Flake is a lightweight application, just as its name suggests, that has the ability to simulate the long exposure photography.
This tool is wrapped in a simple and intuitive-to-use interface and allows the user to create stunning images in just a couple of seconds. Flake recognizes JPEG and PNG images, while the result is saved in the second format. Besides joining hundreds of photos, Flake can perform some effect adjustments, such as vanishing the on motion objects or removing noises.
Flake allows you to operate in two different modes, depending on your skills and preferences. In this manner, you can choose to apply a simple editing operation(where you can only calculate the deviation) or reference(adjust the thresholds, choose a reference image and so on).
Although is a pity that Flake doesn't offer too many adjustment possibilities, based on its price(which is zero), its accuracy cannot be questioned.
All in all, Flake is a simple and efficient application for applying long exposure effects on your images.
