The Truth Is In The Details • Make It A Hard Drive • Times Two • When To Use IS • Airports And Cameras • Res It Up I’m using a high-resolution digital camera and just started photographing trees, bark, leaves, etc. Many of my photos don’t show good resolution in the small details, such as bark texture, the small veins in leaves or the edges of paint peels. I shot images today using a tripod, mirror lock and cable release, and I used an f/11 aperture on a 100mm f/2.8 macro lens. The image looks soft in several places. Is what I’m seeing a problem with digital capture?

Keeping It Simple
Sticking With Film • Simpler Digital • Accessories • Simpler Image Handling • Beyond Simple Yes, the world is a complex place. Technology can be baffling. True, some people just seem to be dedicated to making things difficult, and I know, sometimes you’ve read this column and thought photography was getting to be too technical and full of "stuff." But what’s important is the end result: an image that communicates or motivates. There are many ways for you to achieve your photographic vision and it doesn’t have to be that hard.

When And How To Sharpen Most professionals recommend sharpening a digital image before printing. I like a sharp image and use either a tripod or flash to improve the capture results. I feel using sharpening prior to printing makes the final print, in some cases, look unnatural. Why do the professionals use sharpening, and should I be using it?

Showing It Right I’m giving a program to a large camera club next month. What information do I need to give them in preparation for my showing my images? I want it to come off looking professional, but I’ve never done this before.

Closer And Bigger
I’m using a Nikon D70 with 60mm and 105mm Micro-Nikkor lenses for wildflower photography. Lately, I’ve become interested in lichen photography, which sometimes requires magnification up to 2X or 3X life-size. I don’t believe that extension tubes will work with the digital camera. Do I need to go back to my film cameras? Or is the alternative to use the Canon system with a Digital Rebel and the MP-E65/2.8 1X to 5X macro lens?

I have many film images on 35mm and even more on 6x7cm film. I could never afford to get very many drum-scanned and printed. I want all the detail I’m used to seeing in prints from 6x7 images. That’s why I moved to 6x7 in the first place. I note that Epson has a flatbed, V750-M PRO, that William Neill now uses, and Nikon has the 9000 ED desktop scanner for medium-format film that you’ve used. I’m looking to print my 6x7 images at 16x20 or 20x24. Will either of these scanners serve my needs?

The Saturated Digital Image
Color Saturation In Digital Images • Pro Time • Long Lens Protection • Digital Projection As a professional photographer who’s making the switch from film to digital, I wonder how other pros are dealing with color saturation. On many photographers’ websites, the photos and portfolios look to me to be oversaturated, which makes me wonder about claims that Velvia is unrealistic because it’s so saturated. What’s a "fair" level of saturation in the digital world, and is there any standard in the publishing industry?

Digital Basics For Outdoor Photography
Image Capture • Optimize • LCD Viewing • Share In this column, I'll address questions concerning critical digital photographic equipment and skills. These are the kinds of questions often asked by students at my workshops and seminars, especially by photographers still considering whether they want to change from film to digital or those just making that change. But even advanced digital photographers find they lack essential equipment–in the camera bag or at the desktop–and the knowledge keeping them from achieving their photographic vision in the digital realm.

I’ve heard conflicting recommendations on where to set the white balance on my digital camera. Some sources advise the use of automatic white balance; others say to use a different white-balance setting for each specific light source. What do you think?
