SDI has produced a wide variety of products for dentists since 1972. It is an Australian company that develops, manufactures and sells its product all over the world. I am very happy about photographing for them during these last 3 years. This project was quite different and quite special.

This project objective was to show the colour and the amount of transparency of small samples of the composites as accurately as possible. Each small sample of the product was 0.5mm thicker than the previous one. When placed side-by-side, the dentists will be able to identify which composite and the thickness required to create the desired cover and effect.

To achieve we have to have a high level of control of the light intensity and colour. This was done by keeping all lights positions and power absolutely locked during all 3 days and monitoring with a photometer that the values are what we need them to be. All our cameras, monitors and printers are calibrated (colour management studio) and our wide-gamut displays show accurately the colours (>98%).

In addition to positioning and controlling the lights very precisely, I had to develop a method to photograph all these 240 very small 7x10 mm material samples in the same way and over the same background. I printed a few cards with the SDI logo and a line that were used as the background.

To position each of the 240 small plates, always in the same position, I used a few pins stuck on a baseboard. All I need to do is to make sure that the plates touch the pins. Easy to say but not so easy to do. It took me almost 3 days to capture all the images.

When you are working on extremes such as super-macro photography, even the smallest change in the position of the camera or floor vibrations would affect the image and focus. I placed an extra floor and weights to support the tripod and reduce vibrations. Even the camera shooting had to be done by remote control to reduce vibrations.

After capturing all images, I retouched each one manually removing surface scratches and dust spots. I took special care to maintain the original colour. No individual adjustments on colour tone, saturation, contrast and luminosity were done. If one global adjustment was applied, it was also applied on the same proportion to all images. So, when you compare side-by-side, the only variable is the thickness of the material.

After retouching, I create composites (use of multiple images) based on SDI's specs. In this case it was a grid of images side-by-side as you can see here.

In order to deliver the files ready to print, I printed them on a variety of paper and inspected them with the specialist dentist to ensure we achieved the precise colour and representation of the transparency on each of the composites.
