Photoshop’s Beginnings

spash page for PSThere was a time when Photoshop (PS) was a fresh new product that nearly nobody had heard of. Of course those times are long gone, in fact I think that if you were to ask anyone on the street, in any country in the world, “What is Photoshop?,” all would give you basically the same answer, “It is an image editing software.” If there were any variations in responses my guess is that it would be minimal. It’s remarkable that PS has basically become a worldwide household name, (assuming I’m correct of course), you could include it with such brand names like Coca-cola, Toyota, and maybe a few others.

So how did PS get to be one of the most well known products in the world? Who created it and when? The beginning of every computer graphics course as I’m introducing PS to my students, I usually spend some time going over how PS got started, and most of the times the students seem somewhat surprised by its meager beginnings. They rarely know that PS was not created by Adobe and that the software was given away when you Continue reading

Why you can’t increase the resolution of an image

low resolution imageOne of the core understandings in computer graphics is that if you want a high resolution image, you must start with a high resolution image. Forget all the tv shows that you’ve seen where the person is standing behind a computer technician asking them, “Can you sharpen the image a little more?” The computer technician  maybe clicks a few buttons and the suddenly the license plate that was too blurry to read becomes crystal clear. It’s a miracle, the computer can do anything! Sorry, that isn’t real life, at least with current technology. A computer can do a lot of things, but when it comes to enhancing low resolution imagery the computer at best must ‘guess’ what the image is.

To understand this concept it helps if you understand the way an image is formed on the computer. If you were to zoom in as far as you could on any image, you would see a collection of different colored squares, these squares are called pixels. To a computer, that image isn’t a photo of anything, it is just as I said, a series of pixels placed in a particular way that when viewed by humans looks like you, your dog, Continue reading

All this talk about wireframing…

wire framing imageSo lately I’ve been trying to get into wireframing as the first step in the process of creating an web site. I’ve gone into detail about why I think it’s important in a few articles. If you’re interested in the subject I suggest that you search for wireframing. The main idea is to remove some of the waste of designing a site with expected elements. The truth is, is that many times you don’t know what those elements are going to be, so jumping into Illustrator or Photoshop to layout your design can waste a lot of time.

I just read an article, “12 Practical Tips for Creating Better Wireframes” that seemed to Continue reading

Print or Digital, what others think

ad for paper designAs I get older I start to miss somethings that I took for granted a long time ago. Like getting the latest magazine as soon as it came out. Sometimes it was even  an event that warranted a cup of coffee and a quiet space for the next hour or two. Now though I get so much info fed to me through various web sites and apps that I don’t think I have sat somewhere in years and just read a magazine, digital or otherwise.

That’s what drew me to this survey in the first place. The poll questioned people about their perceptions between digital and print. The survey was commissioned by a company with a stake in printing, so I’m not sure if the survey was slanted their way. However, if you’re like me you’ll probably find the data interesting.

The following is a direct copy/paste from their pdf. You can find it here(I did the graphs myself though) Continue reading

Hosting 101

hosting illustrationI recently wrote and submitted to this site a short, but in my opinion concise article about picking a domain name. I tried my best to include all the ins and outs of the requirements and not so important details. Now I would like to discuss the good and bad of the hosting world.

To start with, let’s make sure that we’re discussing the same thing. A host is a company who controls a computer that stores your information. When someone visits your domain, the computer serves your web site to their browser.  The host is the company, the server is the computer. That distinction is important when choosing a place to serve your site.You may have a great host, but a poor server, or reverse that. Maybe the server is strong, but the host has awful client support. When shopping around you need to consider both aspects.

Okay, that’s really over simplified, but if you think Continue reading
