When we got our camera I spent about 20 minutes looking at the manual and gave up. It was way too much information making it way too complicated for a newbie DSLR user like myself. It was just TMI. All I wanted was the basics. Just enough for me to understanding the most basic function of each setting. A year later I sat down, did some internet research and pared down the volume of information so I could figure this thing out. Finally, instead of randomly changing the settings around until my image stopped being black I was able to make educated guesses about what settings to use in different conditions. I spent all last weekend taking pictures at home trying to get better at this.
There is so much to learn about manual mode and how to take great pictures. This barely scratches the surface. Once you understand the settings there is still a lot to know about how to manipulate them in relationship to each other to get the shots you want. Never mind all the skill and practice it takes to really be good at it. It's enough to get started without making it more complicated then it has to be for a beginner. Everyone's brain works differently so this may or may not be the key to unlocking the mystery of manual mode but it's been very helpful to me.
Shutter Speed
Amount of time that the shutter is open. Length of time that your image sensor ‘sees’ the scene you are attempting to capture. Measured in seconds (i.e.: 1/60 or 1/80)
Example: Think of how window shutters work. The speed at which you open and close them controls how much light gets into a window. The lower the bottom number is the slower the shutter is being closed and more light is allowed in.
Slower Shutter
- Lets in more light
- Brightens image
- Captures speed and movement in an image
- For use with a Tri-Pod
Faster Shutter
- Lets in less light
- Darkens image
- Freezes the moment and reduces the effect of camera shake.

Aperture
Size of lens opening with which the picture is taken. Measured in F-stops (i.e: F7.0). The larger the F-number the lower the Aperture. Example: Think of it as a window that lets in light. A larger window (larger aperture) lets in more light and will have a smaller F-stop. This one gets a little confusing because large equals a lower number.
Larger Aperture (Smaller F-Stop Number)
- Larger hole (more light gets in)
- Brightens image
- Large Depth of Field: Most of your image is in focus with clear background details
- Landscape shots
- Smaller hole (less light gets in)
- Darkens image
- Shallow Depth of Field: Only part of the image will be in focus with blurred background details
- Portrait shots
Here I am wearing my low ISO Sunglasses outside // Please excuse the duck lips, don't know what I was thinking |
ISO
Measure of digital camera sensor’s sensitivity to light. The image sensor converts an optical image into an electrical signal.
Example: Sunglasses. Dark sunglasses block light so we wear them to lower our eye's sensitivity to the bright sun. So think of using a low ISO as putting on sunglasses when you are outside because you need to lower the amount of light getting into your eyes. When you are inside you don't need to block out light, you actually need more of it to see so you take your sunglasses off.
Lower ISO
- Less sensitivity to light
- Darkens Picture
- Outdoors or in a well lit area
- Sharpens Image
- Still Shots
- Tripod
Higher ISO
- Greater sensitivity to light
- Brightens image
- Indoors or in a dimly lit setting
- Add grain to image
- Action Shots
