Space Management - III

I have discussed the space definition and camera position relative to space. In this one I have wrote my ideas regarding the lenses and how they affect the spce, wide angle and telephoto lens.When we use a wide-angle lens, we are expanding all visually space. For creating visual depth, the expansion supports the concept of layering by extending all the spaces. The visual expansion of space is based directly on distance relationships, between elements in the frame and the camera's position. If... continue reading

Space Management - II

Camera position plays a vital role in creating and arranging positive and negative spaces. The relationship between where the camera is positioned and where the elements in frame physically exist is one of the most important things we should pay attention too. Their are three components of the cameras position in relation to the elements in the frame, the vertical position, horizontal position and the distance to the subject (moving closer or further away).When we raise or lower our camera'... continue reading

Space Management - I

Using Space Management and Layering, we manipulate the two dimensional photographic space and introduce depth by changing the relationship of distance between elements and their size.Positive and negative space occupies all areas within any scene in the camera's viewfinder. Positive space is simply, the space the elements or subjects occupy within the frame; Main subjects is the positive space that visually is the most important element in the frame and Secondary Subjects are all other positive... continue reading

Exposure and Tonal Contrast

Correct Exposure is combination of Shutter Speed, Aperture and ISO and a creatively correct exposure is combination of all of above and the photographer’s creative mind. I believe there is nothing can be termed as bad or good light for my exposure, it should be appropriate light as well as exposure. Lighting depends on Seasons, Weather, and Time of the day. The essential qualities of light are direction, color and intensity. I have often realized that waiting for the perfect moment and animal behavior... continue reading

Focus on Auto Focus

Here are my options,1. Use Predictive focus and follow the bird and on the decisive moment press the shutter. The disadvantage is you should know the bird’s behavior completely, otherwise the decisive moment will after the bird will go out of range. Good option for egrets and herons etc.2. Focus to place where you know the bird will come or fly through. Wait for the bird to come and press the shutter at right time. Disadvantage you have to keep your eye fixed with viewfinder and... continue reading

Exposure, Shutter, Aperture and Background

Lot of time we face problems while taking picture because of cluttered background and bokeh lights. I have devised for myself few rules that help me to get rid of these things,1. Depending upon the light, I narrow the aperture that is increase the f number and also sometime use flash along with small aperture. Small Aperture not only increases the DOF, it also reduces the light so if the background consists of clutter bush etc, then all these gets hidden and the fill in flash makes the subject evenly... continue reading

Exposure compensation and Metering mode

In lots of article and books I have seen that exposure compensation depends on the color, and of course 18% grey and blah blah. Now, my realization is it also depends on the metering mode. Let say your metering mode is Spot, so you just need to worry about 2-3 % of the image, if its evaluative or matrix then you need worry about the complete image, 100%. So in case Sport your headache is less as you are worrying about only a tiny portion of your picture and in case evaluative you should worry about... continue reading
