Once again, we converge on convergence: The Samsung Galaxy Tab S2 NOOK brings together, under one set of covers, an eReader for books, a small but powerful computer, a video and audio player, some phone functions, and a camera. Let me de-converge that just a bit: Some would argue that it makes compromises at every turn with each of its functions. That’s probably true, but having almost-everything-in-one-place is a beautiful thing.

This chapter looks at the Tab S2 NOOK as a camera. Actually, it has not one, but two cameras — one on the back and the other on the front. They can take pictures or video.

remember Use the rear camera for pictures that you want to print or otherwise view at a size larger than that of the screen on the tablet.

I still laugh when I see people holding a tablet at arm’s length and tapping at the screen to take a picture. It’s a bit awkward and hard to control. But still, it’s a camera and the result is still a digital photograph that can be stored on the tablet, sent to someone else’s digital device, or sent out to a photo lab for a print.

Taking Pictures with a NOOK

On the plus side, the cameras in this NOOK can immediately display the pictures or videos you make (and with a screen considerably larger than the ones on plain old digital cameras or smartphones). On the downside, although the electronics of the camera in all tablets are quite advanced, the fact is that none of them can match the quality of the large lens on an advanced camera.

In addition to being an author, I am also a professional photographer and I travel the world with a camera that cost several thousand dollars and a zoom lens that cost a few more; my photography kit also weighs about four pounds. And when I need it, I also add in an electronic flash unit that adds a pound and costs more than a few pence.

So back to convergence. When it comes to owning a device that has so many functions and yet costs only a few hundred dollars and fit in a coat pocket and weigh just a few ounces, less just might be more in most situations. In this chapter I show you how to use the tablet’s cameras in automatic mode and give some hints on how to make some advanced adjustments that bridge some of the gap between point-and-shoot and professional equipment.

tip The Tab S2 NOOK doesn’t have a flash or LED light, so your source of light has to come from somewhere else. That isn’t a big deal in most situations. Use the sun outside or a lamp indoors to light your subject. And here are a pair of tips to help with faces or details:

  • Outdoors, have an assistant hold a white card or something similar to reflect sunlight onto a face.
  • Indoors, turn up the lights and have someone standing outside of the image aim a light at faces or objects you want to brighten.

You can create a gallery of images on the tablet and do some basic editing, and you can share them by email, social network, or upload or transfer your files to a photo printing service and get decent prints. Think small: A 4x6-inch or 5×7-inch print should be sharp and pleasing, and photos taken in bright light should be fine at 8×10 inches. Larger than that, not so much.

Taking a Camera Tour

In Figure 11-1 you can see the basic camera controls. I go through them briefly here and examine them in more detail later in the chapter.

image

Figure 11-1: The basic camera controls for the Samsung Galaxy Tab S2 NOOK.

Camera controls for the upper screen

Start the tour in the upper-left corner and work your way across the top first:

  • Settings. I’ve already noted how this NOOK tablet is nowhere near as advanced as a professional camera. However, you can make lots of manual adjustments here, including whether you want an image taken at full resolution or at a lesser resolution (which creates a smaller file). You can ask for grid lines on the screen to help compose your image. I explain more later in this chapter.
  • Aspect Ratio and Resolution. You won’t see those words on the screen, but that’s what the two sets of numbers mean. In Figure 11-1 you can see the upper number of 4:3, which means the aspect ratio is the equivalent of an image about 8 inches tall by 6 inches wide in portrait mode (taller than wide), or 6 inches tall by 8 inches wide in landscape mode (wider than tall). The Tab S2 NOOK uses a more book-like ratio than other tablets, many of which use a 16:9 ratio, more like a widescreen television.

    The other number is the resolution, or number of pixels (picture elements or individual dots) captured by the sensor. The more pixels the sharper the picture, and also generally the larger it can be displayed or printed.

