Adobe Photoshop CS

Adobe Photoshop has long been the choice of professional photographers and serious amateurs. Photoshop CS sets a new standard for photo editing by expanding on Photoshop's existing strengths and by adding some features that will make you wonder how you got along without them.

Adobe has a new family of products under the "CS" (Creative Suite) medallion. I'm trying to get my hands on an evaluation copy of InDesign and the other parts of the suite, but Photoshop CS is included in the current version of Adobe's Video Collection suite. You'll hear about video in a later program, but Photoshop deserves to be in the spotlight all by itself.

It's difficult to do justice to an application like Photoshop on the radio, so I'll provide some samples of work I've done here on the website.

You may already know that the Clear Channel stations in Columbus are all moving to a single building on Fifth Avenue west of the Scioto River. Stations that were at The Continent moved on February 1. WTVN and the stations that are on Dublin Road will move sometime this Spring. Late last year, after the building had been stripped down to bare concrete and before construction had begun, the company held a "party" in the space and I was there to take pictures.

Click any of the images below to see a larger (although not full size) copy. Some of the "large" files are more than half a megabyte, but the original files were larger than 2 megabytes.

I used an on-camera flash, but light coming in the windows overpowered the flash and the camera's automatic exposure couldn't find a way to get a well exposed image. It did the best it could and the result was an underexposed image. With digital images, underexposure is always preferable to overexposure because there is detail in the shadows even if it appears not to be there. This image could be saved with a little judicious use of tone curve manipulation, but with Photoshop CS it can be saved a lot more easily.

I used the Shadow/Highlight adjustment dialog to produce two improved images. This is the default adjustment. I did nothing more than choose the dialog and click OK. This is clearly a huge improvement over the original image.

But I thought I could do better with some manual adjustments. The default for this image made no change in the overexposed highlight areas of the windows. I also felt that the change in the shadow area was slightly too great and that the tonal width in both shadows and highlights could be increased slightly. (By the way, I'm not working on a Mac, although you might think so based on the screen shot. This is Windows XP with WindowBlinds and a Mac OS X "skin".)

This is the result of making the manual changes. Is it better than what Photoshop would have produced without my "help"? You decide. The colors are less accurate in this image, but I think I've controlled the blown-out highlights a little better.

Or maybe not.

Photoshop CS has improved the "color replacer" function. It's still not "perfect" (meaning that it can do only what you tell it to do instead of what you want it to do) but it works better than any similar function I've ever seen.

Here is the architect of the new Clear Channel studios explaining the color concepts used in designing the new studios. The colors are deep, saturated colors. Purple is one of the colors used. Prior to construction of the studios, the walls were bare.

I thought it might be interesting to replace the bare walls with purple. When an application replaces colors, all it has to go on is hue, saturation, and brightness. I selected the wall and fiddled a bit with the "fuzziness" selector. Then I added and deleted some colors. The result is surprisingly good because this is not an image that I would consider to be a candidate for successful color replacement. The replacement colors on the wall are good and the bleed-through (check the architect's now slightly purple beard) was surprisingly limited.

Impressed? Yeah, just a little!

What you've seen so far is literally just the tip of a very large iceberg called Photoshop CS. The image browser (at left) is wonderful, allowing the user to mark images for rotation when they're opened, to open multiple images simultaneously, to view the EXIF "metadata", to modify or rename images in a batch, to create a contact sheet, to rank and sort images, and even to add notes. Previously, photographers had to shell out big bucks for an image management program to do these kinds of things.

If you own one of the pro or semi-pro digital cameras noted below, a plug-is is available to allow Photoshop CS to manipulate "raw" images from the camera. This means you can start with an image in the camera's highest possible quality setting and edit it in Photoshop.

Photoshop can show and edit raw files from Canon (EOS-1D, EOS-1Ds, EOS-10D, EOS-D30, EOS-D60, EOS 300D Digital Rebel/Kiss Digital, PowerShot 600, PowerShot A5, PowerShot A50, PowerShot S30, PowerShot S40, PowerShot S45, PowerShot S50, PowerShot G1, PowerShot G2, PowerShot G3, PowerShot G5, PowerShot Pro70, PowerShot Pro90 IS); Fujifilm (FinePix S2 Pro); Leaf (Valeo 6, Valeo 11); Konica Minolta (DiMAGE A1, DiMAGE 5, DiMAGE 7, DiMAGE 7i, DiMAGE 7Hi); Nikon (D1, D1H, D1X, D100, Coolpix 5700, Coolpix 5000 - with firmware version 1.7); and Olympus (E-10, E-20, C-5050 Zoom).

