I understand most of what was covered in the video. My question is this. I have a graphic (a JPEG of a head-silhouette) that is on a white background. When I put the JPEG on a colored background, the white area around the silhouette puts the head in a white box. Can I separate the head-silhouette from the rest of the JPEG so it, and it alone apear against the colored background?
That was very helpful. Thank you. I'll ask one more novice question. I would also like to have the silhouette (which is all black) to have a black outline, but be white inside of that. So, my plan was to copy the black-silhouette head to a second layer, then reduce it in size by about 2%-3%, recolor it to white and layer it on top of the black-silhouette. I'm not sure how to do the recoloring. In Paint, I just grab the bucket and click the head...done. How do I do it in PS?
If you have a selection and what to color it select the paint bucket. Also check out blend options like drop shadows. http://psd.tutsplus.com/articles/tools/photoshop-drop-shadows/
