Photoshop help – cropping to an exact size?

Hello,

I need some help on how I can make a constrained 1024x768 crop from a 3906x2592 full frame original.

My problem:
  • I open a 3906x2592 full frame original and display it at 33% to fit the screen so I can view the full frame.
  • The Image Size panel shows it as a 3906x2592 at 240 pixels/inch object.
  • I then set the crop area to 1024x768 at 72 pixels/inch.
  • I then drag the crop frame, but it does not constrain the crop area to 1024x768.
  • That is, it can be dragged to cover all, or very little, of the 3906x2592 full frame??

Help!
After I have opened the original to “fit screen” so I can see the full area, I would be very grateful if someone could explain to me how to:
  • Create a crop area 1024x768 that constrains the crop to 1024x768.
  • Drag it out so that when the crop frame reaches the 1024x768 size, it constrains me from dragging beyond this.
  • Move the constrained 1024x768 crop frame around within the full frame to select the precise 1024x768 pixels.
  • Make the crop!
I’m probably missing something extremely simple, but I just cannot figure out to perform what I think should be a very basic crop operation!

Thanks!

Dennis
