This column will attempt
to provide solutions to problems readers may have in getting into and
using digital cameras, scanning, and using digital photographic images
with a computer and different kinds of software. All questions sent
to me will be answered with the most appropriate information I can access
and provide. However, not all questions and answers will appear in the
column. Readers can send questions to me addressed to Shutterbug magazine,
through the Shutterbug web site, directly via e-mail to: editorial@shutterbug.net
or by US Mail to: PO Box 2830, Lompoc, CA 93438.
Q. I’ve read
many articles on digital photography, but none has provided information
on how fast the digital cameras are (i.e., if one were to rate the sensitivity
of their light-capturing sensors, what would that camera’s ISO
rating be?).
Are digital cameras more sensitive to light than a 35mm camera with
ISO 100 film? Is there a difference in sensitivity in providing color
vs. black and white images (or do these cameras provide only color)?
I realize that there are many variables, such as f/stop of the lens,
but I’d appreciate your thoughts on this.
Russ
A.
The light sensitivity of digital cameras varies between brands and models.
Many of the under $1000 cameras have a default equivalent of ISO 100.
The more expensive and full featured often provide a selection of sensitivity
ratings commonly 100, 200, 400 ISO equivalent. The more expensive and
professional cameras that are intended primarily for press photography
and similar uses have ISO equivalents to as high as ISO 1600.
Lens speed and shutter speed ranges are pretty much on a par with typical
35mm cameras--the more expensive have faster lenses and a greater shutter
speed range. Today, these cameras essentially capture in color, but
it is very easy to convert or desaturate a color RGB image to make it
gray scale. Specification for ISO equivalent sensitivity ratings for
various models of digital cameras are posted at the web sites of most
of the manufacturers like Canon, Olympus, and Nikon, etc.
Q. I am going to
create a web page and would like to enhance it with photographs of the
town I live in. I am thinking that a digital camera would be appropriate
for this, because I imagine that the images can be transferred directly
into my computer, then formatted to fit the web page.
What digital camera do you recommend for good quality photographs? What
software would I have to purchase? My computer has Pentium II and runs
Windows 98.
Are there any other things I need to know before I invest in a digital
camera? Thanks.
Tom Reeves
A. Just
for use in web page creation, the inexpensive, under one megapixel digital
cameras are sufficient, and the cost for some 640x480 pixel models is
between $200 and $300. Most are sold with essential software to acquire
the images, as well as an easy to use image-editing application like
MGI PhotoSuite II or Adobe PhotoDeluxe 3.0.
However, if you already have a 35mm film camera and your needs for web
pictures is limited, I would suggest taking the pictures with 35mm color
print film and having Kodak processing done with the addition of a Picture
CD. This provides access digitally to the images as the film is scanned
and files of the images created on a Picture CD disc. The Picture CD
disc also has basic software on it which allows simple access and editing
of the pictures on your computer.
You might check the Kodak web site for locations near you for Picture
CD processing vendors.
Q. My question has
to do with inserting a digital image in powerpoint presentations.
My Mavica 83 is capable of taking still shots with audio included as
well as movies with audio included.
It seems to save the latter as mpeg files and I can successfully insert
them into the powerpoint presentations. However, inserting the still
shots with audio (voice) is another matter. It seems to save those as
jpeg files and so when I insert them all I get is the picture (and no
sound). Am I doing something wrong? Is there something I can do to allow
my powerpoint presentations to take full advantage of my new camera’s
capabilities?
A. First
I will assume the Mavica saves the sound information relative to still
images as a separate file, so you will need to locate and identify the
sound part of the data for the still pictures. It should be in one of
the two standard sound formats like .Wav or less likely in midi format.
I have not used powerpoint in some years but I believe sound files can
be inserted into a presentation and scheduled parallel with image files.
and, considering PowerPoint is Microsoft, the standard sound file format
.Wav is supported. You might also check your Sony Mavica Owners Manual
specification to see in what format the sound files are recorded.
Q. I was wondering
about the new epson stylus photo 1200--is it better than the stylus
photo EX? I will be using it for making 11x16 prints for an art fair.
and, about the longevity of ink jet prints, would laminating help this
problem, and if so do you know the make and model i would need? Thanks.
Byron Moore
A. You’ll
find two main advantages with the 1200 over the Ex. First it prints
13” wide paper, two inches more than the Ex. Second, it has finer
nozzles down to 6 picoliters, and varied dot size, which provides a
sharper reproduction of detail, as well as smoother tones and gradations.
