The Changing Landscape Of Printing


The digital print gives photographers more freedom and control in getting great images.


Wings of Spring

Printing possibilities offer so much for landscape photographers today. Digital photography along with inkjet prints give greater freedom for the photographer to truly capture what he or she saw.

For landscape photographers, the print has gone beyond a simple record that goes on the wall. With printing so accessible to all, photographers have the opportunity to create dramatic, large-format prints that demand attention.

As an outdoor photographer, I can honestly say that the advent of digital photography and printing technology now allows me greater freedom, both in the field and in the studio. Moreover, after the hard work in the field, there are few things as rewarding as seeing a beautiful print roll off the printer, taking you back to that special moment.

Much of my older work was done in large format, though for the past few years my images have been predominantly captured with D-SLRs. This latter fact often is greeted with surprise, especially at the sight of some larger prints. As a large-format photographer, I was as skeptical as anyone about the enlargement potential of digital capture—until I tried it myself. Depending on the print process, image resolution numbers in the 200 to 400 dpi range are generally required to produce a sharp print. To put this in context, in order to make an 8x10 print at 200 dpi, your file will need to be sized to 1600 x 2000 pixels (3.2 megapixels). This is still far below the native resolution of most modern digital cameras.

When you make your own prints, you gain control over every aspect of the image, allowing you to customize the results to your taste and style. Such control is all the more meaningful considering the ever-growing array of choices— from printers and inks to color management tools and digital imaging applications, all the way to the large variety of papers, each with its own unique look.

Previsualization
I like to approach the processing and printing of my work with the same mindset as I do capturing images in the field. I seek to create something that’s unique and expressive, something that communicates the sense of awe and discovery that I experienced myself when in the presence of great natural beauty.

My prints are visualized outdoors, on the trail, in the depths of canyons or on the slopes of mountains. As I frame and compose my images, I also consider how they might look on paper. The process involves more than just an appealing composition, but also examining areas of detail that may require attention.

When back at my studio, my imaging workstation is my light table, my development and processing darkroom, and my print lab all rolled into one. As I pull up newly made images, memories of each moment come alive. The ability to review multiple compositions side-by-side is invaluable in the process of editing and selecting which images to print. The digital process allows me to push the envelope and choose the one frame that’s just different enough to make it that much better than other similar ones.

Ink And Paper
Just as there’s no one right way to photograph a given subject, there’s no one right way to print a given image. Famed photographer Ernst Haas noted that "the best pictures differentiate themselves by nuances," and the power of digital printing puts complete control of such nuances in your hands. While some images benefit from deep saturated blacks, others may rely on subtle pastels or high-key whites; others still may benefit from the glare-free surface of cotton rag papers or the luscious, saturated gloss finish of coated ones. The choices abound and readily plug into your workflow.

Inkjet printers fall into two main categories: those using pigment-based inks and those using dye-based inks. Pigment inks are more stable and archival since they’re more resistant to UV light, but they‚’re more expensive to produce. Dye inks have a broader color gamut, though generally aren’t as stable and will fade sooner when exposed to UV light. Modern inks, both pigment and dye, have come a long way toward improving both archival and color qualities.

When it comes to paper, the wide field of options falls into two main categories: coated papers (e.g., resin-coated, or RC), which offer more traditional glossy or textured surfaces, and fine-art papers (e.g., cotton rag), which have a matte surface and produce prints looking like something between a photograph and a highly detailed watercolor painting. Remember that dye inks, while having more favorable color gamut, look best on coated papers and generally aren’t suitable for fine-art papers. Pigment inks work very well on both types of paper, however.

Color Calibration
How can a printer know what red looks like on your monitor so it can reproduce it accurately? The solution is color calibration or profiling. A color profile maps colors to a device-specific way of producing those same colors, such as a printer.

Monitors are generally profiled (or calibrated) using a color-measuring device called a colorimeter. These are available from vendors like Datacolor, Pantone and others. Printer profiles are specific to each paper and ink combination. Most printer manufacturers provide a set of ICC profiles with their printers, and the same is true for many independent paper manufacturers.

Keep in mind that having a color-managed workflow and ICC profiles for your monitor and printer ensure consistency, but rarely result in a 100% match. Differences result from the fact that transmissive media (e.g., your screen) and reflective media (e.g., paper) have some inherent characteristics that can’t be fully overcome with profiles. Experimentation is needed for best results.
