The reason I dusted off the camera today was to photograph some diamond earrings we're donating to our local humane society. They're going to sell raffle tickets at their Puttin' On The Dogs event.
The reason I'm posting this is because I am liking my diamond photography and this was a good example. I would love to get @Bitter Jeweler to weigh in. Here was the process:
- Steam clean and use cotton gloves to place the earrings on a piece of white acrylic.
- The diamonds were nice and clean (1.10cttw, I-J/SI1), but the magnification from my macro lens was enough to show a carbon spot in the table. I angled them just slightly until they weren't apparent.
- Adjusted lighting until I had a nice mix of dark/light (3 lights and 3 bounce cards).
- Helicon Remote to take focus stack.
- Helicon Focus to process stack (Method B, Radius 8, Smoothing 4). Here they are before editing (cropped and resized):
- Then into Photoshop. Camera RAW filter was used to adjust the exposure, levels, etc.
- Using Quick Selection, I created a mask for the diamonds. Then added filters just to the diamonds:
- Unsharpen Mask: 100%, Rad 3.0px
- Smart Sharpen: 100%, Rad 1.5px, Reduce Noise 100%
Other than that, I whitened the acrylic a bit with a curves layer and used the healing brush to remove a couple pieces of dust.
