Getting started with Instagram for Android
Getting and taking photos
To get photos into Instagram, click on the camera/share button. You can either import photos from your Gallery or take a new one. By default, Instagram will use your phone's camera app, but you can also use Instagram's advanced camera. The advanced camera allows you to take photos without leaving the Instagram app and automatically crops the images to the Instagram format, which lets you skip the cropping step required when using an alternate camera app.
To enable the advanced camera, go to the Profile tab and click on the context menu in the upper right-hand corner (three vertical dots). Then, go to Camera Settings and check the box next to "Use Instagram's Advanced Camera." Keep in mind that the advanced camera does not work on some phones.
Once you've imported a photo or taken one (and cropped it), the editing screen will appear. From the editing screen, you can apply one of the 18 filters, add or remove borders, apply the Lux effect, or rotate the image.
Sharing and engaging with the Instagram community
After you've edited your photo, the next step is to upload it to your Instagram account. Tap the double-right bracket in the upper right-hand corner to get to the sharing screen. Just add a caption and hit the big green upload button. If you don't select any of the social networks, your photo will only upload to your Instagram account. If you decide later you want to delete your photo, just bring up the photo, then tap on the three horizontal dots below the photo and select Delete.
As Jaymar Cabebe noted in his review of Instagram for Android, Instagram's real appeal is the user community, not its camera or filters. To fully benefit from Instagram, you should engage the Instagram community by sharing photos, following users, commenting, and liking other users' photos.
You can search for people to follow from the Profile tab or look through the photos in the Popular tab (star icon) to find new people to follow. To like a photo, either click on the heart button located below the photo or simply double-tap on the photo. You can also use the comment button, to leave comments.
That's it. After you've had some time to build up a collection of some of your best Instagram photos, check out Sharon Vaknin's DIY post on how to create your own Instagram photo strips.
