Title: Deschutes Jasper Cabochon
Post by: freeformcabs on July 25, 2017, 08:09:08 PM
I am testing a new photo set up cause I plant to re-photo all my cabochons. What do you guys think of the image quality and color? There is no enhancment to this image except a crop. It was shot at 1600iso so it is a little grainy. And Running it on two different monitors shows almost a greenish hue on one screen, yet on another screen it looks dead on.

  I live in central Oregon and I believe your jasper tends to appear more like what is called Biggs jasper and is more sought after and pricier than the Deschutes which has more of a tan base color.
The cab does not appear to have been polished,perhaps it is just the lighting.

   Finished it is easily in the $40--50  range.     :headbang:

Shain, I see no green in the photo on my screen.  I could be wrong (probably), but it does look like blue Biggs to me.  Very nice cab!

What color is the background?  On my screen it appears yellowish-green and the stone seems dark and the pattern rather undefined.  Nice stone.

Colors appear accurate for many pieces of Deschutes I have, though when I zoom in it looks like it needed to be shot with more light (real grainy). I also see the background as yellow - if so, you might try a neutral gray instead. I find white backgrounds make darker cabs look even darker.

If you are shooting tripod mounted slow it down (longer exposure) so you can drop the grain from the iso.  Are you using daylight lighting, the yellow often comes from shooting with incandescent bulbs in the area.

Judging from the range of comments about this, I'm beginning to wonder if my screen is bonkers. 

I massaged the original image a bit in my photo editing program -- nothing major, just a white balance correction, size change and a little boost in exposure -- and this is the result.  It looks right on my screen with a white background, no graininess and better-defined detail in the stone.  In my estimation the white balance setting in the original image was wrong, but I'm not sure if we're all seeing the same thing.

Thanks for the insight guys.  I guess I should of posted it in the photography forum. (feel free to move if need be). Not looking for an ID, Thank you for your input though. Ive had this piece in my collection for almost 23 years and I know exactly what it is. (and It is also over 5 inches long)
The background is white, I will try a new one today(black or grey). I am using 9w LED that are 5000K(cool), and 800 lumens. I did not white balance the camera. I will the right background and more lighting should solve the problem. I will post a new shot when I change it up. Thanks again everyone.

   $50, I would buy a dozen....  even if it were only 3 inches long. Top quality Deschutes's and Biggs's are bringing top dollar today with jewelry designers and collectors. Yes, your color balance was off but the cabochon is excellent.

Here is the better photo at 100iso, harder lighting and faded black background.

That last photo is awesome. 
The background color on the first looked like a creme color and the stone didn't appear very polished...
but the last photo really shines ( :icon_sunny: )

Hiya' Shain.

That second photo shows you know the ins-and-outs of photography. That's a great shot of an awesome stone.

All monitors are different, for sure. There are calibration tools out there to help get true-color displays, but since most people won't ever bother to calibrate their monitors all we can do is produce the best image possible. I know the second shot of your Deschutes is an accurate representation because you've been looking at the stone for so many years, and the colors look right to me as judged against the Deschutes I've seen in hand.
