Aside from sharing my experiences and my thoughts as a videographer and a business man through this site, I also wanted to share my knowledge and learning about my craft to the people who takes time to read my blogs so they can also learn something from here.
So now, I thought of camera lens, the most important part of the camera. Whether it’s a manual, digital camera or video camera, it will be worthless without its lens.
I am not to go into very technical details but just something we can understand and easily remember since cameras are now part of our everyday lives.
Camera Lens - a lens that focuses the image in a camera
Taking pictures has not been as convenient practical and easy since it was built-in our mobile phones, almost all models of mobile phones have a built-in camera now, started from VGA to almost 5 mega pixels in resolution. Let us then see the difference of the 2:
VGA vs. PIXELVideo Graphics Array (VGA) – 640 x 480 resolutions, basic and primary level of camera specially in mobile phones.
PIXEL – the smallest piece of information in an image. Pixels are normally arranged in a regular 2-dimensional grid and are often represented using dots or squares.
Another common feature that we should look for in choosing the right camera is the optical and digital zoom.
OPTICAL vs DIGITAL ZOOMOptical zoom uses the optics (lens) of the camera to bring the subject closer.
Digital zoom is an invention of digital video cameras. It is not uncommon to see digital video cams with 300x digital zoom.
For our purpose, digital zoom is not really zoom, in the strictest definition of the term. What digital zoom does is enlarge a portion of the image, thus 'simulating' optical zoom. In other words, the camera crops a portion of the image and then enlarges it back to size. In so doing, you lose image quality. If you've been regularly using digital zoom and wondered why your pictures did not look that great, now you know.
When it comes to using zoom? Here it is: Always use optical zoom. When buying a camera, choose one that warns you that you are about to use digital zoom or that allows you to disable digital zoom (most do). If you do use digital zoom, use it only if it does not appreciably impact your image quality. If you rarely print past 4x6 in. photos, digital zoom may not adversely affect you.
When comparing cameras, you should always use optical zoom. There is no point in comparing digital zoom with digital zoom or optical zoom with total zoom. Always compare optical zoom with optical zoom.

These are just basic details about camera lenses but are indeed important to ensure that picture perfect smile.
