Basic Image Parameters In Digital Photography
In this photography online course, we will be learning the basic image parameters in digital photography and digital cameras.
They are:
Hue, Saturation, Contrast, Sharpness, Tone and Color space
For better digital camera image superiority and for better digital photography you can manipulate these image parameters and enhance your photography. But you must also realize that the best option is always to take a photograph in RAW file option and tweak it using image-editing softwares.
Tweaking features offered by some brands:
Some brands of digital cameras do have some integral tweaking features which you may use if you have one of them.
Some of these are:
Nikon D300 and Nikon D400 allow tweaking parameters by settings for individual parameters and presets.
Konika Minolta A2 has bracketing preferences for the image parameters. It allows you take the same picture image using different parameters.
Canon EOS 30D allows several tone and saturation settings.
Nikon Coolpix P50 and Canon Powershot SD850 IS have the option for lighter and darker skin tones.
The concept of color space:
A color space is a model used by computers to map color, using numbers. Basically, there are two types of color spaces, RGB and CMYK. RGB is also called as additive color space and CMYK is also called as subtractive color space.
Additive color spaces are used on displays and screens, a combination of colors giving appearance to a particular color.
Subtractive color spaces are used in printing applications. To get a particular color, another
color has to be subtracted from the white substrate so that the reflected light can be perceived to be a specific color.
In additive color space, screen emits a light using a combination of different lights whereas in subtractive color space, the surface of printed paper absorbs all wavelengths except the color that needs to be perceived.
Many dSLR cameras use RGB color space. Before getting a photo printed, it is always a good idea to convert it into CMYK color space so that you may know the exact result you will be getting after it is printed.
Even if you don’t change the color space to CMYK, computer programs do it before printing.
Color spaces are defined in computer programs using hue, saturation and brightness as defining guides. RGB model includes HSL (Hue, Saturation and Lightness) and HSV (Hue, Saturation and Value).
