The most used filters in nature photography and those that we believe will be most useful to start with are discussed in this article.
Neutral Density Filter
This filter is best for reducing the amount of light the sensor receives without changing the colors of the scene or any other aspect. If you like landscape photography and are a fan of what we call the silky effect in seas, rivers and even skies, this is the objective you need, as it allows you to work at slow speeds in broad daylight. You have them of different intensities as you want to subtract more or less light.
Gradient Neutral Density Filter
This has one half that acts as a neutral density filter, and the other that does not vary the image at all, is simply a crystal. Here you can find both square and round that are compatible with your objective. It is aimed at correcting the difference between the lights and shadows of an image, usually a landscape, that occurs between the sky area and the ground area.
Between both halves of the filter, there is a gradient or gradient that makes the passage from one area to another more realistic.
Polarizing Filter
Another essential filter for nature photography and for photography in general, is the polarizer . This filter increases the contrast between the sky and clouds and, more importantly, eliminates surface reflections.
This will be very useful if you want to photograph a lake, a river, and in general, any surface that is likely to produce a reflection that does not interest you.
Goals
In nature photography, all kinds of objectives can be used, because from macro photography, to wildlife or landscape photography, each of these disciplines needs completely different optics. You can learn more here https://oil-advisor.com/best-0w-20-synthetic-oils/
