an unsharp photo.
For that, I recommend for you keep your lens in check. Or buy a brand new lens, not the second-hand lens.
Well, I didn’t say you have to, but if you can … why not.
Use a Tripod
One of the reasons you can’t take a sharp photo is because your camera is shaking, whether because of your hand or that’s how it is. That’s when a tripod comes in.
Using a tripod can help you have a better shot and control your camera better and easier. And what best is keep your camera still, prevent it to be shaken.
That’s why for landscape photographer whether you are into nature or city and architecture, a tripod is necessary to bring. Because a sharp and precise photo is important.
Use Deep Aperture
Usually, this is what happens. When you want to take a photo all you think about is to have a normal exposure. But in landscape photography that is not the only thing to consider.
I usually prioritize the aperture setting. Because of the depth of field (DoF). It’s basically mean the focus range from your camera that the camera can focus on. So it means you can create more focus image if you using deep aperture, like f/16 or less (the number more higher). But not so deep as far as f/25. I never use below f/18, because if you use a really deep aperture, the result will be less sharpen.
Find a Sweet Spot
In every camera lens there always a sweet spot. What its mean is aperture setting that makes the most sharpen an image. For me, my lens sweet spot is around f/9 or f/10.
It’s not always the same for every camera lenses. The most accurate way to find it is for you look for yourself. Check out the result with a different setting and check out the most setting that works out for you.
Digitally Zoom your Camera
Obviously, it won’t work for an analog camera. But I think this is the best way to have a sharper image. I don’t know how every camera does this. But you can do this if you’re using a digital camera.
With this, you can check if your camera has focus and a sharp right. And you check it directly from your live view or your viewfinder (if your viewfinder is electric).
Even though I said before that autofocus not always work, but the fact remains that autofocus is the easiest way to have a sharp image.
