Apply Color Separation Effects to Your Images with Tintii Photo Filter
Tintii Photo Filter is a free and open source software which allows you to apply color separation effects to your images with just a few clicks. This saves you a lot of time without having to install or use some other software like PhotoShop.
The program will automatically separate the color profile of the loaded image into a handful of major hues. You can then select which one do you want to keep and which one you want to suppress. You just select which colors you want to keep and the rest will turn black and white. You can also stack multiple colors and also adjust the saturation and hue settings to make the effects more intense. There is no need for any complex tracing or masking. You can also preview the changes that you are going to make so you can decide before applying. This is good for both beginners as well as professionals.
The program is a freeware and a photoshop plugin is also available which will cost you money. The program is also open source and can run on both Windows and Linux machines.
