The 18.87 mile distance from the top of Cadillac Mountain across Mount Desert Island to Blue Hill on the other side of the Narrows is shown in Infrared, Visible and Ultraviolet light. There is always a certain amount of marine humidity in the air. The IR filter cuts right through that for a crisp, contrasty view. The UV filter just barely makes Blue Hill visible.

Your IR shot is simply gorgeous. :-)

Wow fantastic! IR really is the best for landscape, but UV has a kind of "alien world" look that I like.

I like them all. I especially like seeing the differences between each.

An excellent and instructive comparison. As usual, the IR comes out looking really good for this kind of use.

I like all of them too! Am partial to the hazy UV one.

However, if the point was to comment on Hornblende's cityscape, the distances here are probably not comparable! Yes, if you have a horizon that's far away you will see the haze more in UV than IR, but the actual distances matter quite a bit! (And so does the day you take the photo on.)

Here is one from last year that I took:

Thanks everyone. I enjoy shooting these scenes using the different filters. I have some more of this particular one which I'll try to post.

Andy, agreed -- about distances, etc.

I'm not sure where the UV haze thing begins to set in as a general rule (if there even is one....). Quarter mile? Half mile? Less? More? The film guys should know because they were big into using UV-block filters for the haze problem in landscapes. I have a hazy UV of some cows from which I was about a football field away. But then it could have been the methane....... :D :D :D

I note that UV-blocking did not do my visible shot much good. It is also a hazy. Just from heat/humidity I suppose.

Here are some samples from other filters. These are 421 pixels wide, so if your browser is expanded some of them will appear side-by-side for comparison purposes. They also look better in an expanded browser.

These are edited simply to please myself. You might obtain different false colours or another "look" entirely.

Unfiltered
White balance on clouds. Lots of IR in this of course.

IR 092
Fotos made with this filter always click-white to a lovely blue.
The sky could be darkened for a more IR-ish look. The clouds should be brightened a bit.
You are permitted to do that to overcome the lack of dynamic range in the typical digital camera.

AndreaU-Mk1
The 1st blue/magenta foto is not white balanced, of course. For the 2nd foto, after white balancing,
I pushed the saturation up to bring out the false green which is often found in UV landscape scenes.

Lime and violet-blue, woo!

UG5 + S8612
Passes UV+Green+Blue, but I didn't get that from it for this distant landscape.
The 2nd foto was white balanced on the clouds.

BaaderU, again
After white balancing, I pushed the saturation up (2nd foto) to bring out the false green which is often found in UV landscape scenes.

U330
When not stacked with an IR-blocker, the IR takes over in this dual bandpass filter.
The foto was white balanced on the clouds. Well, more or less.

RG9 and U330 comparison
Repeat of the preceding fotos because I was amused that the blue and green seem to reverse with these two.

I love the RG9/U-330 comparison at the end especially.
