Vuescan: A review from a non-photographer’s perspective

Dave Farquhar Software , , , , , ,

Vuescan is a third-party scanning tool for most versions of Windows, OS X, and Linux. It supports hundreds of scanners, including those abandoned by manufacturers. It’s probably better than what came with your scanner. The pro edition probably costs as much as your scanner too, but comes with lifetime free updates, so you know you’ll be able to use your scanner for as long as it continues to operate, rather than rolling the dice on manufacturer-provided drivers working with your next upgrade. And you can run it on up to four computers at a time, which is nice.

Full disclosure: I bought this software myself. I was not provided a copy for review, nor am I receiving anything in exchange for writing this review. Now that’s out of the way, and you don’t to have to guess about my motives. Read more

Google is your friend if you have an old scanner

Dave Farquhar Hardware , , ,

My wife bought a scanner around the turn of the century. It’s old, but has always worked well. It’s a Canon LIDE 50, which should come as no surprise. Canon generally makes good hardware. The only problem is that Canon hasn’t made a new driver for it since Windows XP.

I’ve thought of keeping an XP box around for scanning, but wondered if there was a better way. Turns out there is. Thanks to this blog post I know the LIDE 60 drivers work fine, so we can keep the scanner even as we leave XP behind. That’s great, because I hate tossing perfectly usable hardware just because it’s old.

So if you have an old scanner, Google it. There may very well be a close-enough driver out there for it that you can use with a bit of tweaking. And if not, and you don’t mind paying $40, there’s VueScan, which works with 2,400 different scanners and all three (yes, three!) major operating systems. So you can use old weird scanners with Mac OS X or Linux if you want. And $40 is probably less than a new comparable scanner will cost.

Things to look for in a flatbed scanner

Dave Farquhar Hardware , , , , , , ,

David Huff asked today about scanners, and I started to reply as a comment but decided it was too long-winded and ought to be a separate discussion.

So, how does one cut through the hype and get a really good scanner for not a lot of money?The short answer to David’s question is that I like the Canon Canoscan LIDE series. Both my mom and my girlfriend have the LIDE 80 and have been happy with it.

For the long answer to the question, let’s step through several things that I look for when choosing a scanner.

Manufacurer. There are lots of makers of cheap and cheerful scanners out there. Chances are there are some cheap and nasty ones too. Today’s cheap and nasty scanners will be a lot better than 1995’s crop of cheap and nasties, since the PC parallel port was a huge source of incompatibilities, but I want a scanner from a company with some experience making scanners and with good chances of still being around in five years.

Driver support. Much is made of this issue. But past track record isn’t much of an indicator of future results. HP and Umax infamously began charging for updated drivers, for example. But at least I could get a driver from HP or Umax, even if it costs money. My Acer scanner is forever tethered to a Windows 98 box because I can’t get a working driver for Windows 2000 or XP for it.

Umax used to have a stellar track record for providing scanner drivers, which was why I started buying and recommending them several years ago. I don’t know what their current policy is but I know some people have sworn them off because they have charged for drivers, at least for some scanners, in the recent past. But you can get newer drivers, in many cases, from Umax UK.

But that’s why I like to stick with someone like Canon, HP, Umax, or Epson, who’ve been making scanners for several years and are likely to continue doing so. Even if I have to pay for a driver, I’d rather pay for one than not be able to get one. Keep in mind that you’ll be running Windows XP until at least 2006 anyway.

Optical resolution. Resolution is overrated, like megahertz. It’s what everyone plays up. It’s also a source of confusion. Sometimes manufacturers play up interpolated resolution or somesuch nonsense. This is where the scanner fakes it. It’s nice to have, but there are better ways to artificially increase resolution if that’s what you’re seeking.

Look for hardware or optical resolution. Ignore interpolated resolution.

Back to that overrated comment… Few of us need more than 1200dpi optical resolution. For one thing, not so long ago, nobody had enough memory to hold a decent-sized 4800dpi image in memory in order to edit it. If you’re scanning images to put them on the Web, remember, computer screen resolution ranges from 75 to 96dpi, generally speaking. Anything more than that just slows download speed. For printing, higher resolution is useful, but there’s little to no point in your scanner having a higher resolution than your printer.

I just did a search, and while I was able to find inkjet printers with a horizontal resolution of up to 5760dpi, I found exactly one printer with a vertical resolution of 2400dpi. The overwhelming majority were 1200dpi max, going up and down.

Your inkjet printer and your glossy magazines use different measurements for printing, but a true 1200dpi is going to be comparable to National Geographic quality. If your photography isn’t up to National Geographic standards, megaresolution isn’t going to help it.

