BlendCamera is a free Android application developed by Shan Zhong, designed to help you create amazing double exposure photographs. With this app, you can superimpose pictures with greater accuracy and create special effects like the "twin" and the "city reflection".

One of the most impressive features of BlendCamera is the unlimited overlay, which allows you to overlay your pictures as many times as you want, giving you endless possibilities to explore. Additionally, the app offers multiple overlay modes, such as translucent, soft light, color filter, multiply, brightness, color deepen, color dodge, color difference, blurry, and more.

The brightness transparency option lets you select either bright transparent or dark transparent, while the transparency adjustment feature gives you much greater control when overlaying pictures. You can manually control transparency through a scroll bar, allowing you to achieve the perfect balance between the two images.

Overall, BlendCamera is an excellent application for those who want to unleash their creativity and become professional photographers. With its one-click color filter and the ability to share your creations on social media platforms like Instagram, Facebook, Twitter, Sina Microblog, WeChat, and more, BlendCamera is a must-have for anyone interested in photography.
