Beware Of The Sun?

Prints From The Dark Side
Q I shoot in Camera Raw and process images in Adobe Photoshop Lightroom 2 with great results. I have a laptop with a high-definition monitor that I calibrate, and the images look great on my computer when I’m finished processing. However, when I send these images to my Epson R2880 printer, they print very underexposed (color seems okay, but exposure is very dark), and I have to greatly overexpose the image in Lightroom to get a properly exposed print. Is there a way to adjust my Lightroom processing or print process so that what I see in Lightroom is what I get in a final print?

A You don’t mention whether your printing process includes printer (paper) profiles. These convey a set of instructions to the particular printer you’re using about how to properly lay the ink down on the selected media. Watercolor papers, for example, are much more absorbent and will print the ink in different color and dot sizes as compared to glossy paper, where the ink stands on the surface and maintains a very small dot. Epson furnishes printer/paper profiles for their printers and papers. Photographic paper manufacturers, such as Moab, also offer printer/paper-specific profiles. I can’t overstate the importance of the combination of a consistent, calibrated monitor and appropriate printer/paper profiles for successful print production. With this preparation, I have on numerous occasions produced a perfect print on the first try with both Canon and Epson professional printers, right out of the box.

On my Canon imagePROGRAF professional printers, I modify the printer/paper profile if I feel it isn’t producing the color, saturation, tonality, contrast or brightness I seek. Rather than making these changes in Lightroom on my image file, I can modify the output parameters to make fine adjustments, and I can save these modifications in a custom profile to be used again later.

When Things Get Wet
Over the years, one of us (guess which one) has dunked a lot of expensive camera equipment in wet places. We’ve recently come across a possible quick solution. The Bheestie Bag is a sealable bag with a pouch of powerful built-in desiccant included (www.bheestie.com). The bag is a bit small as it’s designed for electronics like compact cameras, cell phones (just another camera) and iPods, but the packet of desiccant can be placed in a larger sealable bag if the lens or camera body is larger. The Bheestie Bags weigh almost nothing and take up very little space. I’m carrying two of them, just in case. By the way, a bheestie, in India, is a water carrier.
