An acquired taste?

I’ve gone through ups and downs while evaluating this new inkset. At firt I thought it was really cool, then I realized it was just coincidental color still in my system. Then I thought it wasn’t all too different from the images that I can make with the ABW mode on my 3800. Next I was feeling really unsure about the look of the darker tones in the piezography images (the reddish warmth was quite different than what I was used to and struck me as rather odd). But now for the past couple of days it has started to grow on me once again, kinda like an acquired taste. Over the past few days I’ve been combing through some of my favorite b/w images and printing them with the new inks. I’ve already had to refill one of the cartridges and I’ve only been using the system for one week now. Tonight I came across this image that I took at the Guggenheim Museum back in 2005.

I really enjoyed the time I had at the Guggenheim that day, they just happened to have an exhibit of Robert Mapplethorpe’s on display when I was there. I knew that Mapplethorpe had caused quite some controversy while he was alive, but didn’t really know too much about it. Well I can certainly see why a bunch of stuffy old conservatives would get all bent out of shape by some of Mapplethorpe’s photographs. While I was able to get by some of the more difficult to appreciate homoerotic images, I was at the same time blown away by the beauty in so many of those prints. It didn’t really matter if they were of flowers, a statue or a person there was just so much artistic verisimilitude in his work that I found inspiring. I recall seeing for the first time a modern highly techincal large format platinum print. Having become used to the near perfection of Ansel Adams style of printing with deep blacks (think later versions of Hernandez) and rather strong contrasts, it was rather astonishing to see soft warm radiance in those Mapplethorpe prints. At the time it also reinforced in my mind that not all photographic worth should be tied up in trying to approximate the air dried fiber based glossy look. Producing an image with our modern inkjets with the reduced dmax and acuity of the best fine art matte papers produces a result than can at times be not unlike what I saw that day at the Guggenheim.

The new inks that I’ve been working with have a distinct look, they ought to provide me with the chance to produce some of my own soft, warm, radiant prints.

I’ve been really busy lately!

Well life has been very full for me in the past few weeks. I’m working like crazy at my regular job, early mornings, and even working on the weekend. Its not so bad though, because I’m doing stuff that is challenging and kinda fun. At the same time though some of it is pretty hard and requires tons of abstract thought and the type of problem solving required to integrate many conceptual components that only exist in my head (such is the life of a software designer). On top of all the work that pays the bills I’ve also been pretty wrapped up in exercising some of the new photo gear that I’ve received over the past couple of weeks.

Firstly I got a new lens (I’ve convinced myself that I needed to evaluate it). The Nikon 14-24 f/2.8 wide angle zoom lens is the newest and quite possibly the best wide angle lens available short of the legendary 21mm ZeissĀ  Distagon. The lens is rather large and heavy, and the front lens element is huge and bulbous. But it does take some pretty darned nice photos. I don’t have anything particularly worthwhile to show from it yet because I just haven’t been able to shoot without outside of my driveway, or in the house in the evenings. My initial batch of comparisons against my Nikon 12-24 f/4 show that the new 14-24 is very impressive in the corners (the weakest spot of the 12-24). In all likelihood I’ll wind up keeping this lens, even though it is so expensive and not quite as wide as the 12-24. The photo that I’ve included with this post is one of the few photos I’ve shot at 12mm that I would consider successful. At the time I was on a moving ship, so that along with the subject matter rendered the somewhat weak corners moot.

Part of the reason why I haven’t had as much time to shoot with the new lens is that I also have been experimenting with a new printing system and new papers. I mentioned a few weeks ago that I got a new Epson 1400 printer. This is a color inkjet printer that uses Epson dyes. However, a couple of the black and white inkjet gurus like Jon Cone and Paul Roark have discovered that this printer really excels at b/w when using dedicated monochrome pigmented inks. Now I’ve been hearing about how wonderful Cone’s piezography system has been for years and have really wanted to get a chance to try this out for myself. The combination of the economically priced 1400 and the great things I was hearing about piezography inks using this printer finally convinced me to take the plunge and purchase the Piezography Special Edition K6 inkset for the 1400.

