Unlike other software, Cropping and Horizon are two separate functions of PhotoLab. The independent application of each of its corrections allows to gain in precision.
– Draw a frame along the diagonal by holding the Left click
– Press ENTER to exit the tool

Click to enlarge – Alt+ < to return

Description of the 4 states

1- By default this function keeps the proportions, the initial ratio, of the photo
– Choose a different ratio OR
Choose from the list or enter any value, numeric or ratio eg: “1.333” or “6.5 / 4”

The 7/5 ratio corresponds to the ISO A format (A4,…).


PhotoLab reports live the pixel dimensions of the cropped image. It is not possible to enter values.
The metadata window always displays the size (in pixels) of the original photo. PhotoLab only resizes the image when exporting. It is at this moment that the output dimensions must be indicated.

See the

tutorial “Efficiency with PhotoLab – Export photos”


By default PhotoLab overlays a 3:2 grid for cropping according to the rule of thirds.


2- A combination of keys allows you to quickly switch to an unconstrained frame, there is no need to select the “unconstrained” option
– While holding down the CONTROL / SHIFT key
– Pull on one of the corners of the dotted frame OR
– Pull on a handle of the edges to limit the direction
– Release the press on the key

Unconstrained mode becomes permanent for this image.

When carrying out new operations on the frame of this image, it is no longer necessary to press the key.
– Hold down the SHIFT key (Windows and Mac) to modify the frame while preserving these new proportions

On wide-angle photos, PhotoLab recovers much more lateral information than other software and direct JPEGs (especially for photos taken with cameras applying digital corrections). The starting frame of the cropping function sometimes cuts off those gained pixels which can be valuable.
– Switch to “Unconstrained” mode to preview the gain
– Disable the “Keep aspect ratio” option, Distortion function of the “Geometry” palette, to recover the maximum area of ​​the image corrected for distortion



3- Swap the Landscape and Portrait orientations by selecting a vertex then cross the frame diagonally by holding the Left Click until you go past the opposite vertex

4- After the Horizon or Perspective corrections, restore the option “Auto based on perspective / horizon” to force the frame to occupy the maximum rectangular area
