Almacene instantáneas de desarrollo y compárelas con la edición actual.
A snapshot is a stored bitmap of the center image in the darkroom view. Snapshots can be taken at any point in the development process and later overlaid onto the current center view. This allows you to undertake a side by side comparison (by default left=snapshot, right=active edit) while you are tuning parameters of a module. This can also be combined with the history stack module to compare a snapshot against different stages of development.
Para tomar una instantánea, haga clic en el botón tomar instantánea. Sobre el botón, verá una lista de las instantáneas que se tomaron para esta sesión de edición. El nombre de cada instantánea refleja el nombre del módulo seleccionado en la pila de historial y su posición en el momento en que se tomó la instantánea.
Click on the name of a snapshot to show it – this enables a split view between the saved snapshot image and the current state of the processed image. You can control the position of the split-line by clicking and dragging the line with your mouse. If you hover over the split-line with your mouse, a small rotation icon will appear on the center of the line. Click this icon to change between vertical and horizontal split view – the positions of the snapshot and current image will be rotated anti-clockwise allowing you to choose whether they appear to the top, bottom, left or right of the screen.
En todo momento, se muestra una flecha que contiene la letra “S” para indicar qué lado de la imagen es la instantánea (Snapshot) y cuál es la edición actual.
Click on the name of the snapshot again to disable the overlay and return to your editing session. Click the module’s reset button to remove all existing snapshots.
Note: Snapshots are retained for the duration of your darktable session. This means that you can also use snapshots to compare with a duplicate edit of the same image. Just navigate to that image and enable the snapshot view as normal.
