Filters: The Essential guide to on camera filters
What is a camera filter?
- A camera filter is optical glass, plastic or anything that goes in front of the camera lens to change the way light enters the camera
- Most photographers are sold a UV filter when they buy their first DSLR. It’s like the paint protection when you buy a new car. The best thing to do with your UV filter is to throw it away. You don’t need cheap glass in front of your expensive lens. If you want to protect your lens, use a lens hood and a lens cap
Pre digital era:
- Coloured filters to compensate for different lighting conditions
- 81A to slightly warm images
- Red filters for BW film when shooting people with bad skin
- Softening filter for older models
- Rubbing dust onto a filter to create softening effect
- Various filters compensated for colour shifts, e.g. convert tungsten to daylight when shooting on set
Now many of the filter actions are obsolete because software like Photoshop and Lightroom do such an amazing job.
Are there any filters still worth using these days and how can they improve my photography?
- Reverse ND
- Grad filters
- Variable or fixed ND filter
- A neutral density filter will give you a darker exposure while shooting at a lower f-stop or slower shutter speed
Shooting bright sun outdoors my reading is F22 @ 1/200th sec
- No shade
- Midday sun
- Need fill flash
Shoot at f22 and background is sharp
Add an ND filter to the camera. The exposure remains exactly the same. The light has not changed but the light entering the camera has now been affected by the filter
Change the aperture setting according to the filter being used:
3 stop ND open up by 3 stops f22 becomes f8
6 stop ND open up by 6 stops f22 becomes f2.8
NB 6 stops becomes difficult to focus always set up shot and prefocus before adding your filter.
This scenario also works with studio strobes where it can be difficult to shoot at f1.2 using studio lighting.
Is it best to buy the screw in ones or the square ones?
What about size?
What about cost? Why do some cost $100’s and others $5? What’s the difference?
- Quality of glass or plastic
- Size of filter
- Disposable filters used by film crews
Can you DIY filters?
- 10 stop ND welding glass
- Vaseline over UV filter
- Plastic bag
- Lace over lens
- Dust on UV filter
