I realize Photoshop is not full without Illustrator, so I take the initiative to learn Illustrator. And this is the result. A brand new logo for Persatuan Mahasiswa Buddha.
For those who are new in graphics, what is vector and what is bitmap?
Vector is a type of file in graphics design which instruct how the image should appear. If the instruction is to create a clear border, then it will create a clear border no matter how you enlarge or zoom in.
For example, this is the middle part of the logo, the border are clear without any blur part (or we call it anti-aliasing)
Bitmap is an array of information arranged in pixels. It goes pixel by pixel. If you enlarge it or zoom it to a significant size, you will see the pixel clearly.
Like in this picture, the bitmap file version was enlarged to 600% and you can see the pixels starting to appear.
Of course you may claim vector are better here but I would say both have their pros and cons.
Vector are more suitable for logos, vector art, and the likes while bitmap are suitable for photography, effects, and the likes. Besides, vector image could be enlarge to a big size to suite display such as bill boards, posters, etc where if bitmap image are enlarge, it will be blurred and lose the detail. Bitmap on the other hand, could support gradient, toning and artistic effects, while vector can't (but it is possible to do gradient with Illustrator).
And you may change from vector to bitmap and vice-versa. From vector to bitmap, we raster it. Just open the Illustrator file in Photoshop and it will automatically raster for you. It would be rather tricky to convert from bitmap to vector. But with Illustrator CS2, you can use the Live Trace function which trace the bitmap into vector in instant.
Just some basic general knowledge in graphics from me. Thank for staying tuned here. Need to get back to the board for more Illustrator exploration.
