Nice car. Great pics. I love the way the colors contrast in HDR.

You're car is freaking gorgeous.

I love HDR and what a great car to try it out on!, Beautiful!,

Nice! I came in here expecting to see some ****ty way over done HDR from some noob.

Well done, sir.

Also, that is most definitely Madison County HS

I'm a little confused. Wouldn't the dark areas yield the SLOWEST shutter speed?

No, when the shutter is left open, it tends to overexpose, much like leaving your eyes open looking at bright lights. Fast shutter speeds will cause a dark, underexposed image. Give it a shot, HDR this way, makes for a more natural, human eye-like photo, as opposed to the hyper-real stuff we see on the web.

The spot meter expects that which you point will be of 18% reflectance, like mid-tone grey, or a medium blue sky (excellent to meter off, by the way). I didn't see many complete black areas in any of the photos, so the range would be very nice with 5-9 shots, 1 stop apart.

I've got a recent sample from our backyard before the landscaping, where I have a very bright area (white garage) and a very dark area (corner fence). If I expose the garage, I have complete black for the corner, and the reverse occurs as well, I expose for the dark corner, and I'm left with a blown garage. I can post if you like, but there is no mustang in the photo (yet).

Now I'm more confused. I'm not saying you're wrong, but what you describe is counter-intuitive. My understanding of HDR is that it solves the following problem: if you photograph a scene with both highlights and lowlights, you can't expose properly for both. Either you'll blow out the highlights or lose detail in the shadows. HDR lets you expose properly for highlights (i.e. short exposure) and shadow (i.e. long exposure) and combine the results in post processing. If you point your spot meter at a shadow area, it should indicate a longer exposure. How are you preserving shadow detail with short exposure of lowlights?

HDR was designed to solve the sensor limitation problem. Sorry for the confusion, it can be confusing, and this is why so many images are full of noise, they have data loss in the shadow areas. Exposing for the shadow detail retains that data in one image, taking subsequent exposures, working your way towards the exposure that retains highlight detail will produce several images, the higher the contrast, the more images you may require. Simply taking 3 bracketed shots and hoping you have the histogram covered adequately, doesn't usually work. You are correct, you cannot expose for both in one image, you must take several, and they re blended via software. HDR is impossible with a single image. HDR is not an exposure technique, but a blending technique.

I'm not able to upload into this area, but I have a series of 9 shots to blend, these are the following:

Shot Preserved Shadow detail: 24mm f/8 for 1/20s expoure
Shot Preserved Highlight detail: 24mm f/8 for 1/1250s exposure
Shot in the middle: 24mm f/8 for 1/200s exposure

The blended imaged used 9 shots, all a stop apart in between the shadow shot, and the highlight shot, and produced an image with nothing blown and full detail, zero noise. I'll see if I can get these up on my picasa and you can view the series up to the final.
