I was surprised to see that there’s not a great deal of info on the web on how to do a proper daily report – one that doesn’t have any gaps when data is missing. In this post I’ll try to quide you through building such a report using MySQL and PHP for a nice chart.
In this tutorial I will teach you how to edit in photo in Lightroom and Photoshop to dramatically alter its appearance and mood. We’ll change a broad daylight scene into a night-time one, lit by a street lamp. I’ll also take the opportunity to describe some non-destructive editing techniques in Photoshop.
Just in case you’re unfamiliar with the therm, HDRI stands for High Dynamic Range Imaging. As I’ve discussed before, a regular photo can’t capture the full range of lights and shadows that the human eye can see. Photographers have long learned to avoid high-contrast situations or to use them to create artistic effects. It all changed when Paul Devebec presented at SIGGRAPH 1997 a method for combining several images with different exposures into one single image with a much higher range of luminosity. To put things in perspective, a camera sensor can cope with contrast ranges on the order of 4000:1, while a scene of a room with an outside view in full sun (something our eyes see every day) has a dynamic range of 100,000:1.
Finding tools or remembering where is a button you need fast can be disturbing sometimes so I have selected 50 useful keyboard shortcuts to help you work faster.
If you own a semi-pro or pro digital camera and you’ve seen file quality settings such as “Extra fine”, “Fine”, “Standard”, “RAW” but never know what “RAW” stands for; if you heard about RAW on forums but never quite understood it; if you ever looked in awe at photos wondering how you could achieve such great colors, then look no further, as I am going to explain all there is to know about RAW.
I find it very annoying when I come across web apps that still can’t handle non-ASCII characters correctly. In this article, I’ll show you how, with just a few lines of code, you can “globalize” your online app.
To aid those who want to be in control of their cameras, to go beyond point-and-shoot, I decided to write a series of tutorials on the basics of photography. If you don’t know what the exposure or aperture are, this little tutorial is for you, so read on.
