I'm out in the California Mojave desert, relatively new to digital and all but a stranger to my new D7100. It's an incredibly complex device.
I have it set to leave JPGs in slot A and RAW images in slot B, and to generate 5-exposure bracketed images at 1-stop intervals. Here's the thing: sometimes it does, sometimes it doesn't. I have no idea why.
The only thing that comes to mind is that I've set it to make no exposure when AF fails to find a focus point, but that as a cause makes no sense. My shots are tripod-taken landscapes.
Can you provide more detail of how you're using it? In single-release shutter mode, you will still have to depress the shutter button five times - the only time it will take more than one exposure with a single press in single-release mode is if you have activated HDR. If you're using Cl or Ch, then if you hold down the shutter release it should take five shots and stop.
I'm new to bracketing. I'm going to Europe and what to take the best shots I can. Should I set it to 3 or 5 and what increment is best ? I assume I'll be shooting mostly outside daytime with WB at either sun or cloudy and using it in A setting, 17-55 lens.
Trace, if you are using the ML-L3 remote for your images(mirror up remote release), it will not take a sequence with one push of the shutter release button. The D7100 is great for bracketing. I shoot in manual(focus and all settings) and use the MC-DC2 wired remote($25.00). I have the release mode dial set to CH. After composing the scene go to Live View, the mirror will go up and stay up until you exit Live View, I now zoom in to what I am going to focus on, focus, hold down the shutter release button on the cable release until the number of shots has been taken, it will stop automatically this way. Exit Live View. Remember to shut off bracketing as it doesn't leave bracketing mode even if you turn the camera off. This is especially true when shooting different scenes and taking test shots.
