Chris asks: Is there a way to remove the background from the images of dragonfly wings?  I want to move the dragonflies onto different backgrounds but can't get rid of that part of the original background seen through the wings which are translucent and reveal whatever is behind them. I guess this would be similar to removing the background from the image of a glass bottle.

Answer: You're right about the glass bottle. You'll need to use the Extract filter along with the Force Foreground option. You can find information about this in the extraction article I wrote for PEI. Click here to download the PDF (5 pages 136K).
