What About a Flash?
A good photographer should be able to know when to use a flash or when it is not suitable. Most cameras have a built-in flash, but these are often restricting and only light the objects close to you.
If you can afford to purchase a flashgun, they offer so many more features and allow you to reflect the light off other surfaces such as ceilings and walls to get more natural light on a subject, rather than “hard light” from a built-in flash.

Flash, a popular authoring software developed by Macromedia, is used to create vector graphics-based animation programs with full-screen navigation interfaces, graphic illustrations, and simple interactivity in an antialiased, resizable file format that is small enough to stream across a normal modem connection. The software is ubiquitous on the Web, both because of its speed (vector-based animations, which can adapt to different display sizes and resolutions, play as they download) and for the smooth way it renders graphics. Flash files, unlike animated but rasterized GIF and JPEG, are compact, efficient, and designed for optimized delivery.
Known as a do-it-yourself animation package, Flash 4 gives Web designers the ability to import artwork using whatever bitmap or illustration tool they prefer, and to create animation and special effects, and add sound and interactivity. The content is then saved as the file with a.SWF file name extension. (The letters SWF stand for ‘Shockwave Flash.’)
Web users with Intel Pentium or Power Macintosh processors can download Flash Player to view Flash content, which performs across multiple browsers and platforms. Flash is lauded for being one of the Web’s most accessible plug-in. According to an independent study cited by Macromedia, 89.9 percent of Web users already have Flash Player installed.
A flash drive is a device that can be used to save information on a tiny, flash memory chip. Users can read and save data on it. These storage devices have been designed to be smaller than a typical storage disk, with some being the size of a thumb. That is why some people know them as pen-drives, while others prefer to call them “thumb drives”. Whatever the name, they all share one important characteristic, they can be hooked up to any computer. Thanks to their universal serial bus (USB) port compatibility.
Here, we will go over the different types of USB flash drives. Please note that they can be categorized according to their uses, or physical characteristics. We attempt to find a balance between the two.
This is a normal USB storage device with a major twist in terms of the steps taken to protect your data. It is fortified with physical or logical security ways to ensure that the data is not compromised. An example is the flash drive from Crypt ex, which has a combination lock before you can access the USB disk embedded within. Others, like those from Iron Key, come with an internal mechanism like password protection and encryption for added security. All in all, these devices provide added security for the protection of all data. However, you will have permission to add or remove write protection to keep the flash drive more secure.
