Another Idealscope question.

[Bluehammer]

Whiteflash has recently added some stones this past week. They are ACA and appear to be Classic Line according to the IS. My question is:

The IS images seem to have a lot of white showing especially in the table. I think this would indicate more contrast due to leakage, but it seems to be much more than I usually see on WF. Could these newer stones not be as tightly cut or is the extra white around the table (etc.) just a result of photography?

Here are some examples:

Thanks.

Here is one of the images slightly resized.
The white is where its spose to be and shows a kicken ACA classic pattern.

I assume from reading the answer from John Q on another post of mine that this picture was done with a new camera setup. It would probably show a brighter picture to contrast New Line and Classic Line better.

Just so BH.

We feel strongly about natural, real-world lighting so we use a 5000K (+/-270 CCFL) color-corrected daylight source in a controlled environment as a backlight. Our prior setup used a long-standing camera which eventually had to be replaced. The IS photo in your other thread was taken in that setup.

Details can be found in this thread - as well as discussion on the whole IS photo topic. https://www.pricescope.com/community/threads/standardizing-lighting-for-ideal-scope-reflector-type-photography.27251/

The new equipment is very cutting edge. It''s amazing what advances are occuring in photography, but I may never know our intimate details, since the photo team glares and gets itchy trigger fingers when anyone wanders into their ''sensitive'' area. Anyone know the type? I think they think they''d prefer to leave those ''rocks'' out and put the camera equipment into the vault at night.

Any chance of a re-shoot or would this be an overall waste of time? A purty picture is a purty picture and I recall a saying to "not blame your instrument".

All the very best diamonds leak a little light thru the table and stones like the one Storm posted - the plaer areas would represent about 10-12% leakage in the palest areas. The ideal-scope and our human sight / color processing doubles or triples its estimation of leakage.

That is a wonderful stone

I think I can make that happen Blue. If you don't mind - drop me an email or call me in the morning.
