Good photography is critical to the success of Green screen products, here are a few general pointers when setting up your green screen environment.
The general rule of thumb is the more controlled the environment the better, particularly with regard to the lighting. This is difficult in a retail environment but every effort should be made to find a dark corner or separate room which is more conducive to green screen photography.
The goal is to make sure that the chromakey screen is lit evenly across, with no hot spots or shadows.
The image below shows the Hex tone of green #53d142 that the Image Remove Green Screen config option is looking for (with a 20% tolerance).
Here's an example of a good green screen photo with an evenly-lit green screen:
Here are several examples of poor green screen photos:
The hot spots and shadows mean that the end result is not good enough quality to print on a product.
The image below shows light sources in an uncontrolled environment which could potentially influence the result of the photography:
Here are a few general pointers to help you improve your green screen photos in a retail environment:
1. LIGHTING: Ensure that the chromakey screen is lit evenly across, with no hot spots or shadows
- Where possible locate the green screen in a small, separate room where the lighting can be controlled.
- If not possible and working on an open floor, erect some black sheeting either side of the green screen to create a kind of booth or tunnel, this will help to eliminate some of the natural light coming in from any windows.
- If the floor is glossy, put some kind of carpet or sheeting on the floor in front of the green screen to eliminate the reflected light.
- See if it's possible to turn off all artificial / ceiling lights in the direct vicinity of the green screen.
- Make the green screen material as taut as possible - rippling will introduce shadows.
- Make sure that the model is far enough away so that they do not cast shadows on the chromakey screen
2. Don't use shiny props
3. Remove glasses and reflective jewelery
3. If possible make sure that long/loose hair is tied back
4. Ensure the model is not wearing green as this is obviously not going to work.
5. Make sure there is no movement by the model
6. Make sure that no part of the model passes the extent of the green screen eg: a hand
