You can open photographs already saved on your phone or tablet or take a new picture to work with. Snapseed offers a wide range of photo processing options ranging from basic corrections (straighten, rotate, crop, etc) to more advanced processing (brightness, ambiance, contrast, saturation, shadows, and warmth) and fun filters (black and white, vintage, HDR, grunge, tilt-shift, frames, and others). Whenever necessary, I have tried to make clear if a feature is only available as an add-on.Īpps for Processing Photographs - general Snapseed (available free for Android and free iPhones and iPads) is by Nik software who were recently bought by Google who then offered the app for free across platforms. Many of these apps are free but offer in-app purchasing options. For ease, I've broken this post-processing post into two sections: general apps for processing photographs (those with a lot of options) and specialized apps for processing photographs (those geared toward doing a specific thing very well).
