Green screens or blue screens are used as backdrops in chroma key photography, which is a process that replaces a solid-colored background from behind the subject of a photo (or video) with a new background. When you watch the weather forecaster on TV standing in front of a map, or Spiderman climbing down a building, you, my friend, are seeing chroma key photography at work!
You may be wondering, “Why use a green screen or a blue screen?” Because separating a background from a human subject in a photo or video is much easier if the background is made of a solid color which is not found in human skin tones, like the colors green and blue. (Remember, we’re talking humans here, not Martians or Smurfs.) The practice of chroma keying can seem daunting at first, so be sure to read through this guide to green screens to get started on the right track.
Tools for Getting Started with Green Screens
Can a beginner really do this? Removing and replacing photo backgrounds does sound complicated, doesn’t it? Not to worry! With digital photography and software designed specifically for this purpose, you can be swapping backgrounds with the best of them in no time. Here’s what you’ll need to get started:
1. Digital camera. You’ve got one already, right?
2. A computer. Either a PC or a Mac is fine.
3. A cable to download images from camera to computer. (Duh.)
4. Chroma key photography software. As with most software, you’ll run into a lot of green screen programs that are only compatible with PCs. But there are some made for both types of operating systems. For example, the Green Screen Software by Savage is compatible with both PCs and Macs. 
5. Green screen background. There are many on the market, so before you buy, carefully consider how you’ll be using yours. For an occasional fun shot, or as a frequently used tool for your photography business? For studio shots only, or mostly for outdoor sessions? Here are the differences to consider:
- SIZE: For example, 5’ x 7’ for photographing individuals, or 10’ x 20’ for group shots or full-body pictures.
- PORTABLE vs. STATIONARY: a collapsible pop-up screen or a rolled-up backdrop.
- MATERIAL: If you’ve taken a look online at green screen backdrop options, you’ve no doubt seen them in several types of material.
- paper
- fabric (muslin, polyester)
- vinyl
- foam-backed
- paint (to color a wall in your studio)
Whatever you choose, stay away from glossy or shiny materials since one of the issues with chroma key photography is the bounce-back color from reflective backgrounds. (More about this later.)

6. Background stands: If you have a studio and have been using other backgrounds, you may already own a stand to hang backdrop rolls from. But if you don’t have a studio set up, or the money or space for background stands, look for one of the smaller, collapsible green screens that comes with hanging hooks or a portable stand.
7. Studio lighting: Getting the best possible contrast between your background and your model is key for chroma key work, so you’ll need a well-lit green screen. For outdoor shooting in brightly lit areas, you’ll probably be fine with natural light. But for indoor shots, you’ll need professional equipment.
8. Digital backgrounds: Here’s the fun part! Selecting a new photo background for your subject. Let’s say you want the look of a studio backdrop. You can select digital backgrounds that look just like muslin. Or if you prefer your subject in a more natural setting, look for digital backgrounds with trees, mountains, or waterfalls. For fun shots, there are backgrounds of famous landmarks, or you can put your subjects in a frame with a holiday greeting on it. The available choices seem to be endless! The Savage Photo Creator Kit comes with an extensive image library of 3,000+ digital backgrounds to choose from!
9. Depending on your project, you may need a green screen suit! Check out this helpful video to learn how to use one.
How to Green Screen: Steps for Completing Your First Project
Ready to get started? Here are the steps!
1) Set up your green screen background. If you’re using a portable stand, figure out how to stabilize it so it doesn’t flap in the breeze or move around as your model moves around.
2) Get the wrinkles out. Foam-backed screens are virtually wrinkle-free, but more costly. If you have opted for a fabric green screen, you can get rid of wrinkles by spraying it with water or a handheld steamer. Try to stretch it tight as it dries to reduce the lines that may cause shadows in your background.
3) Set up your lighting for the green screen. You need to light the screen separately from your subject, taking care that your lighting is even and doesn’t create shadows or hot spots. Chroma key software works best when the background has uniform color across its surface.