    You can’t independently select resolution or aspect ratio. See Figure 11-2. Here are the combinations available for the rear camera, the one facing away from the screen:

    • 8.0 M (4:3). 3264×2448. This is the standard setting, capturing as many pixels as possible and presenting them at a 4:3 or 3:4 ratio.
    • 6.0 M (16:9). 3264×1836. A slight reduction in the total number of pixels collected, although that usually doesn’t matter since the size is also smaller in the 16:9 or HD-like aspect ratio.
    • 6.0 M (1:1). 2448×2448. A high-resolution square image that can be used for standard photos or for portraits for mug shots on Facebook or LinkedIn or other social or professional network pages.
    • 4.9 M (4:3). 2560×1920. A reduced resolution version of the 4:3 aspect ratio.
    • 3.6 M (16:9). 2560×1440. A reduced resolution version of the 16:0 aspect ratio.
    • 3.1 M (4:3). 2048×1536. In relative terms, a low-resolution 4:3 photo.
    • 2.4 M (16:9). 2048×1152). In relative terms, a low-resolution 16:9 photo.

    tip Shoot at lower resolution if you have limited space for storage in the internal memory or an external SDHC card installed in the tablet. I prefer to have a large SDHC card and transfer my images to a desktop computer for editing. As far as aspect ratio, it’s entirely a matter of personal choice.

    tip You can shoot an image at high resolution and later send a smaller file as an email attachment. Visit the Google Play Store for free or paid apps that let you adjust the file size. Save a copy of the picture with a different name; that way you have the high-resolution image and a smaller file to share.

image

Figure 11-2: The available picture sizes and aspect ratios for the rear-facing camera.

There’s a similar set of adjustments for the front camera, although that one starts out at a much lower resolution of 2.1 megapixels:

  • Timer. Tap to enable a countdown timer before the picture is taken. You can use this as a self-timer so that you can run around and get into the image or for other special requirements you might have timewise. Your options here are Off, 2-, 5-, or 10-second delay. Or you might experiment with having the tablet take a candid camera shot all by itself.

    warning Be careful about propping your tablet and then running off to get into a photograph. You don’t want the tablet to tumble.

  • Effect. Tap here to add an effect to a photo. You can preview the effects on screen before selecting one. See Figure 11-3. Special graphical effects include these:

    • Vintage. A sort of faded or low-saturation color, like an old photo found in the bottom of a drawer somewhere.
    • Vignette. Another old-timey effect, with darkened corners.
    • Tint. Something like a duotone, mixing a bit of orange over top of a grayscale image.
    • Grayscale. No color, just glorious black and white. You’ll get best results with strong, contrasty lighting.
    • Faded Color. Another version of vintage.
    • Moody. A dark, low-contrast grayscale image.
    • Cartoon. What’s not to like? A compressed color range, low contrast, and just plain odd. In Figure 11-4, I combined the Cartoon effect with a forced shift in Color Balance. Go forth and experiment; film is free.

    remember You have to enable an effect before taking the picture.

  • Download. Remember, your NOOK is a computer, and that means it is almost infinitely configurable. With a connection to the Internet through Wi-Fi, tap on Download to hunt for other effects you can obtain from developers; some are free and some ask for a few dollars.

Figure 11-4: Playing around with the Pro settings, I selected the Incandescent white balance setting for a daylit room and then applied the Cartoon effect. This isn’t the way the breakfast nook usually looks, but I like the result.

Camera controls for the bottom screen

Move now to the controls at the bottom of the screen, starting at the left corner:

  • Mode. Jumping over to the bottom of the camera screen, tap here to select from interesting special effects or controls. You can take manual control of the sensor’s sensitivity (ISO), use automatic or manual white balance, and compensate or adjust exposure by as much as two stops. (Each stop is equivalent to half or double the amount of incoming light, depending on whether you choose to under- or overexpose the image.)

    remember Not all modes are available on both the front and rear camera.

