Right, but easier to check LCD for exposure and color if WB is correct

I presume they are using flash heads.
You can control flash light either by decreasing flash power, changing ISO or aperture, shutter will hardly do anything if flash is the predominant light source.
I doubt they will let you tamper with flash heads so your only options are aperture and ISO.
Start with f/8 and ISO 200 and change as needed, you can leave shutter speed at 1/60 and WB to flash of course (WB does not matter really if you are shooting NEF though).

I don't understand the Original post. Are you saying that you give your camera to a Disney employee and they are taking the picture for you? So are they just putting a pocket wizard (wireless flash trigger) on your hot shoe (where you normally put the flash on top of your camera) and then taking your picture?

What mode or setting are THEY using? Full auto?

OK a few things:

Your D90 can max sync with strobes at 1/160s, flash triggered or wireless remote triggered, so start with that speed

Start with ISO 200, only increase if more power is needed, do not use auto,

Start with F8 and check histogram, LCD for exposure, then adjust aperture to fine tune exposure

Set WB to flash

Remember using strobes everything is set manual, the camera can not meter anything

Have fun

I must have been writing past my bedtime last night. Setting your camera to Aperture priority won't help if the camera's not metering lights.

Do what spraynpray or heartyfisher suggested. Either method will work.

If I were setting up dozens of Nikon booths I would be saving some money and not getting CLS but standard triggers. so manually set Aperture , shutter and ISO. I would go with ISO 200, 125 Shutter and F8 to start with then change the aperture to suit depending on the histogram.

Why not throw on a couple of stops of under exposure compensation and check again?

You're quite welcome. Actually, after thinking about this a little, if #1 and #2 don't work, maybe you want to ask what ISO, Shutter Speed and Aperture combination the guys at each booth are using with their cameras. Then, dial those same settings into your camera. That might be best starting point. Please let me know how this all works out.

Thanks for the help!

Oh, if you have to resort to #3, above, then take your camera out of Auto ISO and put it at ISO 200.

I'm not really sure how your camera is metering with the lights you're using. Someone here might be able to give you some BETTER advice but, since it sounds like you might need some FAST advice to get some photos now, try this:

1. Ask one of the photographers how Nikons meter with their system. If they know, great. If not, go to 2.
2. Stick your camera on Auto. If the photos come out well, then make due with the Auto setting. If they do not come out well, then your camera is not metering with their lighting system. Go to 3.
3. Put camera back in Aperture priority. Have them take a quick series of shots, as follows: start at aperture 3.5 or so and stop down with each shot after in the series until you find the right exposure. Should only take a minute or two and you may be able to use the same setting at each booth, assuming ambient light doesn't change much and they use the same setup at each booth.

Not familiar with the CLS but they put a wireless device in my hot shoe

First, check a couple of the overexposed photographs that you already captured--on your LCD screen--and see what ISO your camera selected. If it selected ISO 200, then try stopping down. It may be that the lights are too bright for ISO 200 and f/2.8. Take a shot at f/8 and see what happens.

Second, how is your camera triggering their lighting? Are they using the Nikon CLS system?

I have a question. I am currently at Disney World and they have little photo places set up all over and are using Nikon cameras. They will use mine so I have the pictures but when they use it with their lighting the photo is coming out way over exposed? Can you help with this? I have a D90 and using a 24-70 2.8 lens. I have the WB on Auto the f. at 2.8 and the ISO on auto using aperture priority.
