Troy, it is a graduated density filter, darker in part of the filter and clear elsewhere. The same effect is accomplished by two separate exposures and then blending in software. The filter allows one to do it in a single exposure, for compositions where the transition line in the filter matches the scene - if you have a horizontal visible horizon, for example, then you can separate sky from everything else. If your horizon is not horizontal, say in the mountains, or due to trees or buildings sticking up into the sky, then the graduated filter is difficult to use.

That's cheating, and cheaters suck.

Mr. Gunnoe has done it.

I don't think it is cheating if you cop to it in the caption - he did.

Yes, they are very cool but somewhat pricey.

That is next on my bucket list.

This was done by Ken Szok with a graduated density filter and it looks great.

I may as well add my shot of the shredder shot using my graduated neutral density filter to make a better comparison.

The sunset is really what I was comparing.

You showed me that image in the camera and I was going for a silhouette, rather than having the dirt in the picture.

Is there any advantage in the gradient filter over two exposures and tone mapping?

As for combining images to get a properly exposed moon, isn't that the same, really, as combining images for tone mapping / HDR, so nothing that needs copping to?

I think the filter is the better way to do it, because you can always tone map that RAW file as well.

My program will will not selectively map only certain parts of the image, it is all or nothing.

Even combining two images, I think you have more control with the filter.

Course the person to ask is Ken because he has been doing this stuff for about half a year that I know of.

And, you can always do what Mr. Gunnoe did (as I remember) and that was move the moon from one exposure to another like this.

I taught Mr. Gunnoe alot of things, but that was a nasty habit he picked up from someone else.

I know you're being facetious, but in response to Troy, there is nothing wrong with combining two images to get a better exposure for the moon. It's no different from using the same practice to get properly exposed number boards. But of course, it's certainly different from cloning a different locomotive into a scene, or a misplaced reflection on the water.

Tis a better train photo than a moon photo, with that cookie cutter execution on the moon

Still worth every penny.

I think the version for a desktop is still free, btw.

I don't disagree Mitch. It looks pretty in-depth. I will probably take the plunge because a lot of the shots we take are a one time only opportunity.

I believe they've always charged for the smart phone app, as I checked three years ago and again last year. However, it's free to use on the computer. Now if only there were a legitimate suncalc app (I don't believe cuncalc is legitimate anyway due to its use of google maps, probably without permission).

Late to the discussion: Sorry, but it's not good at all. I would let this go and move on to something else.
