How To Use M Mode

Photography have three pillars  ISO, Shutter speed, Aperture  
It is difficult to take good pictures without having a solid understanding of ISO, Shutter speed and Aperture   – the Three Kings of Photography, also known as the “Exposure Triangle”
using an Auto mode puts limits on what you can achieve with your camera.

1) ISO- 
the level of sensitivity of your camera to available light. It is typically measured in numbers, a lower number representing lower sensitivity to available light, while higher numbers mean more sensitivity. More sensitivity comes at the cost though, as the ISO increases, so does the grain/noise in the images. Examples of ISO: 100, 200, 400, 800, 1600.

As you can see, at low ISO settings noise really isn't an issue,but as u increase iso number u get more noise
you should always try to stick to the base ISO to get the highest image quality

2)Shutter Speed
In photographyshutter speed is the length of time a camera's shutter is open when taking a photograph. Shutter speed is where the other side of the magic happens – it is responsible for creating dramatic effects by either freezing action or blurring motion.

A Fast Shutter Speed Can Freeze Action
A Slow Shutter Speed can Capture The Flow Of Motion 

                                               Freeze  The Action      shutter speed - 1/2000

Example of  Motion Blur          shutter speed - 15 sec

3)ApertureWithout a doubt, it is the most talked about subject, because Aperture either adds a dimension to a photograph by blurring the background, or magically brings everything in focus.
The Aperture Size determines how much light enters your lens. The size is controlled by an iris, like the human eye. Aperture sizes are measured in F-Stops; the higher the F-Stop number, the smaller the opening

Here are two examples of the same scene shot with two very different Aperture settings, to show the difference that Depth of Field can make. As you can see, a larger Aperture results in a shorter Depth of Field

In the above situation, the larger aperture (left image) is better because it blurs the background vegetation, which is a distraction from the main subject. Using Aperture Priority allows you to directly control how much of the background is in focus (Depth of Field).

Panasonic lumix dmc-lz20 review

guys i must say dis camera impressed me alot..
the camera it provides a platform btwn the simple point and shoot and dslr...

the zoom is excillent and the image does not shake even at 21x zoom thnx to O.I.S its the best in class i have even checked the sony dsch-100,nikon l810 but no one provides stability like dis...

moreover this cam provides u to set aperture and shutter speed iso etc manually if u dnt knw how to wrk wid dis the auto mode is also advise is dat dnt go for brand name niko canon etc...and panasonic is not a small brand... but people do thnk lyk dis...

 pros :
*16m:21x ,10m:26x ,5m:36x ,3m:48.3x you can increase it upto 84x
*ccd image sensor
*you can set aperture, shutter speed & ISO
*manual mode is also great
*macro mode is awesome
cons :
*you can't use the zoom in video mode
*it takes more time to focus
*the images not clear(blurred when you zoom) when you increase more than 400 ISO

if you are a beginner go for it guys it will not disappoint u anyway