The native-mode editor in Photoshop doesn't offer all the features that you'll find in the camera manufacturer's application for raw files, but it offers enough to allow the average user who wants to shoot in the camera's native mode to do so. Professionals will probably shell out the additional $200 or so for the application that gives them full control over the native files. The image at the left is Nikon's Nikon Capture application. The image at the right is Photoshop's native file view. Click either image for a larger view.

Not new to this version, but incredibly easy to use: Perspective correction. If you've ever taken a picture of a building and have then been disappointed because the building appears to be falling over backwards, you've encountered perspective "distortion". I used "scare" quotes because the problem isn't technically distortion. The camera lens simply did what it was supposed to do. The resulting image looks wrong, though.

Here is an image of Shot Tower at Fort Hayes. You'll notice that the image leans to the left a bit and that, because the camera was tilted up slightly, the building seems to be leaning backwards. Both of these problems can be corrected in a single action.

Photoshop makes fixing this problem nearly automatic.

All I need to do is use the crop tool and make sure that "perspective is checked. If you don't select the perspective option, this won't work the way you want it to.

The next step is sometimes a little difficult to understand but will make perfect sense once you think about it. You need to create a quadrilateral* (4-sided figure that does not necessarily have any right angles or parallel sides) cropping area that defines the top, bottom, left, and right sides of any part of the image that should be rectangular. In the image at the left, I used the tops, bottoms, and sides of the windows on the 2nd and 3rd floors.

Once you have defined this area, you can then drag the center areas of the 4 lines out to define the area you want to retain in the final image, without touching the corners. I cropped away some of the blank sky and the areas at the side of the building. The area defined by the quadrilateral (shown as the lighter area of the image at the left) is what Photoshop will convert to a rectangle.

Now all that's left to do is to press Enter.

And I have a straight image of Shot Tower that's not leaning over backwards. It just doesn't get any easier than this.

* Initially, I wrote "rectangle" here, but realized that the figure I was showing wasn't a rectangle, but a 4-sided figure that would be converted to a rectangle. It's been so long since I've used geometry that I couldn't think of the general name of 4-sided figures. A Google search for +"4 sides" "not equilateral" +"not parallel" turned up a "Basics of Geometry" outline that defined points, lines, and geometric shapes.

Just too much?

If Photoshop CS is too much (money, $650) or too much (to learn) then consider Adobe Photoshop Elements, Photoshop's little brother. Photoshop Elements replaces the complex adjustments panels with easier to understand (for amateurs) controls. While users lose some flexibility and control, they gain quick operation and ease of use. Oh, and it costs a lot less, too.

If you need all the functionality, Photoshop CS is your application, though. Accept no substitutes.

Technology corner rating for ADOBE PHOTOSHOP CS
EIGHT CATS: If you're a first-time buyer, you'll gasp at the $650 price tag for Photoshop CS. Those who are upgrading from a previous version will pay $170. Adobe has largely priced Photoshop out of the amateur market, except for amateurs who have a big budget. For serious amateurs and professionals, there is no other image editing software that can take Photoshop's place. The only problems I have with Adobe Photoshop CS is the cluttered workspace (I really wish I had a second monitor where I could put the palettes) and the price. It's a solid performer that continues to set the standard for image editing.

Scope this calendar

Not everybody owns (or needs) Outlook to keep track of appointments and tasks. For $30 you can have an organizer program that can be synchronized with your Palm device, that can handle repeating events as easily as one-off tasks and appointments, and that communicates with a neat (and free) on-screen clock.

First, the clock. You've probably seen DS Clock in other screen captures that you see on this site. If I capture the full screen, DS Clock is there at the top of the screen. I've configured it to show the time in GMT and Eastern along with the full date, the week or the year and the day of the year. If I hover the mouse over DS Clock, it displays any current Calendarscope reminders. Whether you use Calendarscope or not, DS Clock is a most useful utility.

If the application has a shortcoming, it's that there is no address book function. It's "just" a calendar and to-do list. Nothing else. But it handles those two functions very well. The program allows the user to create single or recurring events, to color-code various types of events, and to set reminders for upcoming events.

CLICK ANY OF THE IMAGES BELOW TO SEE A LARGER VIEW.

Here is Calendarscope's full month view. The icons at the top allow the user to select from various views -- 1-day, 5-day, 7-day, full month, or task list.
Here's the daily calendar for February 8.
This is the "week-at-a-glance" view.
And finally a view of the to-do list.

Calendarscope also provides various views of your schedule -- daily, weekly, monthly, or yearly. The Task and TaskPad views show all scheduled tasks, including those that are active, overdue, or completed.

Calendarscope allows you to synchronize your data with Palm OS handhelds or print your calendar. You can also choose "Save to HTML" if you want to publish your calendar on a website or put it on a corporate intranet.