Finally, it is faster printing at maximum resolution than the EX.
Archival inks and papers are now just becoming available for the Epson
printers. The papers I have used are 100 percent cotton rag and look
like fine watercolor stock. The names are Liege and Concorde. The Luminos
photo company is distributing Lyson inks which are archival. In addition
there is a very new pigmented ink just out. All of these supplies are
available from MIS. You can obtain full information, prices, and order
from their web site at: www.missupply.com
Q. I have been accustomed
to printing in the darkroom, making four 31/2x5 or two 5x7 pictures
on one sheet of 8x10 paper. I am unable to do this in Photoshop, but
there ought to be a way. Can you tell me how? I use Photoshop 5.0 and
an Epson Stylus photo EX.
A.
First of all, check all of the software you received with the Epson
Stylus Photo Ex. That function may be supported by one of the bundled
software utilities. It definitely is with the new Epson Stylus Photo
1200, as part of the NewSoft application bundle that comes with the
printer. You should have a CD you got with your printer, take a look
at what it has on it.
Then, if you plan to upgrade to Photoshop 5.5, which just came out,
that print image formatting feature is now included under the file menu
heading Automation.
Q. I am researching
the digital photography market and could use an expert’s advice.
I have come across many opinions in my research and have noticed that
many people like the Sony Mavica. Since this camera uses a floppy disk
to store its memory it is less efficient than other cameras which use
flash memory (e.g. smartmedia and Compact flash). Which format of data
storage do you see prevailing farther down the road of digital photography?
David Gaspar
A.
I don’t have a crystal ball for this one. Unfortunately the superior
technology, reason, and logic do not always prevail when it comes to
what succeeds in the marketplace. Personally I would favor Iomega’s
Clik disk/drive as being the most efficient and effective camera image
storage medium. However, as far as I know now, Iomega has only been
able to convince one manufacturer of the advantages, and that’s
Agfa. Now Sony is in the game with the Memory Stik, yet another flash
memory type media, making three distinct formats for that type of storage.
This problem, and it is a problem when there are so many competing formats,
may go unresolved as have the attempts to replace the very obsolete
1.44 floppy disk. In other words, no resolution any time in the foreseeable
future. For now, that is a factor of less than ideal efficiency and
some inconvenience, but in the long run it may provide the opportunity
for some currently unknown solution to emerge and become a de facto
standard. Ideally a portable storage media which would work as well
for desktop computers, laptops, and notebooks, as well as digital cameras
would be preferable. If it weren’t so expensive, IBM’s MicroDisk
with 340MB in a half size PCMCIA type card would be promising. considering
the current level of market competition, and the inclination of companies
to remain proprietary because they believe they have a better mousetrap,
makes the emergence of any standard, a rather remote hope.
Q. I recently got
a 35mm widelux camera and was wondering if any of the sub $1000 film
scanners can handle the 24x59mm negatives. I could always get a flat-bed
scanner I guess but are they as good as the dedicated film scanners?
I get the impression that the new HP scanner could do what I want but
I don’t think it will work with my computer--a Power Mac 9600.
Flor Collins
A.
I am afraid there isn’t any such animal. The less expensive desktop
35mm scanners function by moving the film on a carriage past the CCD
element, which is controlled by software on the computer and firmware
in the scanner. None of the models like Nikon, Canon, and Minolta that
I’ve used have had an option to scan a panorama 35mm film image.
To get decent results from a flat-bed for that size and format film
you’d at least need a good 1200 x2400dpi unit with transparency
adapter like the Linotype Saphir Ultra 2 I recently tested. At the latest
street price it is at a little above your price, but an excellent all-around
scanner with superb software. Ideally the next level up, like the Linotype
Saphir HiRes, would do an excellent job, but it is a much more expensive
proposition.
Incidentally I tested and reported on the S-20 HP PhotoSmart. It is
a decent scanner, providing very good performance for the money. However,
I did not see any support for scanning non-standard format 35mm film.
And, it is strictly a USB interface scanner, so you would have to have
the latest Mac OS and a USB interface a adapter installed.
