Shutter Speed

Shutter Speed



Shutter speed affects photographs paired with aperture to affect how much light a camera absorbs in a certain amount of time. The more time you allow the lens to absorb and process light, the more light goes into the final image
In this post Lyndzee Ellsworth (see their blog at epblog.net) shares some images from a shoot to show what impact shutter speed can have on images.
Starting with the first photo, I set the shutter speed for a 15 sec exposure (which on your camera should look like 15”). With the shutter open for 15 seconds, all of the light that the lens can capture in that 15 seconds is recorded and processed. By the photo below you can tell that 15 seconds was too much, so I changed it to 10, then 8 and then finally landed on 5 seconds to achieve what in my eye was the best shot.

Shutter speed can be utilized to capture moving subjects more easily.
The same rule can be used to get the opposite effect. If the shutter speed is set slow, photos can either blur or drag light for the desired effect.

Arperture

                                 Aperture

by Shayna Kavanagh
 An aperture is a hole or an opening through which light travels.
The more light that the lens has access to, the better the photograph because camera lenses rely on light bouncing off of objects to get a picture similar to the one pupils can detect. 


The size of the stop is one factor that affects the depth of field. Smaller stops (larger f numbers) produce a longer depth of field, allowing objects at a wide range of distances to be in focus at the same time.




 The more or less light affects the exposure because an overexposed photograph will blur out the lightest details and an underexposed photograph will blur out the darkest details.



I found it interesting how aperture, which I'd never heard of before today could make you be able to have a picture lit up how you want without editing it. I've kinda always wondered what the scrolling sound in cameras was and now it makes sense so I kind of feel a little stupid but that's that this class is for, hey?
I knew about the depth of field because pretty soon after learning how to work with these cameras I learned it's not as easy as a 'point and shoot' because these cameras actually focus, unlike my phone cameras
