Window Light in the Early Evening. Some thoughts about scanners.

Scanned from a Kodachrome. Shot on a Canon film Camera with one of the 
First Tamron SP normal focal length zooms.  Something like a 35-80mm.
Scanned on a cheapo flatbed scanner.

I'm going through old slides and making scans for myself. I've owned Nikon dedicated film scanners (both medium format and 35mm) and I've had plenty of film drum scanned but for some reason I prefer to do my own stuff on a cheap, non-prestigious, Epson flat bed scanner.  We're talking here about a scanner that currently sells for around $180.

The machine is smaller than other scanners I've owned and sits on the right hand side of my desk in a constant state of readiness.  The machine's full name is Epson Perfection V500 Photo.  It won't scan 4x5 inch film but will do most conventional medium format formats and it will scan 35mm transparencies and negatives.  Film  holders are supplied for 120mm film and 35mm film in most of its permutations.

The slide above was taken in mixed light.  It's a Kodachrome 64 slide. How difficult and time consuming is it to make an image like the one above?  Let's see.  I put the slide holder on the glass surface of the scanner.  There's guide indention on the scanner body that matches up with the holder. Very straightforward.  The slide holder has four squares in which to drop your slide, still in slide mount. Close the top, open the Epson scan software, click in the film type (trans or neg; color or black and white) decide on the bit depth you need (24 or 48) determine the size you'd like the the image to end up at (dimensions and DPI) then hit preview.  You can zoom in on the image in the preview window.  Once you see the image large you can more accurately crop and adjust.

I go into the curves menu and set the white point and black points on the represented histogram.  If the color needs to be tweaked I go into the color adjustment menu and play around with the R, G, & B sliders till I get what I want.  There are also menus for saturation, contrast and exposure.  In the curves menu I can also set how I want the toe and shoulder of the film to look = soft, rounded curves or straight overly accurate curves.

When I have everything hunky dory in the different corrections menus I go back to the main menu and set the amount of unsharp masking I want and whether I want the canned "color restoration" to kick in.  Then I hit "scan."

I can't use the Digital Ice dust removal with traditional black and white film or with Kodachrome slides. Something to do with the physical topology of the film so I leave these controls unchecked.  It does mean that I'll inevitably be doing some retouching to the files to remove dust spots before I use the images.  So, a straight scan of a film from a slide done at 6000 by 4000 pixels (final size) takes about three minutes.

I hear all kinds of nonsense from people about what's needed  for good scans.  There is a camp that believes flat bed scanners are incapable of doing usable work.  There's another camp that's seen good scans from flat bed scanners but believes that you need to pull slides out of their cardboard mounts and coat them with oil before you can get a good scan and then there's the group that believes the scanners may be usable but only when paired with really good and really expensive software.  Almost as though you have to pass an initiation to join in the cult of scanning.

I don't fall into any of those camps.  I routinely scan all kinds of stuff on the Epson and I'm always able to use the output to deliver jobs or to make prints from it for shows and portfolios.  If you are unable to get a good scan on an Epson V500 or V700 I believe you might be over-thinking the process.  The most important thing is to explore the software thoroughly and trust your perceptions.

The native resolution of the scanner is 4800 dpi.  That means a full scan of a medium formatsquare negative or trans scan is 12,000 by 12,000.  And you can make that scan as a 48 bit file if you are willing to save it as a Tiff.  But I'll tell you right now that this will be one monstrously big file....

If my math is correct you should be able to generate a medium format scan that measures 40 by 40 inches at 300 dpi.  That's pretty darn good.  35mm scans clock in at about 7200 pixels and can make a print, at native resolution of the scanner, equal to 16 by 24 inches at 300 dpi.

My needs aren't that radical and my expectations are that the machine will deliver files for good display of 35mm stuff on the web or on an iPad while the files from medium format film will be good for prints up to 20 by 20 inches. Given that I've been sharing images with you for years which come from this scanner, without any complaints on my part or on your behalf I'd say I'm get pretty good performance from a $180 device that comes with its own software drivers.

I have used Silverfast and VueScan and I like the bundled Epson software best. The other two may be wonderful for people who are really, really interested in scanning and it might get you an extra one or two percentage increase in quality but I'm happy with the straightforward simplicity of Epson's solution.  I am running it on OS 10.7.4 on a MacBook Pro.  Takes a couple of minutes to launch and then it's fast and crash free.

