Lens Filters Explained - Everything You Need to Know

1.  Penapis Terpolarisasi  (Polarizing Filter)

• Filters out polarized light, dramatically reducing reflections, enhancing colours and increasing the contrast. 
• Can be used for any type of photography.
• Polarizing filters are typically circular, allowing for easy control of the effect of polarization.

2. Penapis Ultrviolet (UV)

• Protects the front element of a lens from dust, dirt, moisture and potential scratches.
• High-quality UV filters can be permanently mounted on lenses with a minimum impact on image quality.

3. Neutral Density (ND) Filter

• Reduces the amount of light entering the lens, thus decreasing the camera shutter speed. 
• Useful for situations where motion blur needs to be created (rivers, waterfalls, moving people) or large apertures must be used with flash to avoid overexposure.

4. Graduated Neutral Density (GND) Filter

GND filters ada tiga jenis: soft-edged, hard-edged, and reverse.

Hard-Edge GND Filter :

• Used in high contrast situations, where the sky is much brighter than the foreground and the horizon is flat. 
• These filters are always rectangular (giving the ability to move them in all directions) and are typically used with filter holders.

Soft-Edge GND Filter:

• Used in high contrast situations, but where the horizon is not necessarily flat.
• The soft edge allows for smoother transitions, making the use of a filterless evident. Soft-edge GND filters are also rectangular and are normally used with filter holders.

Reverse GND Filter:

• A specialized filter used by landscape photographers when shooting against the sun while it is getting close to the horizon. 
• While a regular GND filter gradually transitions from dark to clear towards the centre, a reverse GND filter transition from dark to less dark from the centre to the edge.

5. Color/Warming/Cooling Filter

• Colour correcting filters, also known as cooling and warming, colour conversion, or colour compensating filters, are used to correct and/or enhance the colour of your scene. 
• Warming and cooling filters are great for correcting indoor lighting and making your scene look gloomier or sunnier while other coloured filters are great for bringing out certain hues in a scene.

6. Close-Up Filter

• Close-up filters (also known as macro filters or diopters) allows a lens to focus closer on subjects. 
• These filters are only used for macro photography.

7. Special Effects Filter

• Star filters make bright objects look star-like (produce two-, four-, six-, or eight-point stars and light flares)
• Softening/diffusion filters create a “dreamy” look used for portraits, 
• Multi-vision filters create multiple copies of a subject
• Infrared filters block infrared and pass visible light
• Bokeh filters have a certain shape cut in the middle of the filter that makes bokeh highlights have the same shape
