Recover Deleted Photos... even RAW files!
There are quite a few programs available to recover deleted photos but surprisingly few of these are designed to recover Camera RAW files. RAW files are image files saved in a format unique to a certain brand of camera. Nikon has their own format as does Canon, Olympus, Minolta and every high end camera maker. when you accidentally delete files stored on a camera smart card from one of these cameras or from the internal memory of one of these an ordinary data recvoery program cannot find them. You must use software that specifically addresses the proprietary file extensions.

Advanced Digital Photo Recovery Software - Techniques
Since the introduction of compact digital camera, flash memory cards have become hot selling commodity. However, they are the largest contributor for the loss of data due to manufacturing defects also on the other hand logical causes for data loss are equal contributor, which includes human error (accidental deletion), virus attack, sabotage etc.
The most common digital image file formats are JPEG and TIFF. Widely used cameras support primarily jpeg files. Mostly photograph enthusiasts like to shoot in JPEG as this file format provides smaller image size, better image quality with various file compression options.
The most common reasons for the damage or loss for digital photo files are:
1. Accidentally deleting image file from the memory cards, when trying to access them over PC
2. Accidental formatting of entire memory card through OS (Windows, MAC etc)
3. Memory card errors
4. File transfer errors
The above mentioned problems are the most common data loss situations. However, lost/deleted photo files (JPEG or TIFF) can be recovered. It is possible to recover some or almost all the lost/deleted image files, if they are intact and are left on the storage device without getting overwritten.
Most people believe that once photos or files are deleted, they are permanently gone, which is incorrect. Digital images are stored on memory cards as a file. These files occupy a fixed blocks (disk space calculated as group of sectors) on memory cards. At the same time it is not essential that they would be stored in a sequential (contiguous) fashion.
When a files is deleted or the device is formatted, the space in which the image were stored never gets erased. Instead, space is marked as “free”, so that the OS knows it can write a new image there. This is why the image will no longer be recognized by the camera or computer, even though the image is still present on the storage device.
Few precautions we must follow
1. Remove the memory card (SD, XD etc) from your camera and put in a safe place.
2. Immediately stop saving pictures or files to this card.
Connect this memory card to a card reader and ensure that card is getting recognized by the system, if the media is getting recognized than use specialized photo recovery software, else you would need to send the media to a professional data recovery services company.
