It's a free app, as well, meaning you can test it out before upgrading, or save it to use only when you need the extra security that your images will be perfect. Pentax Optio Mx4 Manual is designed to automatically detect and swap faces in images stored on your device. The app works in many regards, but its facial recognition technology feels dated and often inaccurate, and there is no way to know which images it will work with and which ones it won't. As a result, there is quite a bit of trial and error, and because the process is automated, you can't change how the images are swapped. When you start Pentax Optio Mx4 Manual for the first time, you can choose an image from your photo library or take a new one. Like most face-swapping apps, it really only works well if you have two subjects directly facing the camera in even lighting. Side shots, different shaped faces, and awkward poses often lead to distorted images or the app will fail completely, not allowing you to do the swap. This is a limitation of the technology, but without an option to see when it will happen or the ability to manually mark faces that similar apps offer, it can be frustrating to get the right image to work. When the app does work, however, the effect is fun and the images are rendered quickly. It manages to blur lines enough that the faces blend nicely into the other

person. The effect is at times jarring, occasionally hilarious, and generally well presented, but again only when the original photo is the right size, distance, and shape, and in the right lighting. If you are interested in testing a free face-swapping app, though, this is a decent one to start with as long as you're willing to find the right images to work with. ShapPix is supposed to be an alternative social network to share images on your iPhone, but there are a number of issues here that keep it from being a viable option for

most users. From the overly long setup process and convoluted interface to the lack of direct interaction you have with other users, it can be frustrating in many instances. The first problems we encountered were in setting up ShapPix. Technically this works well, but the sign-up process requires quite a bit of information. You must supply a profile photo, as well as home country and other information that is unnecessary to share. The lack of built-in privacy functions in the free version means this information is out there for anyone to see, as well -- an issue for those that prefer to share anonymously. Nothing is stopping you from using fake information, of course, but it's still a lot to sort through on the first use. Next you can start sharing photos, taking them from your library or snapping new ones and saving them to the service. There is no clear way to connect with specific users, though there are following options. Buttons are often non-responsive on first tap, images are occasionally hidden behind other menus, and it's impossible to actually search for other photos; you can explore o
