Digital Photography and opal

“stone looks bigger in the photo than in real life” This is because a 10mm stone will show in the eBay item listing photo as a 100mm stone on an average size laptop screen. Please check in the “item specifics” section for the actual dimensions of all listed items.

It is difficult to achieve total accuracy in representing opal with digital photography for the following reasons;

The human eye sees things slightly differently to the digital camera because of the different mechanisms of how they register light. Each person’s eyes see a little differently to the next persons eyes. Many computer screens are manufactured and calibrated a little differently to each other. Example; a LED screen will have alot more contrast than a Laptop Screen. The opal colours and patterns seen are a result of a complex combination of refraction, diffraction, diffusion and reflection of light from the opal structure. When an opal is viewed with different light sources and different light intensities the effect of the stone can change a little from one light source to the other. The total combination of these facts means there will be some degree of inaccuracy when representing opal with digital photography. To compensate for these factors I like to list items with still photos and a movie with all care and techniques taken to represent the stone as accurately as possible.
