Basics of Cameras and Exposures

January 1st, 2010

Over the past year, I’ve been spending a lot of time learning and experimenting with digital cameras. I got a Nikon Coolpix P80 last spring (you can read review of the Coolpix P80 on Associated Content), and I recently upgraded to the Canon t1i and purchased a variety of lenses to go along with it.

I wrote up a series of short articles on Associated Content explaining the basics of exposure. If you’re starting out with photography and feel that you’re ready to break out of the “auto” mode on your camera, they’re a good read. The more you read about photography and how everything works together to create an image, the better you’ll be.

What Does the Aperture Setting of a Camera Do? The aperture is the size of the hole that lets light into your camera. Bigger hole = more light, smaller hole = less light. But, this also affects the depth of field – how much of an image will be in focus. Read the article for more details.

What Does the Shutter Speed Setting of Your Camera Do? The shutter speed is how long light is allowed to shine on your cameras image sensor (or film, if you’ve got a film camera). Keeping the shutter open longer allows in more light, and keep it open for a shorter period of time allows in less light. But… this also affects whether your picture will be blurry or not. Read the article for more details.

What Does the ISO Setting On Your Digital Camera Do? The ISO rating determines how sensitive your camera’s image sensor is to the light coming in. Turn the rating up, and your sensor will be more sensitive and create a brighter image. But, this also creates more “noise” – little pixelly speckles that can ruin your photo.

Fixing Up an Old Dell Inspiron 2600 Laptop

December 5th, 2009

Recently, I had a couple Dell Inspiron laptops donated to me to refurbish and use in my classroom. One of the machines gave me no trouble, and within a couple hours I had a fresh install of Xubuntu on the machine and it was ready to go to school.

The Dell Inspiron 2600, on the other hand, was troublesome. I finally have it working now, and I’ve written a couple articles on my other blog about the process. These aren’t in depth tutorials, but they’re meant to help point people in the right direction if they have similar problems.

Installing Ubuntu on a Dell Inspiron 2600. This seemingly simple task was complicated by the fact that the integrated graphics card doesn’t seem to work with most Ubuntu installations. I found some suggestions that Ubuntu 8.04 worked, and eventually it did after I modified the settings and specified the correct graphics driver. Read more about this in the full article.

Adding RAM to a Dell Inspiron 2600. This should have been simple, but it wasn’t. The machine reported 320mb of installed RAM, but I could only find one memory module – a 256mb memory module located underneath the mother board. After skimming through the documentation a couple times, I found that there was a second location to install a memory module located on the other side of the motherboard (underneath the keyboard). I followed the Dell documentation to disassemble the laptop and install another 256mb chip (which replaced the presumably original 64mb RAM chip).

Recent Writing on Associated Content

November 22nd, 2009

Recently, I haven’t been doing a lot of work online. Real life is plenty of work.

I have been updating my other blog a bit, but its mostly inconsequential posts about my training as a runner.

I have, however, been doing some writing for Associated Content. I’ve amassed a decent amount of pageviews there (170k), and I’m close to hitting the second highest ranking on the site – Clout 9. If I keep writing articles, I’ll hit that benchmark in a month or two. The next goal would be to hit Clout 10, which would require 3-400k pageviews. These are fun goals, but they also bring with them higher pay-outs per pageview… so there’s a point.

Anyhow, here’s a quick rundown of some of the articles I’ve written recently.

Where Can I Find a Replacement Lens Cap for My Nikon Coolpix P80? I lost the lens cap for my P80, and I had a hell of a time finding a replacement. Nikon doesn’t seem to manufacture the part anymore, but I found a third party vendor on Ebay. Very useful article, if you happen to have the same model camera.

What is the Derivative of a Function? I’ve been working with some kids at school on Calculus, so I thought it would be interesting to try my hand at explaining math concepts online. I might expand this work into a larger site in the future, but for now I want to get some thoughts on paper, as it were.

How to Remove an Autorun Virus from Your Flash Drive. We had a nasty infection on our school network recently, and I spent a lot of time cleaning autorun viruses off my flash drive. I found a quicker way to handle it, through a basic DOS batch script, explained in the article.

Moving Elsewhere. Slowly

December 7th, 2008

If you take a look at the archives, you may notice that this site hasn’t been updated in quite some time. April, to be specific.

In the late Spring, I got burnt out and kind of lost momentum to continue posting things. Ironically, the site was increasing in traffic and readership. Doh.

I was otherwise occupied throughout the summer (Damn you, WoW!). When the school year swung around, and I officially quit WoW, I decided it was time to revive my old web development/publishing pursuits.

However, for a variety of reasons, I chose not to just pick up with this site and continue. For one thing, I wanted to combine a handful of projects into one, manageable project. One reason I stopped posting here was to work on a blog about World of Warcraft. My new project – This Life of Brian – incorporates a couple of different topics/websites under one umbrella. It makes it a lot easier to keep things up to date.

Also, I grew tired of this domain name. It sounded catchy at first, but now I think it’s a bit spammy. I had a couple articles do well on Digg, and some commenters pointed out the domain name. Doh.

I’m now in the process of slowly migrating the archives of this site to my new project. They’ll all be contained in the web development and publishing section of the site – Nerds at Work. It’s pretty well segregated from the other topics (online gaming, education, and random blogging pursuits). It’s got its own theme and its own RSS feed.

I’m also hosting all of my new content at that site, and this site will no longer be updated. I just renewed the domain for another year, so this site will be here until next December. However, don’t expect anything new here… and hopefully all of the old articles will be at Nerds at Work by the spring time.

So what are you waiting for? Head on over and check out my latest work.

Share Your Reading Habits: Google Reader

Helium – Writing for Profit and a Community

April 12th, 2008

This site has kind of strayed from my original intent – to explore and report on ways to make money online. For a couple months now, I’ve focused almost exclusively on the development and design end to working the web for cash.

I think it’s time to take a step back and look at a site where you can write for profit – without requiring any tech, design, or development savvy. I’ll be working on a complete section about Helium, but in the meantime here’s a quick overview.

Binary Code and Bitwise Operators (in PHP)

April 6th, 2008

At it’s core, all of the information on your computer is made up of bits – or 0’s and 1’s. There’s quite a bit of interpretation that goes on between that basic binary code and the information as it is displayed on your screen.

However, you may find a time to work with data at the binary level in PHP (and many other programming languages). Here’s a quick guide to understanding binary numbers and the common operators for handling them.

Google Analytics is a great tool for gathering data about your website. You can track and analyze all kinds of data about your visitors, their navigation paths, and the effectiveness of your content.

To use Google Analytics, you need to place some javascript on your website. A commonly asked question in forums is, “How do I add Google Analytics to my Wordpress template?”

Spread the Love: Intersite Linking

March 27th, 2008

I recently started working on a new website – the one I mentioned in the article on creating individual 301 redirects for Wordpress.

I got the site up and running, updated some content, and then submitted my sitemap information to the Google Webmaster Tools. As usual, the next step is to wait and see how long it takes Google to start regularly indexing the site.
