The wedding is over, and now the real work begins.
If you use 2 or 3 (or 4) camera bodies at an event, your files names can be all over the board. If the clocks on your cameras are not synchronized, images will not mesh and your timeline will display incorrectly.
In order to avoid confusion both in the way you view your work, and the way the client views the images, its important to merge all images into one timeline, and to have the numbering sequence begin at 1 and proceed upward without a break in the numbering system. (If you’ve ever shown a client a sequence of images with a number missing, you know the first thing they ask is “where is the missing image”. To avoid that question, renumbering is the way to go.)
It’s also important to give your images an easy numbering system: 546.jpg and not IMG_546.jpg. The easier you make it from the beginning, the easier the entire process will be.
