Perspective & Photo Challenge

The Art of photography is just as much a challenge as the Skill of photography. Photography hangs in a strange world, a balance between the vision of the artist and the abilities of the equipment. This is another post about the Art of photography. (You can read my last post about the art of photography here.)

Little bug, big world
One of the struggles of artistic photography is to produce images that are more than just physical documentations of the subject. Sometimes this seems easy, but other times it can be more difficult. This begs the question:

How can I push myself to produce more artistic images?

There are, of course, many answers to this question. One thing I would suggest would be to determine what your goals as a photographer are. What are you trying to convey to the viewer? Are you trying to persuade them, amaze them, terrify them? Or are you trying to capture abstract emotions, melancholy, love, peace? It's up to you, but there's very little chance of achieving your goal if you don't have a clear idea of what it is.

So, besides having a "mission statement" for my work, what else can I do?

Photography is, of course, a visual art. Ergo you must force yourself to produce visually unique and captivating images - you will not be able to achieve your goal if no one wants to look at your work. 

Do this exercise.

I've mentioned this somewhere before, but a great trick to force yourself to expand your visual horizons is to constrain your subject matter. What does that mean? Simple: make yourself take 10 (or 5, or 15, or 20) different images of the same subject.

Challenge yourself to think of different "themes" for each shot, and push yourself to demonstrate different aspects of your subject in each frame. This brief series I've done involves a Reduviid nymph (I believe it is a Wheel Bug but I cannot confirm this). Each picture is distinct in evoking emotion in the viewer, although they were all shot on the same morning, at the same location, of the same insect.

When I look at these images together, they form a story (for me) about the Wheel Bug nymph. It's small, but is a ferocious predator (look at that vicious proboscis!), and is patterned beautifully. Other people probably look at them and think, "gross, that looks terrifying, why would anyone go near that thing???"

Well, to each her own. If you aren't that person alluded to above, you may want to check out my post on insect photography here.

What do you think about this challenge? Are you going to try it weekend? (If you do and  you upload your photos somewhere, feel free to leave a link in the comments. I'd love to see!)

Very Small Rocks: Macro Photography Basics

Macro Photography Basics


Baby reduviid 

You may have noticed that I kinda have a thing for arthropods. Okay, maybe not "kind of", but definitely certainly. Quite frankly, I love bugs. And while I believe that insects are amazing photography subjects, I realize that macro photography is not as intuitive as other forms of nature photography. Firstly, you need specialized equipment (should I do a post on this? Let me know). Secondly, you need to understand the technical hang-ups with macro work. Finally, you need to really like small things.

So what even is macro photography?

There is actually a technical definition of a "macro" lens - it must render the subject with a 1:2 or 1:1 reproduction ratio. In other words, the subject must be at least half as large on the film as it is in real life. Make sense? (Note: Some sources only consider 1:1 ratios to be true 'macro', but I believe that this is nitpicking).

Okay, so besides being small, what's the difference?

The main technical difficulty of macro photography is learning how to handle the magnification power of the lens. In short, the extreme magnification creates problems for the photographer.

1. Focusing Problems

At very high magnifications, the depth of field becomes very shallow. Thus it is imperative to focus your images carefully. A few millimeters' change in the focal plane can create entirely different images. Pay close attention that your desired subject is actually the point in the frame you are focusing on. I would recommend using manual focus. As a corollary to this tip, a tripod is helpful in ensuring that you don't accidentally twitch and move your subject out of focus.

You can see in the image above how shallow the depth of field is. Unless this is the look you are going for, I would suggest stopping down to a very small f-stop to maximize your available depth. 
(If the above discussion about depth of field is confusing you, you may want to head over here to read my article about f-stops.)

2. Choosing the Right Subject

I've spoken (and written) before about how I believe there are 3 main components of a good photograph: lighting, subject, and composition. Depending on the type of photography, these individual elements attain greater or lesser importance. For macro photography, I believe that choosing an appropriate subject is paramount.

You should seek out subjects with interesting patterns, textures, or behaviors. Okay, you say, I'm supposed to be doing that anyway. And that's true -  but the key here is to discover subjects that are not easily appreciated with the naked eye. With the magic of your macro lens, you are transporting the viewer to place she cannot otherwise go. In short, your camera becomes a tool with which to expose a hidden world. In my obvious opinion, insects make wonderful macro subjects, as their bodies are etched with color and detail we rarely notice at our native scale.

3. Lighting Difficulties

Because of the issues discussed in tip #1, macro photographers often stop down very far. This results in little available light to shoot with, and thus blurry images. To combat this problem, many photographers choose to use flash to illuminate their macro images. Personally, I prefer the appearance of natural light in photographs. However, if you like flash - go for it! But don't let anyone try to convince you that you "need" expensive lighting gear to undertake macro photography. None of my images are shot with flash.



Parting words:

So there are a few technical challenges posed by macro photography, but they are not insurmountable, even for beginning photographers. Overall, the same basics of light, subject, composition hold true with this, and any, genre of photography. While equipment can be expensive, there are entry-level devices that can help elevate your images to the realm of small (macro lenses are even available for smart phones now). Would you like me to write a post about macro equipment? Let me know in the comments.
In the meantime, it's insect season again! Get out there, and get CLOSE.

If you're interested, in this article, I talk briefly about finding great insect subjects.