The new inks arrived on Monday along with two sample packs of Cone Studio Type 1 and Type 2 papers. Normally the Piezography system for the 1400 is only available as a CIS system. I didn’t really want to use a CIS system because my wife and kids will also need to be able to swap out the b/w ink cartridges and replace them with the color ones. Luckily MIS sells a set of refillable ink cartridges for the 1400 (for how much longer I’m not sure though). This brought the cost of going to a dedicated monochrome inks to be just about $400. This is pretty steep considering that the printer itself only cost about $200. Prices for everything are just ridiculous nowadays. Yesterday I went to order 2 special pens for writing on CDs. The cost of the pens was $8, the cost to ship them to me was $9.00. I canceled the order so Icould wait ’till I was ready to order something else so I could combine shipping costs.

Filling the carts with the Piezography inks was fairly straightforward. Though I had some trouble with using the backfill adapter to suck out 1cc of ink inorder to remove air bubbles from the cartridge. I was a little worried that there might be problems with the chips on these refillable cartridges since they were all third party items. But everything worked perfectly well after installing the new carts (we’ll have to see if things go so smoothly when it becomes time to refill the carts). I ran 2 cleaning cycles on the 1400 waiting to get all nozzles firing without any gaps. This proved to be more difficult than I expected because the number 1 piezography ink is so light that its darned near impossible to see. So I ranĀ  fourth cleaning cycle and then made my first piezography print of the image at the top of this post. It came out kinda flat and with some funny coloring to the image. Well I had made the first of many mistakes in learning about printing with these new inks. The first mistake I made was trying to save a little bit of ink and time by printing at 1440 dpi. Normally with the Epson Ultrachrome inks there is not too much difference between 1440 and 2880 dpi. Not so with these inks on the 1400, according to Jon Cone the printing curve description files were made specifically with the 2880 dpi resolution as the intended target.

My next print was done at 2880 and came out looking tons better! There was a decent amount of black in the image now, and the mid tone contrast was dramatically improved, along with highlight separation. Also at this point I could see that there was a very interesting color shift in the upper mids to highs around the sun and gradually radiating through the left third of the image. I thought that this was an amazing split with warmth in the mid to upper regions and gradually going through a neutral/cooling descent into black. This wasn’t really how the inks were supposed to perform. What I was seeing was just a very lucky coincidence of the remaining yellow ink that was still in the printer, and seemed to really only show up in the areas that looked incredibly interesting around the lighter areas of the photo. That first night I probably printed at least 8 different versions of this image on several different papers and was amazed about how much the colors changed as I chaged each paper. While Piezography normally does go through subtle hue changes with different papers, that was not was not what I was seeing. I was still seeing the final remnants of the color inks that were originally in the printer.

To be continued….

Slow going, but keeping at it

Yesterday I finished print number two, which was a long time in coming. I actually made what I thought was the final version of print number two about a week ago. But after letting it sit out to dry for a day I looked at the image closely before I boxed it up. On close inspection I could see some digital artifacts in some of the rock detail that just weren’t visible to me in the smaller prints. These image flaws made some of the very abstract detail in the rocks look harsh and brittle (very digital-ly looking, now there’s a word for you). I didn’t like this at all and felt that this was something that I wouldn’t really be happy giving to someone else, so I went back to the computer to see what went wrong.

It turns out that the problem was twofold. While working on the image in Photoshop I tend to go no larger than 50% magnification (unless something requires very small scale editing). I had applied at least 2 rounds of sharpening to the image as I worked on it. This alone wasn’t a problem, as the image looked fine as 6×10″ and I’m pretty sure it still would have been fine up to 11×17″. The images for this portfolio are being scaled up to 14×21″ and on top of that the scaling algorithm that I was using does another final round of output sharpening as part of this enlargement process. It was this final round of sharpening after scaling the image up that did this print in.

Digitally enlarging an image is a pretty interesting process that can be done in any number of ways. Choosing the best way to scale an image has become a good deal easier in recent years. Back in the “old days” pre 2004 we used either Photoshop’s bicubic method or spent some money and purchased a program like Genuine Fractals (GF), which was a very popular program for doing these kinds of things. Before Photoshop CS/CS2, Genuine Fractals was noticeably better than Photoshop’s bicubic method. PS CS3’s bicubic smoother and sharper scaling algorithms are much better nowadays especially for things that are likely only going to be scaled from a 10+ megapixel camera up to a 17×22″ print size. There are also tools like AlienSkin Blow Up, and Qimage. A couple of years ago I looked closely at all of these products (and several techniques for scaling using Photoshop tools) and was never really able to produce demonstrably better enlargements (of my images, to my desired size) with these other programs than I could with what was already in Photoshop. So I just stuck with Photoshop’s bicubic smoother, or the upsizing routine from the folks at Digital Outback Photo.

