Easy GreenScreen Plugin for Photoshop

Other Thoughts and Considerations.

The Easy Green Screen, Plugin itself.
In my humble opinion, this plugin is far superior to most all commercial plugins available on the market today. With the only exception being; it only works with Green, Chroma-Key backdrops at this time. I understand Green/Blue Chroma-Key backgrounds are currently under development 🙂 This plugin is Freeware, but I would strongly encourage you to make a donation to the plugin developer. This will help to ensure it’s worth Damon Bell, time to continue development on this Outstanding Plugin!!

Hair and Clothing Color.
Blondes and Platinum Blondes are the most difficult situations you will have to deal with. Green eyes and clothing can cause issues, but its easy enough to go back to the Mask Layer and unmask any areas the plugin removes during the process. Simply click on the Black – Hide All mask, and using a white paint brush, paint it back in… 🙂

The Digital Backgrounds.
There are a zillion considerations you should be aware of when selecting a digital background images. We are only going to discuses a few here, you’ll get the hang of it as you go along. I hope to have a DVD available shortly of my Chroma-Key workshop, where we cover so much more then here.

Where to get the backgrounds; Well, shooting them yourself is a great excuse to get out and enjoy photography! E-Bay has several commercial suppliers, but just like anything from e-Bay you need to be careful what you are buying! Make sure you are purchasing backgrounds with the same or greater resolution then your base – Chroma-Key image.

Licensing Agreements on Digital Background images are another thing you need to pay attention too! Usually – the best, allow full commercial and privet usage rights once you apply your new top image. Not all licensing agreements are the same, know what you are buying! I would not recommend taking images off the Internet for several reasons. First the resolution is to low, we only want High Resolutions images for our purposes. Next it’s my understanding the photographer always retains the copyright (in America) until s/he sells or leases the image rights to you. For additional details on this, consult a competent Copyright Attorney in your area.

Selecting the proper background image is an art form in itself!! All of the tutorials I have read usually suggest you compose your image so that the feet are not in the final image. This certainly helps and may be something you would wish to follow in the beginning..

Well, on behalf of Kelly and myself I hope you have as much fun playing with this as we did shooting it!!



Recently Damon Bell, the Easy Green Screen Plugin developer dropped by to explain a few of the differences and to inform us all of the latest versions and features…

Thanks so much Damon, that really helps!!

Hey Dave,

First, great article on using Easy Green Screen. Thanks for posting it.
I just ran across this so I thought I’d reply to answer a few questions that people have (I am the developer of Easy Green Screen).

1. Yes, you may put a link for people to download EGS 2.2. That is perfectly fine. I removed the link from my website so I didn’t need to support 2 versions.
2. The reason for the changes to the extraction algorithm in version 3 are two fold.
First, EGS 2.2 did not do well for loose strands of hair. it would generally mask them out. The new method in version 3.3 / 3.4 works much better for getting hair detail, although it requires the user to tweak 3 different levels adjustments.
Second, if there were two different sources of green for the background, V 2.2 may not extract it well. EGS 2.2 extracts almost exclusively based on hue. This allows for it to be very aggressive to extract shadowed areas because the hue doesn’t change much between the lit and shadowed areas of the screen. However, if the hue varies in the background by more than 7 or 8 degrees, some areas won’t be extracted well. This become a problem in cases where multiple background sources are used.

For example, if a separate green floor was used together with a green chroma key backdrop. If the hue of the floor was not exactly the same as the backdrop then there can be extraction problems. EGS 2.2 will analyze the image and average the hues between the 2 background sources which becomes the target hue for extraction. So for example, if the BG hue is 120 and the floor hue is 140, then the target extraction hue would be 130 (assuming the floor and BG are equal sized areas). For this example, neither the floor or the BG would extract well. This problem was reported by several users who do full body shots and use a separate green floor together with a muslin backdrop.

3. EGS 4 is in development. The plan for the new version is to give the user a choice between the 2 different extraction algorithms. I don’t have an ETA for V 4 yet. It will be at least 3 or 4 months though.
