First Look Photoshop 7.0, Is It Worth The Upgrade
By David B. Brooks July, 2002

A browser is a real convenience when you are hunting for
an image file you want to open. Also,having access now to
the metadata (EXIF file header) digital camera data is a
great advantage. However, browsers for photo applications
have been around for years, so why did it take so long or
Adobe to provide this convenience to Photoshop users?

When I read the general description
of what was new in Photoshop 7.0, my expectations were high that what
I would experience would justify a full upgrade number from 6.0 to 7.0.
After whining to the Photoshop team about poor retouching tools for the
last couple of years, I was anxious to see if they had listened.
There are four features in
this upgrade that are new and which relate to the digital darkroom and
photography. As usual, most of what is new is for illustrators and web
page building. This always puzzles me since 85 percent of the illustrations
that are published are photographs, compared to relatively few that are
created from scratch by an illustrator. Usually what is new for photographers
are tools that are needed to help work with digital photographs. But I
was very disappointed once I tried using the four new features that are
photographically useful, or rather should be.
New Browser
The first change is a new browser that opens a window of thumbnails of
images in any folder you can access from Photoshop. The browser reveals
all of the text data in the file header, including identification of the
embedded profile. For digital camera files, the metadata in the file header
includes the date and time the image was made as well as the settings
used to make the exposure. All of this is great. But other than the metadata
header information, other image-editing applications like Micrograx Picture
Publisher have had an opening browser for at least a half dozen years,
so what took Adobe so long to include such a convenience in Photoshop?

Automatic image adjustment features are like autoexposure
on a camera. They only work effectively with typical, average
subjects. If the subject is unusual and should be adjusted
specifically for one attribute, like skin tones in a face
close-up, and the background is a strong color, Auto Color
will shift the skin tones to something way out of the ballpark.

Auto Color
Another much ballyhooed new tool is Auto Color. Now I have grave doubts
about auto-adjust anything photographic because it is based on the false
premise that all subjects/photographs are the same. In other words, the
software cannot tell whether the subject is a black cat in a coal mine
or a white horse in a blizzard, so how can it make an automatic and appropriate
adjustment when it doesn't know what it is adjusting? In my experience
all images are unique and an ideal adjustment must be done with intelligent
consideration of what is appropriate for that subject and the way it is
illuminated.
To back-up this opinion I made
some simple tests. In the past, doing tests of new and different films
I always made some bracketed exposures of the ubiquitous MacBeth Color
Checker, so I dug out a few of these made on different films and made
raw scans of them just adjusting the gamut in the pre-scan. I made two
copies of each Color Checker image, and then proceeded to manually adjust
the colors using the Levels dialog's eyedropper tool to set the highlight
and shadow as well as the mid-tone grays to remove any color cast. Then,
on the second copy, I used Auto Color to do the same thing.
Well, the Color Checker has
a pretty typical, even distribution of colors, and it did a good job adjusting
the colors by removing any color cast in highlights or shadows. But it
must assume all images scanned have parallel density curves for each of
the RGB channels, because it did not remove color casts caused by the
RGB curves not remaining parallel in the mid tones.

There remains essentially only one useable retouching tool
in Photoshop, the Clone Stamp. The Healing Brush is a modified
rubber stamp that is intended to make using it easier, but
at the cost of being very slow and often inappropriate.
It is not what is needed, and what is needed, Adobe has
ignored. |

