I have been reading Bryan Peterson's book "Understanding Exposure" in which he talks about "Creative Exposures". He first focuses, chooses an aperture and then adjusts the shutter speed until the correct exposure is indicated in the viewfinder. Could anyone please explain how to do this on my D200.
You can use priority A, f/8-f/11 (who care sharp images), f/3.5-f/5.6 (portrait), f/16-f/22 (landscape), ISO 100 (for less noise)and a calculated velocity by the camera, not below 1/30, for not to use tripod.

Set your aperture, and while watching the exposure indicator at the bottom of the viewfinder, keep turning the shutter speed dial until the exposure variance is as close to center as possible.
Thank you for your advice which was very helpful.
I really want to master the manual exposures technique which
will provide a good basis for understanding and getting the
best from the other exposure methods.

Actually once you get the hang of using manual exposure, it provides a powerful tool for making most adjustments, assuming you have measured the light falling on the elements in your scene.
Interesting thing about Bryan Peterson, I think he wrote this book when he was first starting with digital and did not really have a trust of using Aperture or Shutter modes. I think in later stuff he actually realized that those modes really do great creative exposures but usually easier and faster than the fully manual approach.

Thanks for your comments and I agree with you on your view of manual exposure.
Like you, I had the same feeling that Bryan Peterson was in the transitional stage of film to digital when he wrote the book. He stresses the importance of the "meat & potatos" concept of getting manual exposure under your belt so that it will provide a good foundation in your understanding of exposure in total.
Hello Chad, Yes, the book goes into great detail on the subject of your question and there is wealth of information on everything connected with exposure. It teaches you to walk before you try to run. I strongly recommend it.
