Does that mean there will be a larger unnoticeable difference?

Thanks, all. Actually, why I was asking was that one day, traveling home on leave on a Greyhound bus, Canon 1V S2 rangefinder camera, 50mm lens, sky1A filter, probably Ektachrome 100 film...I took a photo through the windshield. The filter eliminated much of the windshield's green tint, making the color balance better. Just wondering if the 1A might have the same effect on digital.

If in AWB, optimally, the camera should internally adjust to compensate......and the use of color compensating filters should be redundant and un-necessary. YMMV 8-)

Cataract Symptom: (Color Changes) Your vision may gradually take on a brownish or yellowish tinge. At first, you may not notice this discoloration. But over time, it may make it harder to distinguish blues and purples.

Best advice? Always shoot a color target with each and every setup for commercial work... No worries then...

Disclaimer:
While "Cataracts" can (and typically do) cause changes in color perception as they progress. However the variability may be due to pupil size, lighting or dry eyes. Most likely these symptoms are due to progression of your cataracts. However, please consult with your ophthalmologist to confirm this because retina and optic nerve problems in the back of the eye can also cause these changes. (issues with your retina and/or optic nerve are serious and require timely medical intervention)

As for Pupil Size? If you've been in this craft long enough you likely realize that a "fast" prime or zoom will typically experience maximum Chromatic deviations at their maximum aperture... Don't believe this? Then I suggest you invest quality time on DxOmark (enough said)

Below is an image of a very "Fast" aperture a.k.a. Pupil Size ideal for low illumination levels in which optical and color distortions abound... However your eyes relay their input through an amazing data analytical component (your brain) which alters your "perception" of what your "eyes" actually capture at astonishing speed in real-time corrected to what your mind has been programmed to accept as "real"... Which is why your perceived color balance isn't highly accurate... Shoot color targets, to get color balance right.

Most importantly Please Protect your cherished sight by having your eyes examined by licensed medical practitioners at the recommended intervals for your age group.

Wishing all a marvelous journey in photography and stellar health. Cheers! Thomas

I'm odd, I prefer the "as shot" shot.
I'm primarily looking at the planes, not particularly the clouds.


That's what I am thinking, too! Thanks CHG_CANON and Thomas for the examples! Fyi... after my double cataract surgery several years ago it looked as if a dingy yellow filter had been removed from my eyes, and ~2 stops of light had been added!

Yes I did eventually read the text, and good points all.

You don't need and shouldn't use those filters with a digital camera. They will cause a color cast that you will need to remove in post processing.

My eyes must be shot, I don't notice it.

Correcting color balance of digital images negates any worries about the tint of these filters. Only 2 things matter to me:
1) Although a filter won't protect a lens in a bad fall over it will protect the lens from smudges. Go ahead, wipe it with your t-shirt after you've spit on it. So what? It's expendable.
2) Buy a decent filter. Would you put a junk filter on your $2500 lens? Spend $100 on a decent filter for heaven's sake.

What's the resultant visual image difference between a $35 filter and a $135 filter (other than $100)?
I know, the charts and graphs say it's different, but can a person actually tell looking at an image?

I guess it depends on how closely you look. When you enlarge your images enough to make a 30x45 Inch mural for the wall even the slightest defect will become apparent. Does it matter to you that the leaves on a background tree in your landscape art are visually distinct? Do you shoot from a tripod using a 3 second shutter delay to allow the camera to dampen out the vibrations of the mirror snapping up? Sure, the average viewer (takes pictures with his cell phone) will not examine your work closely enough to appreciate your dedication to detail, but who are you creating your images for in the first place? I think that's the difference between commercial photography and artistic photography.

I guess it depends on the filter and the person looking. I have definitely seen noticeable differences such as color casts, reflections, on cheap vs more expensive filters. YMMV.
