Chromakey green values

I purchased a 5x7 collapsible chromakey green backdrop and am having the hardest time with it. Come to find out that it is not a true chromakey green (from other articles I have read). The software I am using does not recognize it much because of the color. Green Wizard Pro support told me the RGB values their software recognizes and I go into replace color and put in the values and that messes things up even more for their software. So I use the color values from a muslin green screen I have (from previous shoots) but the green looks nothing like the image I took the values from. Why is it when I put in the RGB values of one screen color into another they look nothing alike but all have the same values. I am thinking of selling it because I cannot get anything to work right. So what should the RGB values be of a true chromakey green background and when I buy a collapsible one how am I to know it is a true color that will work. The other softare I am using is the easygreenscreenn plugin and the author said it is not a true green for his software to work with.

An image is always helpful, & I'm wondering how evenly the light on the backdrop is? These might help:

Using a Green Screen Backdrop. Good or Bad?

Green Screen Product Photography?

My chromakey green muslin 10x20 I have no problem with at all. I got the collapsible so when I go into peoples homes or on location I can do a few green screen shots there. I am not lighting the background separately (not much room in peoples homes or trailers) and plus, I was told NOT to light it separately by the makers of Green Wizard Pro, so it is just lit by the bouncing flash I do..here is a sample image. Had 2 vivitar 283's bouncing off the walls,ceiling behind me. I have used 3 studio strobes with my muslin (still not using a separate light for the background) with no problems or even 2 strobes in big buildings and schools...but this collapsible is darker so I am at a loss. I have tried the replace color feature in CS6 and brightened the green up to 255 value as I have read before but that 255 is brighter than some other 255 green backgrounds.
Is there a true setting I can brighten it up to or should I just send it back because it is too dark of a green.

Your keying software does not permit you to select the key and the range of luma+chroma around that key? Seems that that is part of the problem.

Ok..what software would you recommend? I use Green Wizard Pro and the free photoshop plugin of the easy green screen. I can work with spill with those with no problem but keying out the green is automatic..I have no control over the ranges, seems like all that is built in. Even the pro version of easygreenscreen doesn't let you into the range part..so what software would you recommend?
On those software I just click a button and it processes automatically and gives me the result..the only thing I can do is work with any spill which is easy but that is all I can do. On the easy green screen site, I read the info about their pro version and it says it will handle ranges from 70 to 280 automatically and has all kinds of pictures of what it can handle. I downloaded the demo version and trying to extract all this automatically was a disaster..no reply yet from the makers of both programs.

I'm afraid the only keying I've done is in After Effects, using plug-ins Keylight and Magic Bullet Colorista II. That probably does not help you at all, but they are very versatile keyers and matte extractors.

I know that OnOne makes a product called Perfect Mask - I have never used it, but I know people who have great success with it. It is a plug-in for Lightroom, Photoshop and Aperture as well as a stand-alone app. It would be more versatile than a dedicated green key extractor. I do not know if it handles spill.

Oh wow..I love it..I'll check it out and I'll check out AFter Effects also. Anything has got to be better. I tried this evening Vertus Fluid Mask and it isn't as easy to blend hair and removing spill from hair as the video says..
thanks for your replies.

Check out Photokey 5 at http://******/hNJGT. It's a very versatile green screen program. I haven't tried it to much yet but it has some really great features.

Love Perfect Mask. Thank you.

I like the features, just took a little look at it and tried it..but I see no place for edge smoothing or feathering and the spill removal doesn't work all the way..moved the slider all the way over and I still have spill and the edges of the people are so crisp, no feathering or smoothing..people can tell it was a cutout. Perfect Mask is a lot better. Green Wizard Pro at least has a feature to go over the edges and it smooths them and just paint over the hair and all spill is gone.

Right on - post an example here so we can all see how it works.

Hi Shooting. Thanks for the feedback. I have both Perfect Mask and PhotoKey 5 but haven't had a chance to really dig through them. One thing that the On-One seems to lack is any form of automation or batch processing. it seems more oriented to non-green screen type images as opposed to standard green screen background replacement purposes. I may be speaking through my hat though so I appreciate your feedback having used Perfect Mask more than I have.

If you want batch processing then Green Wizard Pro has a great batch processing part. Trouble with it is if you have any green spill or need any adjustments then you are up the creek without a paddle but if all is ok, it is great for batch processing and it does have a demo for you to try.

Photokey 5 is also very suited to batch processing for shooting green screen at events.

Does it do good at extracting all the green automatically, even the spill on the hair?

The few I tried needed extensive green from hair edges removed because it was not good enough on it's own to do it automatically in batch mode.
