Composition is probably the single most important aspect in achieving "pleasing" results. There are thousands of books and such on the "rules" of composition. There is no way for me to explain all of this in this short post. But I shall teach you a "trick" that will help you achieve fantastic results. Open ANY MAGAZINE...now look, carefully at each image. Chances are, that photo was taken or drawn by a "pro". Study it, ask your self questions. Learn to study every image, in detail. Where is the light coming from. What angle is being used? Where is the camera? Low? High? waist level ?? This of course takes much practice and disipline. Learn to open your eyes and absorb everything. Framing your image within the eyepiece is a must to learn. Practice Practice Practice.... there are no shortcuts to experience! Learn how to compose your shots as to draw viewers to the important part of the image that you want to emphasis.
Of course you can always grab a book and read. . . "we live in a visual world now"!! Learn to study images in magazines and books and you will catch on. WE all learn... by making the same mistakes and growing from there.. through much practice and determination. Most people try to include tooo much in the view finder. FILL THE FRAME.........with detail !! get closer!! Instead of taking a picture of that bicycle, just get closer to the chain and look at the design, practice these principles and I guarantee you exciting images!! CREATE !!!
