All you need is the new photo app named poshlight. It's a surreal photo effects blender, designed to create nice photo effects directly from the phone.
If you don't have it already, grab it from iOS AppStore. It's a 1.99 paid app, but it's very powerful and feature rich, and inexpensive compared to similar apps such as photoshop touch.
This is the start screen of poshlight, all photos in your cameraroll are there. You can tap on any photo to start editing it. Or you can take a photo or select from albums.
Now we come to the editing screen...
Tap on the image thumbnail, the toolbar will appear. Tap on 'adjustment' button...
There are several professional photo adjustment tools here. Swipe to see more tools off the screen. Tap on 'zoom blur' button.
You instantly get the zoom blur effect applied! You can slide the slider to adjust the strength of the effect.
This is the final result, how does it look? Pretty cool and professional, right?
You can share to yours friends or save it with one tap!
Lets share to Instagram, poshlight has a builtin crop tool, so you can crop the photo or leave it original aspect ratio.
Instagram app will be opened and a few taps the cool zoom blur photo will be shared!
