Hello again, time for another mini lesson on your DSLR camera. So…….do you even know what “DSLR” stands for? It’s Digital Single Lens Reflex. Not that that actually means much….but there ya go. =) Light travels through the lens and a mirror is used to reflect a portion of that light through the view finder. Enough technical jargon, let’s have a quick lesson.
Your camera has 3 main tools to consider before taking a photo in Manual mode: ISO, Aperture and Shutter Speed.
Aperture: this is your “F” stop. It will range anywhere from f1.4 (very wide open shutter, letting lots of light in) on up to f22 (very small opening, letting very little light in).
Shutter: this will range from a very SLOW shutter speed (1/8 of a second or slower) to a very FAST shutter speed (1/4000 of a second).
ISO: Usually ranges from about 200 up to 6400.
Time to take a picture.
First, I set my ISO. ISO controls the light sensitivity of your camera. The higher you crank it up, the brighter the image will be. But, the higher you crank it up, the more grain and less crisp detail you will see in the image. So, it’s a love-hate thing. Let’s say I’m outside during the day at the park and it’s fairly bright out. I don’t need that extra light sensitivity, so I turn my ISO all the way down, which is around 200 on my camera.
Next, I want to set my aperture. What am I taking a picture of? Let’s say my son looking up at me from a piece of playground equipment. I would use anywhere from f1.8 to f5 for a single subject. Aperture controls “Depth-of-field,” which is a tough concept that took me a WHILE to totally figure out. I won’t, I can’t, go into it right now, but when you see a picture of something fairly close up in good, crisp focus and the background is blurry, that is a shallow depth-of-field, which usually requires a larger aperture, such as f1.8, f2.8, f3.2 and sometimes even f4. Notice I said “larger” aperture. Yes, the smaller the number, the larger the aperture. So confusing! So anyway, let’s say I pick f3.2.
Lastly, I need to set my shutter. If I already have my aperture decided on, all I need to do is start changing my shutter, looking at the meter inside my viewfinder until the little black tick mark moves to “Zero” like in the image below. When it moves to Zero, that is your camera telling you you have picked the right shutter number to match the aperture you have picked to make correct exposure. Camera is not always right, but this is a great starting point to learn. If you end up with a shutter speed that is below 1/100….then that is probably too slow and will probably be a little blurry, ESPECIALLY if you are shooting a moving object. If you end up with one that is too slow, you can turn your ISO up a notch or two and see if you can get a faster shutter.
Once you’re at zero, snap your pic! However, I hate to be the bearer of bad news, but when your kid moves into different light, you will have to re-meter, and possibly move your shutter again to get back to zero.
Clear as mud?
We would love to help you! Feel free to ask some questions. Happy Valentines Day!
