Choosing the Right Camera that Suits Your Lifestyle

Are you looking for a compact digital camera? Try to have a glimpse of the Sony Cyber-shot DSC-T110 with my initial review.  This may not be available now in the market but it can be of good comparison.

I have chosen to buy this camera, first and foremost, because of its stylish slim and sleek appearance.  I was easily attracted with its design the moment I had a glimpse of it.  It is available in two attractive colors, gray and red rouge.  But let us dissect the other features if it suits your taste.

First, one good thing about this camera is its 3.0" wide screen touch panel LCD.  You can review your shots in vivid colors and ultra-sharp contrast.  No more worry about tiny buttons.  Just tap the screen to review shots and select functions.



In the world of photography, everything circles around the lens.  This camera has a 16.1 megapixel lens for capturing finer details.  It sports a Carl Zeiss Vario Tessar 4x Optical Zoom lens.

The camera also has a Sweep Panorama Mode, to let you capture breathtaking shots of expansive landscapes.  Just press the shutter and shoot the scene with a continuous sweeping motion and the camera does the rest.

Here are samples of panoramic shots I took in El Nido, Palawan, Philippines.



If you want to take photograph immediately and do not bother to select the right mode, the Intelligent Auto Mode (iAuto) automatically adjusts the settings for you.  This camera has a smarter auto mode giving clear image results, faces with natural skin tone and less blur.






Do you love YouTube videos? With this camera you can shoot movies in HD.  Your movies will look stunning to the 720p high-definition MPEG4 recording format.





Here are the other advance features of the camera.
  • Optical SteadyShot Image Stabilization
  • High Sensitivity Mode (ISO)
  • Intelligent Scene Recognition Mode (iSCN)
  • TransferJet Technology
  • Smile Shutter Technology
  • Face Detection Technology
  • Anti-blink Function
  • Creative Painting Tools
  • Soft Skin Mode
  • Motion Detection

Taking Photomicrographs Using My Sony Cyber-shot Digital Camera

If you want to take some photographs and videos of microscopic features you are examining under a microscope lens, a simple digital camera is all you need.  No need to have very expensive special equipment to capture beautiful images.

As a malaria microscopy validator I need to record still photos of my findings to be included in the report. I have done these simple steps and techniques in the validation of microscopy results from in vivo therapeutic studies of antimalarial drugs.

Below is the list of materials and equipment you will need:
  1. A compound microscope
  2. Digital Camera
  3. Specimen in a glass slide
  4. 2 stable chairs with backrest
In order to capture a clear photomicrograph shot, the position and level of your digicam must be stable. You can use two chairs with backrest in order for you to have a good control in positioning the digicam. Rest your hands on top of the backrest as seen in the figure below.




Once the specimen is in focus under the microscope, level your digicam lens to the light coming out from one of the eyepiece.  You must be aware of the microscope's eye point or point of focus so that it would be easier to get the distance the camera must be from the eyepiece.  You can check this out by holding a piece of blank paper above the eyepiece.  You will see a light or image projection on the paper.  Move the paper closer or farther from the eyepiece until it is in focus.  That distance is the microscope's eye point.

Once you see the light or image projection on the display or screen of the camera, lower the digicam slowly until reaching the focal point.  Be sure to keep the position of the image projection at the center of the display as you lower the camera. You will notice that the diameter of the image projection is increasing until the whole field of view is in focus.







From there use the zoom function of the camera until the image fills the entire camera's display.  Once adjusted, click the shutter slowly.  You can reduce blurring by setting the self-timer to [2sec] and turning off the flash.  Press the shutter button and hold the camera steadily.  It takes a little practice to hold the camera steady, so take enough shots to make sure you have good ones with the right lighting and focus.







There you have it.  You can now transfer the images into your computer and edit them to your desired appearance.
