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?

Medium-Format Scans

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.

White Balance

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?

Big Suns

I’ve always enjoyed dramatic landscapes featuring a big sun. What kind of lens should I use to achieve this effect?

Infrared Photography

IR Possibilities • Flying With Photo Gear • LCD Viewing • Image Compatibility • Brightness/Contrast Methodology • Sensors & Wide-Angles

I have a Fuji FinePix S20 Pro, which I read a few months ago is supposedly capable of making infrared digitals. Any idea how I would do that?

Photographers In Harm's Way

How Far To Go For The Ultimate Photograph? • Reciprocity Compared • Digital Black-And-White • Snowy Details

There seems to be no end to the dangerous things photographers will do to get the ultimate photograph. Each of us has to decide how far to push the limits, but collectively, we're all influenced by other photographers' failed attempts. I'm increasingly concerned by the imposition of more rules and restrictions to our access in both public and private locations due to the government's or the private owner's perceived need to protect themselves from liability and to protect ourselves from our own recklessness.
