Photoshop Tutorial

Today I had my first photoshop tutorial and I found out some interesting things that I didn't previously know. Firstly we looked into colour, and tonal ranges. 

We looked into the artist Chuck Close an American painter did photo realistic drawings but then become disabled and was confined to a wheel chair so he then started painting in colour using tone. 

In the image above on the right is an image go the painting up close, the paintings are made up as squares in a grid which makes it have a pixilated feel. The blobs of colours in different tones builds up the image, and when you stand back from these huge paintings you can see the face, and aprestiate the time that has gone into them. 

Image resolution  

Image resolution is the detail an image holds. The term applies to raster digital images, film images, and other types of images. Higher resolution means more image detail. Image resolution can be measured in various ways. 

Image pixels 

The image itself is composed of pixels in a series of rows and columns. The size of each pixel depends on the size the image is displayed. A smaller image size will have larger pixels and a larger image size will have smaller pixels.

Most important part of photoshop is image size, you have to always know what size image you are working with, this is important for when you come to print it. To do this select image then image size. 

RGB Color Mode

RGB is the color scheme that is associated with electronic displays, such as CRT, LCD monitors, digital cameras and scanners. It is an additive type of color mode, that combines the primary colors, red, green and blue, in various degrees to create a variety of different colors. When all three of the colors are combined and displayed to their full extent, the result is a pure white. When all three colors are combined to the lowest degree, or value, the result is black. Software such as photo editing programs use the RGB color mode because it offers the widest range of colors.

CMYK Color Mode

Printers print color onto paper using the CMYK color mode only. This is a four color mode that utilizes the colors cyan, magenta, yellow and black in various amounts to create all of the necessary colors when printing images. It is a subtractive process, which means that each additional unique color means more light is removed, or absorbed, to create colors. When the first three colors are added together, the result is not pure black, but rather a very dark brown. The K color, or black, is used to completely remove light from the printed picture, which is why the eye perceives the color as black.

Colour Gamut

We learnt about levels and curves, but the most interesting and useful thing I found out is on the colour picker and when choosing colours the exclamation mark indicates that the colour witll not actually print that colour, and the one below is web colours.
