don't know too much about HDR but i think you would get a better perspective of how it worked if you took shots of the whole car

what program are you using and how many photos are you using? it looks a little... dark to me, and not too HDR-ish, but keeping it subtle is never a bad thing.

that probably wont work for getting 3 different exposures... when you change the iso the camera probably adjusts the exposure so you're getting about the same time each time. you need a photo thats intentionally light and a photo thats intentionally dark, as well as one thats just right. but you can always do hdr with a single photo if its a raw file, not sure if your point and shoot does that.
i think you have to convert to hdr and then tone map, are you doing both?

Using photoshop to make one dark and one lighter isn't the point.

The point is you use the camera and take and overexposed, an underexposed and a just right. That why the photo catches different shadows and what not..

whenyou merge the three you're gettin the best of every world.....try againnnnnn

yeah its got to be 3 seperate photos... or you have to shoot in RAW. if you dont understand what that is then look it up and find out if your camera can do it. the whole thing is really based around RAW photos but i believe it can be fudged to use jpg as well.

looks better but its still not really doing it. the ideal is to take one photo exposed correctly, one two stops darker and one two stops lighter, and combine the three to have one image containing all dimensions. one has all the mid tones, one, the darker areas(lighter exposure), and one the lighter areas(darker exposure) to have one picture thats most true to what you see with your eyes.

ex:

ORIGINAL - Proper Exposure:

HDR - 3 exposures combined

see how the dark areas are now visible after combining the different exposures?

if you're camera has exposure bracketing thats the easiest way to go about it, take a look in your manual. it will automatically bracket the exposures so you can get the correct images.
