p.1 #1 · What filters...and why filters?


Noticed on several posts comments that noted that the writer had refused to buy the 14-24 (or one of several other lenses) because it doesn't take filters easily.

For my self, I use a Polarizer from time to time (but not on superwides). Other than that, I generally don't need or use filters.

Why are filters important to you, and what do you use that warrants this concern.

Don't mean this critically; but I would like to be enlightened....

Many landscape shooters use split or graduated neutral density filters to control the dynamic range of the scene esp. at sunrise or sunset. It allows you to have both sunlit and shadowed areas properly exposed. You can of course do the same thing now with HDR software but for me at least using a ND filer is a whole lot easier.

ND also to lengthen shutter speeds - for example, to blur moving water or to use portrait lenses wide open in full sun to blow out backgrounds.

I use a Singh-Ray Vari-ND to reduce light, which allows using a slower shutter speed.

Besides (G)ND as mentioned above I use UV filters only for protection in hazardous environments like sandy beaches and a polarizer for dealing with reflections.

Neutral density and graduated neutral density filters are critical for most types of serious landscape work, to tame harsh skies and slow exposures for water motion. It is the reason I dont and wont ever own the 14-24.

I always put a UV filter on for protection of the front element and the filter threads themselves.

The only filters I've found useful are:

1. polarizer. Very, very useful.
2. Graduated ND filter
3. ND filter. I mostly use this with my pre-Civil war lenses because they have no
shutters and I need 1 sec. exposure & use a black hat for a "shutter."
4. Color filters. I carry red, orange, yellow, green filters when shooting b&w with my Leica IIIc
and Rolleiflex MX cameras. These allow me to increase or decrease contrast as needed.

I used to use UV filters on my lenses until I figured out they just don't do anything, and one day a filter broke and scratched up my lens! I use a lens cap to protect my lenses when not shooting.

Yes, and I use it on occasion for warmer/cooler adjustment.

I have assumed that one could apply a filter before a B&W conversion to get approximately the same result. Not much on B&W....

I often use:

1. Circular Polarizer - mostly or landscape shots with the obvious stuff: controlling reflections in water, off of foliage, and increasing saturation from foliage or the sky
2. Neutral Density - I have a range: 3, 4, 6, and 10 stop. This helps with waterfall or seascape pictures to show flowing water. The 3 and 4 stops are also used to bring shutter speed down for flash sync, whenever Focal Plane shots aren't coming out very well (underpowered).

Sometimes I will use ND Grads, but I find that I can use them way less given the dynamic range of modern DSLR's.

Don't hold your breath for the neutral density photoshop filter, it ain't gonna happen. And this is why many serious landscape photographers pass on the 14-24.

"Many Serious Landscape Photographers" are silly. There are filter options available for the 14-24.

Have you ever heard of exposure blending from the same RAW file in Photoshop?

p.1 #15 · What filters...and why filters?


I use four types of filters for different reasons:

1) Circular polarizer ... very very useful in getting rid of reflections and haze, and not just from sunlight.

2) ND filters when trying to slow things down where I want/need a specific shutter/aperature combination and I'm already at the lowest ISO I can go. This happens with water falls quite often.

3) Graduated ND. Not something I use that often, but when I do, nothing else will do, including all the PP in the world ... or maybe more correctly said, 5 minutes fussing with a ND filter saves hours of post processing.

4) Clear glass filters ... for ease of cleaning ... NOT for protection. Some people think a clear glass filter protects the front element ... not really, and if it shatters, it actually is more likely to damage the front element. A lens hood protects the front element better than anything I know other than using caution. BUT, there are times when the clear glass filter is just so much easier to clean that it saves me time for no noticable degridation in image quality. A few examples:

Example 1
Kids by the ocean splashing in waves .... ever get salt water that dried on your lens? Try and get it off that front element ... have fun spending hours cleaning it. With a filter, I can dunk the filter into a sink full of water ... cleans up in just a few minutes of drying. The trick to cleaning salt is copious amounts of water ... more than you want to put on your lens at any one time.

Example 2
Equestrian events on a hot, dry dusty day ... tons of dust ... again, dunk in the sink when done. Only an issue for short lenses like a 17-55 when getting in close to the action ... obviously not an issue for the long lenses.

Example 3
Spray foam fight -- need I say more?

Again, use it on occasion. I'm comfortable with Photoshop. Not great, but comfortable. I want to learn about filters, be they glass, plastic, or gels.......

In this digital age, what do they mean today? Some really great answers here; are their other viewpoints that should be considered?

Why use photoshop if you can get it right in camera? There are many ways to skin a cat, some like one way, other another.

To "get it right in camera" is the lie told by the gear industry. Ansel Adams used to spend days and weeks to "develop" his looks in his wet lab by dodging and burning because he simply just couldn't "get it right in camera." Why use photoshop? You don't have to because anything you do in Photoshop you can also do in the traditional wet lab.

You're thinking of a graduated neutral density filter, which is the "getting it right in-camera" version of exposure blending. A standard neutral density filter however, is for slowing exposure time to create motion, typically in water. This cannot be duplicated in Photoshop. Furthermore, speaking of water, circular polarizers are used by more advanced landscape and nature photographers to reduce reflections of dew on foliage etc to bring out he color underneath. And Once again this being an effect that cannot be replicated in Photoshop.

Its not just the fact that you have to come up with a 3rd party solution to attach a filter. The weight and cost is also prohibitive. There are lighter, more affordable, and more sensible options available. Of course I've rarely accused a fellow photographer of being sensible...
