    Diamond Photos

    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.

    Hi Eric,

    Why Radius 8 and smoothing 4?, i had no clue what the numbers do so i set mine to 1 and 1 which could be a mistake. here are two images i have taken with helicon remote and focus.

    editing done in lightroom.

    That was the default and it gave me the crispest photo stack for jewelry. I tried different combinations but couldn't find a better setting.

    It looks like some of your detail is getting washed out. Maybe try lowering your exposure when shooting, then use photoshop to brighten it back up?

    That's me over exposing in lightroom I think, the original photo is below with no adjustments