The scanner will allow you to load four mounted slides for scanning and let you preview the four, crop them, color correct and size each on individually and then allow you to batch scan all four without mediation.

If you have a big inventory of  MF slides, can't afford to just dump them on the desk of a scanning supplier and write a check, and are mostly interested in printing and sharing the images you should look at a machine like this one.  If you need ultimate image quality for a big ad client you'll be better off having service drum scan your image.  At least then you've covered part of your ass when people start looking for who to blame in the production phase.

In all seriousness though,  I used to hear that clients would never use digital images from digital cameras for XXXX reasons.  Then I heard the same thing about cheap scanners.  But I've got to tell you it's just not true.

Here's the drill:  launch app > install correct film holder > choose film type > choose preview > Choose zoom > crop > color correct >  choose size (geometrical) and bit dept (24 or 48)  > engage restore color  (matter of taste) > push scan.  A window will pop up asking you where and how to save the file.  Once scanned take the image into PhotoShop and retouch out the dust and scratches in the method of your preference.  Scan one time as big as you ever think you'll need and resize and save copies for other uses.  Kinda fun to be able to engage your film files for the greater good of the universe and your artistic sharing.














When your early work becomes vintage...

San Antonio. El Camino.

"Had we but world enough and tyme..." (To His Coy Mistress, Andrew Marvell). We're all subject to the passage of time.  No matter what profession you've chosen there will come a time when you look back and see where you came from. If you are into computers and you are of a certain age you'll talk about the lure of that Kaypro computer whose 9 inch green screen boasted a whopping 80 characters per line.  Ah, 1982...  

If you are a photographer you'll look back, sometimes in wonder and sometimes wincing, as you look at the slides you made with different films.  Fuji survived the slide film cold war and Kodak didn't but the images I shot on the early versions of Fuji are faded and mottled while the images I shot on Kodachrome are still exactly as they were when the little yellow boxes came back from the lab.

What I never remember until I scan them is just how low saturation Kodachrome 64 film was.  Certain colors popped (red) and certain colors didn't (blues and greens).  When Fuji Velvia came out I think it was widely embraced by photographers just because they were finally able to see real, honest to God, over the top color saturation. Our films helped create our visions of what was right, colorwise.

In the late 1970's and the early 1980's I felt drawn to San Antonio's downtown.  I'd pack a small camera bag with a camera body, a couple lenses and ten or twelve rolls of film.  I always packed the same film, not a mix. One day might be Tri-X black and white and another day might be Kodachrome 64 but always only one film type per day. It was easier for me to get my head around one linear way of thinking that to shift gears all the time.  And it was expensive, when using 35mm, to decide halfway through a roll of film that you really needed to switch to a different type. 

I don't know what I was looking for as I walked around the streets with my camera. I was in the advertising business at the time so it was more like a hobby than something I could rationalize as a business.  I guess I was trying to preserve the city from change.  I might have been documenting something different than that.  I may have just been emulating the documentary photographers I admired from books and magazines. Now, when I walk the streets of every city I'm looking for little glimmers of human scale and human touch to juxtapose against the constant change and the secure walls of progress.

I like walking with a camera.  I suppose I am Calvinistic enough to require some sense of work or duty be attached to the pleasure of walking so I bring the jewelry of my professional along when I amble, the idea being that I'll see something spectacular that will make its way into my portfolio.  But mostly the images go to storage.  In the film days they went into archival plastic sheets and then into a filing cabinet.  Now they go into Lightroom and onto DVD's.  A copy remains on a hard disk or two but until I started sharing the work on this blog they contributed very little to justify the time and expense of their creation.

But now something interesting is at work.  My earliest photographs show my cities and my life as it no longer exists.  Now they are documents of my own history.  As I looked through a selection of several thousand images of San Antonio I am shocked at the buildings which are now gone, the blue capped skyline that was once open transparent now cluttered with buildings and the same sky dingy with the dust and traces of our car culture.  My work has become a history of a city in endless transition.  And all cities are in endless transition. Favorite restaurants gone.  The barbershop that was there last year now a Starbucks...

