<\/a><\/p>\nLike great Works of Art, the elements in a Photograph need to be arranged in a manner which is interesting and pleasing to the eye.<\/p>\n
In addition, Photography is a two dimensional medium. Therefore we need to make use of the elements which are present in the photo to create a sense of depth and three dimensions.<\/p>\n
Photos also need a main focal point, as well as leading our eyes on a journey through the picture.<\/p>\n
Having these things makes for great photos, which are pleasing to the eye, and we call this \u201cComposition\u201d.<\/p>\n
There are a Number of Composition Rules involving Percentage, Geometry, Symmetry, a Grid of Thirds, and even the “Golden Ratio” and its spiral. <\/p>\n

Photo Composition Rules<\/a><\/p>\n Most people use their camera on \u201cAuto\u201d mode, and get plenty of good pictures.<\/p>\n However, there are many items on a camera which can be adjusted manually to get even better pictures!<\/p>\n In this \u201cHow To\u201d article we introduce several of these camera settings, and show how they can be used to create quality photos. <\/p>\n An overview of the three main Variables: “ISO Light Sensitivity”, “Aperture”, and “Shutter Speed” is provided. <\/p>\n This provides the preliminary background to more detailed articles on each of these three key items.<\/p>\n It is therefore vitally important to read this article before proceeding forward to the specific detailed articles. <\/p>\n To read the Introductory Article about Camera Settings, click the link below. <\/p>\n Digital Camera Settings<\/a><\/p>\n ISO sets a Camera\u2019s sensitivity to light<\/p>\n Effectively it works like a Brightness Control on your camera, and you can turn it up higher if you are in a dark room, or in a shady forest. <\/p>\n If you are in Bright Sunlight, then you need to turn the ISO down to a low value or else your photo will come out all white and washed out with too much brightness. <\/p>\n Camera ISO is one of the three key Variables of Photography, the other two being Aperture and Shutter Speed.<\/p>\n Every photographer needs to understand ISO in order to get bright and clear pictures from their equipment.<\/p>\n The ISO sequence is: 100, 200, 400, 800, 1600, 3200, 6400 and etc. For every step up in this scale, the brightness of your picture doubles. <\/p>\n To get the full story on ISO and how to set it correctly on Digital Cameras for a variety of lighting conditions, click the link below. <\/p>\n How to Do ISO<\/a><\/p>\n Aperture is one of the key variables in Digital Photography. The other two are ISO Light Sensitivity and Shutter Speed.<\/p>\n An understanding of Aperture is critically important to isolate subjects in portraits and get full detail in Landscape pictures.<\/p>\n The Aperture Scale consists of a seemingly odd set of decimal and whole numbers, and getting your head around these values is not at all easy for Beginner Photographers.<\/p>\n In this article we examine Aperture in detail, and mathematically explain where the Aperture \u201cf-numbers\u201d come from. <\/p>\n Click the following link to read the full article. <\/p>\n How To Do Aperture<\/a><\/p>\n Shutter Speed is mainly used for creating dramatic effects by either freezing action or blurring motion.<\/p>\n The Speed is expressed in a fraction of a second, and is how long we let light in through the camera lens to the sensor. <\/p>\n Think of the Shutter as like opening and closing a set of venetian blinds quickly to let a burst of light into a darkened room. <\/p>\n Shutter Speed, (also called \u201cExposure Time\u201d), becomes critically important in situations outside of the norm, such as the following:<\/p>\n 1) Fast Moving Sports Action<\/p>\n 2) Dimly lit indoor areas such as Bars and Clubs<\/p>\n 3) Night Time Photography<\/p>\n 4) Theatre and Musical Performances<\/p>\n 5) Indoor Photos using Flash<\/p>\n 6) Indoors Photos where we do not use Flash<\/p>\n 7) Photos where we want motion blur for fast moving objects<\/p>\n 8) Bird and Wildlife Photography<\/p>\n 9) Photographing Young Children and Animals<\/p>\n In this article we will show you what Shutter Speed is, what the speed numbers mean, and how to set shutter speeds to values which should produce great photos.<\/p>\n Click the following link to read our article on Shutter Speed. <\/p>\n How To Do Shutter Speed<\/a><\/p>\n Different light sources produce light with slightly different colour tints, but our eyes do a great job correcting these variations.<\/p>\n Humans do not see a shift in colour as we move from a sunny garden into a shaded area, or go into a room and turn a light on.<\/p>\n Generally wherever we are, a piece of plain white paper always looks white.<\/p>\n However Digital Cameras DO detect light source differences, and sometimes create pictures with incorrect looking colours in them.<\/p>\n We need to know how to perform \u201cwhite balance\u201d adjustments, so that we can obtain pictures with realistic colours in them.<\/p>\n White Balance involves the Primary Colours of the Spectrum forming a Kelvin Temperature Scale from “cool” blue\/violet through to warm “red” candle light. <\/p>\n What we have is a Mathematical Scale of color, and White Balance blends various colours together so that a white sheet of paper will look white, no matter what coloured lighting we are in. <\/p>\n You can read the full article on White Balance at the following link: <\/p>\n How To Do White Balance<\/a><\/p>\n In this article we look at Combining Variables for Correct \u201cExposure\u201d. <\/p>\n We tie together the three key Digital Camera Variables: ISO, Shutter Speed, and Aperture, and discuss how to set these up to get good exposures in Camera Manual Mode.<\/p>\n When these three variables are optimised and unified together, we get a nice clear picture with great contrast and highlights. We say that the photo is correctly \u201cExposed\u201d.<\/p>\n You can read the full article on Getting Correct Exposure Using Key Variables at the following link:<\/p>\n Combining Variables for Correct Exposure<\/a><\/p>\n
