Pixel Ֆ A pixel is the tiniest part or smallest discrete component of any digitized picture or image and all photos actually start with a pixel. Digital photographs are comprised of thousands or even millions of pixels, which are the photo’s building blocks.

Megapixel Ֆ One million pixels make up one megapixel. When photographers use the term or word megapixel, they are referring to a digital camera photo’s maximum resolution in millions of pixels. In other words, cameras with a four-megapixel range take photographs that have a four million pixel maximum. This means quality to the consumer because better quality photos have higher megapixel counts. Buy a digital camera with the highest megapixel range you can afford, trying to keep it in the three or above megapixel range, especially for people wanting to make photo prints.

Resolution Ֆ This refers to the total amount of pixels in a digital photo, with the better quality, sharper pictures having a higher resolution.

JPEG Ֆ Formulated by the Joint Photographic Experts Group, a JPEG is a compressing image standard or compression method. JPEGs along with GIFs are two of the principal graphic formats found on the web. The lossy compression method used by JPEGs, which is a lossy file format, sacrifices a little of the original image data each time you save an image. The 24-bit color image stored by JPEGs, which lets you save innumerable colors, is well suited for images and photos with fine grades of color and tone.

Aperture Ֆ The opening that lets the light travel to the sensor inside the interior of the digital cam is the aperture. When you take a picture, inside the lens is a round, small opening that alters the diameter, which controls and measures the total light hitting the sensor in the digital camera. It is the shutter speed and aperture combined that control how much light reaches the camera’s sensor. An aperture priority mode, found on some digital cameras, allows the photographer to adjust the aperture to suit their requirements.

Focal Length Ֆ Often overlooked in amateur photography, the term focal length refers to how much the camera lens is able to magnify a shot. Normally divided into two categories, the focal lengths are telephoto and wide-angle for narrow fields and spacious fields of view respectively.

Memory Ֆ In the digital camera, storage space capability that stores the pictures is the memory.

Knowing the common digital photography terms can help people understand cameras better so they can purchase one that meet their requirements. And, of course – before you purchase, test the digital camera out first!

While the wind howled and screeched I could calmly listen to the audio track for the ceremony without the slightest worry. The voice of the preacher came through my headphones crystal clearly, and the voices of the couple accepting their covenants was also free of any wind noise. My soundtrack recorded flawlessly under conditions that would’ve worried many videomakers. If uncle Joe had been recruited to video the wedding, you would’ve been able to remember every gust of wind but not a word of counsel from the preacher. With my twin wireless microphone set, nothing was lost or disturbed by the weather.

Wireless Microphones can be hidden.

By hiding the lavaliers inside the tuxedo of the groom with a mic clip on his tie and likewise for the preacher, neither the weather nor passing traffic could ruin the beautiful ceremony. These mics picked up all the sound very clearly and invisibly. The crowd only knew the wedding party was wearing mics because I asked everyone to turn off their cell phones during the ceremony. Not that such would actually interfere with the signal, but it sure is an irritating noise in the middle of something so important.

Configuring wireless mics to record on the same group but different channels is the secret to avoiding feedback during recording. They really are a must-have for any serious videographer who records natural voice at events. These little preparations are the critical difference that makes our industry worthwhile to our clients. No client of mine will ever again have to worry about microphones being visible or not working since both of the problems are fixed by my system. I don’t say this to brag, I say this to encourage other videographers to spring for the few hundred bucks that will take their audio recordings to a professional level overnight.

The ability to capture high quality audio in tight crunches is an essential skill as a professional multimedia producer. Regardless of whether the video is corporate, personal, or web oriented, bad sound will nauseate your audience. Do them a favor, and take a little extra time to get a high quality sound track.
