My first review is on Instagram. Instagram is a photo editing and sharing app with a social media aspect, too. You can make some areas sharper and other areas more blurry, or change the color, saturation, contrast, shadows, highlights, or warmth. Instagram is my favorite photo editing app because it combines all the aspect of photo editing into one simple. easy-to-use interface.
My second review is on BeFunky.com. Be Funky is a free photo editing online app in which you can change all of the typical settings, such as contrast, brightness, etc. but you can also use a brush tool to apply the settings to only certain areas, which makes it my favorite online photo app by far.
