Black & White meets the Channel Mixer

In this movie I want to give you a sense for how you can combine black and…white along with the Channel Mixer in order to take advantage of the best of both features.…So here we are looking at that Infrared effect that we created a few movies back…using the Channel Mixer, and as you may recall we had posterization problems,…and I didn't even address all of them.…If you look closely in the upper left-hand corner of the image, you'll see…that there's more posterization in the background, and we have some weird…highlight details along the top of the younger woman's hair.…

So I am going to go ahead and zoom out, and I am also going to throw away this…layer of Gaussian Blur because we are not going to need it, we are going to mask…those posterized areas away.…So I will right click on the word Smart Filters and choose Clear Smart Filters,…and then given that we no longer need the Smart Object, I'll right click…inside the image window with the Rectangular Marquee tool, and I'll choose…Rasterize Smart Object.…