When I look at the red El Camino I see vintage.  Just like the "vintage" button in Snapseed or the digitally random decay of Instagram, only this is the real thing.  The film that the intentional de-evolution of digital files is based upon.

I used to think the same nostalgic vintage-ism couldn't happen to film since it would decay, it would only perish or exist, fully realized.  But I've also spent time looking at files from each generation of digital cameras and I've seen the progression from primitive to polished. From unsharp files filled with noise to the latest plastic wonder files.

But my real interest has nothing to do with the technical progression of the craft and everything to do with memory and the encapsulation of time as a trigger for future memories. For looking back to see the patterns of life.  A proof that things were as we say they were. A time when we thought we knew everything and would live forever.  

There's an arc of time for every artist.  A time of power and experimentation and a time when you become culturally invisible.  So much of that acceptance and then lack of acceptance is contextual and style driven. You exist within your current milieu.  When you are young you are hooked into current culture.  Everything you do is a reflection of the mass culture you are surrounded by.  Whatever you create references that mass culture so you are at once inside and of the culture.  That gives your work whatever relevance it has as it's foundation.  You add the interesting twist.  Or you don't.  A generation loves Instagram because, well, the generation loves Instagram.  Another generation loved the black and white output of Holga cameras, in part because that's what everyone in the generation was experimenting with and, well, you know, it's really all about peer pressure.  Like smoking cigarettes.

The rising ethos swirling around my early years as a photographer were all about street photography and so I swam in that pool.  No better or worse than most of my fellow photographers. 

But as you live through cycles (be they economic or artistic) you understand that each fashionable style is a short lived romp through the pet rocks and tattoos of mass culture and very little, outside of a few exceptional examples, withstands either the test of time or our own attention spans.  Eventually it all gets sent to the virtual landfill of dozens of neglected hard drives or optical disks and then, by sheer weight of its every increasing bulk, the whole collection becomes too hard to deal with. Too ponderous to browse and it is increasingly ignored in deference to whatever the new trend is.

How else to explain the mass hysteric migration from camera to camera or from web hero to web hero? From big sensors to small and back again.

I've tried to put my finger on what it is that makes digital different from all previous processes.  Across all platforms including writing, photography, music and video.  I think I finally understand.  There is nothing intrinsically different about capturing the images, thinking of the stories or creating the melodies.  But the efficiency of the process makes each field destructively productive.  We are hell bent of the process of creation but without any commitment to the back end of the process.  We're in a constant race to create more and more to the exclusion of savoring each additional step of the process. There is less planning and concepting but more button pushing and cataloging.  Gone, seemingly, are the days when we'd labor for hours to get the perfect print---in digital or analog.  Much easier to slap a 2000 pixel rendition onto the web, share it with several thousand people you'll never meet and move on to the next act of manic production.

It's an evolving experiential process.  I'll readily admit to being behind the curve but I think there's tremendous value in curating your own images, editing them down the way a chef simmers down a sauce to concentrate its taste and power.  I think it's a difficult and rewarding task to go beyond default button pushing and to interpret an image onto paper in a unique way and finally, it's tough and socially significant to pull together a show of images and manifest that show for a public and real audience.  It might be something you bring to fruition only once every ten years but the power of purpose of having a show in a gallery or other space can imbue the artist with a level of insight and inspiration that's gone AWOL as we participate in the process of exaggerated productivity for the sake of-----productivity.

For me this blog, from time to time, fills the void between shows and lethargy.  I put images here to share them as well as to illustrate articles.  But in effect I am robbing the power of a concentrated showing of actual images (paper) in exchange for the very short term buzz of knowing that at least people are seeing the images.  And in a sense it's a very destructive cycle.  The web can be art gallery crack.

So.  Today I realized that some of my images have become vintage.  The rest of them will do so over time. So will yours.  Even if you are only 24 or 30 years old the process has already begun and the only ways to escape the process are to constantly change with every trend that rears its peacock feather festooned head, stop shooting altogether or accept that you've found a style and subject matter that work for you and you alone and to keep doing exactly what that is until you drop over dead.  It's an interesting way of being honest to your own vision.

In the end it's about making your artist self happy.  Or at least honest. If you are in this because you like the cameras it's okay to just ignore this post.
