1  Understanding Aperture – Shutter Speed - ISO

2

3 f stops F stops = The measurement of the aperture setting in a camera lens

4 We will discuss how to do this in a future lesson or watch how at Adorama.com f/2 has a larger opening f/16 has a smaller opening Set it to a low aperture if you want a blurred background, or a high aperture if you want everything to be in focus.

5 The exposure meter allows you to keep your exposure triangle balanced.

6 WHEN CAMERA IS SET TO “A”  Turn the dial in back of the camera until you reach your desired f stop  Notice when you change the f stop, that the camera will automatically change the shutter speed for you.  Pay close attention to the meter – when it is at 0 that’s when the exposure is perfect!

8 Shutter speed is how fast the camera records the picture.

9 WHEN CAMERA IS SET TO “S”  Turn the dial in back of the camera until you reach your desired shutter speed.  Notice when you change the f stop, that the camera will automatically change the shutter speed for you.  If your aperture number starts flashing, that means that the shutter speed you selected is too high to or too low to correctly expose the picture. Moving Objects Turn Dial here

10  ISO is the 3 rd component to the Exposure Triangle and it measures the sensitivity of the image sensor.  If you have your Aperture and Shutter Speed the way you want and you still have too little or too much light, try resetting your ISO  The lower the number the less sensitive your camera is to light and the finer the grain.  Higher ISO settings are generally used in darker situations to get faster shutter speeds – but they can be grainier.

11  Click the Menu button  Use the round dial with the up & down arrows plus the OK button to maneuver around & make selections  Make sure the Camera icon is selected  Scroll down to ISO Sensitivity  Select ISO setting for desired lighting NIKON CAMERA SETTINGS 100 200 400 600 800 1600 Very Bright light Outside settings Indoor settings Very low light

12  Shooting in Manual Mode (“M” on dial) allows the photographer complete control over all settings.  Things to consider:  Pictures tend to come out blurrier, even if you are shooting a still object or person, so use a tripod.  Lighting is extremely important – so pay close attention to the meter when adjusting all 3 exposure settings.  It is really difficult to capture motion in Manual Mode so keep things steady!

13  Hold down the button with the +/- signs on it  At the same time turn the dial with your thumb until you reach your desired f stop Dial +/- button

14  Click the button with the ____ signs on it, then release it  Then turn the dial with your thumb until you reach your desired shutter speed Dial Button

15  You still change the ISO the same as with the other settings  Just remember to try different ISO settings to get different results. NIKON CAMERA SETTINGS 100 200 400 600 800 1600 Very Bright light Outside settings Indoor settings Very low light

16  Light – Is the subject well lit? Lighting is everything!  Grain – Do I want a grainy shot or one without noise? Check the ISO settings.  Tripod – Do I need a tripod? Even the slightest movement will cause the picture to be out of focus.  Moving Subject – Is my subject moving or stationary? So should I be in “A” or “S” mode?  Settings – Have I checked all settings and is the meter balanced?  Plan of Action – Have a well thought out plan of what, who and where you will be shooting before you begin shooting.
