No.
Acetone does not need to be "rinsed." It's so volatile that it evaporates without a trace left, so as long as the last thing which touches the...
Your experience is correct. :) The macro setup I'm describing isn't capable of a full-slab image. For those, I switch to (in my case) the stock...
This. One single isolated spot of PVC isn't out of the ordinary. Won't hurt anything to soak the whole coin, indeed it's probably the better idea....
Either way, it's a pretty tight-fitting holder. One's just....a little tighter than the other. :)
Three cardinal rules of computing were likely broken here: 1) Back up. Back up. Back up. 2) Don't play around in an Administrator-enabled account,...
Like me, quite often, the Shift key got in the way of effective typing. :) Images this good with very small-sensor cameras like your Nikon...
The bad news is, your camera offers very little manual adjustment. The good news is, it sure doesn't look like it really needs it. :) You do have...
I'm throwing so little light at the matter that ISO100 is usually the best I can do unless I do a bathroom trip while the exposure is happening,...
That's more light than I use in my photography; my Jansjos are 2w each for a combined total of 140 lumens. Adjustability is key for making that...
If that be true (now that I think about it), at least I can take solace in the fact that the OP missed it too. :)
The White Balance is off on the original images; green18 corrected that in postprocessing by eliminating all color. In the real world, I suspect...
This is a key date for the series, and a rather pricey piece. Yours looks to be - at least from the one image, it would be strongly preferable to...
If the corrosive agent is strong enough to remove metal - acid and the like - it will remove the metal with near-perfect evenness, and the coin...
Where was one of those posted? These are plainly from the original poster's camera - they even still have embedded EXIF data and were shot this...
Then we get to say, "Not only have we seen this before, we've seen this exact coin before." :)
I expect the IHC presented here is spooned, for the era of the coin and lack of face damage - which you correctly infer may be expected of a dryer...
Shellac. :)
I'd be inclined to think not; there always seems enough sulfur dioxide around to eventually turn it green. You'd have to arrest atmospheric exposure.
I would agree with this evaluation - the coin has been viciously damaged rather than anything happening at the Mint. Note the impressions from...
Separate names with a comma.
