The mark consists of the Comparative Slider. The Comparative Slider is a line with two moveable shapes on it. The shapes can be moved at specific intervals which may or may not be designated with visible notches. The intervals represent separate points in a comparative process. For example, they can be chronological points in time. There is a corresponding piece of media that is linked to the specific notch. As the shape is moved along the line past the multiple notches - the media above changes and is able to be compared to the media beside it. For the purposes of this example of The Slider the media is stored in the captureproof platform database, the media will show up when the shape is moved to the relevant notch on the line. There are always two or more shapes positioned on the notched line at any given time, meaning two or more images from the platform are recalled and available to be viewed side by side.
