what's the difference with green screen?

It is all about what fabric it is made of and the tone of green. You are going to want a pretty bright green but not to bright. From the picture you put up it looks like you will be fine. Also the material, because you want it to be as flat as possible with no lines or wrinkles in the fabric.

The Best kind of material is a good thick cloth. That is one thing you want for sure! This is because if it is too thin then you will sometimes be able to see through it or it will wrinkle up a lot. I have actually even seen like a felt looking material used as green screen because it never gets wrinkles or shows fold creases. The only thing i could see wrong with this is if you had a really close up shot the background could look grainy.

Also the second thing that you are going to want to know is the proper way to light it. This is because your new green screen attempt will most likely be a failure (I know mine was) and that's perfectly ok! It is all trial and error. You are gonna be tearing open your new package and pulling out a fresh green screen slapping it on a wall and filming. Well, the thing is unless you wanna spend hours in editing you are SERIOUSLY gonna want to research how to light your green screen. The whole trick is to make sure the lighting is all even throughout the frame. Here is a diagram.

Now you notice how it says you are going to want to be 2 feet away from the actual green screen? MAKE SURE YOU DO THIS! If you stand to close to it you can get unwanted shadows. Now if you are doing an interview and you are low on space and you have to have the subject closer than 2 feet then that can be fixed with more lighting, but! If this isnt the case you are definetly going to want to have your subject 2 feet away. Next you will notice the 2 clamp lights just in front of where the camera is. Well that is important also because that is what is going to light the subject and not so much the green screen so those dont have to be heavy duty really. Also i know everyone doesnt have clamp lights but i think even like living room lights would work fine! Also it isnt included in the diagram but sometimes you will want a back light just in case it is stil un even then you can put this right above the subject (if you DO have clamps those really come in handy) but they are not needed. You can also position it below at the very foot of the green screen. Again, this is just to take out any extra shadows that the subject may be putting on the green screen. This however is just a simple way of lighting your green screen and is fine for you now, but if you ever get a bigger one you need to be aware that, that is when you need to by higher quality lights, clamp lights, etc. Once you are that level your lighting kit should be pretty high end. Here is a link to a spot that can show you some examples.
