    So I just received a D40x as a med school grad gift and love this thing and am trying to get the basics down. My question is regarding flash vs ambient light. How do you make the decision in a moderately lighted area to either change the shutter speed to get more ambient light or use a flash, whats the decision making process. Thanks for the help!:bowdown:

    When the shutter speed would be below a 1:1-1.5 ratio with the focal length of your lens if you're hand held. If I were shooting at 50mm I would want the shutter speed to be no less than 1/50-100, erring on the faster side (faster the better) for movement, so you don't get camera shake. Or, if the ambient light wouldn't provide the desired effect.

    But whatever you do, don't use the onboard flash unless it's diffused and the direct flash look is what you're going for. A better option 99.9% of the time is getting an external flash and putting it off camera with modifiers. If you can't do that, bouncing it off of a good ceiling is better that direct flash.

    Off camera flash > Bounce > Dogshit > Direct flash

    thanks

    Thanks for the help! Last night I took multiples of the same shot adjusting the aperture, iso, speed and was finally able to appreciate how each setting individually altered the image.

    Flash exposure = aperture, flash-to-subject distance, and ISO. Shutter speed has no affect on flash exposure. Use it to control the amount of ambient light.

    Direct flash can be better than no flash in plenty of situations though. Not really for indoor shooting but more of a fill light to light up their eyes if you only have the sun in a sub optimal position. Just make sure to dial it down to -.7 or -1 flash strength though.

    I'm the same way. I use available light until I absolutely have to use a flash.

    onboard flash is useful for outdoor fill flash.

    Thanks, med school wasn't that bad, its residency that seems more concerning, I'll post up some pictures later that I took in Chi near the lake to get a better idea of what settings to change to optimize my pictures.