  • Switch camera. Tap here to swap between the rear camera (the one that’s on the side away from the screen) or the front camera (which looks you right in the eye). The icon shows a camera with left and right arrows. In most instances you’ll use the back camera for landscapes and portraits. Use the front-facing camera for video calls and selfies (self-portraits).
  • Take a picture. Tap the icon on a camera to actually snap a photo, which is, of course, one of two reasons we are gathered here.
  • Record video. Your other option is to tap the movie camera icon, which starts the recording of a video.
  • Gallery. Tap the icon to look at the most recently taken photo or video, as well as all others stored on the device. From the Gallery, you can share your work with others by sending it over the Internet. And you can perform other actions on the files.

Tap-Clicking with a Tablet

remember Are you ready to use your tablet as a camera? From the Home screen, scroll through the app icons on the lower part of the screen; tap the Camera icon. Or, you can tap the Apps icon on the Home screen and find the Camera icon there.

After a brief interlude during which the tablet changes its personality, you see the main camera screen, as you saw in Figure 11-1. Tap the shutter to grab a photograph. But before then:

  • You can hold your tablet camera wider or taller. The buttons and controls will stay where they are on the screen, but their labels will rotate as you turn the tablet.
  • remember To tell which camera you’re using, look at the screen. If you see whatever’s in front of the tablet, you’re using the rear camera. Some of you, I’m sure, are at this moment halfway down the rabbit hole with Alice in Wonderland. Remember that the front camera is the one on the front, which is the side you use to see the screen; the rear camera is on the back.

  • To switch between the front and rear camera, tap the camera icon that has left and right arrows. Each time you tap it, you switch between one lens or the other. If you see your own face, tap once to use the rear camera.
  • warning If the tiny lens on the back or front of the tablet gets dirty, your pictures are going to appear smudged or otherwise less-than-lovely. Gently clean the lens with a soft cloth or a tissue. If the lens has some sticky gunk on its face, you can slightly moisten the cloth with just a bit of water or a lens-cleaning solution like the ones used for eyeglasses. Don’t press hard and don’t assault the lens with a nail file or jackhammer.

  • On the screen, tap the spot you want to focus on. In certain combinations of light and modes, you may be able to shift the point of focus slightly. For example, if you’re taking a picture of a person standing in a field of sunflowers, tap that person’s face so that he or she’s in focus. Or, tap a distant sunflower to emphasize the beauty of nature over your friend’s face.
  • Touch the screen with two fingers and spread them apart to zoom in as much as 4 times; pinch your fingers toward each other to bring the zoom back toward 1 time. You can also touch and hold the slider that appears on the screen to manually adjust the amount of zoom.

    The zooming range of the tiny camera system is limited, and it’s electronic rather than optical. The Tab S2 NOOK relies on enlarging a portion of the image captured on the sensor; extreme zooms of distant objects or people will lose a little — or a lot — of quality.

  • You’ll see a short lag between the moment you tap the shutter and when the photo’s recorded. This is the price we pay for all of the automated functions that are handled for you by the tablet camera: exposure calculation, white balance adjustment, and autofocus. This makes it a little more difficult to take action photos; practice a bit to learn how to anticipate motion. And don’t hesitate to reshoot if someone has blinked or made a face.

Choosing camera shooting modes

If you’re the sort of person who owns a microwave with a clock that constantly flashes 12:00 as the time of day, or prefers to scrunch your knees up against your chin rather than adjust the seat in your car, you just might be missing some of the finer things in life. We live in a customizable age, and as I’m sure you’re beginning to figure out, your Samsung Galaxy Tab S2 NOOK has a button or slider or control for just about everything.

These sections concentrate on the camera’s shooting modes. Because the rear-facing camera is better and generally serves different needs, some of its modes are different than those on the front camera.

remember Here’s how to adjust modes: From a Home screen, tap the Apps icon and tap Camera. Then tap Mode. The following sections explain the selections you can make.

Shooting modes for both cameras

These modes work for either the front or rear camera:

  • Virtual Shot. Create 3D-like multidirectional views of objects. This is a truly amazing feature, although I’ll be the first to admit that it takes a bit of practice to get it right.

