EXIF Data (Image Reader)

Most image files and digital photographs contain EXIF data. These are information embedded onto image files. It's actually a stardard for storing information onto image files. EXIF data can contain anything ranging from the file creation date to any information added by users or software. It even contains information about the camera setting if it is a photograph taken from a digital camera.

Phil Harvey created a PERL library for reading and writing the EXIF data. It allows you to use any scripting language to access the EXIF data. I've developed a form that uses his EXIF Tool. You can use it to read the EXIF data on any image file. Just type in the URL of any image or upload the image file and it will display the EXIF data.


Shinyknights Web Blog (PHP)

PHP is probably one of the oldest and most widely used web scripting language around. Over the years, it has evolved so much. Instead of using wordpress, I created my own blog using PHP. It was mainly to learn more about the PHP programming language. It contains a login system, a shopping cart, a customer relationship management section and a photo gallery.

Depth of Field Calculator (Android App)

In photography, a thin depth of field lets you put focus on your subject while blurring out the background. It's a very useful tool for putting emphasis on your subjects, allowing you to create mesmerizing photographs. This app lets you input the focal length, f-stop (aperture) and distance, and it calculates your depth of field. Now you'll always have the right depth of field for every shot!
