Why is my far away background in focus even with a low aperture number? Awesome explanation as usual. Thank you. |

Why does EV increase as ISO increases? My assumptions were wrong and the way I was calculating EV was also wrong. Details are in the comments of the accepted answer below. Not sure if this question should be closed but it was certainly informative to me. Thanks, all. |

Why does EV increase as ISO increases? Ok. I am going to accept your answer and add a comment summarizing everything. Not sure if this question should be closed because the premise was off. Thanks so much for your help! |

Why does EV increase as ISO increases? I am sure you are right... The equation I got from Wikipedia was: upload.wikimedia.org/math/a/3/3/… I guess the plus sign should be a minus sign? |

Why does EV increase as ISO increases? The update to your answer has been very helpful. I just have one more question if you don't mind. These exposures have the same EV of 14.64: F/4, 1/100s, ISO 1600 and F/8, 1/100s, ISO 400 I don't understand that. I would expect the second exposure to be darker because the aperture is allowing less light in and the ISO setting is less sensitive. I just don't get it. Thanks for your patience. |

Why does EV increase as ISO increases? Ok, for your example, when I have: F/16, 1/100s, ISO 100, I get an EV of 14.6438561897747, which is what you got. But when I make a change from F/16 to F/18, the EV changes to 14.9837061926594. F/18 allows less light in than F/16, so the image will be darker, so why does the EV increase? If I change to F/8, allowing in more light, the EV is 12.6438561897747. I don't understand why the EV would become lower as I allow in more light. Does that make sense? Thanks for your help. |

Why does EV increase as ISO increases? I am sure it is something I am not understanding, but then why does EV go down as I increase shutter speed and decrease aperture? Don't those things increase brightness? |

accepted | When determining exposure, is ISO typically taken into consideration secondary to aperture and shutter speed or is it equally as important? |

When determining exposure, is ISO typically taken into consideration secondary to aperture and shutter speed or is it equally as important? Thanks for the response. You said: "For sports, I first set the ISO to the highest acceptable value for the intended print size. Then I set the aperture to something bright but maybe not the widest to account for focusing at the wrong distance. I let the shutter-speed set itself in that case." Aren't you worried about blurry shots? I would think shutter speed would come first for sports shots, not last. What am I missing? |