Bit depth. If resolution is the most overrated factor, bit depth is the most underrated. Generally speaking, the better the bit depth, the more accurate the color recognition. While even 24 bits gives more colors than the human eye can distinguish, there is a noticeable difference in accuracy between scans done on a 24-bit scanner and scans from a 36-bit scanner.

If you have to choose between resolution and bit depth, go for bit depth every time. Even if you intend to print magazines out of your spare bedroom or basement. After all, if the color on the photograph is off, nobody is going to pay any attention to how clear it is.

Size and weight. Some flatbed scanners are smaller and lighter than a laptop. If they can draw their power from the USB port, so much the better. You might not plan to take one with you, but it’s funny how unplanned things seem to happen.

Preserving those new (and old) holiday memories

Dave Farquhar Photography , , , , ,

Sorry, I never got around to those promised posts because, well, I’ve become a genealogy addict. But don’t you worry, this post is relevant even to people who are sick of reading about genealogy.
Mom and I were going through some old photo albums, and some of the photographs were in pretty bad shape. For all the talk about concerns over how long inkjet prints of digital pictures might last, some of Mom’s 30-year-old prints are, well, fading fast. Meanwhile, Mom has some prints that were taken 30 years ago that look like they could have been processed yesterday, except for the clothes the people were wearing.

I remember almost 15 years ago, when a neighbor’s house burned, going through their rescued photo albums, opening up the drenched pages, taking out whatever photos would come out in one piece, and putting them on towels scattered about the house to dry. I noticed that Polaroids are very difficult to get remove intact from sticky album pages, even under ideal conditions. Well, now I wonder if anyone pays attention to the acid content in those album pages and what else might contribute to pictures deterriorating.

But I’m not going to spend too much time thinking about that (why not leave that to the infamous self-proclaimed aristocrat and scientist?) because there’s an easy solution.

Scan those bad boys.

Most people have mountains of photographs, so it’ll take a while, but if you set out to scan a page a day, or a few pages a week on Saturdays and Sundays, you’ll eventually get through them. Burn them to a quality CD–I know among the name-brand discs you find in stores, the most consistent performer you’ll find is Kodak. If you buy in bulk, your best bet is either Mitsui or Taiyo Yuden, which are the two brands that CD duplicators most frequently use. The estimated lifespan under reasonable conditions for a high-quality CD-R is around 100 years. Some of my cheap house-brand CD-Rs haven’t lasted two years. So buy good stuff, and store the discs at room temperature. Don’t put them in the attic unless they’re full of pictures of former significant others whom you wish you’d never met. Remember the basic scientific principle that raising the temperature 10 degrees doubles the speed of a chemical reaction, so in theory, raising the temperature 10 degrees halves life expectancy. Storing your CD-Rs in a closed box in the basement, assuming it’s not terribly humid down there (40% relative humidity is optimal, according to Kodak), would be a good idea.

Actually, that same principle would be just as true for your prints as well.

Anyway, what do you do when the prints have already started to fade? Scan them anyway. Sometimes the scan ends up looking better than the original. If not, then try turning them into B&W pictures. Use your imaging software to convert it to greyscale, then play with the brightness and contrast. You’ll lose the color, but you might very well save the print. In the case of some of the old pictures of me, it’ll be harder to tell that I had blonde hair when I was really young, but it’ll at least be possible to tell what I looked like.

If you don’t have a scanner or you’re dissatisfied with the speed or quality of your existing scanner, I can recommend Canon’s LiDE series. They’re inexpensive and offer a very nice combination of speed and image quality. Most of them get their power from the USB port, which saves you a power outlet. And they’re small and light enough that they can fit into a laptop bag, making it possible to take a scanner and laptop along with you when you visit family and scan some old photos.

Getting those photos into digital form gives you other advantages as well. Some imaging software allows you to add captions or descriptions to the photos. If you’re Linux-savvy, you can set up a nice family website using one of the 12 bazillion gallery programs out there. You can keep it on your local LAN if you don’t want that stuff on the public Internet–you and your family can still enjoy punching through pictures on a strategically placed computer the same way you flip through old photo albums. If you’ve got a nice color printer, you can make as many reprints as you want, and if they fade, you can always just print them again. And while you’re burning CDs, you can burn an extra copy or two and keep them in someone else’s basement. If disaster strikes, insurance can replace most material items, but not the one-of-a-kinds like your photographs. Fortunately it’s easy to ensure they’re no longer one-of-a-kinds.