As with many applications that have been written by Russian programmers, Calendarscope is both flexible in terms of operating system requirements and conservative in using system resources. Windows 95/98/ME/NT4/2000/XP/2003, Pentium 90 MHz or higher processor, 32 MB of RAM, and 3 MB of available hard disk space.

Technology corner rating for CALENDARSCOPE
? FIVE CATS: If you're someone who needs an integrated calendar, address book, notepad, and task list, this product is not for you. While it's uncommonly easy to use and integrates beautifully with the free DS Clock applet, Calendarscope doesn't have the extra "office" features.

?

EIGHT CATS: If you need just an easy-to-use calendar, to-do list, and reminder program that's most affordable, takes few system resources, and integrates beautifully with the free DS Clock applet, Calendarscope is exactly what you're looking for.

Exciting news: I found a bug in UltraEdit

UltraEdit has been my favorite text editor since about 1997. It seems longer, but I see on the UltraEdit website that the application wasn't invented until 1996 and I'm sure I wasn't one of the first few people to use it. But UltraEdit has served me well over the years because of its ability to edit any kind of file I throw at it -- text, binary, you name it. Version 10 was released earlier this year and I've been using 10.10 for the past few weeks.

In early November, I noticed that when I saved a file that had word wrap turned on, if my cursor was anywhere on a line that wrapped, the final space in the line above the line the cursor was on would be deleted. Eventually I figured out exactly what was happening and wrote to the author with a complete explanation. His reply: We fixed that in version 10.10a. I thought I'd found my first UltraEdit bug. And I suppose it was, but it had already been fixed.

Less that a week later, I wrote a little macro -- similar to ones I had written many times before in earlier versions. There wasn't much to it. All it was supposed to do was examine a log file, find a domain name, copy the line with the domain name, hop over to a "result" document, and paste the line of text there. It worked perfectly -- I could see the macro skipping down through the file, stopping briefly at each appropriate line. I could see it hope to the other document and return. Perfect. Except for one thing: The line of text never got copied to the results file.

I thought I had lost what's left of my mind. I rewrote the macro with minor changes. I closed UltraEdit and restarted it. I rebooted the computer. Nothing worked. The easiest macro in the world wasn't working. So I sent a note to the support folks. We chatted back and forth (or is that forth and back?) for a couple of hours and finally I received another macro. "Try this," the note said, "and see if it works." It did. I thought I had done something incredibly stupid.

As it turned out, I had uncovered an obscure bug that had crept into the code. An hour or so later, another e-mail arrived with an attachment. Version 10.10b (Beta). "Try this and see if it solves the problem," the message said. I wrote another macro and the result was exactly what I expected.

What a memorable day!

It's patch time again

Like an old pair of jeans, Windows (and most other operating systems) need security patches from time to time. Microsoft announced a major security patch late Tuesday, but the patch wasn't available on Microsoft's website until Wednesday. The patch is designed to correct long-known (SIX MONTHS) flaws that, according to Microsoft, could allow "an unauthenticated, remote attacker [to] execute arbitrary code with the privileges of the process using the ASN.1 library. In the case of most server and authentication applications, an attacker could gain SYSTEM privileges."

On an automotive level, this is like giving the town car thief the keys to your car.

For complete details and the patch, follow these links:

If you don't care about the details and just watch the patch to fix the problem, you'll find it at http://windowsupdate.microsoft.com. You must use Microsoft's Internet Explorer 5 or higher to use the Windows Update service.

Litigation as a profit center

It seems that all someone has to do is come up with a good idea (say, for example, Google) and some company you've never heard of before (American Blind, for example) hires a phalanx of hired goons to shake down the company. It's all perfectly legal, of course, because it's done in court.

American Blind is annoyed because they say Google infringing on its trademarks by returning non-sponsored Web search listings from competitors when certain terms are queried. Now it seems to me that if I open the Yellow Pages to search for window coverings that I'll probably find several providers on the same page. This may be shocking news to American Blind and the company's lawyers, but that's the way directories work. When a consumer is looking for a product or a service, the consumer probably would like a choice of providers.

That's how Google's "AdWords" work. Google's listings come from an index of something like 3,000,000 website pages. They are ranked by a formula that Google considers "proprietary". In addition, Google sells keyword-based listings in its AdWords program. Those listings appear at the top of the page and on the right edge of the page (and are clearly denoted as advertisements).

The lawsuit, filed in the US District Court for the Southern District of New York, fails to take into account different kinds of searches and results that Google provides. American Blind has also named America Online, Netscape Communications, CompuServe, Ask Jeeves, and EarthLink in the suit.

The new American business model seems to be: If you can't make a profit selling your product, sue somebody with deep pockets.
