Tone/Value
Now lets just establish the difference between tone and value, as they are very similar and appear to be the same.
Value -- the range of light and dark within either neutrals or colours. Black is at one extreme, white at the other.
Tone -- is a colour mixture where both colours are not of primary hue, not black and not white. This mixture is an intermediate (please refer to my COLOUR blog). In other words, if you were to take a pure colour and add grey, you would have Tone.
To help me understand the basic principles of this element I had to get my head around the terms used when describing tones/values and how to use them. I have added these terms below:
SHADE: A colour (hue) with black added.
TINT: A colour (hue) with white added
TONE: A colour (hue) with grey added
VALUE: The amount of lightness or darkness in colours.
The element of value or tone is, in its simplest form, the juxtaposition (being side by side) of light and dark. It is defined as the intensity of lightness or darkness in anything that is visible.
Balancing all the different values of lidarks, whites and greys is very important when wanting to create a three dimesional object to be portrayed as 3d in a seemingly flat image.
Value in visual arts is the light and darks tones. Lights tones are know as high, dark tones known as low (hence low key and high key)
In art this can be achieved by shading, crosshatch and stippling. I found a great site that explains these techniques click here
I also enjoyed a lesson with my class learning how to create tone and value in flat objects. We were given an object to draw, we had to attempt to draw it and create a 3d image.
Bill our tutor then showed us how to create a 3dimensional rectangle, created by charcoaling shadows. The outcome is demonstrated in my sketchbook
In photography this can be achieved with correct lighting techniques and photoshop, Here is a link to Rembrandt lighting technique as a example introduction-to-rembrandt-lighting-for-portrait-photographers
