Qn3: if my picture taken is "xxxx" by "yyyy" pixel and i wana scale down to "yyy" by "xxx" pixel, how do i do this?


mmm... im just trying to help you, here.

Q1. Yup, you'll need to understand the "Masking". Once you know the masking techniques, it wont be hard for you to separate the bgk and your main subject, so that whatever adjustments you make would not affect other areas.

Q2. I dont really understand your question about duplication the image. What I understand is something like creating a duplicate layer...

Q3. If you're using Adobe Photoshop, go to Image -> Image Size... and change the numbers to the ones you desire.

Hope that helps.
