Green Screen PPT

1. Green Screen
One way to travel without
leaving home…

2. Start with capturing an image against a green screen…the shadows DO
matter so lighting well (not like I’ve done here) does matter…

3. What will your background be? I have been longing to go back to the
isle of Capri off the coast of Italy…

4. Resize your images, both the foreground and background MUST match
in resolution and dimension.

5. I chose a resolution of 180 and not larger than 10 inches wide.

6. Before you begin, Command J to make a duplicate of your image.

7. Select the eyedropper
from the toolbar. Note
the selection default is
black and white.
Using the eyedropper,
click on an area of the
green screen that you
feel is the most
consistent. The
selection is now
displayed as that color.

8. From the select drop down menu, choose color range.

9. The color range display allows you to isolate the figure with a mask.
You can manipulate the opacity using the “fuzziness” slider. Notice
the shadows (my poor lighting job) in the background.

10. By selecting invert, you can see a smaller version and how the
background is affected.

11. Click ok. A moving crawl line appears around both the figure and the
outside edge of the image. This is the area your new background will
replace.

12. Click delete and the green screen is removed from the image on the
layer to the right.

13. Find your new background image and resize so it will be compatible
with the foreground image. Make sure “constrain proportions” has
been deselected to insure the images match exactly.

14. Voila! Off to Capri!

15. There is a second, fast and easy way of deleting the green screen if there are
fine details in the foreground image (hair, etc.) that gets rid of that “cut and
paste” look. Once you’ve sized both images, place the background behind
the foreground image - no need to use any of the selection tools…

16. Select the Background
Eraser Tool (hidden
behind the eraser
tool).

17. Make sure you’ve selected the color range with the Eyedropper Tool.

18. Select your desired
brush size, Sampling
Once, and
Discontiguous…

19. …making sure you are on the correct layer, place the crosshair on the area to
erase and click and drag.

20. Done!

21. What if I were suddenly
very, very small?
