Agreed with the Halo "effect" A few minutes in PS could probably take care of all that.
I'm right there with you on the experimenting with tone mapping, with these two particular images I uploaded I was really displeased with how flat and boring the images were. Combining three exposures together and tone mapping really solved that problem. Did I capture what I saw? No... I captured what I wanted to see, I suppose that may defeat the purpose of photography as a reproduction of reality but it certainly by my definition still allows it to be art.
I attached the originals to make my point!
From the originals it looks like a mid-day sun, bright and generally not the kind of light for dramatic landscapes, or photography in general...
In cases like this, definitely pushing the contrast while keeping the whites and blacks from clipping is going to add the drama to make them look much better. Ansel Adams (probably the original 'tone-mapper,') shot a lot of his famous pictures in the middle of the day, using red filters and both development techniques and printing techniques to extend the dynamic range of his black and white prints.
I tend to experiment with HDR methods with high contrast shots that just don't really work well normally, especially with digital cameras, because the shadows are just too dark, and the highlights are blown. And example for me would be a shot in the redwood forest with late afternoon sun streaming down through the canopy in a back-lit shot, like in a cathedral. In person this is a fantastic scene, but a straight-non HDR shot from a digital camera really is limiting. For me, the perfect HDR image would look much closer to what my eyes saw live and in person... both on a display monitor and printed. That's the goal for me, and it's not easy. One of the things I like about experimenting with it is that it makes me slow down, and plan a little more while shooting - the tripod effect.
I guess I'm going to have to buy my Photomatix license so I can get rid of those pesky watermarks...
Here are the first couple of images I tried Photomatix on, both were from three exposures 2-stops apart, -2, 0, +2. Anything moving, like water or leaves presents it's own problems...
