Unit 35: Task 4: D2

Task 4

D2

All the work you complete needs to be archived, should customers want re-prints or alterations.

Graphic images take up huge amounts of space and you need to find the best methods for saving images in a format that:

• Is a suitable image quality for the type of purpose
• Is small in MB size (think about compression techniques)
• Is the right resolution for the purpose
• Has a suitable colour depth

You need to write an instruction guide for saving images for the purposes mentioned in P2.

So in conclusion a ‘how to save guide’ for:

1. Internet graphics
2. Large format graphics
3. Leaflet suitable graphics.

MB-Megabyte
MP-Megapixel

How to save:

Internet Graphics:

-JPEG (Used in saving images). It is a photo-type image on the Web and has many compression levels. Joint Photographic Experts Group.  JPEG images for internet graphics as these contain pixels which can be either compressed or enlarged to produce good graphics.JPEG files usually involve reduction of size to the original creating a pixelated image.  It is best to use files such as JPEG to create internet graphics as compared to other file formats such as GIF which is used for logos JPEG images are easier to upload to the internet as an image. PNG would also be a good format to save internet graphics in. PNG (A webs graphic file format which has more feature available than GIF and JPEG). Portable Network Graphics. The example of screen shots below displays the variation between the different types of file formats available to save. It shows the quality of a JPEG image, due to it being a lossy image it had better quality and resolution in comparison to the GIF file which is a non-lossy image which shows pixels and a bad image resolution. 

Large Format Graphics:

- PSB saves images in large formats as a save option. This is a format used in photoshop to save images with a larger resolution and compress colours well as a large format. Only available to Adobe software, saves as a large file and takes up a lot of space. This can be viewed in photoshop in the save options: when you click file and save as then adjust the file type to PSB or large format images. PSB files tend to be large documents that are for large image sizes. PSB allows images to be saved at up to 300,000 x 300,000 pixels (a larger format - better resolution), they can also be opened as photoshop images or exported to be viewed as a Tiff formatted image depending on the different software. These help store digital images, they extend the PSD file format to a wider range. PSB stands for Photoshop Big - meaning a large scaled image. A PSB file is larger than the 2GB that a PSD file stores. PSB files also save the image with all corresponding save options within Photoshop available this helps allow it save a bigger file size than PSD. 

 

Leaflet suitable graphics:

Illustrator Jpeg 

JPEG images are best used for photographs and complex images e.g. leaflets etc. It uses a compression method which removes colours to reduce the file size so that they can be saved smaller and compressed.  If the file size compressed too much it loses quality within images on the leaflet. When saving the leaflet within illustrator it saves it as a JPEG file so that it can be viewed as an image. Another option available for a leaflet graphic is GIF as a GIF file is always used when saving text, this links with the JPEG format as that is available for images needed to be saved. It is used effectively for logos and graphs  which require limited colour : PNG file format. 

Unit 35: Task 2: M2

M2
In addition to demonstrating you must justify the choice of tools, file format, image resolution and colour depth used when creating the images. In other words reason why those specific items were used.

Tools- Adobe Illustrator and Photoshop
File Format- AI, EPS, PSD, JPEG, GIF and PSB
Image resolution- The fineness of the bitmap image created in Photoshop is determined by the number of pixels, the more pixels the better resolution. Number of pixels per inch.
Colour depth-  There are 256 tonal values available for image resolution. This is so they capture the colours intended from photographs etc.

Work with logo: The process
Draw shapes - Circles, Imported space ship image
Unites shapes - Group selective shapes or images together so that they can be altered at the same time.
Direct selection tool - Grouping them together in alignment to adjust, re-size and move the shapes.
Manipulate colours - Change the colours individually or group them together so they have the same colour and effect.
Add symbols - None were used but can be added.
Layer panel - Create various layers in order to apply new ideas and shapes.
Edit symbols -  Manipulate the symbol to the preference of the viewer, alterations so that there is improvement.
Apply effects - Apply any shading or 3D effects to add texture etc.
Add a drop shadow - This was used on lettering and images to make the texture and form appear more 3D.

Work with text: The process
Lock & add layers - Overlapping various different texts to add effect.
Add text + Style text- Insert text in any font, size and colour.
Insert within layers -  Inserting the font within the shapes.

All of the graphics produced have been either created in Photoshop or in Illustrator so that they can be the best they can possibly be for the customers value and preference. By saving these images as either GIF or JPEG it allows the image resolution and colour depth to be better and of great quality. These images/logos have more pixels so that they have a better resolution. Many various tools within the software used has allowed me to create the images required and have all been used for a purpose, either with experimentation to then create quality pieces for the customer and others viewing.
