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.”

Macro Flash Photography: Create Natural Looking Macro Images

©2013 Robert O'Toole | Exposure mode: Manual mode | Shutter speed: 1/200th sec | Aperture: f8 | ISO 200 |  flash @ 1/40 output level | Lens: Sigma 105mm f/2.8 OS macro lens

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.

A macro lens isn’t just for nature photographers capturing the intricate beauty of a flower or the amazing detail of an insect. Furthermore, it isn’t just for product photographers photographing the detail of a delicious meal or details of a ring.

A macro lens is an incredible tool for any beauty photographer to have in their kit.

Macro Photography: How Sensor Format Affects Image Depth of Field

© 2013 Robert OToole Photography | Lens: Sigma Macro 150mm F2.8 EX DG OS HSM |  Camera: NIKON D800E | ISO: 100 | Aperture: f8 | Shutter speed: 1/250 sec | single SB-R200 flash. This flower was framed in the viewfinder with a full frame sensor format body in FX (full frame) mode.

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.

Macro-licious and more…

© 2013 Kevin Ames

Macro lenses are for making pictures of bugs, watch parts, coins, jewelry and other tiny stuff. Right? Well not necessarily. Recently one of my model buddies wanted some beauty photographs that mimic Cover Girl makeup ads. We gathered one Friday morning at my studio and went to work. I set up an evenly lit white background using V-Flats while Hope had her makeup done by Kristen White.

Macro Photography: Working Distances with the Macro 105mm F2.8, 150mm F2.8 and 180mm F2.8

Judging by the number of questions I get from photographers concerning the working distances of macro lenses I think it is a good subject to talk about.

The working distance of a macro lens, not to be confused with minimum focus distance, is the distance between the front of your lens and the subject. This is different from the minimum focus distance which instead means the distance to the subject as measured from the focal plane mark on the camera body, not from the front of the lens. Working distance is a more important figure since it tells how much space you have between the front of your lens and your subject. Working distance generally increases with longer focal length lenses, shorter lenses usually have shorter working distances.
