Extracting a Glass from a Photo
In one of my “Alpha Channel” vids I mentioned I’d cover this topic. Well, I finally got around to it. Turns out I needed to do this for a real-world situation. I was designing a website for a client and wound up needing to extract a glass from one photo and place it in another photo. Along the way I fell in love with Content Aware Scale, then just as quickly fell out of love. I’m so fickle.
At any rate, I cover the following topics:
- Color Range
- Alpha Channels (of course!)
- Content Aware Scaling (new in CS4)
- Faking a cast shadow (not a drop shadow)
- Brushing in opacity using the, er, Brush
- Faking specular highlights (no, really)
- Layers, Adjustment Layers, Layer Masks
There’s a lot of useful stuff here. I know it’s sorta long (a little over 40 minutes), but I promise everything I cover is stuff I do everyday in Photoshop. There is nothing esoteric here……just real-world Photoshopping!!
I know some folks have asked me to include the image files I use, but in this case I really can’t as they are stock images that the client purchased.
Please don’t hesitate to post a comment below if you feel inclined.

Looking with great interest to your extracting glass tutorial. Very well done.
A few remarks/questions:
- creating the reflection of the stem, isn't it better to not only copy it and turn it upside down, to flip sides. I noticed in the 100% opacity setting, that the right side (black) shows on the left of the reflection.
- Although you mentioned that the background distortion created by the Content Aware Scaling tool was fine, how would you actually repair this kind of distortions?
