Digital camera, the most efficient way to take crystal clear digital pictures, uses memory cards to store pictures that you shoot. Memory cards are the electronic flash media storage devices, which do not contain any moving parts to store and retrieve digital data. They are re-recordable devices, which can hold data without the power, i.e. memory cards are non-volatile storage devices. These devices are more stable and reliable than traditional hard drives as they do not have any moving components. However, memory cards are not completely safe as they face various kinds of logical damages and file loss. In such situations, you need to use digital photo recovery applications to retrieve lost or inaccessible pictures.

Memory card logical corruption is generally indicated by strange behavior of memory card or by various error messages that occur when you try to access data from or store data to the card. The error messages may vary, depending upon the cause and type of logical damage. Some of the common error messages that occur while using a flash card, are as given below:

A Media Card has been inserted that contains errors

Card Error

Card has wrong format

Error 30 Format CF card before use

The Card cannot be used

Card Requires Formatting What Causes Memory Card Corruption?

The card corruption and file loss can be caused by various reasons, ranging from virus infection to memory card data structure corruption. The most frequent reasons of memory card logical corruption are:

Virus infection. Pulling out memory card while write process is going on. Power surges. Switching off the camera during write process. Memory card metadata structure corruption.

Along with the above reasons, you may also lose photos due to accidental deletion, memory card formatting, and other similar reasons.

In all such situations, a complete backup proves to be of great help to sort out this problem and perform photo recovery. Critical situations occur when the backup is not updated or it is not available at all. At this point, image recovery software come to your rescue.

The applications are powerful enough to methodically scan entire memory card and extract all lost, missing, or deleted files from it. The applications come equipped with interactive graphical user interface to offer easy picture recovery in all cases of photo loss.

Digital cameras have made it convenient to capture beautiful moments of life. You can retain the ephemeral memories of events gone by in the form of photos in various storage media including memory cards, memory sticks, hard drives, hard disks, and USBs. Being a Mac OS X user, you can share, organize and edit your photos by using iPhoto. This application by Apple enables you to manage photos, irrespective of the format, in an easier and simpler manner. However, you may face some occasional problems while transferring photos from a digital camera. If iPhoto crashes in the middle of a transfer process, photos may become inaccessible from the storage media. In such situations, you may be required to recover lost photos from an updated backup. However, if no backup is available, you can perform Mac photo recovery by using advanced digital photo recovery tools.

Sample this: You return from a marvelous vacation to picturesque Venice after capturing the beauty of the place in form of countless photos. One fine morning, you connect your card via card reader to your Mac computer and iPhoto starts transferring photos to the system. In between, iPhoto crashes, halting the transfer process. You try and access the pictures in your digital camera but fail to do so.

Grounds of the issue

The file system of the storage media suffered a damage when iPhoto application crashed in the middle of photo transfer process.

Resolution

In order to fix the issue and get hold of photos, you may need to observe the following steps:

· You must format the memory card in your camera once again so as to fix damaged file system · Use an updated backup to restore pictures on the formatted memory card · If you don't have a backup or if it doesn't fulfill your requirement, then you must use a digital photo recovery software.

These third-party perform Mac photo recovery from various storage media including memory cards, memory sticks, hard drives, USBs and other removable media by applying improved scanning algorithms.

Being embedded with simple and interactive graphical user interface, these utilities can be used by anybody and do not require any prior technical knowledge.

Stellar Phoenix Photo Recovery is a reliable and safe software which recovers lost, deleted or formatted photos in three simple steps viz select, scan and save. The Mac
photo recovery software is compatible with Mac OS X 10.6(Snow Leopard), 10.5 (Leopard), 10.4 (Tiger), and 10.3.9 (Panther).

Canon EOS Rebel T1i or Canon EOS-500D is the substitute of Canon's earlier Rebel XSi (also known as EOS-450D) digital camera. It is packed with all basic functionalities of its predecessor along with major improvements like, movie recording support in full HD mode, 15.1 MP CMOS sensor, higher resolution, and various other features that make it an exclusive choice by professional photographers. Canon EOS Rebel T1i features SD (Secure Digital
) and SDHC (Secure Digital High Capacity) support for recording images, audios, and movies and thus prospects of memory card corruption always survive. However, there are different Photo Recovery applications available but a Canon EOS Rebel T1i user is highly recommended to keep a copy of all vital files in order to avoid any post, data loss consequences of storage corruption.

SD or SDHC card corruption can be the direct result of various wrongdoings with the camera. This includes turning off the camera without letting the write operation to complete, capturing photos when camera is low in battery, using Canon EOS Rebel T1i 's continuous shooting mode when the storage is almost full, and so on.

For detail understanding of the concept, consider an instance when you use Canon EOS Rebel T1i camera in one of your family functions. To record multiple images of a single event, you capture photos so rapidly that you don't realize that camera might have not completed writing images before the next gets ready to be written. After this, when you click to access the photos, the card cannot be accessed and displays the below error message:

“Card cannot be accessed. Reinsert/change card or format card with camera”

This scenario indicates file system corruption that has resulted inaccessibility of memory card in Canon EOS Rebel T1i camera. Also, accidental file deletion is one of the common causes of digital data loss.

Irrespective of the cause, if you have a valid backup of files, you can safely reformat the card within the camera or restore the deleted pictures. But in other cases, you need a Digital Photo Recovery product that can recover those lost digital memories. Photo Recovery applications
are powerful programs that can rescue all images, sounds, and movie clips with few simple clicks.

Pinhole cameras are the most basic cameras. If you take a sophisticated still image camera and strip it of its features such as lens, zooming, automatic focus, flash, automatic exposure, etc., what you have left is the simplest unit that functions as a basic camera. It may sound primitive, but a pinhole camera is actually a very useful device. In fact, you can even build one yourself with a few readily available materials. If you have already built a pinhole camera yourself, here's how to use one:

Shooting with a pinhole camera Load your pinhole camera using a photographic paper (choose a quick-acting one) or a film. Do this using a safelight or a flashlight in a dark or semi-dark room. Photographic paper is not as sensitive as film, so you'll have to perform exposures of up to 2 minutes on it for sunny conditions. With film, you'll only need about 1 to 2 seconds.

Make sure the side of the paper where the emulsion is (the shiny part) faces the pinhole. You'll need to use tape to attach the film or paper to your camera.

Make sure the shutter is made from dark, opaque material. This will ensure correct exposure of your images later. If you prefer, you can build a viewfinder to make focusing on a subject easier.

Next, choose your subject. Make sure there is sufficient light available. If the subject is at least 5 feet or closer to you, slightly tilt the camera upward to adjust for parallax. If the subject is more than 5 feet away, keep the pinhole camera at a straight horizontal.

Now the shooting begins… Once you've chosen your subject, open the shutter flap to let in the light. Make sure the camera is still during the exposure or the photo won't come out right. If you prefer, you could use a tripod or any stable base to ensure that the camera is steady. Lift the cover of the pinhole and leave this open for the specific time you choose. Between exposures, make sure to keep the pinhole covered using black paper.

Picture development To process and print photos made from a pinhole camera, you will only have to follow the same procedures used for photo development. Take care to ensure that there is sufficient exposure so the negative turns out dark. Make the contact print from the paper. Once that's done, you now have your very own photograph captured using a pinhole camera.

Pinhole cameras require some patience to build. They also require more patience to use. They are not for the impatient drive-by hobbyist. However, if you know how to use them properly, they can reward you with some of the most memorable photographs you'll ever take.
