HDR(High Dynamic Range) SHOT fail test.....

Original Picture

Try making HDR shot Nikon D50 using the following settings:

• Lowest ISO setting (200)
• Aperture Priority Mode (usually a big [A] on the wheel)
• 3 exposure settings
  
  
  • EV 0 for the first picture
  • EV -2 for the second picture
  • EV +2 for the third picture
  
  
  
  
  
  
  
  
  Is there any different? Using automate Photoshop CS3 HDR merge 16 bit channel.