4) Select your digital background for the shot you are planning.
5) Set up your lighting for your subject. Study the direction of the light in the digital background you have selected for your new backdrop. Which way do the shadows fall? Try to mimic this angle of lighting on your model. Matching the intensity of light will also help make your composite photograph look much more realistic.
6) Position your subject. Avoid shadows falling on your green screen by putting some distance between model and screen. Experiment with your own lighting and subject until you don’t see any dark shadows on the backdrop. More distance from the screen will also cut down on any reflection you might get if green light bounces off the screen. This can help avoid an unpleasant other-worldly green glow around your model—unless perhaps you’re going for that look.
7) Keep the model fully in front of the green screen. Any part of the body or costume that doesn’t have the green screen background will have a different background which the chroma key software cannot remove. Knocking out that unwanted background on your own can be a long, frustrating process with your photo editing software. So, keep those arms and legs inside the screen, kids!
8) Download your image to your computer.
9) Select your photo, then follow the directions on your software. Easier said than done? Well, here’s a YouTube video that walks you through how to use the Green Screen Wizard software mentioned before. This particular program is adept at removing any creases or shadows on the backdrop. That would be a great feature if you’re just starting out with green screen photography.
Presto, change-o! You did it! Now, enjoy the result of your first try using green screen photography and digital backgrounds. Doesn’t it look great? And you thought you were just a beginner.
Hi
If I buy your software can I also add my own backgrounds for the green screen or can I only use the backgrounds that come with it ?
Hi Frankie, thanks for your question! Users can import their own jpgs into the software, in addition to using our image gallery. We hope this helps!
Hello! I was just wandering if a green screen can handle being put under water?
Hi Liam! Thanks for your question. We have a few different green screen materials and the two we think could work under water would be our Chroma Green Solid Muslin Backdrop or our Chroma Green Vinyl Backdrop.
What if the player is wearing a uniform that has green as part of the uniform?
Hi Jim, great question! In that case, we suggest using a blue screen. Check out more about green screens vs. blue screens here: https://savageuniversal.com/blog/green-screens-vs-blue-screens/. Hope this helps!
I’m brand new to green screens, I ordered a 9×13 green screen, of the 13′ height, how much should I use for the height and how much should I have on the floor ?
Hi Gary! If you’re working with people, you probably want the backdrop 8-10 feet tall in the back.
Thanks for the reply, I read places where the further away you stand from the green background the better, but at least 3 (or 4 feet ?) I think I read, that is why I wanted to not have the background height any higher than necessary so there would be more length on the floor. You said 8-10 feet tall, but would 7 feet tall still work okay ? That way I would have 6 feet on the floor and have room to walk some and still stay at least 3 feet away from the background. Thanks !
Hi Gary, as long as the backdrop is taller than your subject you should be okay!
Hi!! If I buy this software for my students can it be installed on more than one computer?

Hi Savage Report Team, I was wondering do a Green Screen work perfectly if I sit close to it or are should I have a distance between me and screen to get it? Im a Youtuber who make reaction and gaming videos, and every time I make a video, I see shadows with a lot of noise on the screen when I’m editing it.
Hi Terrance! The key to successful chroma key is lighting the backdrop evenly, to eliminate shadows. To do this, it is usually easier to create distance between the subject and background. We hope this helps!
can we use red screen also for changing the background
Hi Jai! Thank you for your question. Unfortunately no, red is most common in human skin tones and would cause interference with swapping the background. We recommend checking out our blog, Green Screens vs. Blue Screens (https://savageuniversal.com/blog/green-screens-vs-blue-screens/) to learn more!
Wonderful green screens video make idea share. So helpful to me. Thanks for share this.
Hi, I am mainly focusing on using the green screen indoors for portrait photography. However, I am planning to participate in an outdoor fair to promote my business. Do you think the natural lighting outdoors will make a difference on my subject for my portraits still using the green screen in the background?
Hi Hriaan! If the background is evenly lit and lit separate from your model, either natural light or artificial would work and as long as the surface is not reflective then the light can be spread evenly across the screen. We hope this helps!
Im seeing kits that look in the photos to be pretty much the same, a mix of a goalpost like stand for a backdrop, white, black and green backdrops. Some umbrella or softbox lights, bulbs, kit bag and a weighted above head soft box.
However Im seeing in Amazon or ebay etc kits of around £50 to £70 and others looking the same, muslin material etc that are priced around £500 to £700 +.
Frankly what is the difference and what kind of kits would be suitable for beginners for audition , video presenter for you tube, some basic effects and photos.
What do I really need and what don’t I to get started, so not gettign kit thats over priced that I will not need unless totally pro and Hollywood level but also is not a load of cak that falls apart and is useless, what is it that those in the know, know thats needed and whats a rip off.
Hi I am about to start making youtube videos with my kids and we wanted to know if we were to purchase your product would we be able to set up a green screen behind them and use images that match their topic of choice like for example if they were going to do a science experiment would we be able to set it up behind them so i could look like something dealing with science?

Hello, I have been working on photographing insects with plain black or white backgrounds. My trouble is sometimes i would like to change from one coloured background to the other. To avoid changing the backdrop could a greenscreen be used even if the subject is stand on the greenscreen?
What are the pros and cons of using (1) muslin (2) non-woven backdrops? I’m trying to find the perfect backdrop to use for piano videos.
Hi Summer, thanks for your great question! We have a couple blogs we’d recommend checking out:

Thank you for the beginner’s tips for working with a green screen. My husband wants to get one for his business for videos. I am sure this would help him with getting that set up!
Now I understand why I should use green and adjust my photos. Thank you for sharing this information with us. It was very helpful to me
Wonderful green screens video makes idea share. A beginner guide to the green screen is seriously helpful.
I need some advice about the green background. I have tried to keep that cloth in place but when I use fans to make a video the cloth tend to blow with the wind. What should I do to stop that from happening?. Without blowing fan the cloth seems fine though.
Hi Mariah, thanks for your question. We recommend using several additional clamps to secure the sides of the backdrop to your support stands to keep it taut.
Good to know lot of things. Thank you.
Is the “Tech Green” of your photography paper the recommended color for use as a green screen? I looked specifically for anything named “chroma” or similar, but that’s as close as I found.
Hi Mike, yes, we recommend our Tech Green Seamless Paper for chroma key work.
Thanks for sharing. Its so helpful.
