 So, this actually is the third largest particular area in the design what we do for all our work. So, color is the most important thing then we have the design principles and all these design principles finally had to has to come to the fonts because you cannot write anything without the font. So, typically we use this word called font because in computers it is called font, but the original word for that was type which is still used and that is why we call it typography where it is the art of using the different type faces for communicating the message. So, application for us in our area is for the titling purpose whatever titles we create. So, like the formal definition of typography is actually to compose text to create readable coherent and visually satisfying information visually satisfying information is a very important term here. So, if you see something like right now what you see here if it is not clear then if I if I just select this and probably make it. So, the readability is considerably different now. So, that is what I was meaning by while I was saying that we will have at least 60 percent contrast between the two. So, if you do not have that then you land up into troubles. So, for example, if this is if I make it black again and then here I make a background also I just make it. So, now readability again is the issue right. So, even if I have two different colors for that. So, this was one of the things we thought of having a look at, but here is a some couple of examples which will illustrate use of fonts in a different way. So, I has everybody understood the color part and the graphic design part. So, we will move on to fonts now right fine. So, in using fonts there can be a very it is a very narrow line there that what fonts you use for what purpose and most of the time the purpose is defeated if you use a wrong font. I have some very vague examples right now actually not concerned with what we are all are doing, but let me I just thought we will use some of them for our interesting. So, here is a military recruitment poster that military wants to invite you to join the army. So, if it is written in this font or in this font. So, what makes sense more for the army right. So, it is very clear that army is not about floral patterns and very thin calligraphic stokes and all that. So, it is about robust way of nature it is completely a different lifestyle. So, you can you can imagine the lifestyle using this right you can see the difference here. So, that was one thing now immediately if I change the subject like it is a marriage invitation. So, if you like that font which was used for army if I use the same thing for marriage invitation now it does not make sense anymore right, but this makes sense here. So, all the floral things and the very thick and thin calligraphic ways it makes sense here. Similarly, let us come back to something which is nearer to our topics right. So, these are very extreme cases what I took, but I will come to very somewhat we nearer to our areas. So, this is the admission notice of some college they have a post got doctoral degree in microbiology. So, it is a poster for that. So, we have a postdoctoral degree it is written in this format right now and it is also written in this format. Now, what will make more sense the one on the top or the bottom one on the bottom how many people for top how many bottom why. So, people who say bottom have what is wrong with the top one anything especially wrong with the top one which you do not like what is that you do not like it is too much bold one thing second one by one anything else somebody postdoctoral degree it is looking but its type phase it is not looking that it is a very formal college it is looking very freak out. So, fun the part we will just go into some detail of what is this typography word all about. So, we have different font families. So, they can be categorized into some serif fonts and sans serif fonts primarily these are the two main fonts. So, some are serif and some are sans serif. So, you have list of some popular fonts in serif and sans serif. So, century calcine garamon times palatino the list is very long. And in sans serif you have another range of fonts aerial is also one of them but I have not mentioned it here. Apart from these two there are different fonts like calligraphic fonts which is which look almost like handwritten fonts. There are some technical or science fiction based fonts which are which look like futuristic. So, they are slightly different. So, just there is a digital. So, that then there are cartoon fonts there are some gothic fonts which were used in the very early ages. So, what is the basic difference between the serif and the sans serif? Now, this is where it starts getting tricky. So, particularly the serif fonts have uneven thickness of the strokes used in the character. So, for example, A has these strokes. So, you can see that this particular thing is thinner than this and that is why you can easily make out diseases serif font. And the serif word is actually this particular thing. This is called the serif where the baseline whenever it touches the baseline it has a curve here. So, this is called serif. On the other side sans serif will have all even thickness everywhere. If not even at least it will be very very minimally different than each other. There would not be a much of a contrast in the thicknesses. So, now how do we have application of these fonts in our e-learning domain? So, what are the things which will have some bearing on this thing? So, one important thing is about the information graphics that we create. So, information graphics in e-learning are typically the main title or the opening titles what we say. Then we have the name of the speaker or the presenter. We have the end titles and we sometimes have other graphics like we have the slides in between or whatever. Now, the main opening titles also is the subject of very deep interest to be taken on. We normally just do it in a very haphazard way, but if we really concentrate then there are lots of things to be done even in the main title. So, the opening title should typically consist of the following things. It will have a subject area definitely defined. It will have the lecture title of the person who is going to talk what is the subject of that. Subject area is meaning the main subject like it can be a biology or a mathematics or whatever or then it can be the specific lecture. Third thing would be the speaker name that there can be some numerical data like what is the lecture number, what is the course number or what is the date if it is required and there can be some organizational affiliations like if you have a logo of your organization or you may have something written like IIT Bombay or YCMOU or whatever. Now, based on that we will have an assignment of creating something like this. What I want is you all have to split in the groups of two now. So, there will be 16 groups of two each and what I will have a list of so this is a typical example right I have given here is about a subject area which will have a lecture title it will have a professor which will have the lecture number, the date and the affiliation right. So, now I have three main assignments to do. So, one thing is about color scheme. So, basically the here I have written 16 different subjects right so each one pick one, but everybody has to do the other one also. So, two people in a group so they make two color schemes for this now the point is that we will have color schemes based on some why I have deliberately not spoken about color scheme for a subject. What I have now shown is a very very broad view of what is the color scheme, how color scheme can be designed. Now, I have not deliberately shown that for marine engineering this can be a color scheme I want you guys to explore that now so how can you have different color schemes. So, these are the subjects now I want actually five shades, but five shades is too much I want five colors to be chosen for each subject. So, if you say marine engineering then you will have five subjects five shades. Now, remember the shades what you choose have to be finally used in making a title or making a title of the person which which comes as a roll over title when the speech is going on. So, these will be the applications of that these are not the photographs to be taken. So, you have to remember that five shades if you choose, you have to use five shades of any one of this two of the subject. Then you have to also choose a font for any two of this. So, marine engineering can make font or national school of blind can make font use. And the third one is about make one slide using the design color and the typographic principle what you have seen now for the two subjects what you have chosen. So, that is why in my case if I pair up with someone then suppose I have used marine engineering then I have chosen five colors for marine engineering and I have chose the font for marine engineering and I have chosen font and colors. Using both these I can make a slide of marine engineering. The opening slide which I have told you this can be done with all these things. And for the reference I have a site called thefont.com so, if I choose the font So you can use this site called dafont.com which is a very good collection of fonts. Most of the fonts also again it is a very interesting piece of information for all of you. Most of us do not know that fonts is a copyright thing. So today I create a font, it is my copyright and I am supposed to be paid for my font being used by someone else that is a typical thing. So especially on this site you will see that these fonts if it is free then it is written here that it is free for personal use and so and so forth and you have to download the font for PC, Macintosh or whatever way right. But there are some fonts which cannot be used by anybody for any other purpose it is a paid font. So in that case they have written it there that it is not a free font it is a paid font. Anyway for our purpose we do not have to worry about these issues we are just doing it for our educational purpose so does not matter. I just thought another information I will share with you all. So there are so suppose this is completely free so whatever use you want to use. So this is these are the different, this is not free now. So it is saying that there are some comments here and you can download it but it is not free in case you want to use some commercially then you have to maybe take permissions of people and other things. So when you download you will get those permission letters. But this website is quite good in fact they have already organized the fonts in different ways so it is a very very good site to have as a reference also for all of you. So I think I am clear.
