Being new to this forum, I would like to say hello, and that I’ve spent some time reading a few of the current topics and really enjoy the posts. I can see that there are quite a few very knowledgeable photographers here. Actually, it’s pretty intimidating. I see that most people take an interest in a specific genre of photography, and then learn and grow in that area. I read the topic about the major new upcoming event and am looking forward to reading the articles. I can't think of a better way to gain insight than to read what is going through the photographers mind when planning a photo. My question is, what is the best approach to taking a photograph? Or, does that depend on what the subject is? I have a serious roadblock of being able to visualize what I’m trying to show in an image. I imagine that a gifted photographer can see in their mind exactly what it is that they want to portray in an image before they even take the picture. That must be the hardest thing of all to learn. I'm interested in learning more about taking photos of nature and landscapes, but not only that. Right now I feel I’m stuck with a blank canvas, thus the title of the post.
First, if you are unaware of your personality type, you might want to explore just how you function. Many professions, those in the sales, education and medical fields in particular, will learn how to find another person's basic operating mode so they might best know how to approach any one person. Or to know when that person is feeding them a line of BS.
In general, people fall into one of three very broad categories here; visual, auditory or kinesthetic. Let's say I am a sales person discussing a potential buy with you as a client. If I determine your motivations come in a kinesthetic manner, I will have you handling and operating the merchandise as much as possible since you take in information by way of feel. An auditory personality suggests you will mostly hear my words as I emphasize specific details which I feel are more important than a mere physical presentation. Finally, a visual personality type will see and explore the patterns of the merchandise. These are people who tend to see patterns in everything.
These are generic descriptions and each individual tends to have a mixture of all aspects with one being the most predominant. But a salesperson or educator would be unwise to ignore the signals a client/student gives off for how they want a presentation to be made.
Should your personality type be outside of the visual sort, then right now you are quite likely not as quick to pick up on patterns, shapes, lines, contrasting elements and so forth which make up the basics of "composition". This might be a simple explanation for your "blank canvas" state of mind. As with any hobby, it would be best to recognize your weaknesses and work on those specifics which will strengthen your overall game. There are online personality tests which can assist you in determining your strengths.
If your personality is not based on visual clues, then you must put your attention on developing your sense of composition.
"Artistic visualization" is, IMO, a bit of a misnomer when it comes to photography. If you are primarily a visually oriented person, then you have the natural ability to see patterns and possible images in the most mundane subjects. If you are not that sort of personality, then you do not see in the same manner. You can't really alter your basic personality type, you can only work to gain more capability to comprehend the rules of another presentation style. If you are a kinesthetic or auditory personality, in most cases simply looking at great photos won't provide any strong clues as to why the shot is considered good.
This does not mean you cannot learn how to see a possible composition. You should though approach the learning process in the manner which best suits your personality. An auditory personality will learn best when the lessons are done by someone instructing you, say, on youtube or in person with an emphasis on the spoken word. Explaining a piece of art and how it operates will likely work best for that personality type. Possibly, a short course in composition is best if you have an instructor to guide you.
If you are a "feel" type, learning the operation of your camera and putting your knowledge of how a shot is put together in a technical sense might be best for you. In other words, rather than looking and "seeing" a composition, you might find an interesting subject and then explore in your mind just how the camera's operation could make that an even more interesting image. Hands on work is typically best for the kinesthetic personality. Take you camera and explore the variables the camera allows.
Since no one is purely this or that personality type, you can train yourself to become better at the other values. You do, however, have to approach the subject with how you best learn in mind.
