Illustrator file type – .AI
Pixel based program – Photoshop (is resolution dependent, which means it has to have the resolution to have a good image)
Vector based program – Illustrator (isn’t resolution dependent)
Photoshop resolution is measured in DPI (Dots Per Inch)
A4 page has a resolution of 300 dpi
Web page has a resolution of 72 dpi
Alpha channel = Transparency of a picture (like .png)
PNG format is a lossless compression file format, which makes it a common choice for use on the Web. PNG is a good choice for storing line drawings, text, and iconic graphics at a small file size. JPG format is a lossy compressed file format. This makes it useful for storing photographs at a smaller size than a BMP
Scalable Vector Graphics – SVG
Illustrator gives you CMYK, Photoshop gives you RGB
On Illustrator you have much more control over the way a piece of text appears unlike on photoshop. You can change both the type and font. The biggest difference is that you can create a shape using the shape tool or the anchor tool and put the text around it by simply clicking the text tool onto the line. To put the text in a curve, as seen above, you just have it follow the line of a path tool.
The second image shows what you can do to a letter once you have expanded it, this is done by simply clicking the expand button under the object heading, you’ll then have anchors on te corners of the shape you can pull and push as you like.
I recreated the olympic logos on Illustrator using the anchor tool and then colouring them using the eye dropper tool for the most accurate colours. On the Rio logo I added a gradient effect, much like the original had by using the gradient tool.
When we were set the task to create a shopping basket I used the rectangle shape tool and moved the top two anchors so that the lines would be in a slant.
I then created a line of circles, I held down shift as I did this so that the shapes would be perfect circles.
These three flags were made on Illustrator using the rectangle shape tools for the Greece and
the Gambia flag and the Curvature tool for the South Africa, as Illustrator doesn’t offer the shapes needed to create it.
The rectangle shape allowed for accurate and neat looking shapes to be created with ease, however the curvature tool was very high maintenance, at least, for someone who is new to Illustrator, whenever I clicked on the created outline from the curvature to grab at an anchor, I would usually make a new anchor by mistake, which subsequently lead to more adjustments to the shape being made as I couldn’t create accurately straight lines with as many anchors as I had.
I evaluation of my work, I believe that the Greece and Gambia flag came out well, the shapes were accurate and the lines were straight, however, the colours were off, I could have prevented this or improved these flags by using the Eyedropper tool.
The South Africa flag came out a lot worse though, the lines were not straight and the shapes were misshapen, but given that this is the first attempt at using Illustrator for something of that caliber, it shouldn’t be surprising that the flag came out wrong, to improve the flag I could use less anchors then I did so that it would be easier to create straight lines, I could have also simply used the rectangle tool and adjust the anchors.
Much like the other two flags, the South Africa flag had incorrect colours.