    The Virtual Shot, also called Virtual Tour in some descriptions, allows you to create a walk-through of your surroundings, like circling a 3D object. For example, you could tour your home or office, or document all the facets of a statue in a museum.

    When you enable the feature within the Camera app, do this:

    • Look at the screen and find the target pointer.
    • Adjust the way you hold the tablet so that the pointer’s in the center of the circle.

      When the target dot is in the center of the circle, it automatically takes a picture.

    • Follow the onscreen prompts to move the view to the next spot in your tour.

      Hold the tablet as steady as you can and at the same distance above the ground. Each time the target circle appears, this tells you that an image has been captured and stitched into the tour package that you are preparing.

    • Press the Stop button when you’ve completed the tour.

      You can view the results in the Gallery on your tablet.

  • Download. Access and install additional shooting modes from Samsung’s Galaxy Apps store.

Shooting modes for the rear camera only

Tap Mode to see seven available special shooting styles, as shown in Figure 11-5:

  • Auto. This standard point-and-shoot setting lets the camera choose the best settings. It’s usually pretty good, but sometimes we humans like to believe we are just a bit smarter than a machine; occasionally we are.
  • Pro. This is, in most respects, the opposite of the Auto setting, allowing you to adjust the sensitivity of the camera’s sensor, as well as choose exposure values, white balance, and color tones.
  • ISO. Your camera’s sensor is the replacement for film, and like film it can be more or less sensitive to light. In film-based photography, this used to be called the ISO value. Going for a high sensitivity, or a high ISO, allows you to take pictures in low-light conditions, although the higher the ISO, the greater the possibility of noise (graininess) in your image.

    The Galaxy Tab S2 includes manual settings between 100 and 800. In most situations you’ll want to use the Auto setting, but if you’re taking photos in bright sunlight of fast action (beach volleyball, perhaps?) you might want to experiment with a high ISO of 800, which will force very short shutter speeds to freeze the action, or an ISO of 100, which might produce a bit of interesting blur.

  • White Balance. Light is made up of the visible spectrum, which is another way of saying that the color of light varies based on the time of day or the nature of artificial illumination. The early morning is usually cool or bluish; sunset is usually warm or toward orange.

    An indoor incandescent light is much warmer (toward the red or orange) than fluorescent lights or daylight. The tablet computer is pretty good at adjusting for the prevailing light condition, but just as one example you might want to play around with this setting in unusual situations that mix light coming through the window and electrical or candlelight inside a room.

  • Metering. Your tablet makes the best possible exposure, adjusting the shutter speed (the amount of time the sensor records light) as well as the sensitivity of the sensor itself. But your Galaxy Tab S2 NOOK (and even professional photo gear) can become confused in a situation that has a wide range of light levels in the same scene — for example, a sunny day at the beach with deep shadows under umbrellas and extreme highlights dancing on the surf. If I weren’t so hard at work writing this chapter, I’d be off to the beach right now although there’s a fall-like nip in the air and the seals are still feeding and the sun is near setting, which means the Great White shark population is thinking about dinner. I think I’ll stay at the keyboard.

    Figure 11-6 shows your options:

    • Center-Weighted makes exposure decisions based mostly on the lighting conditions in the middle of the scene. If you choose this option, put the most essential element of your picture in the middle of the image; that’s not always the most aesthetically pleasing composition, but you can always crop the image later.
    • Matrix has nothing whatsoever to do with Keanu Reeves and an artificial reality set up to control human minds. The Matrix setting averages out the entire scene to come up with the best exposure setting.

      tip Matrix metering works well when the range of light is consistent — in other words, scenes where the darkest dark and lightest light aren’t all that far apart.

    • Spot is a good one for attentive, patient photographers. The tablet sets the exposure based on wherever you tap the image. The trick is to find a place that’s best for the image you want to record. Tap a face to expose best for that part of the picture, for example.
  • Panorama. Use the tablet’s brain to stitch together multiple photos into one large panoramic image; this is the same idea as Virtual Shot, which I discuss earlier, except that the result is a single stitched-together image instead of a computer-created simulated video.

