Design Practice: Photoshop Workshop

Non destructive editing, creates layers so they can be edited/ changed later, rather than permanently changing the image.

Output- How image will be used for the final presentaion eg. print, poster, screen.

Bitmap graphics- Photoshop works with made out of tiny squares pixels. Not like illustrator vector graphics. not a mathematical equation, it is the size that you create it to be.

Because photoshop works with bitmap graphics, you have to make sure you set up the resolution correctly and select the appropriate format for what the final work will be used for the average eye can not determine pixel 1/300 of an inch

These have to be a higher resolution then 300 pixels/inch.

Colour profile:

If you are designing an image for screen it should be designed for 72 pixels/inch

When creating for screen the colour is made out of light, specifically RED GREEN BLUE

Where as colour for print isn't made of light and should be cmyk, CYAN, MAGENTA, YELLOW and BLACK

Colours that are created by RGB light can't always be reproduced by CMYK printing.

One way to change the mode of the image is the way shown above, however this is a destructive editing tool, and can't be reversed.

Proofing Image:

A proof image is a mock up or test at how something will look when finished.It is no destructive and can easily be reversed. This is useful in graphic design as it is how you work in partnership with the client.

Gamut- The full range eg. colour gamut. If something is out of gamut it means that the colours used are out of the colour range. It gives us a visual representation of the colours you of gamut and helps assist bring the colours in to gamut in a none destruction way.

Because the gamut range is so out of range, something drastic has to be done, so we went adjustment layer>hue/saturation.

First we lowered the saturation of the image, the colours bright blue and green are ofter out of the gamut colour of CMYK. So we adjusted the hue. The colour red shows a lot more detail and brightness.

The triangle pointers show shadow, mid tones and highlights.

This subsequently adds to much light to the window section and detail is lost there for we use the mask tool by selecting the paint brush and making sure the foreground colour is black, then you erase the sections of the light to make them darker again. It is both none destructive and dynamic.
