Indesign Crop Mark and nudge

To crop or straighten images in Camera Raw
In the Camera Raw dialog box, select the Crop tool or Straighten tool .
(Optional) If you want the crop area constrained to specific proportions, click the Crop tool icon and choose a proportion from the pop‑up menu. Choosing Custom opens the Custom Crop dialog box, where you can specify the proportions or the dimensions of the crop. Click OK.
Do one of the following:
To crop the image, drag the Crop tool over the image.
To straighten the image, drag the Straighten tool in the preview image to establish what’s horizontal or vertical.
(Optional) To adjust the crop area, do one of the following:
To scale or rotate the crop area, drag just outside the bounding box handles.
To move the crop area, click in the bounding box and drag.
If you selected several images in the Camera Raw dialog box, they are all cropped to the same size, with the crop applied in the same position.
Note: To cancel the crop operation, press Esc with the Crop tool selected or click the Crop tool and choose Clear Crop from the pop‑up menu. To cancel the crop and close the Camera Raw dialog box without processing the camera raw image file, click the Cancel button or deselect the Crop tool and press Esc.
Click Open, Done, or Save to apply the crop and process the camera raw image file.
