UV Filters and Landscape Scenes

the correct chosen word should be "warm" rather than 'pink'. Skylights were mainly used to help remove the 'cool' cast and give your pictures a 'warm' appearance.

A skylight also filters out UV but not as much as a dedicated UV filter and skylights usually come in 2 slight tints, pink or yellow.

I think you're possibly wrapping all of the "purists" into one big
generalization here.

What some are saying is that we don't get a visible benefit in the
images from a UV filter (this is not the case with a Skylight
filter, which usually turns everything a very fine pink cast).

If folks want and need the protection that a filter can offer, then
that's great. It's an added expense, and particularly new folks
need to know why it is that they are making the purchase.

99.9% of the time you cannot notice the difference between a
picture taken with a UV filter, a skylight filter or without any
filter at all. I have all three, and tomorrow I WILL try to
remember to post some examples. If you take the steps to minimize
lense flare, there isn't much else to worry about. If you're a
purest, that's fine too, but don't do away with the possibility in
situations like I gave examples of above. MANY a-famous
photographer has shot wonderful photographs with UVs, Skylights,
Polarizers, whatever-filter fill-in-the blank.

'this fits me to a T'

I'm going to stick with the layman's term here because that's what the eye sees when you photograph scenes with what ought to be white clouds, white buildings, or white clothing. They turn pinkish in cast.



I call those colors: Clear, Pink, and Peach. )

I used a B+W Gray Graduated Filter at 25%. I used for a short time a cheap SunPak Gray Graduated Filter, I always said they were cheap but needed a gray graduated filter right away and couldn't wait for my order, and it actually fell apart in just one week. The lens piece came out and so did the piece that makes it turn. I wasn't able to get them back inside together. What I did for one day was put the lens on my polarizer and held the bottom of with my finger. It worked okay until I dropped it somewhere in the mud at Indian Peaks Wilderness. So I wasn't able to take it back for warranty. :-( $30 really isn't cheap, just the lens are. It is my second filter to break after a short time of using it. I wish my local camera store wouldn't carry that brand. I have to order online if I want a good brand like Hoya, Tiffen, B+W and Heliopan.

Here's a shot I took that day when I was just sticking the lens on the polarizer.

Thanks,

Lisa

I love graduated ND filters and polarizers. They make a huge
difference in a shot. Are you using a 2 stop grad?

thickness is all relative..........a few mm is a whole bunch of ultra violet wavelengths (less than a micrometer)..........this is the true measure of the ability of a physical device to effect any wave phenoma. If the glass has impurities or inhomogenieties of significant size relative to a wavelength it will adversely impact your photo. How much and can you see the impact, as we say in the science game, "depends."

Can you show an example of this? I would love to see actual
difference in the scene using a UV filter (with the F707) and not
using one. So far as I have seen, there has not been any
difference in the scene and you wind up just adding another glass
interface light has to traverse without benefitting the image.

Show me the money! hehehe

Uh.. sorry.. it was too hazy in orange county last night for me to take any decent shots and show you, i'll try again today from my parking structure at lunch time.

Shay Stephens said:

Sweet, and thank you! I am really looking forward to seeing the
results. I can be convinced, I am not just being a stick in the
mud ;-)

Your're right, size does matter. if the glass was a few nanometers, it wouldnt help much, but being jsut 1 mm should be enough to block ALL wavelengths of UV light (thats what my physcis prof told me). As long as its glass, and we can "see" a thickness to it, it will do the job.

Ann,

Awesome Pano. Did it take 15 shots to make that pano because you
shot it in portrait orientation?

Sorry you misunderstood my original post. The photos were taken by
a lady named Lesley O'Neill. She is en route to B. C. so I cannot
ask why it took 15 shots, but I think it is impressive. Her post
says she does not use a UV filter.

Click to expand...

Having followed the link and read the discussion below the panorama, I can answer the question about the number of shots used. Lesley says that she would at one time have used only about 6 shots for a view like this, but experience has shown that more overlap allows the software to match the images better with more overlap.

Plus you leave yourself the potential to omit one shot if say the sun comes out from behind a cloud or goes temporarily behind a cloud or something like that, and wrecks the exposure/colour balance/contrast of one of the 15 shots.

From my (limited) personal experience of panoramas I would recommend using exposure bracketing, particularly if you have this as a feature on your camera (as Lesley will have on her 707). There's no reason not to unless your last memory stick is nearly full.
