More proprietary software treating their users like criminals as the default.

What legitimate use case can you think of where the benefit of faithfully reproducing currency is not outweighed by the need to prevent the proliferation of counterfeit currency?

There's a joke about a famous prophet in there somewhere.

And I jest, but there's a point in my quip too:

Annoyingly getting in the way of creative workflows probably does very little to prevent actual counterfeiting in comparison to what it does to enhance the piety surrounding our increasingly digital origami deity.

At least in the US, ‘old’ bills are still legal tender. A counterfeit bill pre-holograms and recent security stuff is still usable in public.

This. There are relatively few visual cues for laypeople to detect counterfeit older (and even moderately recent) US dollar bills. There are no UV sensitive areas, the watermark line is rather faint and there's no special stuff like holographic images, transparent inserts or metal foils etc. The only way I've really seen people check medium denomination ($10s, $20s, $50s) bills is via an iodine pen test which would r…

Some people (James Randi in particular) spray starch on real bills to increase the false negative rate. http://archive.randi.org/site/jr/070105quality.html#7

That link also contains an account of the problems someone faced when using that technique.

Or just sell the t-shirts and get rich… NFT’s are worthless hype

A t shirt is just a real life nft. It's just as worthless.

If worse comes to worse, you can use a T-shirt to wipe your arse, at least. More benefit than any NFT

Years ago I had an Austrian 5000 Schilling note in absolute mint condition. It was a beautiful note with an image of Mozart on it but it was too expensive for me to keep just to admire (~$500 USD) so I cashed it in for local currency. (Also, it had to be converted as the Schilling was being made obsolete by the Euro.) However before I did I wanted to keep a permanent record of it so I scanned it in the highest resolu…

In hindsight do you think it would have been profitable to hold onto it? A quick look at eBay the listings range from ~500 EUR to ~2000 EUR. But what they actually sell for is what matters.

Makes me consider getting some nice Croatian Kuna bills before the end of the year and hold on to them for 20 years.

The first x64 patch I ever did was to remove this very protection from Photoshop years ago. It was a single instruction patch, 1-3 bytes changed, I don't remember exactly.

Curious, as I'm totally oblivious to this - how does one patch a closed source binary to get around this protection?

Given the detection code is in a separated library, it should be relatively easy (supposing the code is not obfuscated) to find out where it is loaded/called.

> But color ink, on paper of the right color and feel? Someone pulling off right color and feel is not going to be stopped by CBCDG's crusade to put some nonsense into Adobe Photoshop.

Yes, the feel of the paper in particular is impossible to casually replicate. However, what makes you think a particular minimum wage employee can actually feel the paper? People get injuries that affect their senses in weird ways. It’s still not fair to say that they “deserve it.” That said, I agree that Photoshop should not have this code. It’s on the Photoshop user to not be an asshole. That shouldn’t be Adobe’s p…

>a particular minimum wage employee

Well then perhaps that should be the cost of employing people with minimum training for minimum wages. No sympathy.

A few years ago I extracted the CDS logic and got it working in Linux so I could experiment with it: https://twitter.com/taviso/status/902997594460135424 I had planned to see if I could come up with an image that would still be detected even with significant distortion, and then print it on a t-shirt... The idea being you couldn't open a photograph of me in PhotoShop! :) I got sidetracked, but I should get back to th…

It was DVD, but yes. :)

I still think I have my Perl DeCSS t-shirt somewhere in my mother’s basement :D

I still remember a lot of 09 F9 11 02 after all this time.

What about other software? Or online apps like Photopea?

I have old copies of Corel PhotoPaint that predate the introduction of the Euro; they can open and manipulate Euro images.

Also, Stable Diffusion is currently able to generate semi-realistic images of dollar banknotes.
