GIMP

Image
 Hello, hello fellas! It sure has been a while, hasn't it? Today I'm bringing you some new stuff that you may find interesting. As a lot of you may know, there is an endless amount of photo editing programs like Photoshop, Krita, A.Illustrator... you name it. However, a lot of people tend to miss one of the most useful ones out there, GIMP! In this post I'll show you the basics of what you can do in this program, but don't forget to check the blog these following days to learn even more. For this first project, in order to show you what you can do, we will grab an image from the internet (possibly one that is slightly tilted). And we will try to make some changes. Note that this doesn't imply the picture itself needs to be fixed or anything like that, we will only do this changes to see the functions of GIMP and nothing else. In this case, I will be using this beautiful landscape taken by the photographer Oleksandr Ryzhkov! (You can see his work here ) As you can se...

VECTOR IMAGES EXAMPLES

 Hi guys! As you may all know, on a previous post I talked about vector images and raster images. So, if you all remember correctly, vector images don't have pixels, rather, they use mathematical equations to represent images. In this post, I will show you a couple of examples of vector images I have created using the program inkscape . The Swedish flag, the EU flag and Thailand's flag. So, if you want to know how to create images like these, tune in this next couple of days to find out!

DIGITAL IMAGES QUESTIONS

Let's say, for example.... Think you want to print out a photograph with a size of DIN A4: 210 × 297 mm maintaining a printing quality of 200 dpi. Which resolution would the image need? So, we want to print out an image of 210 x 297 mm, knowing that 1 inch=25.4mm we can start calculating our results.  >210:25.4= 8.27 (approximately) >297:25.4=11.7 (approximately) And now, we multiply it by the dpi we want. >8.27x200=1660 >11.7x200=2340 And there we have it, we would need an image with a resolution of 1660x2340 pixels. However, I know some of you still have questions like: Which resolution would the same picture need to have a 300 dpi picture? Well, it would be very simple. Knowing our image is 8.27x11.7 inches, we just have to multiply these numbers by 300 dpi instead of 200. >8.27x300=2480 >11.7x300=3510 So, for 300 dpi, our resolution should be 2480x3510. I believe both of those questions sum up everything pretty nicely, but if you still have doubts, then don...

DIGITAL IMAGES

Hey there once again guys! Today I was feeling a bit on the informative, so I decided to enlighten you all with some information about digital images.  We see digital images all the time. In our phone, in our computer....anywhere. But, even if we do see it on a daily basis, do we really know what it is and how it works? To start off, we have two types of digital images, vector graphics and raster graphics. Vector graphics use geometrical primitives like lines, shapes or polygons. Made out of mathematical equations that result on an image. The good thing about this type of images sis that it isn't made of pixels, so it cannot loose its quality if you make it bigger or smaller. Raster images, on the other hand, are made of a grid of pixels or points of color, and they can be stored as different format files. However, unlike vector graphics, its features and quality depend on a series of factors. For a better understanding of what I am about to tell you, you can take a look to the cha...

DIGITAL SECURITY

 Hey, hey, hey security maniacs! I know the internet is a very touchy subject, and so is the security we have while we are online. A lot of people don't like talking about it, and to be honest I don't blame them. However, since most people don't like getting very detailed about the way they surf the web. I will post a couple of posts in order to teach all of you some basic rules about digital security. You will find these posts below this one.  Also , I was planning on doing a quick voting session in order to see which tips you liked the most out of these posts (phishing links and password security). You can vote here ! All the answers will be published in this post for everyone to see, so everyone can see the feedback. But remember, if you don't want to vote, that's completely okay! :D Here are my the posts about digital security if you guys haven't seen them, or if you want a faster way to get to them! Phishing Links Password Security

PASSWORD SECURITY

''I always use the same password for all my accounts and applications. I do not like to use complicated passwords because it is difficult to remember and too long. What do you think?....'' Bceuase of this, let's say, for example, you're in your home using your computer and all of a sudden a hacker gets a hold of your password for a certain website. Since it is only one website it should be okay right? WRONG. Most people use the same password for a wide number of websites. Therefore, in this post, I will be giving some tips in order to avoid this for those who don't like complicating your passwords. Or, for those who didn't know they were doing it and want to start preventing a future attack. 1-So, the first step to make our password more secure is, of course, to check the number of characters it has. For example, if we have a 6 letter password like ''Tomato'' then it would be advised to get a longer password of at least 8 characters or mo...

PHISHING LINKS

Image
''I have recently received emails and instant messages that look legitimate at first glance. These messages come with URLs that prompt you to input your personal information. In turn, I think It will steal my credentials and use them to access my accounts and personal data.'' Imagine this, you're in your house watching a movie, when all of a sudden you get an unknown email from a website you visit frequently. The email looks legitimate, but once you enter the website it tells you to enter your personal information, which makes it seem a little bit off. Well, don't rush and enter your information without reading this post, because this, like the example at the top of this post, might be a case of Phishing Links . Everyone gets an unknown email every once in a while. Or an email that looks legitimate and ends up being the other way around. While opening emails is completely fine and won't cause trouble, clicking the links from said emails can end up badly if y...
