Chris
The general consensus seems to be that Photoshop CS is slower on many
operations but faster on others. One way you can speed up opening files, if
you are opening them from the file browser, is to Cmd+Opt [Ctrl+Alt] on the
thumbnail. That will close the File Browser and prevent it from competing
for precious resources while Photoshop is trying to display your file and
menus.
It's also quite possible that the "counterfeit deterrence system" embedded
in Photoshop CS is taking a long time to scan a 300mb file. On the Adobe
forum, Kevin Connor, a prominent member of the Photoshop team, said
Photoshop CS only takes a fraction of a second to scan an image but he did
not specify a file size (see his post below my sig).
Frankly, I can't see the benefits of CDS. If I was a counterfeiter, I would
just make sure I do not upgrade to Photoshop CS, and, IAC, counterfeiters
are hardly likely to purchase a legal copy so it's no skin off their nose!
Why not spend that extra engineering time on something useful to the general
user?

Maybe increasing support for 16/bit files has something to do with
it?...Just guessing. If it has, I would rather have the speed and a few
color correction tools in 16/bits channel mode and do the rest of the
editing in 8/bits per channel mode (as per Photoshop 7.0).

As someone at Adobe who was involved in the decision to include counterfeit
deterrence in Photoshop CS, let me finally provide you with a response to
all of these concerns and questions. Sorry for the delay!:
Photoshop CS does indeed include a counterfeit deterrence system (CDS) to
prevent the illegal duplication of banknotes. The CDS was created by a
consortium of central banks from around the world. We, along with other
hardware and software manufacturers, have included CDS in our products at
their request to address the threat posed by the use of digital technologies
in the counterfeiting of banknotes. There are other software products from
other companies that already use this same technology. There are also
hardware products that use the same or similar technology. For example, most
color copiers sold today will not allow you to copy currency.
As digital imaging technology advances, becoming more broadly available
and user friendly, the old barriers to currency reproduction are becoming
less effective. The unscrupulous are taking advantage of the functionality
that is being provided to the vast majority of honest users for the purposes
of counterfeiting currency. In the US and around the world, counterfeiting
through digital means is increasing exponentially, and retailers and the
general public--including our own customers--are at risk.
Counterfeit currency is essentially a hot potato. Whoever holds it last,
loses. The person who loses isn't necessarily the counterfeiter. There's no
government body in place to "reimburse" people who, through no fault of
their own, get paid with currency that turns out to be counterfeit. In our
implementation of CDS, we've worked very hard to balance the need to
protect these unsuspecting victims of counterfeiting along with the need to
continue to provide a product that efficiently does what honest customers
need it to do.
There appear to be several major concerns and objections repeated
throughout this message thread, so I'll try to address each one
individually:
1. Performance: CDS does not cause any noticeable slowdown in Photoshop
performance. During most operations performed in Photoshop, CDS is not
used at all. When it is used, the performance impact often is just a
fraction of a second.
2. Legal use of notes: It is true that the current implementation of CDS
will prevent you from scanning in your own banknotes even if your usage
intent is entirely within legal boundaries. Regulations for using banknote
images vary by country. It is the responsibility of the central bank in each
country to provide images that can be used within the legal guidelines of
that country. In other words, if you want to legally reproduce images of the
new $20US bills on a Web site or in a marketing brochure, you can contact
the U.S. Bureau of Engraving and Printing for legal images that can be
opened and manipulated in Photoshop CS. (You can visit them at
www.moneyfactory.com.) Similar solutions should be available in other
countries. If you find that your central bank is not providing adequate
support to permit legal uses of their banknote images, then you should let
them know.
3. Adobe's intentions: Please be assured that this implementation of CDS is
not a step down the road towards Adobe becoming "Big Brother." We know
that one of the reasons people love Photoshop is because it's an incredibly
flexible tool that can be used for so many different things. That's also one
of the reasons we at Adobe enjoy working on new versions. Finding ways to
prevent you from doing things in Photoshop really doesn't interest us!
Moreover, the CDS is not Adobe technology, but was provided by the central
banks, who would have no reason to want to restrict anything other than bank
notes. Counterfeiting is really a special case in which we could see how our
own technology advances were making it easier to commit crimes and we
were asked to implement a solution that would have minimal impact on
honest customers. Yes, there is some impact, in that you need to contact
your central bank for images, but our hope is that it's not a huge
inconvenience for that small group of customers who do need to reproduce
these images in their graphic design work. It also provides the central
banks with an opportunity to better educate customers on exactly what is and
isn't legal usage.
Of course, CDS in Photoshop CS is essentially a 1.0 implementation of a
feature, analogous to the state of the layers palette in Photoshop 3.0. We
realize that there may be room for improvement, particularly if there are
corner usage cases that weren't taken into account in our current designs.
We do want to hear about your concerns, and we definitely want to hear if
there's a specific problem that this implementation has created for you. As
with any Photoshop feature, we depend on hearing from customers so that we
can make continual improvements release after release.
