Tuesday, March 2, 2010 Watch Out For Blowout
Exposures In All The Bright Places • Traveling With Photo Gear • Fine-Art Prints, Or Not  In the days of film, exposure in bright areas was always a challenge, and we’d constantly try to outthink the meter by over- or underexposing our images. |
Tuesday, January 26, 2010 Trying Infrared
Infrared, Inside Out • From CRT To LCD, And Even LED • 2X Or Not 2X • Separate The Pros From The Cons  What are the advantages, if any, of having a digital camera converted solely to infrared capture versus using the B+W 093 IR filter on my DSLR? |
Tuesday, December 1, 2009 Tame Your Dynamic Range
HDR au naturel • Hybrid Lenses • Pros And Point-And-Shoots  A neutral-density filter is used to darken an image to allow increased exposure time. |
Friday, October 30, 2009 Beware Of The Sun?
A Burning Question • What’s A Pro Camera? • Prints From The Dark Side • When Things Get Wet  I recently “went digital” with a Nikon D90. While exploring the user’s manual, I was surprised to read a warning to keep the sun well out of the frame when shooting backlit subjects. |
Tuesday, October 6, 2009 Shooting Under Paradise
Getting Wet • HDR On Moving Subjects • JPEG Sources • Viewing Video On Your LCD  During a recent foray to Hawai’i to give seminars and workshops for the Canon Explorers of Light, I knew I’d be doing some snorkeling. (Hey! Somebody has to do this job!) I’ve previously used PowerShot compact digital cameras with underwater housings. |
Tuesday, September 1, 2009 Do I Need Permission?
Commercial Vs. Editorial Uses • Sharp To The Edges • Extended Macro • TILT!  In the August 2009 issue of Outdoor Photographer, you discussed the difference between commercial and editorial uses of images and the need for releases. Please expand on the definition of editorial uses. Would I need a signed permission from the owners of the properties I photograph to use the images in a book? |
Tuesday, August 4, 2009 When It Goes Wrong
Hit By Lightning • Hydrate! • Bad Rocky Mountain High • Sooooo Cold • Lost Going To The Devils Postpile• Bugs In The Amazon • All Images Lost  Anytime you get a group of professional photographers into close proximity, you’ll find them gathered ’round the campfire (or in the local pub) to swap stories and talk shop. |
Tuesday, July 7, 2009 The Perfect Solar Storm
Chasing The Aurora • The Full-Frame Advantage • The Silent Click • Please, Release Me  I saw your photograph of the looping aurora borealis as one of the wallpapers within Microsoft Vista OS. Where did you take that photograph, and what’s the best time of year to try to capture the aurora?

Tuesday, June 9, 2009 Taming The Skies
Bringing The Sky Down To Earth • Real Real-Estate Images • Extended Autofocus • Film Everywhere, But No Place To Process • Gauging Filter Effects  My true love is landscape photography and, in particular, I love sunset landscapes. One of the big problems I have in post production is optimizing both the sky and the land (and, sometimes, water). |
