4 Things that affect your pictures… ISO Aperture Shutter Speed LIGHT
Shutter Speed Literally, how long it takes the shutter to open and shut to take the photo. The faster the shutter opens and closes, the less light comes in and out. The less light that comes in, the darker your picture is (when your shutter moves quickly) However, the faster the shutter is, the faster the subjects can be moving in the picture! It’s less likely to be a blurry picture. (A fast shutter speed = good for sports shots)
Shutter speed is measured in fractions of a second. (For example 1/3000 is much faster than 1/30) Unless you’re using a tripod (which we don’t have), you want to use a speed of at least 1/60, or else your shot will be blurry (because your hands move) Shutter speeds typically double with each setting (1/500, 1/250, 1/125, 1/60, 1/30, 1/15, 1/8)
Slower shutter speed. Sometimes, a slower speed can be good. Consider what you are trying to do! Slower is also good for still photography.
Aperture Aperture affects how much light gets in and out. It is the part of the lens that allows light in (like a funnel). It can be opened wide to allow a lot of light in, or closed up to let a little light in.
Aperture works like your eyes. When it’s dark, your pupil gets big to get as much light as possible, but when it’s bright, your pupils get smaller because there’s so much more light! Dark (exaggerated, but you get the idea) More light
Setting aperture Aperture is set in decimals, often called f- stops. It works opposite to what you would think. A HIGHER # = a SMALLER amount of light. Tons of light Some light A bit of light Little light
ISO The measurement of how sensitive a camera is to light It is measured in numbers (100, 200, 400, 800, 1600, etc.), with 100 being the lowest 100 is the least sensitive to light, which means you probably want to use it for a situation that already has a lot of light (typically not nighttime shots)
100 also typically means the clearest, least “grainy” shots. (less sandy looking) Use a higher ISO when necessary to get a high enough shutter speed to freeze camera or subject motion (fast moving shots) Your best bet is to use the lowest ISO you can. Try not to go above 800, since you are not a professional
ISO Settings The best quality photos are shot using the lowest ISO (usually ISO 100). Using a higher ISO results in more noise (grain) and less detail. ALWAYS USE THE LOWEST POSSIBLE ISO IN ANY SITUATION Use a higher ISO when necessary to get a high enough shutter speed to freeze camera or subject motion.
Working together All 3 of these things need to work together for a good photo. Try taking the same photo while adjusting the ISO, aperture, and shutter speed. See the last slide for some example settings.
Notes: Try NOT to use the flash on the camera. Turn it off. Try to use the natural light. Consider using the A Mode if the subject is moving a lot. The camera will help choose a shutter speed for you that way. For now, unless you really KNOW cameras, don’t touch the other buttons. You’ll end up doing something you can’t fix!
To get to the ISO Turn camera on Set to M (for Manual)
Press the button under the letters “ISO” on back panel and hold it down.
Turn the gear on back panel to change ISO as needed. R = up L = down Remember, try 100 first
When the camera turns on, on top you should see the setting for aperture. If you don’t, press “Menu” on the back panel twice. To get to the Aperture
Use the front gear to change the f-stop (it says f it front of it) to what you want it to be.
To get to the Shutter Speed When the camera turns on, on top you should see the setting for aperture. If you don’t, press “Menu” on the back panel twice. Stands for 1/160 in photo
Turn the gear on back panel to change ISO as needed. R = up L = down
Other stuff… Your photo will show up on the back screen immediately after you take it. It will disappear afterwards. To make it reappear, press the play button.
If you don’t like it, press the trash button twice.
Don’t remember your settings? When your photo shows up on the back screen, you can press the toggle button down to get your camera settings. Remember, press the “Play” button if the picture has disappeared.
You should get this screen: And if you press down again, this screen:
–Outdoors, daylight, portrait: ISO 100, f/2.8-4, set shutter speed to match and provide correct exposure –Outdoors, dusk, landscape shot, on a tripod: ISO 100, f/11, set shutter speed to give correct exposure –Indoors, fairly dark, candid photos: set aperture to widest open setting (f/2.8 or wider if possible). Set ISO to 800 or 1600, check to make sure shutter speed is above 1/30 or so. If not you’ll need to add flash. –Indoors, bright, basketball game: ISO 800, widest aperture, keep shutter speed above 1/250. You may have to go to ISO 1600 to do so. –These examples do NOT cover all situations. There are no hard and fast rules – it’s quite possible to shoot indoors at ISO 100 in some situations, and outdoors at ISO 800 in others. You make the call!
