There are times where photos are needed right after an event. Some higher-end cameras allow the photographers to select the images they wish to submit as they are shooting. As such, this helps speed up the workflow. Another big time saver is the use of a grey card. It helps make quick adjustments to the white balance (colour) for each image before converting it to jpeg in post. For jpeg shooters, some cameras will allow you to create custom white balance profiles before the event. Doing so allows the photographer to swap between profiles during an event quickly.
Unleashing Innovation 2013 was an event organized by The Wall Street Journal at Capella Hotel Singapore. The event was three days long, and the client needed the photos at the end of each day. It was a challenge as the event stretched from morning till night. The client provided hotel rooms to the crew to ensure we could process the photos as quickly as possible while ensuring we had enough rest for the following day.
