Tip the Scale
Yes, that ever annoying balance between shutter speed and aperture. Wait... WHAT? What the heck is aperture and how in God's green earth does it make a difference?
Yup, this is the trouble I came across last night in my effort to take a night landscape photograph. Well, apparently there are these annoying little things you have to set for... what they call... exposure to light. Meaning... its like.. say someone was trying to surprise you, blindfolded you, took you someplace you had never been before then only allowed you to open your eyes for half a second before asking you, what did you see? Mmmmhmm, darn well impossible, all you get is blur from what few lights there are.
Yes, so the thing that they call Aperture is for creating depth. And this wonderful book beside me, (Digital Photography: A Complete Visual Guide) claims that for a low light image, we want a larger aperture so that we can gather up more areas of light. This can be adjusted by going to your AV setting on your camera dial, OR the M. Aperture is set in 'f' and we want to slow it down, so something around f2.8. Sounds like a way to confuse a person for hours if you ask me. Pffft...
And now for the other end of the scale. Shutter speed. Now according to my previous statement, that if you only get a half second to look then you only get blur, thus we try to have more time before the blink. Shutter speed is the same. To absorb more of the picture, we slow that down as well. TV is the setting for changes of shutter speed, this way we can slow it down to B, pretty much the most annoying setting where you hold down the button as long as you want with hands shaking an blur accumulating, all the way up to.... 1/15, but keep in mind. I've noticed that the longer your shutter peed the darker it claims your photo to be... soooo. best of luck!
I'll be testing out these settings later tonight and let you know what I found to be the best mix. Way too scientific for me though, Haha. If you have the night button setting that could be used just as easily!
