If you’ve spent most of your time behind the lens shooting JPEG files, the format most casual point-and-shoot cameras capture by default, making the leap to shooting in Camera RAW is a revelation.
The uncompressed RAW image format allows unrivaled control over your finished product. With RAW, you can effectively go back to the scene of the shoot and re-adjust the exposure, change the white balance, alter the contrast and make dozens of other tweaks that JPEG files don’t allow for.

Given the increased complexity of Camera RAW images, it’s not surprising that whole new crop of images editors have come around to help you deal with the workflow requirements.

It has much of the brawn and brains of Adobe’s flagship Photoshop app, but it’s been built to more specifically fulfill the unique demands of the Camera RAW workflow.

In the part one of our HTML 5 tutorial, we looked at some of the language’s new structural markup tags that are designed to reduce the “<div>-soup” of HTML 4 and add semantic meaning to your page’s layout.

This code was written based on a template by John Resig. The original can be found at John Resig’s addEvent function website.
Action is a Form attribute that communicates with the common gateway interface (CGI) program to process.
For example, if you entered “bananas” to the following form:
Please process this:
The HTML form would send the input “bananas” to the cgi script. To the cgi script, the action would look like: ../processor.cgi?food=bananas
Demographics are the DNA of marketing: age, sex, income, profession, marital status, location, and so on.
Advertisers rely on demographics to help decide which sites are most likely to help them reach their specific audience. Knowing your audience demographic not only helps you sell ads, it also lets you know who your users are and what they want.
