That being said, at such high zoom, I am sure it would face up nicely. Out of curiosity, do you know the depth of that stone? It appears to have a fisheye.

In the first picture one side of the stone is getting more light than the rest. Trying for more even lighting will help. ........... Karl has joined the diamond trade and is now posting as Karl_K

Face down photos are great adds for terrific optical symmetry and H&A, but when those are not the issue... what do these tell me (aside clarity) ?

Wait a minute... even secondary reflections seem to match to a tee.

Soon Rough Rock Total Posts: 4 Last Post: 2/2/2005 Member Since: 1/31/2005	Thanks to all your input. So, should I use backlight or not? What are you guys looking for in a daylight picture? Please be specific. Thanks. Soon

Soon Rough Rock Total Posts: 4 Last Post: 2/2/2005 Member Since: 1/31/2005	It's a real one. My lens is kinda sharp - it will show any dust, inclusion or flaws on the stone. What do buyers, appraisers or manufacturers or labs looking for in a daylight photo? Do they want to see a realistic or a 'pretty-looking' one which i can use software to touch up. Soon