I then selected some scans
of portraits made in the studio against different colored backgrounds.
When I manually adjust color in a raw scan of a portrait, I ignore the
background color as well as the color of clothing and adjust the color
values to obtain the best rendition of skin tones, letting all other parts
of the image colors fall where they may. Of course, Auto Color does not
know the image is a portrait, so it assumes it should have a typical distribution
of color and reads a whole bunch of color from clothing, and or background,
and adjusts the image according to the overall color content. This resulted
in skin tones that are way off from what they should be. In other words,
don't expect Auto Color to work unless you make stereotypical images of
trite, ordinary subjects. If you make images which vary from the usual,
Auto Color will not recognize the uniqueness of the subject (like a high
key wedding portrait) and will make adjustments assuming it is a stereotypical
snapshot subject. Adobe needs to understand that no amount of programming
can substitute for the skill that comes from knowledge and experience
and a critically trained eye. That is the only way you obtain image excellence.
Programming just reduces everything to the lowest common denominator of
mediocrity.
Retouching Tools
My highest hopes were quickly dashed when I found out that the new retouching
tools were another attempt to substitute programming for knowledge and
skill. The "Healing Brush" is just a version of the old, familiar and
inefficient Clone Stamp, adding a bunch of background processing that
slows it down to a crawl even on a new Mac G4 with 1GB of RAM. The idea
is that you set the Healing Brush's pick up point at a place where skin
tones are ideal and then clone that into an area that has wrinkles or
a blemish, and the underlying lighting and color will be retained. Well,
in many instances, that is not what is even needed.

Wedding and portrait photographers will find the modification
that now allows a Picture Package to contain more than one
image selection a major advantage. |
|
For instance, in shadows under
the eyes, a frequent area that requires retouching, most of the time the
skin is discolored with a bluish or greenish tinge of color and the light
reflects oddly from that abnormal skin. So, I would want to pick up color
from a normal area of complexion tone and clone it into the shadows under
the eyes rather than have the color and lighting appear the same as before.
In another instance I want to clone in normal, peaches and cream skin
tones to a dark, brownish mole I want to remove, so I don't want that
dark, brownish color to be retained.
If the Adobe Photoshop programmers
had consulted someone like myself, who has retouched thousands of photographs
on both analog film and paper as well as digitally, and watched how I
work and asked what kind of tools are needed, they might have provided
some that are useful and increase efficiency. So really no improvement
has been provided, just a modification of the old Clone Stamp that slows
the process down so much that it would take all day to accomplish what
I can do in less than an hour. In under an hour I will make from 1000
to 2000 clicks with my Wacom mouse-if I used the Healing Brush it would
fall way behind and never catch up. I feel that what is offered is unrealistic
and is not what is needed.
Years ago, Zsoft PhotoPaint
had almost a dozen different brushes ideally configured for retouching.
Unfortunately, when Corel bought the program they did not understand retouching
either and did not keep most of them, and my opinion is that neither Zsoft
nor Corel has the excellent color handling and superb engine under their
applications that makes Photoshop number one. But maybe because they are
number one, and have little if any competition, they think they know better
than the user what the user needs and wants. But from the perspective
of an old-time master retoucher, the Healing Brush and related Patch Tool
miss the mark by a mile, and tools we could use and have suggested are
ignored because apparently Adobe thinks they know better what we should
want or need.
Picture Package
The last of the four new photographic features is a modification of the
Automated Function, Picture Package. This will be much appreciated by
portrait and wedding photographers who are doing their own printing. Now,
for any configuration and paper size selected, you can select different
images to be printed within a package. For instance, if you have a package
on 8.5x11 paper with one 5x7 and eight wallets, the 5x7 can be a different
image than the wallets. Once you activate the Automated Function > and
select the layout and paper size, the open image in Photoshop will fill
into all of the spaces. You then click on one of the frames and browse
and point to another image file and it will be inserted in that frame.
This new flexibility will make it possible to satisfy any combination
of print size packages from any of the poses that were taken during the
sitting or wedding.
Why The Upgrade?
The main reason apparently for the upgrade designation from Photoshop
6.0 to Photoshop 7.0 is that 7.0 now runs native in Mac OS X. For many
photographers that is, for now, of dubious value, as many devices, like
some scanners with SCSI interfaces and TWAIN drivers, lack any support
for in OS X. So, my bottom line is that unless the new Picture Package
feature is essential there is no good reason to upgrade. Until I see what
is done with the next version of Photoshop Elements I'm going to hang
with Mac OS 9.1 and Photoshop 6.0 and save $149, thank you. By the way,
instead of Auto Color Adobe would have been wiser just to put the Remove
Color Cast Tool from Elements into 7.0. It is much more useful and effective.
