OUGD405 - Adobe Photoshop Workshop

The basics of Photoshop

  • Learning how to use Photoshop in the most economical and efficient way

At the start of the session we spoke about the most appropriate way to brighten the mosaic. 

We were then told how to set up a document to be appropriate for our work.

We were told to never increase the scale of work created, therefore we have to have in mind what the size of the document needs to be for the end result. 

We have to constantly relate back to the output. 

We will always be made aware of the size because no matter what we will always have a brief stating what the output is.

There are 300 pixels making up an inch.

When you print large scale everything is split into sections known as sheets.

A billboard is 48 sheets and therefore we would use a higher resolution.

The screen only has 72 pixels making up each inch. 

There are now different resolutions for screen and screens are now actually 96 pixels per inch.

This hasn't been changed because Graphic Designers don't like change.

Ultimately working in the industry you would never use images taken from Google because they are 72 pixels per inch.

  • If you are printing something CMYK 

  • If designing for screen RGB

If we start with CMYK and wanted to display it at RGB we can't because the colours have been eliminated.

Three main things to set up:

The size
The resolution
The colour mode

Photograph taken with an SLR camera. The colour will always be in RGB. You are capturing it on to storage, capturing light. A camera cannot capture image with CMYK. A printer cannot reproduce these colours using the CMYK colour mode. As a graphic designer we should never be surprised with the finished product. All graphic designers are perfectionists and therefore when printed things should look exactly how they look on screen. 

By changing the format to CMYK it makes the photograph appear dull and the quality is reduced. By turning it into CMYK is has been destroyed, making it a destructive transformation.

By going on 'view' and then 'proof setup' it enables us to test what it is going to look like when it is printed. In the professional printing process you work with separating colours with four different plates. Within this setting we can see what this looks like. We should have ultimate control over what we do.

The Gamut is the range of colours that a specific model is capable of producing.

This was the outcome of the Gamut selection.

Adjustment layer creates a new layer so that we don't ruin the quality of the original image.


Increased hue

Shadows, mid tones and highlights (each triangle represents these). 

Adjustment laters using the brush tool.

This is the original photograph.

Here I have used the quick selection tool to highlight the foreground image.

I then dragged the third triangle to the left to make the image stand out in a way which enhances the quality and makes the sky stand out.

This setting allows Photoshop to do the work for us.

Above is the process whereby I merged three images together.
