Process Tab: Size settings

What do the Width and Height settings do in the Process Tab? I'v got a bit confused because when I use the crop tool it doesn't do what I expect!

So, if I don't crop an image those two boxes will give the same dimensions as the sensor. When I crop using say, and A4 crop they don't necesarily correspond with the A4 dimensions.

On top of all that, I am subject to the \"lost pixels\" bug on my cameras and that is reflected in the Width Height settings.

Somehow in my head, I can't quite make the links between original image size, processed size and the crop tool.

If anyone can just start me off here....

Regards

Martin

  martcol,
  
  I'll give this a shot and hope I can clarify for you.
  
  The dimensions at Process Tab are for setting output Size. You will notice (PRO only) if you enlarge the dimensions the %Scaling will go above 100% and will be interpolating the image to get to the larger size. Maximum interpolation is %250. You will also notice that this is fixed in regards to the CCD size. If you check the Width box, then this dimension becomes locked. An example here is 4x6 output to a proof printer in your studio. If this is set, all your image output will be 4x6s And of course the Resolution setting has an effect on the image output as well.
  
  The Crop Tool establishes a crop ratio for your image, i.e. 8x10 is a ratio of .8 and so is 11.65 x 9.33 so picking a crop ratio of 8x10 may or may not be an 8x10 processed dimension. You also have the choice of Unconstrained for an arbitrary ratio.
  
  So if I have not confused you more, to summarize...
  [list=]Output at 100% will get you your full image file or As Is.
  Setting a dimesion, you get full image but at a set HxW
  Cropping establishes a ratio for the image and size can vary[/list]
  
  Cheers,
