Signet Ring       ©2019 aoc46
Panasonic DC-GX9       5th place, 106 points
1/400s, f6.3, ISO 1600, 110mm, Aperture Priority, Center Weighted Average, no flash
 
Post-Processing: Merged .mp4 frames in focus stacking software. In image editor, adjusted WB and ring color, cropped, added vignette, resized.       Extra Info: Focus stack created from 80 ,mp4 frames.

My father was given this ring as a Christmas gift in 1932 and wore for the next nearly sixty years. The many tiny scratches that resulted show up only at this high magnification.

The backdrop is part of a 1777 nautical chart of Narragansett Bay (reproduction).

    Congratulations on 5th place, and thank you for the explanation re: the stacking process.

    Thanks, all, for the comments - much appreciated.

Note to SteveBee, A.N. Other, Lo:
I wonder if the soft focus you're seeing is not so much blur of the ring but of the reflected type, lines, etc., on the backdrop. If you're focused at some point on a reflecting surface, the virtual image you see there of something a distance away likely will be out of focus.

I'm using the same technique here that I described for my sixth place Open entry in Challenge #224 (and am too lazy to repeat). I suspect that the dichotomy of finding things in and out of focus at the same focal depth is confusing the camera's PostFocus algorithm, especially in deciding how many shots it needs to cover the range. For the much deeper spoon image in #224. it took only 20, whereas it wanted 80 for the smaller ring.

All that said, I'd agree that even if the subject really is in focus, if it looks blurry, that's still a problem. The only solution I can see just now is to avoid focus-stacking shiny objects, at least with this technique.

    Great image. The subject, light, focus, background all fantastic.

    An impressive shot. I particularly like how much you've personally influenced the look of this shot, from the image stacking, to the lighting, to the choice of the map as a background, which adds a whole other dimension. Anyone can take a picture of an intrinsically attractive object and thus create an attractive photograph, but you've gone way beyond that here.

    Interesting thing. In my favorites.

    Great looking ring and the map is a nice touch.

I've done a bit of focus stacking myself and I'm a bit confused by your result. You seem to have three zones of focus with OOF areas in-between. I would have thought you cold have got the whole ring in focus with 80 steps. Maybe they were set to close together? The gold colour has bled out from the ring on the top left and is missing underneath the shield. What software do you use?

    Despite the amazing detail in most of the ring, parts of it seem a bit blurred. What a wonderful keepsake. The nautical background was a great choice.

    I like the patina on the ring as it certainly adds character. I also like the idea of the background. Definitely in my favs.

    In my favorites. The nautical chart is a nice touch. Personally, I wouldn't shoot a still subject in lowlight at ISO 1600 and 1/400s. I assume you used the in-camera mode for stacking which I have found doesn't work all the well for closeups. As you can see, the entire ring is still not in focus. The lighting looks like it is from directly above which causes the dark shadows on the front of the ring. These shadows could be lifted a bit in post.
