In the early days of photography, photographers had no choice but to shoot in black and white, as it was the only available medium. Then, in 1936, the invention of kodachrome gave colour photography to the world. But black and white photography didn't die off, instead it flourished. Modern black and white photography at it's best is art, and many photographers regard it as the purest form of photography.
Just hearing the words 'white balance' is usually enough to strike fear into the heart of even the most hardened of amateur photographers. After all, it sounds so technical, so it must be complicated, right?
Most serious photo-editing programs let you use a histogram as a guide when editing your images. However, since most image corrections can be diagnosed by looking at a histogram, it helps to look at it while still in a position to reshoot the image.
In this tutorial we would like to focus on the most essential technique of: Photographing Bottles on White Background. Different beverages require unique approach based on consistency and color of beverage and the shape of the bottle. In this tutorial we selected a group of classic low shoulder red wine bottles.
Color is a visual property of perception. Camera chip interprets the light that passes through the lens in a similar way as our brain interprets the light passing through our eyes. Our perception of color is a result of the journey undertaken by light.
Light travels from the light source onto an object and then it bounces off the object and continues to travels through our eyes onto receptors. Then information received is processed by the brain. The brain, being very considerate of our psyche, it balances the color of the light to a white point (simulating daylight).
The camera works in a similar manner as the human eye + brain: the light enters the lens and falls onto sensor and then the data gets processed and the software/firmware assigns corresponding values based on camera settings.
