The TCP/IP protocol suite is being used for communications,whether for voice,video,or data.There is a new service being brought out for voice over IP at a consumer cost of 5.5 cents per minute.Radio broadcasts are all over the Web.Video is coming,but the images are still shaky and must be buffered heavily before displaying on the monitor.However, give it time.All great things are refined by time,and applications over TCP/IP are no exception. Today,you will not find too many data communications installments that have not implemented or have not thought about the TCP/IP protocol.TCP/IP is becoming so common that it is not so much a matter of selecting the TCP/IP protocol stack as it is selecting applications that support it.Many users do not even know they are using the TCP/IP protocol.All they know is that they have a connection to the Web,which many people confuse with the Internet.We’ll get into the details of the differences later, but for now,you just need to understand that the Web is an application of the Internet. The Web uses the communications facilities of the Internet to provide for data flow between clients and servers.The Internet is not the Web and the Web is not the Internet. In the 1970s,everyone had some type of WANG machine in their office.In the 1980s and early 1990s,Novell’s NetWare applications consumed every office.Today,NetWare continues to dominate the network arena with its installed based of client/server network applications.However,the TCP/IP protocol and Internet browsers,such as NetScape’s Navigator and Microsoft’s Internet Explorer,and Web programming languages are combining to produce powerful corporate networks known as intranets, which mimic the facilities of the Internet but on a corporate scale.Intranets from different companies or simply different sites can communicate with each other through the Internet.Consumers can access corporate intranets through an extranet,which is simply part of the corporate intranet that is available to the public.A great example of this is electronic commerce,which is what you use when you purchase something via the Internet.Directory services are provided through Domain Name Services (DNSs) Microsystems.File and print services are provided in many different ways.Finally,the ultimate in full connectivity is the Internet,which allows the corporate intranets to interconnect (within the same corporation or different corporations),providing global connectivity unmatched by any network application today.Therefore,within a short time (possibly 1998),very powerful applications will be built that utilize the TCP/IP software suite that will eventually rival NetWare at the core.

If you are reading this foreword,it probably means that you’ve purchased a copy of Adobe Photoshop 6.0,and for that I and the rest of the Photoshop team at Adobe thank you. If you own a previous edition of the Photoshop Bible,you probably know what to expect.If not,then get ready for an interesting trip. A lot of attention in various forums has been given to the fact that the year 2000 marks the ten-year anniversary of Adobe Photoshop.Unless you buy this book almost immediately after it comes out,I will also have been working on Photoshop for ten years,so this seems like a good time to do a little looking back. When I joined the Photoshop team,my first task was to start adding vector drawing capabilities to a program that even in 1.0 could lay claim to being the leading desk-top raster editing program.In other words,I was to implement a Bézier pen tool that as initially planned was little more than a glorified lasso tool.Ten years later, Photoshop 6 is now taking vectors on in earnest.I trust that doesn’t mean that we sat still for the 9+years between Photoshop 2.0 and Photoshop 6.0.It certainly doesn’t feel that way. If we had done so,I suspect that we would have heard from Deke McClelland since he’s been watching over our shoulders for almost as long as I can remember. While Photoshop 6 probably provides more instant gratification features than any previous version,at its core it offers a broad collection of basic and not so basic tools for building and manipulating images.Becoming a skilled Photoshop user involves getting to know those tools,how they interact,and when to use them.The best way I’ve found to do that is through use,exploration,and play.On the other hand,since Photoshop allows one to do so much,it can be difficult to know where to begin.It’s like opening a watch maker’s tool chest:The screwdrivers are pretty obvious,but what about all these other strange and mysterious instruments? This is where Deke comes in.In Deke’s hands,Photoshop goes from being just a toolbox to being a strange and wonderful land all its own.The Photoshop Bible is a guided tour through that land with a guide who has been over the territory many times. Deke takes you through most of Photoshop and covers a lot of areas in impressive depth.Not only does he show you the features in Photoshop —after all,you’ve got xvi Foreword the manual to do that —he shows you how to use them to address issues that look almost like real world problems.This is the Photoshop Bible not the Photoshop Encyclopedia and hence it tells stories rather than just presenting information. A second thing that you’ll get from this book is a lot of commentary.Deke isn’t shy about letting you know how he feels about various features.I don’t always agree with Deke’s opinions on these matters,but I think his openness about his opinions makes the book much richer.If you become a routine user of Photoshop,you will almost certainly develop your own opinions,some of which will probably match Deke’s and some of which probably won’t.It’s valuable to get his opinions during the tour,however,because,even if you end up disagreeing with them,they give you more to think about. Finally,the most invigorating aspect of this book is the enthusiasm Deke brings to the tour.You’ll note that I included “play”in my list of strategies for coming to know Photoshop,and I think just having fun with the program is really one of the best things you can do when starting out.Deke almost relentlessly conveys that sense of excitement and fun,and for that I thank him. So,fasten your seat belts,put on your pith helmets,and get ready.It’s a fascinating trip ahead.
