Perfect Portrait Camera: DP3 Merrill

The quality medium format cameras no matter what the brand stand out as superior to most DSLR cameras. This is particularly true when super large prints—thirty by forty inches and large—are to be made. Color fidelity in medium format is…

Macro Flash Photography: Create Natural Looking Macro Images

One of the most important rules for macro flash photography is balance. For natural looking macro images you have to balance the ambient light and flash output. When the flash and ambient light are balanced the use of flash will not even be apparent to the viewer.

The problem is that with flash output overpowering the natural light in background it will underexpose and go dark, in some cases like the image below, it can underexpose to the point that is appears black.

Prime Lenses for Mirrorless Interchangeable cameras

A year ago I purchased a 24 megapixel Sony NEX-7 to use as a backup camera during a trip to Belgium, Germany and France. I carried Sigma’s 19mm and 30mm f/2.8 prime lenses. The quality of the photographs amazed me every evening when I downloaded the day’s take. Those results made me carry my “big boy” Canon 5D Mark 2 less than I’d originally planned. The professional quality coupled with it’s touristy—amateur look, I was never questioned in museums, cathedrals, gardens or when I was doing street shooting.

How to Control Extremely High Contrast Scenes

Photographing in the field in contrasty harsh light is something every photographer has to deal with. This is a technique that I use for those difficult high contrast situations. For a more natural looking image you need to take control of the light to handle the light and dark tones in a high contrast image.

It is important to understand the problem with high contrast scenes. Exposing for the light tones will cause the darker tones to underexpose and exposing for the darks will result in blown out highlights.

Secrets to Success with the Sigma 50-500mm F4.5-6.3 APO DG OS HSM

The Sigma 50-500mm F4.5-6.3 APO DG OS HSM is one of my favorite lenses of all time. My copy has been there by my side shooting in rain, snow, freezing low temps, scorching high temps and more delivering the sharp images I need month after month.

Exercise your Creativity with Prime Lenses

More and more I find my self shooting one of three Sigma prime focal length lenses in the studio… the 50mm f/1.4, the 85mm f/1.4 and the 150mm f/2.8 OS macro. I noticed that zooms were making me a bit lazy. Hey! It’s a lot easier to twist a zoom ring that it is to move a 300 pound studio stand even if it is on wheels. So why do I do it? A couple of reasons. Perspective, perspective, perspective. I shoot full frame Canon cameras. Their normal focal length is almost 50mm. That’s about the same angle of view as we see with our eyes. I use the 50 mainly for full length photographs.

Macro Photography: How Sensor Format Affects Image Depth of Field

One of the biggest challenges with macro photography is working with a limited depth of field or DOF. When I am shooting macro I am always trying to make sure the subject and elements in the frame appear sharp by adjusting the aperture and making sure the important elements in image fall on the plane of focus by adjusting my angle of view. But there is another important element that has a huge effect on DOF that most people don’t even know about, how a different sensor format can and will effect the depth of field in your image. Moving to a smaller sensor format at the same apparent magnification will give you lots more DOF to work with in your macro images.
