To start the measurement, select a photo. We recommend that you use the Photo Import Wizard because the photo has to meet certain requirements.

The measurement is taken by selecting the parameter to be measured. Once you select it, an arrow appears on the photo. You should position this arrow on the photo in the same way as it is shown on the panel to the left.

You can move and resize the arrow. Use the mouse to do it.
While taking the measurements, you can scale the image and move it. Use the corresponding menu item or toolbar icon.

Please remember that the beauty rank error is related to errors during the measurement. That is why it is recommended to use a photo meeting the requirements and precisely specify the points.
