Preserving jewelry highlights and fire

Post by Jerry-and-Lois »

Hi there -

New to HF, as well as focus stacking.

I have diamond ring with a large center stone that I shot. My lighting is quite complex, with multiple fixtures.

I shot 5 different images, each producing a unique flash/fire from the stone. Variance was accomplished by enabling or moving a single light, taking a shot, moving the light slight to visually end up with a different set of flash/fire hotspots and taking a new shot. Repeat.

At the end I have some 5 different images, without moving camera or ring. Said differently,
image #1, has fire in the NE corner.
image #2 has fire in the center
image #3 has fire in the both the SE and SW corners,
etc.

None of the hotspots overlap or interfere/conflict with each other.

When I combine the raw NEFs using method 'C', not all the highlights survive. Some are partially washed out, even if they don't overlap at all with fire/highlights in any of the other images.

I'm trying to conglomerate the best of all worlds to maximize the fire/sizzle from the stone.

Because some of these highlights are faded out, I need to understand why, and how to preserve these, rather than let them disappear.

Can anyone offer insights on preserving highlights/fire/sizzle points?

thank you so much.

You need to use a flash and a bounce card to get the fire. I cut gemstones and it took me a while to figure that out. lol

Thanks for replying Badoldfatman (funny user name).

In my original post, I already have plenty of fire. In fact, an abundance - I created a lighting system that creates this easily.

My question isn't how to create the fire, but as I wrote below - if I have 5 images each with fire that's unique; i.e. fire in each shot is completely different, how to use HF to combine all the shots AND combine all the fire from each shot.

Thanks,

That's a complex task. First of all, we'd recommend using exposure compensation (of at least -3) in order to ensure the hotspots fall within the dynamic range. Secondly, we'd recommend using method B as it does not alter colors on the hotspot borders. And also we can recommend using retouching tools HF provides in order to preserve or remove hotspots.

Thank you, Catherine.

With one piece I shot, I ended up simply using HF to create a stack where all the images were sized to fit, as I also did some manual focus stacking.

When time allows, I would greatly love to show you both the before and after shots, and then see your suggestions on how to improve.

Best wishes,
Jerry
