HDR Photography + Focus Stacking

In my workshops and presentations over the past few years, I have discussed my extensive use of two powerful software packages: Helicon Focus and Photomatix. Helicon Focus stacks multiple images, each focused on different planes, creating one super-focused image. Photomatix combines multiple images photographed with different exposure values, creating one file with a super-wide exposure range.

In conjunction with Sigma and Hunt’s Photo, I recently lead a garden photography workshop at The Botanic Garden of Smith College in Northampton, MA. There and anywhere I lead a workshop dealing with macro photography, I always stress the importance of choosing your f-stops wisely.

The Magic of Iceland

© 2013 Roman Kurywczak | For the foreground: Sigma 12-24mm | Focal Length: 12 mm | ISO: 100 | Aperture:  f/22 | Shutter speed: 1/3 sec. For the sky: Sigma 12-24mm | Focal Length: 12mm | ISO: 100 | Aperture: f/22 | Shutter speed: 1/5 sec.

Iceland has long been on my list of photography destinations so I was very excited to finally get a chance to explore the country as well as try out the Sigma 12-24mm. The landscapes were just breathtaking and I got an opportunity to photograph the many waterfalls of the country. The lens quickly proved itself as I was able to compose and recompose quickly given that I was often very close to the falls! One of my favorites is a triple waterfall near Mt. Kirkjufell (shown above). While I normally use split neutral density filters to balance a scene, I decided instead to blend two exposures (one for the sky and one for the foreground) because of the mountain protruding on the right hand side. A split ND filter would have unnaturally darkened Mt. Kirkjufell so an exposure blend was the best option in this case.

Experimenting with Polarizer Filters

A polarizer filter helped bring out the blue sky in this shot taken during the Sigma FitzSimmons Photography Island Adventure photo workshop on Kelleys Island, Ohio. By turning my polarizer, I was able to bring out the blue skies over Lake Erie. Sigma SD1 Merrill. Sigma 10-20mm F4-5.6 EX DC HSM lens set at 18mm. f/11, 1/15 sec. ISO 100. Sigma 77mm Circular DG Polarizer Filter. Gitzo GT2451EX tripod with Gitzo ball head. Processed in Sigma Photo Pro 5.5, optimized in Adobe Photoshop CS5, NIK Viveza plug-in applied.

It’s pretty well known that a polarizer filter may deepen the color of blue skies, but the more subtle effects of a polarizer are often less known–and certainly worth exploring.

Polarizers limit the light that penetrates through them. As such, they help reduce contrast. Polarizers are like prison bars, where the light bouncing up and down through the bars passes through, but the light waves traveling horizontally do not. Of course, polarizing filters can be rotated, changing which directional light reaches a camera’s sensor and which does no

Sigma 15mm F2.8 EX DG Diagonal Fisheye lens

I have always wanted a fisheye lens and have always talked myself out of the purchase, confident that it would gather dust when the novelty wore off. Recently, after becoming interested in wide-angle macro photography, I bit the bullet and got the Sigma 15mm F2.8 EX DG Diagonal Fisheye. It’s now been two months and I honestly can’t put the lens down. A few weeks ago, my dad commented that my worldview is becoming warped and I hope he was just referring to the pleasing distortion in all my recent images.

Nature Photography with the Sigma SD1 Merrill

© 2013 Alex Filatov | Camera: SD1 Merrill | 24-70mm F2.8 EX DG HSM | Shutter speed: 1/25 sec | Focal length: 24mm | Aperture: f16 | ISO: 100

When Sigma offered me the chance to shoot with the flagship SD1 Merrill DSLR, I jumped on the opportunity to extensively explore the abilities of the Foveon X3 censor at the heart of the camera. Knowing that my plans involved photographing the natural beauty of the mountainous American West allowed for the selection of several lenses from Sigma’s fine catalog most suited for that purpose – the 8-16mm F4.5-5.6 DC HSM wide angle, the 24-70mm F2.8 IF EX DG HSM mid range zoom and the 120-300mm F2.8 EX DG OS APO HSM telephoto.

Wildlife Photography with the 120-300mm F2.8 EX DG OS HSM

© 2013 Roman Kurywczak |

I have been looking for an intermediate telephoto zoom lens to add to my lens arsenal. I have owned the Canon 100-400mm lens for a while now but I have never been happy with its sharpness or overall performance and the push pull mechanism for zooming was not very smooth and made tracking while zooming difficult. I was looking at 70-200mm f/2.8 lenses but I felt that I wanted a bit more reach for an intermediate telephoto zoom lens. Someone suggested that I try out the Sigma 120-300 f/2.8 and it looked to be a great idea as it fit nicely in my lens lineup between my wide angle lenses that ranged up to 128mm and my super telephoto Sigma 300-800mm f/5.6 lens.

Eight years ago, the North American Nature Photography Association (NANPA) designated June 15th as Nature Photography Day. This year, it will be observed on Saturday, June 15th. This day was created by NANPA to promote the enjoyment of nature photography, and to explain how images have been used to advance the cause of conservation and protect plants, wildlife, and landscapes locally and worldwide.

For the love of photography | By Gabby Salazar

© 2013 Gabby Salazar | A woman sits on a stoop in the streets of Cusco, Peru. Sigma DP2s.

My father started taking pictures when he was in the army. He rediscovered his love of photography when I was around 11 years old, and he gave me my first camera as a gift and sat me down in a friend’s backyard bird garden with a Sigma 170-500mm. The first time I looked through that lens I was hooked on photography. A blue jay alighted on the stick that the camera was focused on and I snapped the shutter at my father’s urging. When we got home, my father enlarged that image and printed it for me. The image was tack sharp, the colors vibrant and the blue jay looked alive!
