Lightroom Cropping without resizing?

Can you tell me if in Lightroom 2 There is a way to crop photos without resizing or changing pixels? If I have a full sized shot that is 2832 x 4256 and do an original crop just to bring something in closer or change the way it is framed why do the pixels have to change? Is there anyway to avoid that or is that just a pipe dream and I have to work much harder to get the composition right in the camera:D

    When you crop you are physically removing pixels to create the new composition. The only way to then get a larger image size would be to uprez the cropped image with a program like genuine fractals. If you started the process with more pixels (Like a D3x) you would have more flexibility to crop, but getting it right in camera is preferred.

    Sandy,
    Sounds like you perceive a need for preserving as many pixels as possible. What's driving this need? Do you have a requirement for printing at a specific "large" size?

    My impression of LR crop was it didn't mess with the pixels, it just tosses them. If you print the result to some specific size/dpi, then that's where the resize comes into play. Am I missing something here?

    Lighroom never tosses pixels!!

    But if you export an image from Lightroom as a jpg, and it has been cropped significantly from the original file, the jpg then subsequently exhibited in Lightroom will only possess the pixels remaining in the cropped file.

    To get all the pixels in the original file, just go back to the original file, prior to the editing done to it. In the Develop panel, go the the History column in the panel to the left of the main image, and slide the history slider back to Import, hit Command ( ctrl in Windows )+' and you will have a new original file unaltered ready to re-edit as desired, and your original file is still unchanged with your primary edits still available.

    You cannot crop an image down to 10% of its original size and still retain the same number of original pixels in the cropped image. Not happening.

    Cropping is independent of resolution in LR since you’re just specifying metadata instructions. Only when you export (or open in Photoshop) are those pixels you cropped out ‘removed’ and in export, you control the output resolution in your export presets.

    Maybe she's confused by the fact that when you crop in LR it automatically zooms the image to fill your display area back up. So maybe the OP interprets that as cropping and resizing?
