Graphics Article & Bitmaps
Vectors and Bitmaps Images (Magazine)
In
this article I will be explaining and covering certain topics such as; Bitmaps,
Vectors, Formats, Editing programmes (Photoshop adobe & Illustrator adobe),
Graphic Designing and all you need to know about Graphics Design. I’m an
experienced Graphics Designer and I will be creating a beginner’s guide for
Graphics Design.
The first
thing you would need to know about graphics, are the two key software
programmes that are used in graphic design today. One of the in particular
software is ‘Adobe Photoshop’.
Adobe
Photoshop is used primarily for editing and improving digital photographs, by
alternating aspects of a photograph through redefining and correcting faults in
the specific image. Whether it be colour co-ordination, tones, manipulating
elements and removing them.
A specific
element of Photoshop would be the fact of the software programme using ‘Bitmap’
images. Bitmap images are 2D graphics, which consists of pixels that are built
up in the form of a grid. They are individual miniature dots that represent
certain colours.
Each pixel
can represent more than 16 million different colours that can be displayed through
most computer monitors.
A Bitmap
image is the most appropriate format for photo-realistic images or such as
images with high amounts of decent quality detail, because of it being
contained with minor pixels.
Using
Photoshop can be quite competitive to get the gist of it, but once you know the
key elements of the specific software. You’ll be able to develop your abilities
towards being a qualified graphics designer.
The key
elements to having an understanding towards designing material would be having
the knowledge and understanding of the individual tools.
For example,
through the development of my poster I had recently created for a feature film.
I had used the basic tools from the tool bar to establish this specific
Poster. The
tools I had used were: Magnetic Lasso tool, Magic Wand tool, Horizontal type
tool and implementation of Layers.
The Magnetic Lasso tool is used to cut out
certain aspects of an image, to implement objects into your own project.
When using the Magnetic Lasso tool, the tool
automatically outlines and connects with the exact object your wanting to cut
out.
The Horizontal tool is text based to which
is the use of implementing text into your image, that can be optimized. You can
use a various amount of customizable effects from; Drop shadows, Colour
Overlay, Texture and etc.
Layers are one of the most important
features within using the software of Adobe Photoshop. Layers within an image
are a main priority because of its use of enabling a compatible editing system.
You can select individual layers that can
hold key elements of your image, whether it is the background, text and objects
that you have individually cut out using the Magnetic Tool. With the use of
layers you can also merge certain layers together with the Merge tool, in order
to create a more organised editing process and a sufficient product.
Vector
Vector images
are much different than Bitmaps. Rather than having to be built up of pixels,
vector image is made up of numerous lines and shapes.
These have
the term of ‘objects’, which are defined mathematically as a set of algorithms
or formulas. This allows them to be redrawn over and over.
However the
bitmap is static, as for vector is image dynamic. The vector image is not
limited by size or shape. The image can be easily minimized or expanded,
compressed or widened.
Bitmap
Bitmap
images are made up of pixels with in a grid. Pixels are elements that build up a
picture, which is displayed on your screen. They
are individual miniature dots that represent a certain color.
Each pixel can represent any one of the more than 16 million different
colors that can be displayed by most computer monitors; the bitmap image is
able to imitate the subtle color differences of a photograph.
The
second key editing software that you would need to about is Adobe illustrator.
This in particular software is used for developing font’s and logos.
Adobe
illustrator doesn’t use the same format as Adobe Photoshop; instead this specific
software uses Vector’s.
However
you can still combine both of the software’s, to development of a certain
product.
Through
the progress of an individual product you can implement a logo or font from
illustrator to Photoshop with the use of formats.
One
in particular format that allows you to transfer a vector image into a bitmap
image is EPS (Encapsulated PostScript). An EPS image is able to contain text as
well as graphics.
The
specific format that is used to upload or send images across platforms is the
JPEG. The JPEG is an image that has
been compressed within its quality; the quality of the image is lowered down so
that it is capable to be sent across different platforms.
The
next on the list is the RAW file format. The RAW file format is the high
quality image that cannot be transferred through platforms because of its file
size is to big and is unable to send or upload. The RAW image file must only be
processed through formats to become of use. The file is regularly processed
through (JPG etc).
