Step 1: Take or Choose a Photo

When the app opens, tap the Camera button to take a picture, or tap the Photo Library button to open a picture you took earlier.

Step 2: Zoom In

A dashed rectangle outlines the photo, and you specify where and how far to zoom by dragging any of the square handles to resize the rectangle, and dragging from the middle of the rectangle to move it. To preview the zoomed image, tap the + magnifying glass.

Step 3: Save or Share the Photo

Tap the arrow button found in the lower right to save or share the zoomed image.

The i button is used to view these instructions and to change settings.

Tap the magnifying glass icons to zoom in and out again as needed to refine your zoom selection. As you adjust the zoom rectangle, a three by three grid is displayed to assist with your image composition. By default, the aspect ratio of the original image is maintained, but that can be changed with the Aspect Ratio setting.

Tap the landscape/portrait orientation button to change the orientation of the zoom rectangle.

Tap the arrow icon whenever you want to save or share your photo, or shoot or edit another photo. Sharing options include email, uploading to Facebook or Twitter, sending to another app, or copying to the clipboard. When you save or share the photo, the outlined portion of the image will be saved according to your resolution settings. When saving, a new copy of the image is always created, allowing you to easily save multiple versions of the same image at different zoom levels. Note that only the outlined portion is used, whether you have previewed the zoom with the magnifying glass or not, so if you want to save the entire, unzoomed photo, save it before you adjust the zoom rectangle, and if you want to automatically save an unzoomed, full resolution version of every photo you shoot with the app, turn on the AutoSave setting.

Settings

You can count on getting good results with the default settings, but there may be times you want to do something different. You can easily restore the original settings by tapping the Defaults button.

Instructions displays the instructions you are currently viewing.

Startup Help refers to the instructions that may be displayed inside the zoom rectangle. You can turn this off when it is no longer helpful.

Aspect Ratio determines how the zoom rectangle is constrained. The default is the aspect ratio of the original photo. If you select Any, the rectangle will be unconstrained, allowing you to move the rectangle handles freely. Or you can choose from other common aspect ratios.

Save Resolution and Share Resolution: These settings determine the resolution of your saved and shared images. You can specify that High, Medium, or Low resolution is always used, or you can choose to be asked about resolution each time you save or share an image. In that case, when you are asked, you will have the additional option of specifying a custom resolution, which may be higher or lower than the original image resolution (you can scale down or up, to a maximum of 6000 x 6000).
