Light Boxes
In photography, a lightbox has several applications. One is a container with several lightbulbs and a pane of frosted glass on the top. It is used by photography professionals viewing translucent films, such as slides. This device was originally used to sort photographic plates with ease. It is also used by visual artists for photo-referencing.
Generally, a lightbox uses light similar to daylight (5,000–6,000 kelvins (K)), has uniform light strength on the glass pane, and has adequate light strength (in order to not strain the vision).
Another use of the term "lightbox" is for the fabric reflectors that attach to studio lighting via a connector to create soft lighting by diffusing the strobe flash. They generally come in various rectangle shapes, although recently they are being manufactured in an octagon shape. Interior reflectors can be white, silver or gold to alter the temperature of light. Baffling inserts are also available.
A lightbox may also refer to:
- a folder used on stock photography[1][2][3] to allow a user to organize digital photos. Photos can be assigned to a viewable lightbox folder by subject, for later convenience, or used to compile unrelated photos for a specific project layout. Lightboxes also allow graphic designers to show clients options for a project in one simple uncluttered folder.
- a device similar to the photography lightbox, used for viewing x-rays.
- the card-reader near the door in a hotel room, used as the main electrics switch.
In the science field, lightboxes are often used for looking at bacterial growth and allow better visualization for PCR plates.
In recent years smaller lightboxes have become more popular due to their transportability.

Billboard
A billboard (archaically a "hoarding" in the UK) is a large outdoor advertising structure (a billing board), typically found in high traffic areas such as alongside busy roads. Billboards present large advertisements to passing pedestrians and drivers. Typically showing large, ostensibly witty slogans, and distinctive visuals, billboards are highly visible in the top designated market areas. Bulletins are the largest, most impactful standard-size billboards. Located primarily on major highways, expressways or principal arterials, they command high-density consumer exposure (mostly to vehicular traffic). Bulletins afford greatest visibility due not only to their size, but because they allow creative "customizing" through extensions and embellishments.
