At most gigs, I am usually working with one or more photographers. We each have one to two camera bodies shooting throughout, each with their own file names. At the end of a wedding, for example, we often have three to five THOUSAND photos to deal with. I know it sounds like an excessive amount, but think of all the portions of a typical wedding or event. Then consider that for every photo, such as a family formal, you have to take about five shots in order ensure none of the subjects are blinking or looking away in one of them. All of these photos and file names can lead to a real organizational mess come post production time.
The simplest remedy for this is to sync all the shooters’ cameras to the exact same time, down to the second. Then, once the photos are imported into an editing program, choose to sort the photos by the time. Bam, they are all in sequential order, allowing you to choose your favorite angles with no jumping through scattered files. Some of you are likely doing this already, but you would be amazed how many photographers skip this step. I think part of it is that old habits die hard when it comes to file naming, importing and organization. Handling files can be an anxious place where caution meets superstition and paranoia. “Rule # 1: Don’t loose the files.”
Anyway, so all the photags at a gig can gather together in a huddle and sync up to a specific time by setting their camera clocks on the count of three or something, but this is a pain and often everyone starts the day in different places. An easy solution is to sync to a common time that is consistent and displays down to the second. One we use in a jam is the iPhone clock, since those are all standardized and always handy. Another option is to sync to the official National Institute of Standards and Times website the morning of the gig. You can’t get more accurate than that. If you aren’t sure how to set the time and date on your camera, here are the product manual links for Nikon and Canon.
