Question regarding photos with Ideal Scope

[Adylon]

This question is a follow up to this thread which I found very helpful:
https://www.pricescope.com/community/threads/standardizing-lighting-for-ideal-scope-reflector-type-photography.27251/

I'm considering using the setup in this photo attached. Basically it's similar to John's setup, except it's inverted and photographed from the bottom, this way the diamond sits on glass and therefor the face of the stone should always be parallel to the plane of the camera lens and not need to be adjusted and always be dead on straight (hopefully). Also I was thinking to add a white reflector around the diamond from the diffuser to block out any ambient light in the room.

My only concern is John's setup shows their stones are slightly recessed into the idealscope (girdle-deep) and mine would not be quite flush. Would this make a difference in the images and if so how? And how do you accurately determine if the edge of the idealscope is perfectly lined up to the girdle of the stone? I imagine this is not an exact thing so there is wiggle room? I was therefor hoping it was not needed to be inside the idealscope at all or slightly outside?

Are just the pink reflectors (no optics) available to purchase? If not, is it just a translucent pink tube? Same question with the ASET, is there a reflector that can be purchased with no optics?

Thanks in advance

Here''s the photo I hope it attaches.

Anyone?

Garry is just getting home from a 5 week vacation.
I''m sure he will check in when he gets caught up a bit.

Hi, I took this picture with the exact same setup as you descibed with only my white ceiling and ceiling light behind it. I had to take a few pictures and move my ring around to finally get it somewhat centered. Hope this helps.

ETA: The actual pictures are much more clear and crisp than how they look uploaded on PS.

Dear Yosef,

You assumption that sitting the table on the glass is best is just that.

Actually a hole for the pavilion to sit in makes alignement easier because the pavilion alignemnt is more important than table alignment. we made a small number of those plastic rotating stands, but unfortunately I only have enough left for my own use.

Have you read this www.ideal-scope.com/newletters_issue008.asp

Thanks to those that replied. Thank you Garry.

If the alignment of the pavilion doesn''t automatically occur when the table is aligned I guess there''s no point in doing everything upside down. I''m just trying to figure out the best setup before I buy equipment.

My goal is to use 1 aparatus for taking IS images, ASET images, natural light images, display images on a computer screen live in a store, and take high resolution pictures using my 12MP canon SLR camera all in one. I was thinking to use an inverted trinocular microscope with an adapter for my camera that has a live view mode and shoot things upside down. But maybe I''ll have to come up with another way and just use a regular trinocular microscope instead.

Also Garry, is there a way to purchase the ASET and IS reflectors without optics? I ask because I''d rather not have any optics between my camera''s image sensor, and the diamond, other then the microscopes internal optics. I''m hoping to get the sharpest picture possible. I won''t even be using a lens on my SLR camera, I''ll be using this adapter I''ve attached.... It''s designed to fit straight on a microscope.

Thanks again for your help

Garry is refering to the possibility that the table is not aligned with the girdle-plane. This occurs and he and I probably disagree about the frequency of this occurring.

This also poses problems in the Sarin-measurement, and as such, it is a big plus for Helium-measurement, where this is spotted.

On the other hand, AGS use a similar upside-down set-up for their ASET-photography. And HRD last week announced a H&A-system, in which the same table-down-approach is used. Whether this is a big error depends upon the frequency in which the table-plane is not the same as the girdle-plane.

Live long,

I''m sorry, please disregard my post. I thought you wanted to check a diamond for possible purchase, not for business purposes. Good luck!

No problem I appreciate the reply. You did a pretty good job taking your photo with the stone set in the ring and everything Your profile photo is very nice as well.

Best,
Yosef

Thanks Paul. May I ask, in your opinion, how many GIA-VG cut grade stones would be table/girdle/pavillion parallel sufficient for a clear ASET/IS photo? 80%? 90%? 95%? 99%? If it's closer to 95% or higher maybe I shouldn't worry about it so much

I guess I could always make some sort of X-Y table that can be slightly adjusted for pitch to correct any error, and use it to hold one of the peices of glass above the microscope opening. This is becoming a bigger project then I thought

Thanks again,
Yosef

I just noticed, your ring maker set your stone with the prongs perfectly lining up on 4 of the arrows... I''m impressed. Nice attention to detail.

Why not just get this and be done with it?

I''ve been considering purchasing that, but it doesn''t appear to take IS photos, natural light photos, etc. I also figured it would be nice to have some setup capable of easily photographing VVS size inclusions if possible using high resolution... I could use the microscope to move around the stone and snap a high res shot, not just 1.3MP. I''d prefer to have an all in one type thing if possible, so I don''t have a bunch of devices or inventions on my desk. And last but not least, I just like building things myself But I still might get that AGS device, looks pretty slick

For regular pictures and vids get a canon SX100 IS or s5is or a g9 then use the remote capture software for stills.
If you need more functions this software rocks when used with it:
