My last few days have been spent taking photos of fruits, for a poster I have been working on for a site we are launching (all about that in about a week). Anyway, since I had to create the white box and learn how to use it, I thought I might as well share the knowledge.
How to make a white box or caja sin fin:
First you will need to gather you materials:
A large cardboard box
Sharpie or black marker
Tape – preferably packing tape
White tissue paper
Thick, large, white and matte piece of paper
Glass sheet and four small somethings to hold the glass up (I used shot glasses)
At least two (three better) lights/lamps with flexible or controllable heads
Three 60-100 watt, white-color light bulbs
A camera. Any will do, but manual settings and RAW quality will be helpful.
An object to photograph
Okay, once you have it all it is time to start. Begin by taping the back of the box with packing tape.
Then mark three sides of the box with your ruler and Sharpie. You are trying to get big holes in each side, but leave enough to have a structural border and attach the tissue paper. Aligning the ruler with the sides of the box and marking on the other side is the easiest way. Then follow your lines with your exacto knife, cutting three sides of the box.
After cutting the sides, cover them with tissue paper. It is important that you put the shiny part of the paper on the outside of the box. Remember that your tissue paper must not be too thick, so that light can come in, nor too thin because it needs to diffuse the light.
Now, you are almost done – building the box. Find your setting and surround your box with the lights. One on each side and an optional one coming from the top. Then lay your white matte piece of thick paper in the inside and tape it to the back, making sure there are not folds or shadows. Next, set up the four pieces of something that will hold up the piece of glass in a big square – one per corner. Lay the glass on top. Finally, set your tripod in front of the scene and set up your camera.
Now chose your object and start experimenting with the white balance, until the white of the background looks like the same white in the camera. Over exposing shots helps with this and with eliminating the background. After you have your shots, import them to Photoshop, where you can extract the white of the background and retain your object.
NOTE: If your object is white remember to use another color of background paper. The whole point of the background color is to create contrast so that you can separate the object from the background easier in Photoshop – and to reflect light and eliminate shadows.
Here are some of the results… after Photoshop off course.