    Brace yourself and keep the tablet as steady as you can as you slowly move it in an arc from left to right or right to left. You’ll see a blue guide frame on the screen; when you move the tablet so that it fills the guide frame, it takes the next picture in the series. To stop shooting the pano, tap the Stop (square) icon. Panorama mode automatically stops if it can’t recognize elements of the previous picture.

    tip Panoramas work best when there are simple but recognizable backgrounds, like trees or windows. Shooting against empty skies or blank walls may confuse the camera, which may confuse the image, which will confuse you when you try to make sense of what you’ve got.

  • Virtual Shot. A computer-stitched-together panorama movie made up of individual images.
  • HDR (Rich Tone). This option gives you an image that records only HDR (high dynamic range) tones. Your camera takes three quick pictures at different settings and then combines them into a single image that includes exposure values you wouldn’t ordinarily be able to record directly. For example, it can deal with both deep shadows and brightly lit objects.

    tip HDR won’t work well if the object is moving fast or if you’re moving the tablet as you take the picture.

  • Shot & More. When you take a burst, or series, of photos, this mode can allow you to apply special features such as best photo, best face, drama, and panning shots. Remember: “Film” is free, so experiment to see if the tablet can see something you might be missing.
  • Dual Camera. Again, this is a strange feature but sometimes worth an experiment. This mode takes pictures or videos in a variety of styles using the front and rear cameras at the same time. There you are in the image, and there is what you are looking at.

Figure 11-5: Choose your rear shooting modes from here.

image

Figure 11-6: You can choose amongst three types of metering of exposure for images. Most people use either Matrix or Center-Weighted.

Shooting modes for the front camera only

These settings only work with the front-facing camera:

  • Selfie. Yes, here’s the way to take a picture of yourself with the Taj Mahal over your shoulder, or a photo of you posing with the President of the United States or your bridesmaids or some random dude. You’ll see the image on the screen of the tablet before you take the picture. You can apply effects to make yourself look less like yourself, if you want.
  • Interval Shot. You can have the camera shoot a series of shots at a set interval — every few seconds or every few minutes — and then choose the best images from the group. (Are you thinking this might be a way to discover who is stealing the candies from the jar on your desk? It just might be enough to send the felon away to the big house.)

Making camera settings

If you’re into making minor adjustments, check out the following sections, which I grouped together in what Samsung calls Camera Settings. The options vary depending on which camera you’re using, and sometimes on the mode you’re in.

Tap the Settings (gear) icon and choose Camera to apply the settings you want.

Camera settings for both cameras

Tap Settings from the Camera screen to customize more details of the camera. See Figure 11-7.

  • Grid Lines. This tells the camera to display a set of grid lines on the screen as you prepare to take a picture. This is helpful in making sure the horizon is level or that buildings are upright and not tilting (with the possible exception of the Leaning Tower of Pisa). The grid lines are visible only when you’re taking the picture; they aren’t recorded in the file.

    tip Grid lines are, for me, are essential when holding a thin, flat, rectangular tablet camera at arm’s length. It’s considerably more difficult to hold a tablet camera steady than a standard camera held at your eye level and braced against your face.

  • Location Tags. Your Galaxy Tab S2 NOOK has a built-in GPS receiver, which can tell the device where in the world you are. This function records that information (as latitude and longitude) in the data for the file; you can later use an app on your tablet or a program on a desktop or laptop computer to look up the location of those geographic coordinates and tell you where the picture was taken: Pisa, Italy at 43°43'N, 10°24'E.

    The strength and accuracy of GPS signals can vary from place to place. Sometimes they’re weak inside buildings or in areas between buildings where the view of the horizon is blocked. Weather conditions can also affect GPS signals. If you leave Location Tag turned on, the tablet applies the last good signal it had to your photos, updating your position any time it can. See Figure 11-8.

    warning In a perfect world, most of us would say, “Yes, of course. What a nifty special feature.” But some people worry about privacy. What if that picture ended up in the hands of someone else — someone you don’t want to know where you were when you took the picture? If you send your pictures to someone else by email, or especially if you upload them to the Internet, you lose control over whatever information is embedded in the file.

