Nova Scotian Agate
Photographs by Chris Sheppard
Cape Blomidon, Nova Scotia
Without exception these mineral detail photographs were made with a Nikkor 40mm micro lens using my 24.2 MP Nikon DSLR attached to a Manfrotto tripod system. Specimens were housed in a diffused full spectrum light box. All of the photographs were “cropped” and framed in camera often using a vari-angle Live View to fine tune composition. The unpolished surfaces of some specimens were given a thin coat of mineral oil. Using mirror lock-up and a cable shutter to avoid minute camera shake I shoot a RAW image that holds all of the information captured in 14 – bit channels per colour. I use Adobe RGB colour space and process my RAW files using Adobe Camera RAW and convert them into jpegs using Photoshop Elements (A popular editing software). All photographers have to convert and process RAW images based on their own personal taste and preferences. RAW processing gives you complete creative control including custom white balance. I personally try to achieve the incredible colours you would see if the specimen was wet with salt water on a cloudy day!
Because of the sensitivity of the macro photography I may on occasion need to digitally remove a fine piece of lint or dust invisible to my eye at the time of exposure or soften a scratch left from the diamond blade used to cut the agate in postproduction. All of these agates were cut using a diamond slab saw that may leave scuffs and scratches that can distract from the image as a whole, especially when they are blown up for printing. Some of the agates have never been polished so a thin layer of mineral oil is applied to replicate a polish. Even without a polish the cut agate has a highly reflective surface when wet and shows every imperfection. The fractures occur naturally and become part of the composition.
