DGTouch provides Channel Masking Service to you

Channel Masking is referred to as Raster Masking and this technique is used for translucent, semi-translucent images when creating layers is difficult. Channel Masking is used to separate objects from their background or layer. This method is pixel-based rather than vector-based, but the technique used is different.

All the colored digital images contain three or four color channels; red, green, and blue or cyan, magenta, yellow and black. While isolating an image using channel masking an extra channel is created which contains the shape of the isolated object rather than a color. channel masking is often used to isolate objects with a lot of detail and is made by using the color channel with the most contrast.

If you want your images done with this method, you just have to add the instruction in the description job when you create a job at DGTouch.com. For channel masking creation, DGTouch will isolate your images using the selections and contrasts in color channels to upload your images in TIF or PSD format.
