Here's my guess:

1: Low Grade Telecom
8: Peripheral as is. You should remove the shield. It might get Low Grade Telecom or higher.
9: Midgrade

Rest Perpheral

All correct except 8
8 if the shields are gold flashed don’t remove them.
If that’s your flash find a new phone or camera, meany. Lol

9, this is a tuff one. As Chris said there’s both art and science in grading at the commercial level. The ISO markings tell me this is a flat board, which is wrong just from my own experience so this is a Chinese knockoff board.
As such we are faced with pure experience.
The IC population isn’t there for peripheral. Nor is the copper content. With switches and relays plus the base components I’m guessing around 5-8 ounces of copper here.
The flashing isn’t gold. Based on experience and looking at the photo on an HDR 12-bit display.
I can see the lines in the sheen. Any good scam can turn copper into ‘gold’ by adding tin and zinc. The more tin the golder copper looks. Zinc stabilises rf leakage.
For reasons other than what CC was looking at I’m calling midgrade. And only just barely. Chris’s people don’t dive as deep into boards as I do. I’d be about a third the rate myself.

I was picking on the general situation of
‘Let’s snap a phot of anything remotely reflective with an 8-bit 5Mp camera under direct incandescent bulbs and see if anyone can figure out what the colours are’ issue.

You said enough to convince me. Leave them on
CC, midgrade


It’s not your camera. It’s the combination of 8-bit Linux (including Android is Linux no matter what google claims) and unadjusted iPhone lenses with old standard lighting or modern replication bulbs.

Btw if you plan to take photos for any reason do NOT buy daylight, white, or “pure white” bulbs. All of them are blue spectrum sub white.
Use Soft White (a registered TM) LEDs and CF or tubes for photos

Further note: for newer users I’ve mentioned a few times before I have problems in the blue range of the colour spectrum. I’m missing the blue class transitional cones.
If something is down to colour... I am wrong apx 1/3 of the time for that reason. Well notot really 1/3 and more like 72.667~%. But whatever.

For the more intellectual:
I am legally in the class the sub class of Tritanopia knows as Tritanomaly. Which is actually inaccurate as I have minimal low red issue. Tri-Ms see yellow messed up and I can constantly pick yellow shades from ‘blind’ tests.
