A DSLR camera can easily give you these kinds of images because of its big image sensors coupled with a wide lens selection. The law of physics gives limitations to the hardware that can be used on our mobile devices.
AfterFocus Is The Photography App You Really Need To Try
AfterFocus for Android and iPhone allows you to take DSLR-like images. Those blurry background photos are now in your hands. Select a photo you want and draw some lines to identify the focus and background and the application will do the magic. Selecting the focus area precisely will greatly improve the final images to look natural and professional.
AfterFocus does not only gives you the ability to create blurred background of photos from your phone, but it also comes with a bunch of naturally looking filters such as cross process filter that looks so natural. As a professional photographer, I love seeing bokeh on my photos. Photos with shallow depth of field won’t be complete without bokeh, and its maker must be kind enough to include a filter that does just that. Add bokeh to your already great shot.
