Thinking and practise, Channel maps.

Extracting the model fem the white background using channels. You can use channel maps to load other stuff. Their none destructive so we can always go back and edit them.


Need to look for the channel with the most contrast. In this case its the blue. Copy and re-name this channel.


Now we adjusted the levels… We want a even larger contrast between white and black.


We then used a hard black brush to block out the image. Switch the mode to overlay and reduce opacity from 100 to 300 percent to get all the grey whisky hairs. Use shortcut “x” on keyboard to switch to using a white brush.

Then use command alt and a click to select the channel then switch on original channels and turn off the new one.

Then click select then inverse and add a layer mask.

We can only see how good of a job we have done by adding a new background. I copied a sky background into photoshop. To tidy the image up firstly i deleted the layer mask so the image was back to normal.  I also needed to delete the mask channel. Then followed the previous steps of selecting the mask with the most contrast and duplicating it. Then adjusted the levels etc….

Before we add a layer mask second time round we can refine edge using the laser tool then clicking refine edge. I switched the background to black then modified the shift edge. Then adjust the feather slightly.

Change output to layer with layer mask. Modify even further by selecting layer mask and by painting on black with paintbrush tool. Opacity 30 and mode normal.
