Sharpness – Relative vs Absolute

by 9 Comments

ManzanitaThe more I photograph nature, the less I’ve been concerned about sharpness. It’s not out of laziness, but from the realization that relative sharpness is much more important than absolute sharpness.

Absolute sharpness is about making your subject as sharp as possible, within the limits of your camera and lens.

On the other hand, relative sharpness is about making your subject as sharp as possible relative to other elements in that image.

This also applies to depth of field, and in this article when I mention sharpness I also mean depth of field/focus.

For example, here’s a photo with a lot of absolute sharpness: [Read more…] about Sharpness – Relative vs Absolute

Pressing The Button

by 8 Comments

Pressing the ButtonPressing the shutter button to snap a photo seems like the most simple part of photography. I mean, you just “press the button” — right?

Well, there’s a few things to remember when pressing that button, especially when you’re handholding the camera:

1 — Press the button halfway first

You’ve probably noticed that you can press the shutter button halfway or all the way down. When you first got your camera, pressing it halfway probably initiated autofocus (but, hopefully now you use back-button autofocus).

With back-button AF (and if you’re in manual mode), pressing the button halfway does nothing to camera settings, but physically it’s important. Pressing the button all the way down in one press puts much more physical pressure on the camera than doing it halfway first, stopping for half a second and then going down the rest of the way. Physical pressure is important because with more pressure, you’re shaking the camera more and that increases your chance of getting a blurry photo and can mess up your focus point and/or composition (especially true for close-up images).

Composition is more difficult for microphotography than for other types of nature photography.

Your subject might be an insect or a spider sitting on a difficult-to-reach place. Add the fact that you need to approach very carefully to not disturb your subject and you have a bit of a tricky situation. There are no golden rules to help you solve this one. Play around with composition until you get something that works.

In microphotography, you want to simplify your image as much as you possibly can. Fill up as much of your frame as possible with the subject. Have your focus as sharp as possible and don’t be afraid to experiment with different angles to find the one with the most aesthetic appeal. Photos at high magnification have a corresponding shallow depth of field, so precise control over the location of focus is critical. This requires not only artistic decisions about what part of the subject should be tack sharp, but also technical decisions about how to make the most of this sharpness.

One of the most popular books that I read during my childhood was Eric in the Land of the Insects, written by the Dutch author Godfried Bomans. In this humorous fantasy, nine-year-old Eric enters the landscape painting that hangs on his wall and he discovers a world of man-sized wasps, bees, butterflies and other insects that is stunningly similar to the world of humans. Once photography became a part of my life and I purchased the Canon extreme macro lens MP-E 65 mm f/2.8, which has combined with a 2x teleconverter a maximum magnification of 10:1, my world was populated with grasshoppers, spiders, snails, flies, dragonflies and butterflies—Eric’s world.

Magnification describes the relationship between the actual size of the subject and the size of its image on the sensor of the camera. Photographing a 3 cm (1.18 inch) long blue-tailed damselfly so that its image size is 1 cm (0.39 inch) on the sensor means that the magnification is 1/3 (1:3) life-size. Dividing the size of the subject’s image on the sensor by the actual size determines the magnification. At 1:1 life-size, the size of the subject on the sensor is as big as it is in real life. Macrophotography is restricted to magnifications in the order of 1:10 to 1:1 life-size. Microphotography is the extreme form of macrophotography, dedicated to the photography of small objects from life-size to modest enlargements of up to about 20.

How To Focus Closer With your Lenses

by 3 Comments

Every lens has a minimum focusing distance: the closest point where the lens can get a sharp focus. Generally, the longer the focal length of the lens, the greater the minimum focusing distance.

Most of the time, this distance isn’t a problem because with longer lenses you’ll generally be photographing a distant subject.

But, those longer telephoto lenses are also great for close-up photography, because they help you isolate your subject against a specific part of the background. In these cases, this minimum focus distance often becomes a problem because many lenses won’t let you get close enough to fill the frame with a small subject (such as a wildflower or insect).

So, how do you make your lens focus closer? [Read more…] about How To Focus Closer With your Lenses

Three Reasons to Photograph Wildlife at Eye Level

When you encounter wildlife, it’s pretty easy to get excited, isn’t it? It doesn’t happen often, so when you’re lucky enough, the first thing you’re probably thinking is, “wow, I do not want to scare this thing away!” (well, unless it’s a bear or mountain lion, heh).

In that moment of excitement, it’s easy to forget about camera techniques and just start snapping photos from where you’re standing. But, if you want an intimate, sharp, and isolated portrait of any wildlife subject, you’re gonna have to get down to their eye level to snap the photo, and here are some reasons why: [Read more…] about Three Reasons to Photograph Wildlife at Eye Level
