Lecture 3

Guess I had done my blogging late. But nonetheless, it will still be good to start than not starting at all.


Lecture 3 today was a bit more technical that usual, guess most people from non-technical areas may not be able to understand them quickly. In my own opinion, some knowledge on these technical stuff is critical and absolutely essential.


Drawing a image, say on Abobe Photoshop, you will require to understand several things when creating a new image, namely the resolution, colour and image size.


Resolution is an important part of the image as it tells the programme how much information you want your image to contain. Like 72pixel/inch (ppi), which means that in per square inch, there will be 72 * 72 pixels in that square. That means, your image will be clearer and sharper when compared to one that has lower resolution for example an image with resolution 48ppi.


Once you had determined your resolution, the next is the colour space. RGB, CMYK are common colour spaces found on most image editing or creation programme. RGB are common for graphics created to be displayed for screen viewing, but for publishing, you will need to convert it to a CMYK colour space.


Image size is also important. Should you create a poster for printing in A3 or A2 size, you may need to create a blank image size based on a A3 or A2 size before proceeding in creating the images on the file, especially they are of raster type. For vector-based images, they do not have this problem, but you will not be able to create high quality images on vector based drawing (unless you are expert in Geometric Math and Linear Algebra).