I think that in my case, I just didn’t have a need to up rez my photos to the point that these more expensive (and hopefully more advanced) scaling algorithms had a chance to show their stuff. In this particular instance it was the Digital Outback Photo upsizing method that caused print number two to be botched. I’m pretty sure that had it not applied that final bit of sharpening the image would have looked ok. With that discovery I resized the image simply using Photoshop’s bicubic smoother and it looked fine, no longer harsh and brittle. I also decided that I’d take another look at Qimage now that I had an image that was actually kinda difficult to scale to the size that I wanted.

Qimage is a program that has a very avid following out there in the inkjet printer community. Qimage not only provides several advanced scaling algorithms, but also employs its own “intelligent” form of output sharpening, and also a page layout facility (which automates the most efficient placement of multiple images on a single page). Oh I forgot to mention that Qimage is also a fully color managed image viewer and print spooler too! Over the years I’ve wondered what it is about this program that causes so many of its users to scream its virtues at the top of their lungs, where I couldn’t see any real improvement over the scaling that I performed in Photoshop.

Its getting late and I’m pretty tired, so I’ll have to continue this post tomorrow…zzzz

New Epson 1400 Printer

I’ve been out of town for the past few days camping near Lake Cachuma with the family and my son’s scout troop. But just before I left my computer gremlins left another present for me. My new hard drive to replace the failed mirror drive started reporting errors on Thursday night. Of course this angered me to no end. So my time on Thursday was spent trying to figure out what was wrong, or if I just have bad luck (more on the luck thing later). I was all set to just rip the drive out and wait for a replacement from Western Digital (this is an RE2 drive which is supposed to be very reliable). When I thought that maybe there could be a hardware problem in my drive subsystem. So I ran SpinRite 6 on this drive all night long in mode 4 which is the deep cleaning and analysis mode. In the morning it reported that there were no errors on the drive.

When we returned from the camping trip yesterday I was pretty perplexed about what to do about the drive system. For the time being I’ve just replaced the SATA cable, and re-added it to the mirror. The drive has been functioning properly yesterday and today with no errors. I’m keeping my fingers crossed, but if the system once again starts logging errors on that drive while SpinRite claims that it is ok, I may have to look into getting a standalone RAID controller (which would totally suck).

Today when I got home my Epson 1400 printer had arrived. I had ordered one that was supposedly a “like new” printer that just was in an open box. Well that was being a bit generous. The printer has obviously been used, didn’t arrive in its original Epson box, was missing the install CD, and one CD printing accessory. I suspect that this may have been a floor model at the store I bought it from since there are signs of use in the form of light scratches on the cover and buttons. To make matters worse the printer didn’t work when I took it out of the box. It reported that the black ink cartridge was empty (even though the cartridge was new and in a sealed wrapper). After talking with Epson they said that the only way to tell if the problem was in the printer or a defective cartridge, was to put in a new cartridge. They shipped me one for free but it won’t get here ’till Friday. I couldn’t wait that long to find out if the printer really has a problem so I went to Frys Electronics and bought a replacement cart. Luckily the printer immediately fired up with the new cartridge, so maybe I just had a mid sized amount of bad luck going for me today. Luckily Epson does a pretty darned good job of standing by the warranty on their printers and is always ready to ship a replacement part (or whole printer if necessary) when something goes wrong.

With all the disk/printer problems in the past few days I haven’t done any work on my portfolio. I just wonder why the hardware problems are around every corner of my life when I’m trying to work on this portfolio, its like the gods are frowning on me for even attempting to do this…

Back in business!

When I got home from work today, a package from Zalman was here with a replacement fan for my CPU Cooler. I got it installed in about 10 min, and then installed the replacement hard drive for the one that failed. I’m typing up this blog entry from my main machine, while the RAID system is rebuilding the mirror (duplicating all files on to the new disk). With things going fairly smoothly with all the new hardware installed and running I’m feeling in a much better mood now.

I might not be able to get back to working on my QTR ink curves for the portfolio tonight, but at least I should be able to dig up some photos and start including them in the previous blog entries.

While the computer works on fixing itself I probably will need to spend some more time on configuring new plugins for WordPress, and working with my hosting provider to sort out some linking issues on the web site.
