Data loss from a PC, laptop, memory card, or an iPod can have serious implications. The gravity of the issue is directly proportional to the kind of data you have lost. There are two ways to address this problem. You can either recreate the data, or recover the lost data. Recreating the data will depend on the complexity, or the kind of data that you have lost. For example, to a professional photographer recreating Raw image files will not be an acceptable option, since he cannot recreate the scenarios again.

What are Raw image files?

Raw image files refer to unprocessed or minimally processed data. Digital cameras, image scanners and motion picture film scanners use RAW image files. However, there is no single Raw file format, as different manufacturers use different raw formats specific to their model. Some of the common Raw image file formats include.bay (Casio), .3fr (Hasselblad), .cr2, .crw (Canon), .dcs, .dcr, .kdc (Kodak), .mef (Mamiya), .mrw (Minolta), .ptx, .pef (Pentax), .raf (Fuji) and.raw, .rw2 (Panasonic).

Advantages of Raw file formats

Some of the digital cameras allow you to shoot in both JPEG as well as Raw. When you shoot in JPEG, the images are processed using the in camera parameters, and you get a ready to print image. Whereas if you shoot using Raw, the images need to be further edited in a PC before you can view or print them. This feature, though time consuming (especially when you have hundreds of photos), lets you to change many of the parameters like contrast, sharpness, white balance, saturation etc of a photo, using a raw convertor. The raw file often referred to as the digital negative, can be converted to JPEG or TIFF, which enable you to store, print or further manage the image. Raw files have widespread application in professional photography as it allows storage of data without losing any data or the surroundings.

Losing Raw files from digital camera

Most of the digital cameras use memory cards such as secure digital (SD), multimedia card (MMC), Smart media or Miniature cards for storing data. Raw file can be edited only if you transfer it to a PC or laptop. Data loss can happen if

• the cable is pulled off while transferring data from the camera to PC or laptop
• you have accidentally deleted the data from the card
• you have formatted the card
• there is an improper shut down of the system due to power fluctuations or software malfunction
• the backup is corrupt or incorrect backup practices

Photo recovery software to recovering lost Raw, JPEG or TIFF files

Even after losing data from the memory card (SD, MMC, Smart media, Miniature), you can still recover it with a specialized photo recovery software. When data is deleted from the memory card, the data do not get erased completely, but the pointers to the data are erased. This makes the data inaccessible. Specialized photo recovery software is enabled with powerful algorithms to trace and recover such data.

However, if you use the camera to shoot more pictures after deleting data, the chances of recovering deleted or lost data is less. This is because the new pictures will over write the lost or deleted data. So, immediately after you lose data from a card

• do not use the card to store more data till you recover lost data
• remove the card from the camera and store it in a safe place to avoid using it further till you recover lost data

Tips for selecting photo recovery software

• While selecting photo recovery software, make sure that the software supports the raw format used by your camera.
• Select the file recovery software based on your operating systems. There are different software for Windows and Mac operating systems.
• Ensure that the software allows you to preview recovered files. Some of the recovery software will only display numbers against images. Without preview function, sorting through various image files can be very cumbersome.
• Make sure that the software comes with good customer support. Interact with the support team of the software company to make sure that they have mechanisms in place to handle customers' queries.
• Another important aspect you need to check is the payment processing channel used by the software company to ensure safe handling of your credit card details. Read company's website before ordering the product.

Creating a Fine Art Image and Stock Photo With Photoshop

Siri Stafford, my art director at the time, suggested this stock image for me. She asked me to make the image because she thought my specialty of using Photoshop to create conceptual stock images made me a logical choice for the job. I truly loved the idea; but what the heck would lightning hitting a tree really look like?

I turned to that technological development that has so radically changed the world of commercial photography...the internet. I simply typed in to Google's image search "lightning and tree". In just a few minutes I had found some obviously amateur images…but ones that were nonetheless stunning actual images of lightning hitting trees. Now I had something to work towards.

In my mind I pictured a lonely expanse of land with a single oak tree. A lightning bolt is caught as it hits the tree and illuminates the scene around it. The bolt travels down the trunk of the tree illuminating the leaves both from above and from behind at the same time. The sky is dark from storm clouds gathering at dusk.

Photographing the Oak Tree

There are many oak trees near my home in Marin County just across the Golden Gate Bridge from San Francisco. I scouted an open space nearby and found an oak tree that suited my needs. I photographed it just before noon with a slight back lighting. At that time I was still using film and captured the image with a Hasselblad medium format camera on Kodak Ektachrome film. Due to the steep slope of the land I couldn’t get the whole tree in the frame, despite my wide-angle lens, unless I turned the camera to a diagonal angle. In the same space I found and photographed an open expanse of land with a foreground of wild oats. From my files I found a photograph of cloudy skies and some distant low mountains—shot in Santa Fe, New Mexico, with a dirt road winding through the composition.

Getting a picture of a lightning strike

During a recent winter trip to Ladakh, a region in Kashmir often referred to as "Little Tibet" I got my lightning. It was long after dark and I was suffering both from altitude sickness and a case of the flue exacerbated by the extreme cold in my unheated guest room. A flash of light lit up the room and immediate rush of thunder testified to the closeness of the strike. Being as how I had never managed to shoot lightning (rarely do we get lightning in the San Francisco Bay Area), I managed to drag myself out from under the covers and grappled for my camera. With my head spinning from my physical condition I groggily shoved a roll of film in my F100, steadied on the windowsill, open the shutter and waited. Boom! Another flash. I repeated the procedure until I had shot a roll then climbed, shaking, back into my cot. As a stock photographer using Photoshop to composite so many of my images together, I am always on the look out for elements that I will be able to using in my stock composites. That effort finally paid off, I thought, as I scanned two of those lightning shots for this image. I made the scans using my Scanmate 5000 drum scanner and scanning the images at 100 megabytes each.

Using Adobe Photoshop to combine the images into a stock photo

I began assembling the image by using layer masks to paint together the landscape and cloud images. I merged the layers, duplicated the new layer, lightened it up with an adjustment layer of curves, and then used the layer masking to paint in the area to be "illuminated" by the lightning. The Tree was selected using the Color Range, magic wand, and lasso tools in conjunction with alpha channels. Making a selection of a tree with thousands of leaves is quite a challenge and in this case required not just the above sequence of operations, but also considerable time going in at 100% magnification and by hand, using the lasso tool, “cleaning up” even more of the tree selection. With the tree selected I copied and pasted it into the background. I duplicated the tree layer twice, darkened one with the curves and lightened the other. I then used layer masking to create the effect of light and dark areas where the lightning would be lighting up the leaves closest to the lightning bolt. Finally, I brought in the lightning bolt itself, pasted it in, and then setting the layer mode to “lighten” only. By setting the mode to “lighten” the pixels in the lightning image that were lighter than the underlying pixels of the rest of the image become the only ones visible…thus there was no need to “strip” the lightning bolt out of it’s dark background (I used the curves to darken the image enough to eliminate all but the lightning bolt itself). I used the liquefy brush to "fine-tune" the path of the bolt.

A timeless fine art image or stock photo

In the end I have not just a pretty picture, but a conceptual stock image that can be used to illustrate a number of marketing concepts. The image is exactly the kind of image that I strive to create, dramatic, useful and timeless.
