Taking pictures of your trade show display are important. Not only because it is nice to see the different places that the display has been and the events that you have participated in, but because it is also important to see the different ways that the display has been showcased. You can then go back and see what has worked best with your set up. Did the traffic with your trade show exhibit booth increase with certain set ups or did it decrease? What was the best display lighting? How did it look in a corner or on the end of an aisle? keeping track of these things through photographs can help you with future set ups. The other thing that it allows, is for you to be away and have another person set the trade show display without you being present. Perhaps your flight was delayed and you need to have someone else set up the booth. Sending them a picture on their cell phone can help them see how the display is to be set up. Taking pictures can be important. Tell your exhibit booth to strike a post next time it is in place.
