iOS Tip 145 - Mark Up/ Sign Your Images in Email

In the built-in iOS email app - Mail - attaching images to messages is simple—hold a finger down in the message and when you get the pop-up menu, select Insert Photo or Video. In iOS 9, you don't even have the five-image limit anymore.

Better yet, it now includes the ability to annotate or mark up images. With the image inserted, hold your finger on top of it until the pop-up menu appears, then select Markup. Draw on the image with a number of colors, turn the drawings into recognized shapes, zoom in, add some text, or even throw in your signature.

iOS Tip 139 - Find Photos by Location

1 Summon Siri as usual by holding down the Home button or with Hey Siri
2 Say a phrase like “Show photos from (location)”
Siri will automatically launch the Photos app and sort pictures based on the location parameter you provided.
In the example shown in the screenshots, “Show me photos from East Lansing” displays a handful of images taken near that location.
In order to search your image collection with Siri like this, you’ll need iOS 9 or later on any device that supports the hardware, and you’ll need to have geolocation of your images enabled with a library of geotagged pictures. If you disabled GPS geotagging data within the iPhone Camera app then you won’t find this feature to be particularly useful unless you save other images to your device that are geotagged.

Siri isn’t the only way to search an image library by location on the iPhone and iPad however, and you can show pictures by location through the Photos app manually from the Albums view.

iOS Tip 101 - Siri Find Photo

Siri, gains two new superpowers in iOS 9: it can understand requests to display photosand videos based on time and location: "Siri find September 19th photos" and it can set contextual reminders. For instance, if you come across one of our #iOS tips while you’re supposed to be working, you can say, “Remind me about this tonight.” You can also ask Siri to remind you of something once you get in the car.

iOS Tip 86 - Show Photos on Maps

Being able to see where you've taken photos can be very helpful if you want an overview of which photos you've taken near certain locations. Previous iOS versions highlighted this feature very prominently, but with the advent of iOS 7 and iOS 8, this feature is a little more hidden. To see your photos on a map, try these steps:
1 Open the Photos app
2 Select the Photos tab
3 Locate a header above the photos for a particular date and location, and then tap the location
When you do this, it will show that collection of photos on a map. However, if you wish to see all of your photos for a particular year on a map, navigate back to the Years section, and tap a year header. When you do this, all the photos taken that year will be displayed on a map.

iOS Tip 80 - Photo Searching

iOS 8 gives you the ability to search for photos based on locations or dates. For example, you can search for “November” or “Sparty.” You use this feature by opening your Photos app then tap on All Photos, then tap on the magnifying glass icon at the top of the screen.

Use the keyboard to type in what you’re looking for.

iOS Tip 79 - Perfect Pictures

Turn on Auto HDR. It takes three photos taken at different exposures, and combines the best parts of each one. You can make sure your iPhone does this every time you take a photo by launching the camera, tapping HDR, and selecting Auto.

iOS Tip 76: Hide Your Photos

iOS 8 lets you hide photos from your camera roll. You can hide photos by opening a photo in the camera roll and pushing your finger down on it.
You will notice pop-up options that says “Copy” or “Hide.” When you tap on Hide, a message appears that says:”This photo will be hidden from Moments, Collections and Years but still visible in Albums.” Those photos will be hiddenunless you go to the “Camera Roll” or “My Photo Stream” folder under “Albums” in the Photos app.
If you want to unhide the photo from your camera roll, open it from the album that it is in and push your finger down on it until an “Unhide” option appears. Tap on “Unhide” and it will appear in the “Photos” streamagain.

Where's My iPhoto

BEFORE you upgrade your computer operating system to 10.10.3 - update your iPhoto to 9.6.1. iPhoto 9.6 or earlier is not compatible with the current version of Yosemite (10.10.3). After updating to the current version of Yosemite you’ll see Photos (not iPhoto) on your dock. Photos is Apples new photo applications and is replacing iPhoto; when you launch Photos you’ll be prompted to migrate your iPhoto library to the new Photos.

The migration might take a while, depending on the number of pictures you have. Photos will migrate all your pictures, albums, slideshows etc. The only concern you might have is available space on your hard drive as after the migration you’ll have both an iPhoto and Photo library. Once the migration is complete you can delete the iPhoto library - freeing up the space.

Buy Photos for Mac: A Take Control Crash Course

This course will help you decide whether to transition to Photos right away, walks you through importing photo libraries from iPhoto and Aperture, explains the Photos interface and how you can organize your images, gets you going with the editing tools, and assists you with copying photos to iOS devices and Apple TVs. It also shows you how to create books, cards, calendars, and slideshows.

Particularly helpful is the explanation of how Photos works with iCloud, including using iCloud Photo Library to create a centralized photo library for all your devices and sharing photos with friends and family via iCloud Photo Sharing. While we now think it’s safe to turn on iCloud Photo Library, beware that it may overwhelm your Internet connection.
