COLOR ACCURACY IN OUR
MINERAL PHOTOGRAPHS

People occasionally tell us that they think we take "the most beautiful crystal and fine mineral photos on the internet." While we enjoy the compliments, the real stars of the show are the minerals themselves - bright red rhodochrosite, canary yellow sulfur, emerald green fluorite, cornflower blue tanzanite, and so on. When we take photos, we are 100% focused on accurately capturing the true colors of these amazing minerals. So, here's the scoop on what we do to capture the correct color of each specimen in our photos.

CAMERA
Our team of professional photograpehrs take all of our photos, using a DSLR camera with a macro lens for most specimens, and a high quality zoom lens for our larger specimens. Before we shoot, we color calibrate our camera with a gray card for consistency and white balance.

LIGHTING
We light the specimens with special bulbs that put out light waves at 5000º Kelvin - about as close as you can get to the wavelength of average natural sunlight, which is 5400º Kelvin. Other lighting, such as incandescent and fluorescent lights, produces light at different wavelengths (such as 2000º K or 3000º K), which distort the true daylight color. These lights make mineral specimens appear to be different colors than they are in natural sunlight. In general, incandescent lighting exaggerates the yellows, while fluorescent lights exaggerate the blue ("cool" light tubes) or the reds (ordinary tubes).

SOFTWARE
After we've taken the photos, we adjust the resulting digital image using Photoshop and Lightroom software. This is necessary because even using 5000º lights, variations in the brightness of the light, the lens opening, and the shutter speed produce images which are different than what the eye perceives in full sunlight (too dark, too light, over-saturated, washed out, etc.).

MONITORS
Our monitors are regularly color-calibrated to professional red-green-blue (rgb) standards, ensuring that the colors we see on our monitors are as close to the "ideal" as possible. Then, if necessary, we make minor adjustments in Photoshop and Lightroom to bring the colors we are seeing on our monitors as close as possible to the perceived colors of the mineral specimen in full sunlight.

OUR GOAL: TO MAKE EVERY MINERAL SPECIMEN LOOK ITS BEST
We think of this as the equivalent to taking a portrait photo. Professional portrait photographers usually try to make their subject look their best, capturing an exact likeness in as flattering a light as possible (think of the movie star who wants to be photographed on his or her "good" side"). Similarly, we want the viewer to see each mineral specimen in its most flattering natural beauty. We do not use color exaggeration, distortion, or air brushing of blemishes to make a specimen look better than it is. If we’ve done our job well, our photos capture each specimen at its very best.

WHAT IF MY SPECIMEN DOESN'T LOOK AS GOOD AS THE PHOTOS?
If your specimen does not look as good in your display area as it does in our photos, the first thing to check is the lighting. If you are you looking at the specimen under incandescent or fluorescent light, that may be the source of the problem. We've had customers complain that the specimen they received is not the same color as the photos showed. When we suggest they look at it in the sunlight, they usually call back to tell us they've "seen the light".
Another common problem is the brightness of the lightning. Keep in mind that we photograph our specimens using plenty of bright light - again, to show them at their best. If you don't have bright, color-correct lighting for your mineral display, you may want to consider investing in a good lighting system. If you do, we think you'll be delighted to see your specimens in their "true colors" - perhaps for the first time!
