2 Types of software used for maniplulating digital images

Adobe Photoshop

Adobe photoshop is an image editing software developed and manufactured by adobe systems.  The photoshop software allows users to manipulate, crop, resize, and correct colour in any digital image.  Photoshop software is used by all types of audiences from photographers to web site designers.

The basic tools used in photoshop are:


Rectangular Marquee Tool (M)

This tool is used to make selections on your image, in a rectangle shape.  It is used to change the area in which your image is affected by other tools or actions to be within the defined shape.

Move Tool (V)

You use this tool mostly to move things.  It is used to move a layer around after it has just been placed.

Magic Wand Tool (W)

Yous use the magic wand to select a colour rang.  It will select a colour or transparency based on the area in which you click.

Crop Tool (C)

The crop tool is similar to the Rectangle Marquee Tool, it crops your image to the size of the box, any information or any areas that was outside of the box is now gone, but you are still able to undo your actions and retrieve it again.

Slice Tool (K)

This tool is mostly for the creation of websites, or splitting one image into smaller images when saving out.

The disadvantage of photoshop is that it is cost effective and it is difficult to learn how to use, for people who are just starting off you would need a manual or a guidance tutorial to explain all the different tools.  Photoshop has a lot of different tools and each with diffeent functions, so for a beginner user or someone who has used it before may need patience and may take time teaching themselves how to use them correctly.  Photoshop is also a big application, so therefore it can take up a lot of memory on your computer.




Sumo Paint

Sumo paint is a free online image editor which was created in 2007.  Sumo paint is similar to Adobe Photoshop in that it has similar tools to edit and re shape/resize a digital image.  Sumo paint is used more for illustrating images.  For example you are able to attach a glow or colourful background to an image or give it a reflection and a different shape.

The different tools used in sumo paint are:


Brush Tool

The brush tool overall is the most important tool in sumo paint.  It is preselected everytime the user launches sumo paint.

Symmetry Tool

With the symmetry tool and its multiple properties, you are able to create very different symmetrical creations.  You can experiment with the symmetry points, gravity and modes to get the exact result you want.

Eraser Tool

Eraser Tool is the anti-brush, it removes any mistake made or can be used to improve on the design of your image, it is also able to be adjusted to any size.

Ink Tool

The ink tool is used mainly for creating realistic ink impressions.  You are able to adjust the ink wetness with mode value slider.  The ink mode can be applied to te brush, ink, pen, symmetry and also all of the shape tools.

Blur/Smudge Tool

This tools has a variety of brushes and a possibility to use the following blending modes: normal, lighten and darken.  The finger paint mode paints with selected colour but also creates the effect.


The disadvantage of using sumo paint is that you have to search through various number of tabs to be able to find the exact tool you are looking for.  A lot of the names used for the tabs are terms that a lot of people may find difficult to understand.






The difference between Adobe photoshop and Sumo paint

The difference between Adobe photoshop and Sumo paint is that photoshop is a software that is used to correct the colour, red eye or even the shape of a photo.  Whereas sumo paint is slightly different, yes it is able to do almost all the same things as Adobe photo shop  only difference is that sumo paint is an illustration software, it is used in all the same ways as photoshop but it is also used to edit a image further, for example reshaping and adding a glow and different layers and also changing the colour sequence in an image.  Also photoshop is designed to have all the different tools along side the picture so that you do not have to go searching for them, whereas sumo paint has the tools in different tabs and may be difficult to find the right one.