  • Review Pictures. You can turn on or off the brief display of pictures after you’ve taken them. I generally leave this on, so that I can review the photos to make sure that there’s not a fern growing out of cousin Arthur’s head.
  • Storage Location. If you install a microSD card in your Samsung Galaxy Tab S2 NOOK (which I recommend), here’s where you can tell the tablet where you want your photos and videos stored.

    remember In general, you should store your photos, videos, music, text files, and the like on the memory card and leave the built-in memory for apps.

  • Volume Key Function. Your options are
    • Zoom Key. Pressing the + or – side of the Volume key zooms you in or out; your Volume key is set up this way already.
    • CamKey. You can make the Volume key into a shutter release key for photos.
    • Rec Key. If you make the Volume key work as a Record key, pressing it in the Camera app starts or stops recording a video.
  • warning Reset Camera Settings. If you’ve adjusted your camera — and I hope you will — you can quickly return all settings to the original — like when first you unboxed your Samsung Galaxy Tab S2 NOOK. This is an all-or-nothing reset, and it only affects camera settings.

Figure 11-8: What a world! You can use your tablet’s GPS system to add location information to your photos, and then you can worry about someone spying on you because you did.

Camera settings for rear camera only

  • Video Stabilization. This little bit of technical magic slightly reduces the effects of shakes or bounces while the video camera is recording. I say slightly.

Camera settings for front camera only

  • Beauty. When the camera detects a face, it sets exposure so that skin tones are well lit and skin is smoothed, a makeover without makeup or surgery. It works better in close-up portraits than in distant images, and some results are better than others.
  • Gesture Control. More magic: Hold the palm of your hand out, facing the camera, and look for a yellow box on the screen surrounding your hand. Now take your hand away and the camera will take a picture a few seconds later.

Making Movies

The standard setting for the rear camera is high (or normal) resolution. The Samsung Galaxy Tab S2 NOOK uses the MP4 file format for videos. Note, too, that video files can be quite large; a 10-second clip at full resolution occupies about 21 MB of space.

Tablet, camera, action!

Recording video

remember You can only use the rear camera, the one facing away from the screen, to record videos.

To make your own video, do this:

  1. Open the Camera app.
  2. From the main screen, tap the video camera icon on the right side of the screen.

    If you most recently used your camera for video, the icon should already display that icon.

  3. To start making a video, tap the Record (red dot) icon.

    You can momentarily halt recording by tapping Pause.

  4. Tap the Stop (square) icon when you’re done.

remember Keep these things in mind when you’re recording:

  • Hold the camera tablet as steady as you can. Bring your elbows in to your chest.
  • If you plan on panning (moving left or right, or vertically), do so slowly and smoothly.
  • Record in a well-lit setting: outdoors in daylight or using lamps indoors.

Zooming in or out

While you’re using the video camera, zoom in or out to make distant people or objects appear closer or return to the normal view. Touch two fingers on an image and then spread them apart to zoom in. Bring the two fingers toward each other (pinch) to zoom out.

warning Extreme zooms are pretty poor quality. Judge for yourself whether a video (or camera) zoom is acceptable.

After you record a video, you can

  • Review it by tapping the Gallery window within the camera screen.
  • Close the Camera app and tap the Gallery icon from the Home screen. There you’ll see a collection of both still and video files. Tap any thumbnail (small picture) to view.

I discuss the Gallery app in detail in Chapter 12.

You can buy apps that allow you to edit the videos you make on your Galaxy Tab S2 NOOK. Some very basic ones allow simple cuts and edits, while advanced apps let you fade from one scene to another or apply other sophisticated transitions. You can also email or load your video file from the tablet to a desktop or laptop computer and use a full-featured video editor to make your own movie. That includes reordering scenes and merging videos taken at different times or different locations into one movie.