Q. A friend of mine
just recently introduced me to Shutterbug. She has loaned me the July
issue and I think the cover image is just wonderful. I have the Photoshop
5.0 LE version and have invested a lot of time experimenting with the
artistic filters to come up with a nice watercolor effect. I’ve
come up with some interesting effects, but nothing that comes close
to your results. The “On The Cover” paragraph tells how
you applied three different Photoshop filters and then merged them,
but it doesn’t give the specifics. I am hoping you will be willing
to tell me how to duplicate this effect. Thank you in advance for your
help.
Daphne Newman
Baton Rouge, LA
A. First
of all, you probably will not want to “duplicate” what I
do exactly. The reason is that when I do these effects, I find I do
it differently for each image. That is because different kinds of images
process differently and are affected distinctly by each filter.
So, the basic idea is that each filter by itself is too distinct, too
obvious. I usually choose three. One that applies a background effect
with a lot of texture, like Notepaper and Under-Painting. I apply this
to a reduced size of the image.
1. Before starting set the image resolution to 300 or 400, and then
save a copy. With the copy open for background filter I resample the
image to 100dpi first. This makes the filter effect very bold. After
applying the filter I resample back to the 300/400dpi, and save the
filtered effect as a new file. Usually I apply some sharpening to this
image before saving.
2. For the intermediate filter, I also use a reduced 100dpi file size
of the original copy image. Then I will try various paint effects like
PaletteKnife, Pastels, WaterColor--and sometimes I will use similar
filters from other programs like PhotoImpact, Corel, or Micrografx.
Sometimes I’ll try running three or four filters before finding
one that has the right effect on the image--this varies depending on
how much detail or lack of it there is in the image. Again I usually
apply sharpening to this image before saving. Once I have the filter
effect I like and apply it, I resample back to the full 300/400dpi size,
and save this as another new file.
3. The final filter effect is one that emphasizes fine detail, like
Pen&Ink, PaintDaubs, Etch, Scratchboard, which I apply to a copy
of the original copy image at full 300/400dpi usually, or just a slightly
reduced size of 200dpi. Again once I’ve found the right effect
I apply it and save as a new file after resampling back to the original
dpi of 300/400.
4. Putting the three images together is also a bit different for each
image as to how the blending is set. First open the first of the three
images. Then open the second, and Select All and use the Edit Copy command.
Close the second image. Then paste the copied image into the first image.
Using the Layer option dialog window, I start by setting Transparency
at 50 percent, and move it back and forth until I see a blend of the
two image effects that is balanced. Then I open the third filtered image
and select All, Copy, and paste it on top of the No. 1 and No. 2 that
are already blended. Next I set the Transparency, this time usually
between 20 and 30 percent.
5. My final finishing involves merging the three layers, and saving
the image as a single new TIFF file. However before I make the final
save, I open the Levels Adjustment dialog and equalize the gamut by
clipping any blank area from either end of the histogram. Next I usually
apply one more mild application of sharpening, this time with the Unsharp
mask filter. Usually that’s all I need to do. But, occasionally
these layered, blended images lose some color brilliance, so I will
open the Hue/Saturation Adjustment dialog and increase saturation. Most
of these effects images I create are begun with a 20 to 30MB scan of
a 35mm image. I usually resample the image a little larger after all
of my work is done to print the image at 12x18” on 13x19”
paper at 240dpi.
Q. If possible would
you please let me know if the Linotype Saphir Ultra 2 scanner is the
same as the Heidelberg Saphir Ultra 2 scanner that appears on the B&H
web site? The price is considerably less at B&H--MAC edition $1227.95
as opposed to your ESP of $2749. I have subscribed to Shutterbug for
many years and love your digital info. I am a commercial photographer
and will get this scanner or the Epson 800 with trans adapter and the
Epson 1200 printer to proof my 4x5 to 35mm studio work. Which scanner
would you recommend? Thank you.
Dick Fellows Photography
Philadelphia, PA
A. Confusing
yes, but Linotype Hell and Heidelberg are the same company, and the
Saphir Ultra 2 is the same scanner. Just after I submitted my report
to Shutterbug I received an announcement of the price drop. The Saphir
Ultra 2 definitely has better resolution than the Epson 800. However,
I personally find the Epson version of SilverFast a friendlier and more
effective software package. Although the software for the Saphir is
also excellent, it is just friendlier to pre-press use than photography.
