Trust me the 25w light made a huge impact... even back 10ft it made a huge difference. It was during sunset. So i just needed enough light to expose the faces.
I wish I could post pics of with the light and without. Makes me frustrated just comparing the two.
In the defense of the photog. We were very limited on time (I didn't even have the chance to set up any creative shots, and really neither did she).
I'm sure there wasn't a huge issue but it was just easier and faster to tell me to turn it off.

Higher ISO would actually INCREASE the depth of field for any given shutter speed - more sensitivity means smaller aperture means greater depth of field.

I hope not to be snarky but my point was a higher ISO setting would require less power out of the strobes therefore increasing the impact of ambient light.

Higher ISO does not increase or decrease the DOF, it mearly makes the camera more sensitive to light.

The aperature setting is the only way to change DOF.

I did write higher ISO with a large aperature.

I have more experience with the photography side, so I can't provide the perspective of a videograher, but there's SOME merit to the notion that a video light can impact the photography.

If the light isn't daylight balanced, it could cast a color on the pictures that will be unappealing. Most of the video lights I've researched are daylight balanced, and if that's the case with your light, it shouldn't effect the photographer in this regard.

If the flash is just being used for fill in a sunset scenario, perhaps the video light was powerful enough that it was effecting the "look" of the shot she was going for. Maybe you were casting light in an area where she wanted shadow, or you're throwing off her exposure because she's not using a powerful setting on the flash(es)... whatever.

Regardless of all the above, you're both there to get the job done, and if there's not enough time for both of you to do exactly what you want, then there needs to be a compromise. Maybe she doesn't get the EXACT shots she wanted and you don't get your ideal shots, but at least you both get the job done. Her job is no more important than yours, and vice versa. She has no right to tell you what you can and can't use to get your job done any more than you have a right to tell her she can't use a flash. Can't we all just get along? ;-)

Contextually MUCH more accurate, thanks for clarifying.
