Wondering how to alpha mask in photoshop?
Briefly, To apply this method of masking we have to see which channel gives the most contrast and for that we’ll have to use Chanel Palate. If the palate is the blue channel we simply make a duplicate copy of that channel and apply some level to that to increase the channel sufficiently. If it becomes necessary we can paint over the inner portion of the new channel with black color to make it completely black. Then we go to the next step where we inverse the channel to make the white to black and black to white. Then we copy the created and customized channel and paste it into the layer tab for making a new layer.
In this case, we can use the dodge and burn tools to make the edge portion more contrasting and in this way, it will help us to apply Alpha Channel with perfection (making the edge fur/hair more black for ease of use).
An advantage in this step is you can also apply the “color Decontaminate” feature from the Layer>Matting>Color Decontaminate of your menu. We have noticed that sometimes with this option we get an amazing result.
Before applying color decontaminate directly we should make a copy of the layer for safety. Because this is a destructive process. So, this was a brief discussion about Alpha Channel Masking to give you some idea about this cumbersome process. There is a renowned proverb that, one dollar saves means one dollar earned. And with us, you can expect to save up to 30% of your money. If you have any concerns or queries, please comment down below or send an email to discuss further.
