Who out there has accidentally switched their camera into bracketing mode?
This is a hiccup we've see happen more times than we’d like, and it can lead to some major headaches. A job can be going along smoothly, exposures are perfect, when out of nowhere—boom—bracketing mode was turned on, causing a photographer's exposures to shift from frame-to-frame. Yikes!
Rest assured, our color technicians are very skilled at spotting bracketing mode and smoothing out inconsistencies in exposures. But even with all their #skills, you might still be able to catch some slight differences in your final images.
Bracketing mode is designed to take 3 shots back-to-back of the same scene at different exposures, varying in increments from ⅓ stop to 3 stops, depending on your camera. This can be handy when you are unsure of what the proper exposure is for a given scene. For these circumstances, bracketing mode acts as a safety net and can be handy. But when bracketing mode is accidentally turned on, it can be a nuisance.
📷 The first exposure will be made at the shutter speed you set (N).
📷 The second exposure will be made at a decreased Exposure Value (-N).
📷 The third will be made at an increased Exposure Value (+N).
Check out this example, shot by Christine Pienaar:
Notice how Chrstine's Exposure Reference Sheet shows slight shifts in density from frame-to-frame? This represents shifts in exposure. When exposures shift in a repeating pattern, like they do here, it is a clue bracketing mode was turned on.
We can also verify bracketing mode is on by checking the exposure data. Christine’s roll here is as follows:
Frame 1: 1/60 0.0 EV
Frame 2: 1/125 -1.0 EV
Frame 3: 1/30 +1.0EV
This not only tells us bracketing mode is on, but it also tells us the bracketing is set to 1 stop increments. Our Exposure Reference Sheets allow you to identify this as soon as you see your scans, so it can be turned off prior to your next shoot. And don’t worry, we’ll be sure to notify you via email or phone when we see it, too!
*Keep in mind: if you change your shutter at any point while in bracketing mode, the pattern in exposures will NOT be consistent.
These scans are from Christine’s roll above. Notice how despite the shifts in exposure, our expert color technicians were able to create consistent scans. Consistency is, in part, dependent on the bracketing amount.
Consult your manual and learn how to turn it on/off before you next shoot, just in case!
