Default Re: Mental Ray Exposure Modifier

yep i'm with you now, i guess i've been doing that anyway, i've never really setup multiple cameras in one scene (camera in each room)

i usually just setup my light and position it where i want, and then adjust my exposure until the light levels look right.

i guess this is what you are doing just in the same scene.

i have one more question (well probably more than one - but we'll get to them later )

i have been using my digital camera to help me when it comes to exposure, it has a lot of built in presets for different scenarios, eg, moving water, sports, day, night, portrait, fireworks etc.

i was switching between the different presets to help me get exposure right, but when i check the settings on each one, the f-stop seems to be set at 2.8 regardless of which setting i choose, it only seems to be the ISO and shutter speed changing for each preset??

surely the f-stop will change aswell?????

but then again i have heard that i can leave the shutter and ISO at the same value and then just alter the f-stop????

and then i've heard i can adjust all three??

once again i'm confused

with regards to my digital camera, the setting of f2.8 means my aperture is open quite wide therefore letting a lot of light in. but i also read that the lower the f-stop number then the blurrier the image will be, unless compensated for with the other values?
