Photographing in Manual Mode to create Beautiful Exposures

©Judy Host 2014 | Lens: 70-200mm F2.8 EX DG OS HSM | Aperture: F 7.1 | Shutter speed: 1/320sec | ISO 320 | Focal length 80mm| Exposure: manual mode | Processed in Photoshop using Perfectly Clear by Authentic to add a bright and more saturated look.

Learning to use manual settings in your camera will provide you with the ability to create the beautiful exposures you desire. The exposure in your camera is determined by several different settings. Exposure refers to the lightness or darkness of the image. The settings are: 1) the aperture, the lens opening, which lets in light and controls the depth of field; 2) the shutter speed, the speed by which the lens lets in light, and 3) the ISO, which controls the camera’s sensitivity to light. The right combination of these three settings will give you a nearly perfect exposure and give you the effect you want for your image.

High Concept Photography

In “The High Concept Image,” a recent feature in Outdoor Photographer, nature photographer Ian Plant intelligently challenges photographers to capture creative, thoughtful images that move beyond “snapshots,” rising to the level of “art.”

Ian’s description of the high concept image is in contradistinction to the “low-concept image,” which he points out is generally more “documentary” or “literal” in nature. Seeing nothing wrong with such grab shots, he does, however, push photographers to look for new ways to depict the world. He invokes legendary photographer Minor White, who once said “One should photograph objects not only for what the are but for what else they are.”

The Challenges of Photographing in Natural Light

© Judy Host 2013 | Lens: APO 70-200mm F2.8mm EX DG OS HSM | Aperture: F 7.1 | Shutter speed: 1/200sec |  ISO 800 | Exposure mode: Manual mode | Focal length: 157mm

The challenges of photographing in natural light can be many. I don’t always get to choose when I photograph, especially because I photograph children and sometimes the best time for them is in the middle of the day. When that happens there are a few things that can help to make this actually work pretty well.

What is a Zoom Lens? And why and when to choose a Zoom Lens?

Sigma offers a great variety of zoom lenses. (Lenses are not shown to scale in this display.)

A zoom lens is a type of camera lens that is offers the photographer a useful range of different focal lengths in a single lens. This is in comparison to a prime lens, which only offers a single focal length. A zoom lens allows for quick and easy re-framing of a scene while staying in the same physical position. Sigma offers a line of over 20 zoom lenses for DSLR photographers, ranging from wide angle zoom lenses, supertelephoto zoom lenses, and high-zoom ratio all-in-one lenses for both full-frame (DG) and APS-C (DC) digital cameras.

All-in-One Wedding Solution: Sigma 24-105mm F4

This month I was invited by Sigma to test out their brand new Sigma 24-105mm F4 lens and to shoot a series of bridal images to demonstrate the versatility of the lens. I decided to put together a fashion-influenced bridal shoot in a stunning location and with the help of my incredible talented creative team. Once I had put together striking visual elements, I would then test all features of the lens that would be important to me as a working photographer.

For several years I photographed weddings, and all the challenges that come with them. I realized very quickly that the last thing I wanted to worry about was my gear. I had to focus on the posing, the lighting, keeping everyone happy, my extremely long shot-list, and much more. I needed to know my gear was reliable and would help me get those must-have moments. When I started I didn’t have a second shooter or assistant; I was the one-woman band expected to make every shot count.

Photograph Anyone’s Good Side: Part 2

© 2013 Lindsay Adler

When your job is to flatter your portrait subjects, you need as many tools in your photographic toolbox as possible so you are prepared for any features, and any ‘flaws’.

I think it is important to mention that I am not judging people’s appearance. As a fashion photographer, I often get to photograph what society considers “ideal” forms of beauty. What I notice time and time again, however, is that certain models’ “flaws” are what make them unique and memorable. In fact, there are several supermodels with so-called flaws like gapped-teeth, unusual noses, and more.

What matters is not what society says is ‘perfect’ but instead how your subjects perceives themselves. You want them to feel confident, attractive and proud of the images you provide them. You want to help them reduce anything they are self-conscious about and help their expression glow in their images.

Sigma 18-35mm F1.8 DC HSM | Art: First Impressions

The world's first constant aperture F1.8 zoom lens.

We’ve just announced the world’s first F1.8 constant aperture zoom lens, the Sigma 18-35mm F1.8 DC HSM | Art lens, and I’ll readily admit, we on the Sigma Corporation of America team have been just as excited about this lens leading up to launch as photographers have been since it was officially announced in the wee hours of April 18th. And now that I’ve spent some time with my hands on a preproduction version of the lens paired with my Sigma SD1, I, truly cannot wait ’til this lens starts shipping and I can share high-resolution end result photos! Today we’re going to focus on what we can talk about–the hand feel, build quality, and such of this brand new lens designed specifically for APS-C DSLRs.
