GYMNU BLOGS: HOW TO USE DSLR CAMERA- A BIGGINER GUIDE

A BEGINNER’S GUIDE TO YOUR DSLR CAMERA

Let’s start with some vocabulary.

DSLR stands for digital single-lens reflex camera. Basically, this means that when you use the viewfinder on your DSLR, you are seeing through the camera’s lens (by way of a mirror). Many DSLR’s now allow you to use the LCD screen to frame your shots, but I highly prefer to use the viewfinder.

Shutter speed – How fast the camera’s shutter opens and closes to let in light. This is measured in a fraction of a second. 1/15 = one fifteenth of a second, etc.

Aperture (f stop) – How wide the shutter opens. The aperture controls how much of the photo is in focus. The lower the f stop number, the more light the sensor will receive. The picture will be brighter, but a smaller area will be in sharp focus. The higher the f stop, the more area will be in focus.

Shutter speed and aperture work hand-in-hand. They both control how much light the camera’s sensor receives, but in different ways.

ISO – How much light the sensor absorbs. A higher ISO setting will allow the camera’s sensor to absorb more light, thus allowing you to get away with a higher shutter speed. However, the higher the ISO, the more grainy the picture will appear, especially if you plan to crop the photo.

Your camera’s modes will depend on which model you have, but here are the basic ones:

Tv mode – Time value. You choose the shutter speed, the camera sets the other values to “match.”

Av mode – Aperture value. You choose the aperture, the camera sets the other values to “match.”

M mode – Manual mode. You choose it all!

Here’s an example of how aperture and shutter speed work:

This photo was shot with a shutter speed of 1/40 and an aperture of f = 4.5. The shutter speed was too fast for the amount of light in the room, so the photo is too dark.

This photo has the same aperture, but I slowed the shutter speed down to 1/8. The photo is brighter, but since the shutter was open longer, the subject needed to hold still longer. Hard to do with kids, hence the blurry hand!

Your DLSR is heavily dependent on your lighting, especially when taking photographs of kids. The first two photos were taken using the overhead room light. This next photo was taken in front of a window on a bright sunny day, so the light is natural and pleasant. The f stop is 1.8 (shutter open very wide, less area in sharp focus) and the shutter speed was 1/30.

The type of lens you use can make a big difference in the quality of your photos as well. Last year, I received a 50 mm fixed focal length lens for Christmas. This lens allows me to use a low aperture (down to f stop 1.4) which creates a very sharp (but small) area of focus and a nice artistic looking blurry background. The other morning, I shot this photo of Janie dressed up for church:

The combination of this lens (often referred to as a portrait lens) and wonderful natural light from the windows in our game room allowed me to get some fantastic shots. Notice how the focus is on her eyes, and the background is nicely blurred.

But what about less-than-ideal photo situations?

We had one of those this past week. Jordan’s sister and her family were in town, and we had a precious day together – and one shot to get pictures of all the cousins together. The light in our living room was poor (the overhead light makes photos look very orange, which can be corrected to some degree by changing the white balance from “auto” to “tungsten lighting”) and we do not have windows in that room that face toward the sun. Plus, we had 7 kids to photograph, and it was next to impossible to get them all to stand still at the same time!

I managed to pull off this photo with a f stop of 4.5 and a shutter speed of 1/25. A faster shutter speed would have been better, but this was not possible with the amount of light in the room (unless I used the flash).

I sharpened this photo slightly using picmonkey.

For gift opening, I gave up on not using the flash! My best photos were in Tv mode (shutter mode) with a shutter speed of 1/50 or 1/60 and the flash ON.

Bad photo: (too blurry because the shutter speed was not fast enough)

Good photo:

If you must use the flash, turning up the ISO speed will increase the range of the flash, which helps to eliminate the dark background.

This also allows you to use a higher shutter speed, which means a sharper image. The downside is increased grain to the picture. For example, here is a picture with a shutter speed of 1/50, aperture of 4.5, and ISO at 100.

How to take better pictures with your DSLR

This one is the same settings (1/50 and 4.5) with ISO at 800. I also did some editing – brightened slightly, color temperature adjusted – cooler, and photo sharpened.

But the best photos are still the ones with natural light. Not direct sunlight, but good ambient light.

To wrap up, here are some troubleshooting tips:

Too blurry? Increase the shutter speed. A shutter speed of at least 1/125 is ideal for sharp photos. If you must use a slower shutter speed because of lighting, ask your kids to “freeze!” or use a tripod. UPDATE: I upgraded cameras to a Canon 6D, and I am LOVING the higher shutter speeds! Because this camera has a larger sensor, I can take pictures in low light with a much faster shutter speed than my old camera. This makes a huge difference, especially indoors.

Too dark? Slow down the shutter speed or lower the f stop number (aperture). OR, move near a window, open the blinds, or go outside.

Increase the ISO to compensate for low light. How high? I think it depends on the camera. My camera gets grainy at 800 and noticeable grainy at 1600. However, I’ve heard from friends that a better camera can handle a much higher ISO setting without causing a grainy picture. UPDATE: My new Canon 6D can go up to an ISO setting of 12,800 without grain.

Avoid taking photos in direct sunlight during the brightest part of the day. You will end up with harsh shadows on faces, and squinting kids. An hour after sunrise or an hour before sunset is really ideal for the portrait look you see on Pinterest.
