In this modern age technology is way more advanced than we could imagine in the beginning of 19th century. One technology is somehow connected with other one, if one technology rises second one will follow it. Lets take cell phones for example. First of all, we couldn’t imagine different communication than sending letters via post or messengers and talking to somebody for a big distance was just fantasy. But fantasy came true and now we can talk to anybody and don’t have to be wired to any machine or position. Just thanks to cell phones.
There are a lot more things you can do with it. Like browsing the web, checking e-mail, messing Facebook accounts etc. but some phones with operation system can be used also for photography purposes. Few days ago I bought Samsung Galaxy Gio running Android 2.2. And one of the first apps I got was Photo Tools. The app is totally free and great. You can use it to calc your exposure, flash output, hyperfocal distance and so on just using your phone! You can imput what lens on what body you’ll be using to shoot and it will take care of the rest. Pretty cool.
Of course, you can use build-in light meter in camera to determine correct exposure, but do you know when will golden hour start? What weather you might run into? These are just few of many useful functions of this app. And BTW having a grey card in your phone really rocks! 😀
You can download the app via Android Market 😉