Q. I write a general
interest news column for the Chicago Tribune and have recently been
exposed (I’ll bet you’ve never heard that pun before) to
digital photography in the wild. To wit, my father, a long-time photo
hobbyist, brought his first digital camera along with us on a family
reunion/vacation and took literally hundreds of shots, all of which
were saved to floppy disks that we quickly uploaded into the hard drive
of a laptop computer that was also along on the trip. While we were
there and it was all very fresh and interesting we culled the images,
had our own little slide shows, etc. It was a vast improvement in vacation
photography in every way but one--the resolution isn’t as good
as with conventional photography. But I became fairly convinced that
despite the quality compromise, digital will replace conventional (is
there a better term) just as home video have replaced home movie cameras,
cassettes have replaced reel to reel. In 10 years, maybe 15, surely
20…as the cost comes down and quality goes up, digital will be
every man’s standard. Conventional photography will be the realm
of the hobbyists and professionals.
Long buildup to a short question: Do your experts agree? What are the
percentages now and how are they changing? Have you written any articles
on this I could get hold of?
Eric Zorn
Chicago, IL
A.
I quite agree with everything you have said with but one exception.
I don’t think that it will take as long as you suggest. The reason
is that this fall’s releases of new digital camera models are
characterized by the same quality/price inversion as is true of most
of the “computer” products in the market. The resolution
limitation you noted is no longer, and the prices are comparable to
film cameras with similar features. The limitation you noted about resolution
is relative to the fact the Sony Mavica provides the convenience for
some of saving image files on floppy 1.44MB disks. Current, even entry-level
digital cameras produce file sizes too large to conveniently store them
on floppies. And what’s more, Apple has abandoned the floppy disk
media, as it should be with PCs if agreement can ever be reached on
which media standard will be the replacement.
At the current sales’ rate worldwide, combined with the growth
rate digital cameras are enjoying (last year 102 percent), they will
have far outstripped the sales of film cameras in just about every category
by this time next year, especially if holiday shopping is good in ’99
and the economy remains bullish.
Q. I read with interest
your reply to Mr. Reilly in the Oct. issue of Shutterbug regarding how
much resolution is really needed to scan for a 5x7 print into PhotoDeluxe,
because I was having the same problem--namely, scanning 4x6 prints with
the highest resolution possible on my Plustek scanner and then having
everything freeze up from indigestion. However, could you clarify the
numbers for me cited in Joe Farace’s column, same issue, which
says that Seattle FilmWorks “Hi-Res Pictures On Disk” service
is scanning at 1.5Mp (1500x1000 resolution). How do these numbers compare
with my scanning resolution of, say, 300dpi and wouldn’t 1.5Mp
be overkill--or am I still confused? Thanks for your help.
Henry J. Fischer
Dripping Springs, TX
A.
I think the confusion is not helped by Seattle FilmWorks coining a new
measurement standard for images (Mp). Aside from that, let’s first
start with what you say you are doing. First of all, you did not specify
what that “highest possible” resolution is you are using
with your scanner. However, as a general rule there is no point in scanning
at a dpi higher than what you plan to print (but not the printer’s
resolution). If you are going to print with an image resolution of 300dpi,
which is appropriate for small prints, then set your scanner at 300dpi,
no higher. If you are scanning a 4x6 the resulting pixel dimension at
300dpi will be 1200x1800 pixels, and the file size in 24-bit color will
be 6.348MB, which is a bit larger size than the Seattle FilmWorks 1000x1500
pixel size which would produce approximately a 4.1MB uncompressed file.
For your information your 4x6 at 300dpi would produce a 2.3Mp (megapixel)
image.
These sizes above should not be a problem causing a freeze up with Adobe
PhotoDeluxe. Deluxe does have a maximum image size limit I believe,
but much higher than the sizes specified. Your freeze was probably caused
by actually choosing a interpolated resolution much higher than 300,
which could produce a file size far too big for Deluxe to handle, and
one that will bog down your system.
Q. I am in the process
of purchasing the Sony CRX 120 E. Things take longer here in Mauritius.
It is my intention eventually to send my CD-ROMs to prospective buyers,
for them to see my work and portfolio. In terms of simplicity, what
software would you recommend that I use, if the intention is for the
Art Director just to insert the CD in the drive without too much worry?
Some picture libraries may not have Adobe, Photosuite II. Simplicity
is the key here. Thanks.
Perry Joseph
Mauritius
A. There
are several possibilities, but the one which at this time assures the
best reproduction of your work, is cross-platform so it can be opened
and viewed as easily from a Macintosh as a Windows PC, and the reader
that can be freely distributed with the CD is Adobe Acrobat 4.0.
