Using GIMP: Correcting and Touching Up Your Images - GIMP 2.6 for Photographers: Image Editing with Open Source Software - page 75

• Transform lets you crop and rotate the image and correct distortion.
In addition, you can correct chromatic aberration and the effects of
vignetting and resize the image to your preference.
• Metadata contains EXIF and IPTC information.
• The buttons on bottom of the preview window are as follows:
• Save Image : After editing, you can save the image in the TIFF and PNG
formats with either 8 or 16 bits per channel. You can also save the image
in JPEG with 8 bits per channel.
• Put to queue: When this button is clicked, the open image is sent to the
queue of images waiting to be rendered.
• Send to editor : This button opens your image in the editor of your
choice. If GIMP is installed then you will find GIMP as the default setting.
As I said, RawTherapee is a compact autonomous program for the most
common editing steps.

• Change its size on the screen (zoom in or out).
• Set the size and resolution.
• Save it in a high quality format.
• Prepare it for printing.
