Getting The Most Out Of Your Camera

Have you ever found yourself in a situation and wishing you had a hot shoe flash with you? Well being the biggest “anti-flash fan” you know of (I’m just kidding! I’m not “anti-flash”. My concern and talking point is a caution against built-in flashes.) I have some things for you to look into if you are interested in getting just a little bit more out of your camera’s performance.

Having used my equipment in a lot of situations with varied amounts of lighting, I became very dissatisfied with blurry photos. So, in an effort to understand more about the performance of my camera and lenses, I began searching for methods of shooting without a flash and blur.

As I began my search I discovered that when shooting black & white (monochrome) pictures, my camera was more sensitive in lower lighted areas giving me the capability to shoot with a faster shutter speed.

At the same time, I did not want to only shooting black & white (monochrome) photos in low light, so how can I get around this problem? Some cameras come with editing software. Canon provides “Canon Utilities Software” with their SLR cameras, so there may be comparable software with other camera brands. In “Canon Utilities Software” post-exposure changes are possible by reading the EXIF data from the photo and altering the information in a new file temporarily stored in a separate data file.

However, before I prattle too far afield of my given topic, my point of shooting black & white (monochrome) photos to avoid needing to add light; the picture style can be changed in the editing process of “Canon Utilities Software”. What this mean is black & white (monochrome) shots can be change into color shots!

The camera takes the information of colors with each black & white (monochrome) shot, however not as it would when shooting in color. Do not be surprised when changing picture styles that the color is not as vibrant as when shooting in other pictures styles.

More on picture styles and black & white shooting in Part 2.

Camera Troubles – Part 5

There is one more part of the human Eye and camera that we have not covered. This is the process of the Data Transfer from the Sensor to the Storage media via the Processor.

The Data Transfer:

The human capability for vision is amazing because we think we understand it enough to duplicate the process, only to realize our duplication is much less efficient than our inspiration.

As soon as our Retina receives the light of our surroundings, beginning to send the neurological impulses to the Optic Nerve there is a process of Data Transfer initiated. The amazing thing about this Data Transfer is the amount of detail that can be recalled, or amounts of certain information which one can be trained to receive and recall.

Illustration of information recall: Military branches train their personnel to acquire a target and discern in an instant if it is friendly or hostile. After an operation, begin the reports from each member and with it the lists of information that is most important; number of personnel on the operation, enemy patrols encountered, branches to which the patrols are affiliated, shots fired, number of injuries…etc. There is a lot of information to take in with precious little time to do so. This information is primarily accumulated by sight and secondarily with the other 4 human senses.

The same for public servants. Police officers require the use of sight in making reports besides assessing the threat to the public and their own safety. Paramedics make reports with vital statistics of a patient from many different senses at the same time. Firemen and women are trained to take verbal queues before getting to the scene of an emergency to take their own assessment of the situation.

This is all gathering data. These mentioned public servants and military are trained not just to gather information but to recall it for the purpose of reporting the events as they happened. This Data is what I draw upon in likening it to the Data a camera receives.

When the sequence in a camera is initiated, the light received by the Sensor is converted into Data which is transferred  across thin metal conductors. However, here is where Data loss becomes a problem. The Sensor is made up of millions of little pixels which receive light. There is not adequate space to give each pixel its own dedicated metal conductor for Data Transfer, so there ends up being about 100,000 or more pixels attached to 1 metal conductor lead.

Even still it is incredible that with so much Data being Transferred there is not more Data loss in digital cameras.

In the next and last post for the “Camera Troubles” series, we will discuss the specifics of the digital camera limitations so that we can learn to capture the detail we want.

Camera Troubles – Part 4

With this basic knowledge we have built on the human Eye and how the camera lens was designed from the model of the Eye, I would like to venture into some observations of human vision.

Again please take note of my disclaimer from Camera Troubles, “I am not an Optometrist”, so I am not attempting to prove anything for or against medical science but observing our ability and capability.

We have some magnificent capabilities to see detail in deep shadows while focused on well-lit objects. It is in fact this ability that I find most fascinating, because I have tried to  figure out whether I had looked into the shadows subconsciously noting the detail or if I am seeing that wide a spectrum of detail. In either case, the ability to see the wide range of detail in light or shade is a characteristic that I have not yet found innate within a camera, but I find it most common in creatively thinking people.

There are some ways to achieve the look of detail in shadow while focusing on the lit focal point. Before going to the topic of how the camera see a scene, we would do well to better understand what and how we see.

I have a hard time discerning the varying degrees of light and how well the area is lit where I am shooting. This I know from experience and so now I take some test pictures before getting into the heat of the photo shoot. This tells me some amazing things about my Eye sight. The Iris opening so wide that I do not notice the slight shadows between light fixtures and my Brain filling-in details of the wall paneling. We have an awesome device in our Brain to automatically fill-in such detail! Thank God for giving us such magnificence to be used and shared!

Now we have not discussed the process in-depth of taking the photo after exposure from the Sensor to Storage. So in the next posts in this series, I plan to explore “The Data Transfer” and “What the camera sees of what I do.”

The Make-up Of An HDR Photo

This is a completed HDR photo. When making a HDR, you want to add to each element. Be careful not to detract from the photo's statement. In this photo the ray of sunlight on the rock is part of the statement, being "the viewer is in a safe place and cool shade" and still maintaining the cheerful bright awareness of the sun. More details are given in the article below.

Welcome to 2012! I hope the Christmas and New years celebrations were enjoyable and filled with family and friends.

In the tender start of this new year, we began discussing the techniques of photography. We like new perspectives and informative articles, but only when simultaneously woven together in artful story form.

There are so many “HDR tutorials” out there that searching “How to make a HDR photo in (your favorite program here)” will bring one or more tutorials! So I do not intend to make this another tutorial, rather I desire to give some thoughts and insight into what make an HDR photo so impressive.

What creates that “wow” factor in the HDR photos I see? From observation of and experience in photography, a photo well made will have the most detail in the moderate range with light and shadowed areas. The technique of using a High Dynamic Range (speaking strictly of light) is designed to add detail to the light and shadowed areas.

Illustrating what I mean by adding detail to areas of light and shadow, this side-show gives you and idea of what each layer of the HDR image brings to the completed work.

The basic theory is adding detail to the light and shadowed area of the photo, but the HDR technique adds to much more than simply expanding the detail by diversifying the amount of light between image layers. The High Dynamic Range adds more to a photo in color, definition and detail. Light is central to these three things, but when we speak in terms of light, my mind begins to construct a black and white image in which to better understand the use of light. HDRs add much more than blacks and whites to an image. Light expounds the color spectrum, and this is the basic foundation of a HDR photo.

This is why it will be hard to explain every detail of the HDR technique, because light is the core and many scientists admit that they can not define light, but only explain some of what it does for us.

Here is a parting thought: “That which we have seen and heard declare we unto you, that ye also may have fellowship with us: and truly our fellowship is with the Father, and with his Son Jesus Christ. And these things write we unto you, that your joy may be full. This then is the message which we have heard of him, and declare unto you, that God is light, and in him is no darkness at all.” (Found in the First Epistle of John; chapter 1 verses 3-5.)

Amazing!
