Basic photography: understanding histograms
Every DSLR has a display feature called histograms. It looks like a graph with random data that any new photographer don’t know what it actually is. And maybe, won’t even care. Here’s a peek, it’s a reader that records how much light (how bright or dark) a picture is .
You should know that every LCD screen – camera, TV, or digital frame – could display different brightness level of a particular picture. What you see bright in this screen might not the the same in that screen.
This is why histogram comes in. It is the standard reader to record how bright a pic. A sample, you had an underexposed pic. So this should looks quite dark as shown in histogram. Now in your camera, it looks dark as expected, but it is quite bright in your computer screen. Chances are, your computer screen are set a little brighter than normal.

Windows 7: Still Vulnerable to Viruses
Windows 7 is a valuable upgrade delivering an awesome new user interface, but don’t expect any major improvements in security.
Anti-virus software vendor Sophos tested Windows 7’s built-in anti-virus capabilities by feeding a clean system 10 pieces of the newest malware. Eight out of the 10 samples ran successfully, claims Sophos.
“Unfortunately, despite Microsoft’s claims, Windows 7 disappointed just like earlier versions of Windows,” says Chester Wisniewski, a senior security advisor at Sophos, in a blog post. “The good news is that, of the freshest 10 samples that arrived, 2 would not operate correctly under Windows 7.”
Sophos’ findings aren’t surprising: Windows 7 promises backward compatibility with most software that works on older operating systems, such as Windows XP. It would be reasonable to infer most malware compatible with Windows XP or Windows Vista is likely going to harm Windows 7.
