Choosing the Right Lens for Photography
May 27, 2009 Photography
Slowly, but surely, the worth of the fixed focal length lens (or prime lens) to the non-professional photographer is being eroded by the increasing perfection of zoom lens technology. The days when you packed your camera bag with trusty 28mm, 50mm, 85mm, 105mm, and even 180mm lenses are rapidly disappearing. Why bother when you can simply reach for something like Nikon’s all-purpose Nikkor 18-200mm DX VR zoom lens and know that you have both flexibility and optical speed at your fingertips?
The truth is that, while the range of focal lengths may be increasing within a single zoom lens, no all-purpose lens is ever likely to perform at the level of eqivalent prime lenses for its full range of focal lengths.
Zooms are engineered with a good deal more glass than is found in a prime lens, and because of this they “swallow” more light than the corresponding lens of the same focal length. Unless you are photographing under very bright light, the required increased shutter duration time of a zoom may make the difference between a good image, and one that is ruined by camera lens wobble.

Restore Deleted Pictures Erased From Any Memory Sd Card
Nov 26, 2008 Photography
We live in a world where digital cameras
have become something totally irreplaceable in our every day lives. We rely on them just like we do on mobile phones. We rely on them to take and store our pictures and precious moments in the camera memory cards.
However, what happens when these memory cards become damaged, corrupt or we accidentally format the sd card? If we delete these pictures from the memory card, is it all possible to restore them?
In most cases, you will be happy to know, it is highly unlikely that the files and data on those memory card is completely deleted and can be restored. Using some photo recovery tool, it is possible to restore your deleted or erased pictures with little fuss. You can even recover formatted pictures from sd card.
However, if you continue using your camera after formatting it and continue taking pictures the chances of successfully restoring ALL your pictures is slight. This is because the new pictures you have taken have now overwritten the older ones. Below are common situations you might find yourself in. You might want to restore deleted pictures if you have:
Accidentally pulled out the memory card while your digital camera is on
This is a common problem. You will find yourself in a situation where your memory card has become too damaged and corrupted. To restore your pictures, you will need a good picture recovery program.
“Media is not formatted would you like to format now?” or “Memory Card Not Formatted”
If you are getting this error, your pictures can still be recovered. This error again means that your memory card is corrupt. Don’t take any more photos and try a picture recovery program to get your pictures back. If you don’t need them, format your card and this should get rid of this error message.
Recover Pictures from SD Card after format
Even if you have formatted the card or used the Delete-All option, you can still retrieve your pictures after format if you act quickly. You can undelete your pictures because the digital camera wont overwrite that data immediately and just makes it available for use. If you have an Olympus camera that uses an xD card, once you re-format your xD card the pictures can’t be restored unfortunately.
As you can see, we are relying more and more on these memory card and digital cameras to record our special moments. However, it seems that our pictures are easier to get lost these days, corrupted or damaged than back in the film camera times. Memory cards can easily become corrupted and have a limited time span and there is always that dangerous “Delete All” button!
