p.1 #4 · how to scan and process black and white neagtives | |
Well, for a dozen rolls, it's hardly worth getting a dedicated film scanner, that's for sure. As I remember it, the CoolScan was around $1500, and the roll adapter was another couple-few hundred bucks. The main reason I got the CoolScan in the first place is that I'd realized I was going to want to digitize some day back in the 1990's and started ordering my hand-rolled-from-bulk 40 frame film rolls developed without cutting into strips. Much of that film was Fuji Velvia, which has a high density.
Freakin' OS upgrades suck for scanners. I had a spendy HP flatbed scanner I bought in 1996, and HP decided to charge $200 for the software upgrade for XP. Between the fact that the old one was SCSI with FireWire being out, and the newer scanners having film capabilities, I ended up parking the pig and buying a new scanner -- guess what I bought first -- a $99 CanoScan because I needed something fast for paperwork!
Epson is really good about supplying updated drivers for free. I've moved dozens of bits of Epson hardware between three major OS upgrades over the years without once paying for a driver upgrade, but for scanner software packages it sucks because you only get the driver -- The OCR, PDF generation, and DigitalICE software is not downloadable! I gave up a few years ago, and I just keep a couple older boxes around permanently fixed in older OS'es without ever patching or changing anything and the partition saved off to my RAID just so my old printer and scanner software works somewhere.
Anyway, I checked into things a little more and had to stop by my office since I last posted anyway. The Epson scanner I have is the Perfection 4870 Photo. 4800x9600 and rated 3.8 D-Max. The resolution isn't anything special today (your $99 CanoScan is the same), but one pays for D-Max getting over 3.4, that's for sure.
The closest thing to the 4870 in the current Epson line-up is the Perfection V700. The V700 boosts the d-max to 4.0 and offers a mechanical step interpolation to boost the res to 6400 x 9600. If that works anything like the mechanical interpolation on the CoolScan, it takes an extra lifetime to scan things and IMO isn't worth it. The street price on the V700 is around $500 -- I remember paying about $400 for the 4870 on a good deal.
However, in looking at the current Epson lineup, I see they have the Perfection 4490 with 3.4 d-max rating, 4800x9600 dpi optical, digital ICE, and negative holders for $149 list including current $30 rebate. Rated d-max of 3.4 and digital ICE bundled is a heck of a deal for that! For another $50 you can get the V500 which boosts the resolution to 6400 dpi and has an LED light source. Wow, photo scanners have improved price-performance dramatically in a couple years. I see a V500 may be in my future.
I looked up your Canon scanner, and see it is rated at a 3.4 d-max. I take all the consumer scanner d-max ratings with a grain of salt, not as bad as vacuum cleaner horsepower ratings, but in the same class. For some reason drum scanners with the same d-max ratings always seem to have noticeably better actual range.
On the other hand, old film snap shots, even silver process B&W isn't likely to justify the bucks for a 4.0 dmax scanner. Again, my desires are driven in large part by relatively new Fuji Velvia film.
Film grain is a matter of taste. My personal taste is that film grain is a limitation of the technology, and one thing I like about DigitalICE is that it wipes out film grain well. I'm sure that is offensive heresy for some of the people here, and I can truly understand the nostalgic desire to have it come through -- but, you can always add back in film grain after sharpening using Photoshop. (Whoo, I bet that is heresy too...)
In summary, unless you want a better flatbed scanner for future / other stuff, what I'd do is scan all the negatives on your CanoScan, decide on some frames that are most precious and for which the negatives seem best exposed and preserved, and try out a service with a drum scanner for those and see if you get noticeably better results -- only you and your siblings can make the value judgements involved there. I'm afraid I can't help you with the service unless you live around Minneapolis as I use a local service bureau for the limited scanning work I do where I can't handle it (large prints.)
