Freezing a droplet of water or a smiling face zipping past you on a bike both require using a fast shutter speed and usually a higher ISO setting. I prefer to set my camera on aperture priority in order to prevent under-exposing my shot. In this shooting mode, using a wide open aperture like F/2.8, F/3.5 or F/5.6 will let a lot of light into the camera, and the camera will then automatically choose the fastest shutter speed it can—given the ISO setting and your lighting conditions. If it is a bright day, the shutter speed will be higher in this mode when using a wide aperture. And the higher you set your ISO, the higher the resulting shutter speed will be. So start with your camera in the “A” or “AV” mode, set the aperture to a wide open setting, and set your ISO at 400. Look thru the camera and see what shutter speed your camera says it will use. If it is slower than 1/500th of a second, then boost your ISO to 800, or 1000. Keep in mind that if your subject is moving very fast, you may need a very high shutter speed, like 1/1000th or 1/1250th in order to freeze the motion. To refresh your memory about aperture priority, take a look at the aperture download card posted here. Take a break from raking leaves, grab the camera and take a few shots of autumn fun. Or, if it is already snowing in your part of the country, take some creative snowball fight shots. Use a fast shutter speed to capture sports action, falling confetti, sprinkler water and more.
I’m using my time in the airport in Palm Springs (I’m painfully early for my flight and it’s 112 degrees outside so I can’t even enjoy the outside cafeteria) to finish and upload the first of what I hope will be many free download cards. These will be a series of cards that you can print out and keep with you to refer to when you’re out shooting. The first is about aperture priority mode. I’ve covered this topic a lot since I feel it is the most important technique to master to make better photos. Understanding what is does allows you to be more creative since you can force the outcome of your image to better tell your story. And we all know practice is the best way to master any technique. So print out this first set of cards on one letter-size sheet of photo paper (luster is best since it won’t scratch as much). Then cut the paper along the grey lines to give you a set of four cards. If you like, punch a whole in the corners and put them on a D-ring key chain and attach them to your camera bag. You could even have them laminated at your local office supply store. This is the first set of Chasing Picture Perfection Tips Cards. Download the file at this link http://www.4shared.com/file/119167214/5e95ce94/TIPS_CARDS_final.html
Fireworks photos are easy to shoot if you have a great position and a stable tripod or surface for your camera (or a lens with image stabilization like my 18-270mm VC zoom). I set the camera to manual mode (off of the program or aperture priority shooting mode I usually use). I also set the camera to manual focus. Since the sky is dark, the camera cannot focus so you need to manually set the lens’ focus ring to infinity. Next, I boosted the ISO to 1000. And finally, I set the lens to my widest aperture (F/6.3) and a slow 1/15th of a second shutter speed. The slow shutter speed captures the streaks of the fireworks’ bursts nicely (but the slow shutter speed can lead to some blur if you are hand-holding or shooting without a tripod and cable release–did you know that even when your camera is on a tripod, the act of pressing the shutter release button can cause blur?). If you get too much blur, move your shutter speed to 1/30th of a second, but your streaks may not be as long. I did have a nice position on the patio of a beautiful bed and breakfast where a friend was staying (we were so pleased that she invited us all to watch with her!). There was a nice break in the trees that looked out over the LI Sound. While the fireworks we saw were not Macy’s quality, they were fun for the kids, we oohed and aahed, and I felt I got a few good shots to include in my scrapbook page for this year’s holiday. Perfect end to a Happy 4th of July Day! (270mm; ISO 1000; F/6.3; 1/15th sec.)
Understanding the function of F-stops, or the aperture of your lens, is undeniably the most confusing of your DSLR’s features. However, once you master it, you will make a huge leap forward in the quality of your photos.
As a photo student in high school and college, I stuck a slip of paper onto the back of my camera (yes, in film days SLRs had a bookplate slot on the back of the camera where you slipped in a flap from your film box so that you could remember what film you had loaded. Can you imagine?!). On this slip I wrote, “open aperture=blurry” and “small aperture=sharp.”
An open aperture lets in a lot of light. On your lens it is a setting like F/2.8, 3.5, 5.6, or 6.3. Think of the aperture as your eye’s pupil. If there is not much light, your pupil gets bigger, or “opens” to let in more light. But a big result of using an open aperture is the effect of a blurry background that really makes your subject pop off the page (or screen). You can easily control the aperture setting on your camera by putting the camera on “A” and dialing in one of the aforementioned numbers. Your camera will automatically pick a shutter speed to make a proper exposure.
If you have a distracting background, dialing in a wider (or open aperture) will make the background blurry and eliminate the distractions. However, maybe you want the background really clear. Like if you’re standing in front of a sign that you want to be able to read in the photo. Then you would dial in a small aperture.
In this first photo, her eye is in focus, but her earring is not, and neither is the tip of her nose. I was just a few feet away and had the camera set to “A” (Aperture Priority) and dialed in F/6.3. Now conversely, if you choose a small aperture, like F/22 or F/32, your background will appear more sharp. Again, imagine a bright sunny day and how your pupils react: they get smaller and let in less light. But also, think about when you squint and how things get clearer. This is sort of how a smaller aperture works. In the second photo, I dialed in F/32 and her earring is now in more focus.
I took about 100 photos of Sydney riding her new bike to show what panning is. Panning is when you follow the action at the same rate of speed as the subject, resulting in a blurry background and a sharp subject. I discovered it is not so easy as it sounds. There are several steps to follow in order to get the result:
1) set your camera to Aperture Priority and select a very small aperture like F/22. This slows down your shutter speed to about 1/25th sec depending on how bright it is out;
2) in order to ensure your camera can select a slow shutter speed, set your ISO to 200;
3) set your camera to continuous shooting and continuous AF; and
4) take lots and lots of shots as the action speeds by you parallel to your camera. Pivot your whole body while keeping the camera level, following the action as it passes in front of your camera. Keep your finger on the shutter release button until after the action has passed you.
The background will be streaks of color (the slower the shutter speed, the more streaky). If your subject appears blurry, you are moving slower than your subject. This technique requires lots of practice. So don’t be discouraged your first time out. The images here were shot at varying shutter speeds and the result in each differs slightly. Notice a nice clean background makes the best image, but this technique also helps to make a cluttered background look better.
I really feel like I cheated to make this picture on our trip to Mexico last week! I used the “night portrait scene mode” instead of bracketing exposures and playing with the flash to get just the right balance of exposure on her while still having a nice sunset in the background. I had literally a few fleeting seconds of her attention before the sun set below the horizon. So I put the camera on a scene mode, which I never do! And guess what? I got one of the best sunset pictures of the trip!
