Default Corner market at Night using Photomatix

I combines 5 shots for this. I varied the F stop which is probably the wrong way but changing the ISO without moving the camera was a problem even on the tripod. Suggestions?

You should have only adjusted your shutter speed. Leave the aperture alone as well as ISO. Your image is too contrasy -- blacks too black and whites too white. Its odd though that your image is as sharp as it is having moved your aperture.

I haven't done a true HDR but I believe the procedure is to take 1 shot each at -2 EV, 0 EV and +2 EV the combine them using photo software. You can take more than 3 shots but I believe the minimum is 3.

I have done HDRs and the number of shots you take depends entirely on the range of light in the scene. It just happens that most mid range DSLRs only offer 3 shots as automatic exposure bracketing.

While Im here I just want to say Caryl that the colors in your shot are really good. This is a terrific picture considering how you did it or perhaps in spite of how you did it.

Thank you Bynx and Debbie. I think Debbie is right that you keep changing the EV. That way you get the detail in the whites and the darks. I need practice.

Yes the EV is changed by changing the Shutter speed. Why is this hard to grasp? Each click of the little wheel that changes the shutter speed is equivalent to 1/3 fstop so 3 clicks is 1fstp. Going to the left (on a Nikon) means +1EV, 3 clicks to the right equals -1EV. So if the scene requires 5 shots, then from your initial setup for the scene (0EV) click the shutter wheel 6 times to the right. If there are no blinkies in the highlights then take your shot. Then just 3 clicks to the left for each shot until you have some details in the shadows. This is the manual method I highly recommend for doing any number of shots required by the dynamic range in any situation.
