I'd like to take some creative photos of my Ambulance at night with my lightbar activated. We use LED strobes. What settings would you recommend?

HDR otherwise the LEDs may underexpose everything else

If you expose specifically for the light bar, it will severely underexpose everything else so you need to shoot a series of bracketed exposures from a point at which the lights are correct up to whatever EV level gives you a good exposure on the rig itself.
You then blend the images in post processing using only the parts of each shot that are properly exposed. Put your camera on a tripod so all the shots remain registered (aligned the same), use the self timer so you don't have to touch the camera too much, choose an aperture (f/stop) that will give you sufficient depth of field to keep the entire truck in focus and walk your shutter speed up from relatively slow (exposing the truck) to relatively fast (capturing the lights at a good level.) You'll probably have to do several shots at the last setting so you capture the lights the way you want them.

I finally took my camera to work because the last few shifts have been really slow. So, of course, I was ran to death today. I only had time to take 2 very crappy photos before I got sent on another run. So here are my very first shots:
![]() ![]() I am going to build on this and I can't wait to show you guys something decent. You see that violet light shooting out of the top of the unit? What is that called and how do I compensate for it?

Filter on your lens?
If so, remove it...
