Hi All,

I bought a green screen to help myself abstract my clients from the background and replace with digital ones but i'm finding i get this green cast over the skin and hair. I use soft boxes and tried many of tutorials on the net but none are giving me a good result. When i try to abstract hair i find this most frustrating and end up having to refine the edge to cut out the green but then i loose parts of the hair. I've been using colour selection so far as this method seems to be working the best but open to any other suggestions, what am i doing wrong?

go to the itunes store, and search for "dekepod" and "russell brown".

I'm pretty sure that the Deke McClelland podcasts had a very simple tutorial for removing the green, and the Russell Brown podcasts had a sequence of tutorials for extracting furry monsters from backgrounds.

Have you tried a masked hue/saturation adjustment layer or selective colour adjustment?
 
I would try selecting the area and using a Photo filter warming filter.....maybe a deep yellow to start on the hair........ not sure but worth a try
 
Greenscreen chroma is usually done for video.... you will probably get a better result for stills by just using black, white or silver background. However, there's some things you can do to improve the result if you are going to use greenscreen.

Int he pic above you are getting a lot of shadow on the greenscreen and also a lot of green is spilling onto your talent. The spill is from light reflecting off the green and onto your talent, which is something you want to avoid. The shadow is from not have a light behind your talent pointed at the greenscreen, and also the positioning.

For this to work you need an evenly lit greenscreen in the background and lighting that separates your subject from the green background.
 
perhaps sharing the way you did it would be helpful to another in need. otherwise We can close this thread to deter spam.
 
She is too close to the green screen. You need 6 feet between the subject and the screen or the color will bleed onto the subject. You also need to have zero shadows on the green screen or else it will be nightmare to "key out". Green is supposedly still the best compared to white or black because it is the farthest from skin color.
 
Never heard that before about the green being the best.. If you know what your doing you can remove anything from any background with little effort..
 
I have no doubt. Why go to the trouble if you don't have to. The whole purpose of chroma key is to make the background removal as simple as possible. A few key things in the setup of the photo can save time in Photoshop that could be spent else where.
 
Green and Blue are the best for chroma key (usually for video), but when you have lighting and distance issues causing the green to spill onto the subject it becomes a problem. You will not have that problem with white or black or silver and for stills they work great.
 
Thanks guys, I've spent a few hrs reading and speaking to a local guy about green screens and lets just say I now look at the green screen completely different now. I now see its all about lighting and the position of the subject its not as simple as placing someone in front of a green screen as the guy I bought the screen off said (grrr) Anyways thanks to Photoshop there is never a "cant do" its just spending time to research and playing around with different techniques I believe. What I did find that worked for my disaster project was the tutorial on www.rykerbeck.com this cleaned the green right up. Its obviously the hard way due to the way i took the shot but it did help me fix the problem which i shouldnt have in the future. Hope others find the tutorial usefull. bye for now

Again, i agree 100%...

Glad you got it sorted Glam!!
 
Hey Glamcreations how did you figure out a way to fix this. I have tried to put distance between my backround and subject, putting a light shooting back at the subject, that didn’t work so I tried putting the light on the green screen. Maybe this is just my case but I put one of my kids white bears on a chair and a light brown one on a chair. The white one is perfect (flawless) but the brown one has like a halo effect around the whole image. I tried emailing the support staff at fxhome but they have not responded. Any help on this would be much appreciated.
