Tether Display is an application for convenient viewing of photos during tethering. Thanks to it, you can easily display the current photo while shooting. The last few photos are shown on a different monitor or device. It enables to viewing and rating photos by people involved in session or by your client on other devices in local network (e.g. connected to the same Wi-Fi), and even share the preview over the Internet.
Tether Display is built from two modules: application server and web application (webpage) for viewing photos.
The application server is part of the program that reads the photos from the photos directory and makes them available through the web application for viewing that can be opened in web browser.
Photo preview can be viewed on any device in the local network or, depending on the settings, even via the Internet.
The application during work generates temporary image files in various resolutions suitable for devices on which currently are browsed. For example, for 500 photos viewed on two devices (computer and tablet) the required free space on the disk is 4GB.

Below are descriptions of particular types of views.
This view displays a single photo with the necessary details:
By default, it is displayed in the upper left corner. You can change its position using the button or hide it by clicking on . The histogram can be displayed in one of three variants (set in the application settings):
Overexposed parts of image
By default, the application highlights the overexposed parts of the image in red.
You can disable this function by clicking or using the O keyboard shortcut. You can change the overexposed threshold in the application settings.
Details about the photo are displayed at the very bottom. From the left: focal length, shutter speed, aperture value, ISO value, resolution, name of the photo, rating that you can change by clicking on the stars, number of the active photo and the number of all images.
This view displays several photos arranged side by side.
Depending on the settings that you can change in the application settings or in the view settings, this view can display the most recent photo on the right or left side of the screen and arrange it from left to right or vice versa.
In this view, photos are displayed as thumbnails.
In the settings you can change their size and ratio of the sides to better match the type of photos. In addition, you can change the size of the thumbnails using the buttons in the lower left corner of the screen.
Clicking on the selected thumbnail will change the view to single photo. In the case of another tab on this device, the single photo or multiple photos view is open, then the photo will be displayed in this view.
Each view can be configured to display the latest photo as active or one in relation to the newest one (offset), e.g. the penultimate photo.
This feature is useful when using multiple monitors or even devices. For example, one monitor displays single photo view, and second monitor multiple photoss view. The new photo will be displayed in the single photo view on first monitor, and in the multiple photos on second monitor active will be the last but one. This way, monitors or devices do not display the same image twice.
Using these options, you can configure the preview in an unlimited number of ways.
Examples of use:
The monitor on the right displays the current photo and the monitor on the left 3 previous (offset -1).
The monitor on the left displays the current photo, the monitor on the right the last but one (offset -1), and the tablet displays the multiple photos view with offset -2 set so that it displays subsequent photos.
The left monitor displays single photo view and right monitor thumbnails view.

Path to photos directory - directory path from which Tether Display will lad photos.
The application only reads files in JPG format. You can enter any directory that contains photos in JPG format and browse photos using Tether Display (photos are sorted from oldest to newest)
Sharpness level - additional sharpening that will be applied to the displayed photos.
As the author of the application and a beauty photographer, I prefer sharpening photos while watching them when they are unretouched. You can turn off sharpening by entering the value 0 in this field.
Clear photo cache - the application during work generates temporary image files in various resolutions suitable for devices on which currently are browsed. For example, for 500 photos (from camera with 26mpx) viewed on two devices (computer and tablet) the required free space on the disk is 4GB. These files are automatically deleted when Path to photos directory is changed to another one or you can clear them at any time by clicking this button.
