Wide Angle vs. Telephoto - Which is better?
Most professional photographers have learned about shorter focal length (wide angle lenses) and long focal length (telephoto lenses). There may be debates between different photographers as to which one is best but like everything it is all down to personal choice as to which one you like best.
There are many experts who may say that a wide angle length doesn't necessarily give more depth of field. It is possible for you to try this out for yourself. If you are an accomplished photographer, what impact will it have on your work? Let's not forget that this may be so if you keep the size of the picture constant. It is possible for you to take a picture of a subject using telephoto then zoom out and compare the difference with the wide angle lens.
Maybe you are going to take a shoot of some really amazing scenery, perhaps a mountainous landscape, with amazing colored sunlight. Try using the telephoto setting and zoom in, after which you can then zoom out and take a picture with the wide angle setting. When using the Canon wide angle lens, you will automatically expect there to be more depth of field in the last photo and that’s what it will look like. However, if you enlarge the photo, the depth of field may disappear.
There are many who will zoom out to get more in their picture using a wide angle setting. Often though, by doing this, the objects may look smaller. If you zoom in on a particular subject you want in the picture, you will lose depth of field. By zooming in and out and varying the focal length setting, you have the perception that the depth of field is variable.
It may therefore appear that by using a wide angle lens (such as Canon wide angle lens) will give you more depth of field if compared to using a telephoto. It is true to say that whatever a person is happy with when taking photographs it is all down to personal choice as to what they like and know best and are happy with.

Percept (Artificial Intelligence) $79.66 High Quality Content by WIKIPEDIA articles A percept is the input that an intelligent agent is perceiving at any given moment. It is essentially the same concept as a percept in psychology, except that it is being perceived not by the brain but by the agent. A percept is detected by a sensor, often a camera, processed accordingly, and acted upon by an actuator. Each percept is added to a percept sequence, which is a complete history of each percept ever detected. An intelligent agent chooses how to act not only based on the current percept, but the percept sequence. The next action is chosen by the agent function, which maps every percept to an action. For example, if a camera were to record a gesture, the agent would process the percepts, calculate the corresponding spatial vectors, examine its percept history, and use the agent program (the application of the agent function) to act accordingly.

Percept (Information Technology) $86.03 High Quality Content by WIKIPEDIA articles A percept in the information technology industry is a term used in the pricing of data transfer. For example, rather than charging an individual (who is remotely retrieving data from say a weather sensor or a GPS device) by the size of the data, a company would charge that individual by the percept. Here a percept would constitute a statistical data point, such as a GPS location. Pricing per percept would mean that a customer or individual using that GPS device would actually be charged per unit of true economic value to him/her, a GPS location datapoint, rather than on the size of that datapoint in bits/bytes/kilobytes, etc. Author: Surhone, Lambert M./ Tennoe, Mariam T./ Henssonow, Susan F. Binding Type: Paperback Number of Pages: 108 Publication Date: 2010/10/07 Language: English Dimensions: 6.00 x 9.02 x 0.26 inches |

Percept, Decision, Action $195 Seemingly simple behaviours turn out, on reflection, to be discouragingly complex. For many years, cognitive operations such as sensation, perception, comparing percepts to stored models (short-term and long-term memory), decision-making and planning of actions were treated by most neuroscientists as separate areas of research. This was not because the neuroscience community believed these operations to act independently—it is intuitive that any common cognitive process seamlessly interweaves these operations—but because too little was known about the individual processes constituting the full behaviour, and experimental paradigms and data collection methods were not sufficiently well developed to put the processes in sequence in any controlled manner. These limitations are now being overcome in the leading cognitive neuroscience laboratories, and this book is a timely summary of the current state of the art. The theme of the book is how the brain uses sensory information to develop and decide upon the appropriate action, and how the brain determines the appropriate action to optimize the collection of new sensory information. It addresses several key questions. How are percepts built up in the cortex and how are judgments of the percept made? In what way does information flow within and between cortical regions, and what is accomplished by successive (and reverberating) stages of processing? How are decisions made about the percept subsequently acted upon, through their conversion to a response according to the learned criterion for action? How does the predicted or expected sensation interact with the actual incoming flow of sensory signals?  The chapters and discussions in the book reveal how answering these questions requires an understanding of sensory–motor loops: our perception of the world drives new actions, and the actions undertaken at any moment lead to a new ‘view’ of the world. This book is a fascinating read for all clinical and experimental psychologists  and neuroscientists, as well as anyone interested in how we perceive the world and act within it. |
