Desert Springs, November 2011.

Post  Richard on Tue Nov 15, 2011 5:23 pm

My selection of the best pictures I took today.


Aperture f 3.5, Shutter Speed 1/1600, Focal length 30, ISO 200



Aperture f 10, Shutter Speed 1/500, Focal length 80, ISO 200


Aperture f 3.5, Shutter Speed 1/4000, Focal length 18, ISO 200


Aperture f 11, Shutter Speed 1/500, Focal length 105, ISO 200


Aperture f 4.5, Shutter Speed 1/1000, Focal length 35, ISO 200


Aperture f 14, Shutter Speed 1/40, Focal length 18, ISO 200

These are my first attempts using Aperture priority, as opposed to a pre-programmed auto mode. I notice that generally, the shutter speeds are quite high, so perhaps I am getting the aperture settings wrong somewhere. Also, completely forgot to alter the ISO settings!

Richard,

Really nice set of shots, particularly as you were trying Aperture priority mode for the first time.
Thanks for including the image 'exif' information.

Don't worry about altering your ISO setting. This is normally kept at the lowest setting for your camera (mine's is 200) to ensure the highest resolution shots without 'noise'. You would only normally increase your ISO for low light conditions.

Some of the high shutter speeds you had were due to using lower aperture settings, which is fine if you were looking for narrower depth of field, but for 'normal' shots outside on a bright sunny day you would generally be working in the f8 - f16/f22 range.

The higher the f number, the more the lens is closed in, and the camera will extend the shutter speed to get the correct exposure. If you really want a particular aperture, and by doing so you find your shutter speed is too slow to hand hold (below say 1/30th) then you may want to consider increasing your ISO (or reconsider the aperture you want to use).

Hope that makes sense.

Rgds,
Howard Very Happy
