I know this has nothing to do with photography but it does have everything to do with your pets and your bank account, plus I wanted to share with all our readers.
I am an equal opportunity saver, that to say that, I’m not promoting one pet store over another. I just have a coupon for Petsmart.
Remember summer is here so take care of your pets. They are as suseptable to the heat as we are. Water, water and more water.
This pup has it figured out. Stay safe and hydrated everyone.
Dogs do the craziest thing sometimes so you have to be camera ready.
How funny at least we know he can hit a target. This would be way funny if it wasn’t for the fact that he is MY dog. No, I didn’t teach him that trick and YES, I did wash out the bucket and fill it with fresh water.
Now that we’ve talked about aperture, shutter speed, and ISO, it’s time to think about achieving balance. The Tao of using our cameras, so to speak.
To achieve what your camera considers to be correct exposure your aperture and shutter speed need to balance to let in enough light to expose your image. The exposure is the image created by the light entering the camera and being recorded onto the digital sensor. Most cameras these days have a built-in meter to give you the correct exposure.
Yes, your camera gives you the correct exposure but you still have choices to make. Remember your f/stop controls the depth of focus and your shutter speed controls movement.
(depth of field/focus)
4 4.5 5 5.6 6.3 7.1 8 9 10 11 13 14 16 18 20 22 25 29 32
60 80 100 125 160 200 250 320 400 500 640 800 1000
ASA/ISO 100 200 400 800 1600
All the numbers in bold are considered full stops. The f-stop, shutter speed and ISO go hand-in-hand to set the correct exposure. The meter tells you what the light in the room is and you manipulate the f/stop, shutter speed and ISO to give you the look you want.
Stay with me now. You may need to refer to the guide above. If your camera meter reads ISO 400, f/8 @ 125. This is a great standard exposure. But what if you are photographing someone running. 125th of a second won’t stop the action. Your runner will be blurry. You need to increase your shutter speed 2 stops to 500 but if you go up on your speed you have to go down the same amount(2 stops) on your f/stop so the exposure is still correct. That means now your exposure is ISO 400, f/4 @ 500.
So now let’s do a hard one. Your meter reads ISO 400, f/8 @ 125 for a group shot of 20 people. You want 2 stops more depth of field so that’s f/16 but you can’t shoot people 2 stops less 30th of a second because you will likely get blurry people. So how do you make this work? That’s right you change your ISO 2 stops. So your exposure is ISO 1600, f/16 @ 125.
Give it time and practice, practice, practice.
Your shutter speed controls how fast or how slow the shutter door opens and closes in front of the image sensor in your camera.
A faster shutter speeds will freeze action whereas a slower speeds create a blurred effect. When you set your shutter speed on your camera, you’ll see numbers 60, 125, 250, 500, 1000 and so on. These actually represent 1/60th of a second, 1/250thof a second and so on. The higher the number say 1000, the faster the shutter speed and the smaller the number like 15, the slower the shutter speed.
I suggest using a tripod for speeds lower than 1/60th of a second unless you want a blurry image which sometimes is a really cool effect. Fast-moving objects will need a faster shutter speed, around 1/500 of a second or higher, in order to freeze the subject in action.
Your shutter speed is all about controlling action or movement in your image.
One of the most necessary but oftentimes least understood part of photography is Aperture. The size of the aperture, or f/stop, of a lens determines how much of your photograph is in focus. When you hear someone talk about f/stop, they are referring to aperture; the terms are often used interchangeably. The f/stop on a lens range from 1.4 to 22 or higher.
f/ 1.4, 2, 2.8, 4, 5.6, 8, 11, 16, 22, 32 are considered full stops. All cameras have these numbers but you’ll notice that you have way more numbers. If you have a Canon camera generally they incorporate third stops like 5.6, 6.3, 7.1, 8 where Nikon uses half stops. All this to say you will always see the full f/stops consecutively though they may start at f/5.6 and may only go to f/22.
f/stops can be confusing at first. The f/stop numbers refer to how open or closed the aperture on the lens is. f/1.4 would be a wide-open aperture on most lenses, whereas f/22 would be a virtually closed aperture. The WIDER the aperture, the more light that comes through the camera the LESS of your photo will be in focus. So the SMALLER the aperture, the less light allowed the MORE of your image will be in focus.
I have discussed Depth of Field in an earlier post. The reason I mention it here is that your f/stop is part of what controls the focus depth as you can see from the illustration above.
This one is a little harder to get but with practice it will come.
