It is extremely important to accurately capture the indigo colour of denim when creating a 3D prototype of your garment. However, the quality of the 3D scan highly depends on what kind of tools you are using. The following guide can help you to get virtualise your fabrics more efficiently without breaking bank.

To get you started on how to create your denim shimmer views, let us go over some things you will need:


INDIKON Equipment

  1. Denim Material (the scanning area is about 1.1 x 0.6 meters)
  2. Printed Bandicoot Chart
  3. Handled Camera with a prime lens and external flash
  4. Patience and time for a prior training

Prime lens is a fixed focal length photographic lens typically with a maximum aperture from f2.8 to f1.2.

Here is the manual we have prepared for you, and it will take about 5 minutes to repeat all these steps after thoroughly learning them:

1. Print the Bandicoot Chart

  1. Open the attached document
  2. In the printing settings opt: High Quality and Borderless
  3. Print out the Chart and Cut out the rectangular shape in the middle

Things you should keep in mind:

  1. Use matte A4 paper for your print: try avoiding shiny paper
  2. Use an inkjet printer: laser prints can be too glossy
  3. Preference is given to a heavier paper stocks (A4 is good too)

2. Check your camera

  1. Use DSLR camera or mirrorless camera with at least 24 megapixels (you can always surf the web for specifications)
  2. Make sure that your camera has a prime lens (has a fixed focal length that does not zoom)
  3. Get an external flash like Speedlight or Speedlite, that can be placed on the top of the camera

3. Set up your camera and flash

After checking your camera model, you have to manually apply following settings:

4. Prepare for the scanning

How to scan your fabrics yourself

At this stage, place your denim on the floor and make sure to leave about 1-2 metre of clear space around it. Put the printed chart on the top of the material and take a test flash picture directly from above of the chart.

Now, review the test flash picture by the following criteria:

  1. The exposure is as bright as possible, but without clipping any pixels
  2. White parts of the chart and any bright reflections are not over-saturated
  3. You can adjust the exposure by changing the flash power and retake the image to test it

Tips for a test flash image:

  1. The material and the chart should not be moved while during the process
  2. A room with normal or dim lighting is the best, avoid direct sunlight

Other Remarks:

  1. You can use phone or compact camera as well, just make sure that your device can save photos in RAW format, and can be set to a manual exposure and manual flash power. Although, we strongly advice you to use DSLR or mirrorless lenses as they usually have a higher quality of scans.
  2. It is recommended to use a prime lens, which is a lens with a fixed focal length (no zoom). It produces a better quality and avoids change in zoom during scanning process. However, if you have an access only to zoom cameras, you can still scan. Just make sure that zoom does not change during scanning.
  3. We recommend using an external flash like Nikon Speedlight, a Canon Speedlite, or any similar flash from other companies and third-party suppliers.
  4. If you need a chart of a different size (A5, A4, A3, A2, A1) they are available for a print out. Make sure to contact us and book a demo.
