Clean Your iPhone’s Camera Lens

Serious photographers take care of their lenses. The rest of us just stuff our iPhones into our pockets or purses and pay no attention to the fingerprints and grime they collect. If your iPhone’s camera lens is smudged, it will impact the quality of your photos. Take a few seconds to polish it with a microfiber cloth now and then, or, you know, simply wipe it with the edge of your T-shirt. Your photos will thank you.

  • Who cares about QR Codes?

    By now you’ve probably seen one of those odd-looking white squares with a bunch of smaller square dots that make up a random pattern inside–that’s a QR code. QR stands for “Quick Response,” and a QR code is a form of barcode, just like on the packaging of nearly everything you buy.

    Usually QR codes are used to store Web links–URLs–so an ad can display just the QR code instead an unwieldy and hard-to-type web address. But QR codes aren’t just for ads. They’ve appeared on business cards, in magazines and books, on coins and bills, and even on tombstones–any place it would be nice to help someone load a Web link into a smartphone but where there isn’t enough room for a URL or in situations where viewers won’t remember the URL later. And the links? They can display anything that can appear on the Web: text, photos, videos, games, and more.

    Only one built-in iPhone app can scan QR codes–the Wallet app in iOS 9–but it can scan only QR codes that are associated with Wallet passes, things like airline boarding passes, concert tickets, and iTunes gift cards. For QR codes that encode any other sort of data, Wallet shows an error. It would be nice if Apple would add general QR scanning capabilities to Wallet or the Camera app, but until that happens, you’ll need another app.
    There are numerous QR code scanning apps in the App Store, but if you need a recommendation, give TapMedia’s QR Reader for iPhone a try. It’s free with ads (remove them with a $1.99 in-app purchase), scans both QR codes and traditional barcodes on most commercial products, and displays the associated information within the app. It can even help you create your own QR codes.

    To use a QR code scanner, launch the app, allow it to access the camera when it asks, and then point it at the QR code. Good apps will scan nearly instantly, but if not, move the camera so the QR code is centered between the guides. If even that doesn’t work, move forward or back so the camera can focus on the centered code.

    Once the code has been scanned, the app will usually bring up an in-app Web browser to display whatever was encoded. For certain kinds of data, like books or grocery items, the app may go right to Amazon or a price comparison site. Good apps will also keep a record of sites you’ve scanned, so you can go back to them later, even if you can no longer scan the QR code.

    So download a QR code scanning app and keep an eye out for QR codes. Once you start looking, you’ll find them everywhere–it’s a modern-day treasure hunt!

  • Do you use iCloud for Safari?

    With all the news surrounding the government’s attempt to force Apple to write software that doesn’t exist to crack an iPhone, iCloud has been in the news, too! Do you use iCloud? Apple has some huge server farms to support this amazing technology and I thought it would be good to do a brief review of some of the features as they relate to Safari.

    iCloud has sort of settled to the back of my mind because it just does its thing in the background and serves up features that I take for granted. But this week, I ran into a dilemma that puzzled me for some time. I noticed that I had accidentally deleted one of my folders in my Safari favorites bar. These were important bookmarks and I needed them back. Well, like a good boy, I have a Time Machine backup and quickly went back in time and restored my Safari bookmarks from a time before I had deleted them. Good stuff, but when I went to look the next morning, the folder was gone again. This happened a few times with me going back in time to get the .plist file. Then I figured it out – I had Safari active in iCloud so my bookmarks were being synced in the cloud. So, every time I restored it, it would eventually be overwritten by iCloud. The solution? Really sort of simple, I turned off Safari in iCloud preferences and turned it back on, problem solved.

    Activating Safari in iCloud gives you some great tools. You can start browsing on your iPad and pick up seamlessly from your Mac or you iPhone. It syncs your bookmarks and tabs and if you also use iCloud Keychain it will remember all those passwords for the websites you visit. If you use the reading list function of Safari it will also keep those current across your devices.

    As with the other features of iCloud, the features only work if you are signed on with the same Apple ID on all of your devices. It won’t know that you are signed onto one AppleID with your Mac and another with your iPhone. Most common issues with iCloud come down to this simple issue. Apple has not made it easy to merge Apple IDs so at least for iCloud you should be consistently using the same Apple ID. Open the iCloud System Preference on your Mac and choose Safari to activate iCloud on your Mac or go to the iCloud Setting on your iPhone or iPad to activate.

    You can also access the Safari tabs that you have open on your Mac on your iPhone or iPad. It is a bit different looking on the iPhone or iPad. Open Safari on your iPhone or iPad and then tap the tabs icon. You will see all of your open Safari windows but if you scroll down at the bottom will be all the tabs open on your Mac and you can click on any of those to make it active.
