Quick Tip for Getting Sharper Closeup Photos

In a previous post, I explained a quick way you can get sharper photos by adjusting the “picture style” on your DSLR (if you’re shooting in JPEG). Well, another small way you can make your closeup photos appear sharper is by photographing your subject in front of a contrasting background.

The photo above is a good example. The dragonfly is pretty bright, but the background is much darker. This strong contrast of brightness helps emphasize the edges, making the outline of the dragonfly appear much sharper.

This is actually how most sharpening algorithms work in post-processing software: by increasing the contrast of brightness between edges it makes those edges stand out more and appear sharper. That’s why oversharpened images have those ugly halos. [Read more...]

How to Photograph Wildflowers with Flash

Note from Steve: This is a guest post written by Rob Neave, of Perth, Western Australia. In this post he talks about an interesting technique for photographing wildflowers with flash.

As always, if youʼre also interested in writing a guest post, please feel free to contact me. Thanks!

My state of Western Australia is wildflower central for the known universe. For years, I was entranced by their potential as photographic subjects, but could not figure out how to do it. Eventually I bought a book called “Field Photography” by Alfred A Blaker, which showed me how to get decent shots of wildflowers.

Although the techniques presented in Blaker’s book were originally written for film photography, I have been able to also apply them to digital photography and ETTL flash.

The photo above is an example of what you’ll be able to do with these techniques. The flowers in the photo are Blue Lechenaultia. This image shows the detail and depth of field (DOF) we can get with these techniques. It was shot at f/32 and 1/200 with flash. [Read more...]

Why the Sharpest Photo Isn’t Always the Best Photo

Desert Sunflower @ f5.6 / Photo by Steve Berardi

As nature photographers, we tend to have an obsession with tack sharp photos and will do almost anything to increase the sharpness just a tiny bit. After all, looking up close at a sharp photo of a dragonfly is one of the greatest rewards of photographing the natural world

But, sometimes it’s necessary to sacrifice a little sharpness for a better composition.

As an example, consider the photo above of a Desert Sunflower in front of a patch of Desert Sand Verbena (see original size photo too). There are three reasons why the sunflower isn’t as sharp as it could have been:

The wind was blowing pretty hard, and constantly swaying the flower

The camera’s sensor was not parallel to the most important plane of the flower

A pretty large aperture was used (f/5.6), which limited depth of field

Of course, the wind was out of my control, so all I could do for that was wait for the calmest moment possible. But, the other two were in my control. Why didn’t I address these problems? [Read more...]

9 tips for photographing wildflowers with a point and shoot camera

Photo by Steve Berardi (shot with a Canon G10 point and shoot camera)

Although wildflowers are best photographed with an SLR camera, it’s still possible to take some pretty good shots with a plain old point and shoot camera. And, sometimes this may be the only camera you have with you at the time, either because you’re backpacking far into the wilderness and want to travel light, or maybe you haven’t made the jump to an SLR just yet.

The biggest problem you’ll run into with the point and shoot camera is the large depth of field you get from the super small sensor. This limits some of your options, but there’s a few ways to get around it, and as always, light also plays a huge role in the success of a photo.

So, here are a few tips for photographing wildflowers when you’re limited to a point and shoot camera: [Read more...]

How to create intimate portraits of nature

Bigelow's Monkeyflower / Photos by Steve Berardi

Which of the two photos above do you like better?

They were both taken of the same flower, with the same camera settings. The only difference between the two shots is the position of the camera.

I’ll take a wild guess that you like the first one more. And, I think this photo is better because it has more of an intimate and friendly feeling to it. [Read more...]

3 things that affect depth of field

I was planning to write about the three things that affect depth of field this week, but by pure coincidence (seriously!), I discovered this great blog post that Brian Auer wrote a few days ago:

Three Ways to Control Depth of Field

I’d highly recommend checking it out. Brian did a nice job of explaining the three things that affect depth of field (aperture, camera to subject distance, and focal length), including some sample images too.

There’s a few things I’d like to add though: [Read more...]
