BACK TO BASICS  - Taking Photos with Your iPad (and iPhone)

By Jim Cerny, Columnist, Sarasota TUG, FL -   Sarasota Technology Monitor

Your iPad tablet device (and your iPhone) are excellent devices for taking photos and videos. We will discuss taking and working with photos in this article, but taking videos is similar. All iPads and iPhones have a “Camera” app to TAKE photos, and a “Photos” app to VIEW your photos.

 THE CAMERA APP -- Tap this app to begin using the iPad built-in camera. Immediately you will see an image of what your iPad camera is seeing through its lens. Move your iPad to see on the screen what you want to take a photo of, wait a moment for the image to focus (you will see a small yellow-outlined rectangle on the image as it adjusts the focus). You may tap on the image anywhere to move this focusing rectangle to another place if you wish, then tap the large white button. You will hear a “click” and your photo is now saved on the “camera roll” on your iPad. (Before taking your photo, you can “zoom in” by touching the screen with two fingers and spread them apart.)

When you are using the camera, you can tap on the small white camera outline icon to switch between the front or rear lens of your device. The front lens (facing you) is best used during Skype or video calling. Some settings for your camera can be changed in the “Settings” app, such as turning a grid pattern on or off. The “HDR On” option (just touch to change to “HDR Off”) will allow your iPad to take three photos at almost the same time and provide one best photo using the three images. (I have noticed no significant difference whether HDR is on or off). In addition to the “photo” option, there is the “video” option (to take videos, obviously) and a “square” option for taking square (i.e. not rectangular) photos. Scroll to chose. Your most recent photo will be shown at the bottom corner of the screen and you can touch this photo to open the “Photos” app.

 THE PHOTOS APP -- Touch this app to open and view your photos. You can scroll through all your photos in your iPad memory and they are already sorted by date. To delete a photo, touch it to open the photo on the screen, then touch the little blue garbage can in the bottom corner of the screen. Touch on “Delete Photo” when it appears to confirm the delete. Your photos can be used in various ways, printed (if you have a printer that works with your iPad), sent to other places, etc. You can also organize your photos into ALBUMS. You can think of an “album” as a “folder”. You can create a new album by touching the “album” icon at the bottom of the screen which opens your list of albums, then touch the “+” to add a new album and give it a name. At this point you will see your collection of photos and you can “select” the ones you want to “copy” into that album. A photo you have “selected” will have a blue circle with a checkmark in it on the photo. You can copy the same photo into multiple albums if you want. If you DELETE a photo from an album you are only deleting the copy you put in that album. If you DELETE a photo from your “photos” (that is, you are NOT in viewing albums) then that photo will be deleted from your device including all the albums you copied it into.

FUN TIP: To take a photo of whatever is on your iPad screen at any time, just hit the “home” and the “power” buttons at the same time.

You can download any number of free and low-cost apps that will work with your photos and allow you to edit and enhance them. However, the Photos app that comes with your iPad can do some editing. Touch “Edit” at the top right of the screen when you have selected a photo to see your options – such as rotate, enhance, filters, red-eye removal, and crop.

The camera of your iPhone will work the same way. The iPhone will have a flash built-in, whereas the iPad does not.

MORE TIPS:

  • It is a good idea to backup your photos somewhere else for safekeeping. You can do this when your iPad (iPhone) is connected to your computer or you could save your photos to some memory in the “cloud”.

  • Take photos and experiment with them. Learn how to find them and organize them into albums.

  • Learn more by using Google and YouTube – ask questions such as “How do I delete a photo from my iPad?”

  • Review your photos on your device on a regular basis and DELETE the photos you no longer want. (If you can NOT delete a photo then the photo was most likely put on your device from someplace else.)

  • Having your iPhone with you means that you have never forgotten your camera at home or in the car!


Stepping up your Internet privacy and security

Meeting review by Mike Hancock, Newsletter Committee, Golden Gate Computer Society

GGCS newsletter     www.ggcs.org     editor (at) ggcs.org

Noah Swartz, a technologist with the nonprofit Electronic Frontier Foundation (EFF.org), explained that EFF is involved in Impact Litigation and projects like HTTPS Everywhere, Let’s Encrypt, Panopticlick, and Privacy Badger.

Privacy Badger 1.0, created by EFF, is a free open-source (GPLv3) web browser extension for Google Chrome and Mozilla Firefox, for both PC and Mac. Its purpose is to block advertisements and third-party tracking cookies that do not respect the new Do Not Track (DNT) policy setting in a user’s web browser. Although some of the code for Privacy Badger is based on Adblock Plus, it only blocks those ads that come with trackers embedded.

As you browse the Web, Privacy Badger (PB) looks at any third party trackers that are loaded on a given site and determines whether they appear to be tracking you (e.g. by setting cookies that could be used for tracking or fingerprinting your browser).

If the same third party domain appears to be tracking you on three or more different websites, PB will conclude that the third party domain is a tracker and block future connections to it. Tracking is most common with DoubleClick (Google), Axicom, AddThis, Facebook, Spokeo, and ScorecardResearch.

For certain websites, if PB were to block an embedded domain entirely, it would break the site’s core functionality, in which case it blocks the domain from setting or receiving any cookies or ‘referer’ headers, but it allows the embedded content to load. Some advertisers, such as Google Maps and YouTube, cannot be blocked, but PB can adjust what is blocked, and social widgets can be replaced.

Advertising companies that engage in nonprofit consensual tracking of your Web browsing habits are widespread. They propose an opt-out that is, in reality, more of a “pretend not to track.” The new DNT policy flag, enabled by EFF, Disconnect, Medium, Mixpanel, Adblock, and DuckDuckGo, is a signal that the user wants to opt-out of online tracking and opt-in to DNT.

Ad blockers only block ads, not tracking, and are not always trustworthy. Incognito mode browsing is vulnerable and only untraceable between sessions. Targeted ads have no obligation to anonymity and you have no control over them; data can be stolen or sold, and these ads can be misused.

DoubleClick is a subsidiary of Google that develops and provides Internet ad serving services. Its clients include agencies, marketers, and publishers. DoubleClick is often linked with the controversy over spyware because browser HTTPS cookies are set to track users as they travel from website to website and record which commercial advertisements they view and select while browsing.

DoubleClick has been criticized for misleading users by offering an opt-out option that is insufficiently effective.

The National Security Agency (NSA) uses Google cookies to pinpoint targets for hacking, and piggy-backs on third-party cookies. The Diffie-Helllmann Key Exchange Protocol establishes a shared cryptographic “key” between two computers that makes it difficult for a third party, such as NSA, to spy on a conversation; however, it has its weaknesses.

The Digital Millennium Copyright Act (DMCA) is a U.S. copyright law that criminalizes production and dissemination of technology, devices, or services intended to circumvent measures (commonly known as digital rights management or DRM) that control access to copyrighted works. This act, unfortunately, is sometimes “interpreted” to sue innocent acts, such as the DMCA vs. Baby case.

Panopticlick is a free online tool by EFF that tests your browser with one click to see how unique it is based on the information it will share with sites it visits, and therefore how easily it can be identified by the owners of the websites you visit online.

Noah recommends we use the latest versions of our operating systems and recommended Tor as a (free) browser that enables anonymous communication. If you use Tor, you will not also need Privacy Badger. Always enter data on an encrypted website.

EFF relies on subscriptions and donations. For more information and to join the Electronic Frontier Foundation, go to EFF.org.
