Camera equipment has long been attractive to the eyes of thieves. After all, it’s generally portable, pricey, and a piece of cake to sell through channels such as Craigslist. In Northern California, robbers have begun targeting photojournalists at gunpoint in order to snatch their gear.
Developer Trevor Sehrer, a Google engineer by day, has been working on a website that aims to help combat the theft of photography gear. It’s called Lenstag, and is an online equipment registry that makes it easier to report and track stolen cameras and lenses.
PTSD, or Post-Traumatic Stress Disorder, is a serious problem that affect a huge percentage of war veterans. A condition once associated most strongly with Vietnam War veterans, the Afghanistan and Iraq war have brought the condition back into the public eye with a vengeance.
According to the National Institute of Health, the VA estimates that approximately 31% of Vietnam vets, 10% of Desert Storm vets, 11% of Afghanistan vets and 20% of Iraq war veterans are affected. And while photography has been used to great effect to document PTSD in the past, one nurse at the VA in Palo Alto, California is using it to help treat veterans with the condition. Read more…
Sunday morning: time to survey the damage from last night’s party. As I walked around the apartment picking up empty beer bottles and cups, wiping up spills, and putting the furniture back, I remember having a distinct feeling that something was amiss. A quick survey of the apartment, and it hits me. My DSLR was missing.
Even as I frantically searched every nook and cranny of the apartment I knew the answer: someone had stolen my camera.
There’s an abandoned McDonalds in California that’s stuffed with 48,000 pounds of 70mm tape. These tapes contain never-before-seen ultra-high-res photographs of the moon shot by the Lunar Orbiter project 40 years ago. Rather than ship the film back to Earth, scientists decided to scan them on the spaceship, beam them back losslessly, and then record the data onto magnetic tape. Not wanting to reveal the precision of its spy satellites, the US government decided to mark the images as classified.
If you’ve ever deleted a photo by accident you probably already know about applications like DiskDigger that can go in and recover the image from the electronic beyond. This can come in really handy when an overzealous clicking finger accidentally erases several worthwhile pictures from your hard drive. Up until now, however, there was no way to perform the same search and rescue on your mobile device. Fortunately, DiskDigger for Android changes that. Read more…
Here’s a useful idea related to the memory card recovery tutorial we shared yesterday: if you’re ever confronted by someone who forces you to delete your photos (and our magical photographers’ rights gray card doesn’t work), go ahead and delete them! What most people don’t know is that deleted photos can easily be recovered afterward. Even photos on a memory card that’s formatted and completely wiped can usually be restored.
Last night my pastor emailed me telling me that he had accidentally deleted an entire folder of photographs off his Sony compact camera, and that Sony’s technical support informed him that it would cost $200-300 for them to recover the photos. After I got a hold of the memory card, I checked some of the recovery programs I’ve used in the past, but discovered that they now require paid licenses to actual do recovery (though analysis is free). I then stumbled across PhotoRec, a free and open source command-line application that’s bundled with TestDisk, something I’ve successfully used to regain access to inaccessible external hard drives.
In this post I’m going to show you how you can use PhotoRec to recover your photos if you’ve accidentally deleted them or formatted your memory card.
Do you know what to do if one of your prints gets damaged by water? If you living in a flood prone area (or are clumsy), it’d be good to know.
The Conservation Center for Art and Historic Artifacts (CCAHA) has an informative technical bulletin titled “Salvaging Photographs”, that provides a rundown on the response you should take to water damage.
One of the interesting tips is to freeze your prints to prevent further damage:
Freezing to help retard further deterioration by water or mold may be necessary if the materials cannot be treated immediately. Storage at low temperatures buys time in which to safely plan and organize the many steps needed to dry the affected materials and to prepare a rehabilitation site.
Vacuum freeze-drying can help you recover the prints:
In this method, photographic materials—either wet or frozen—are placed in a vacuum chamber. As the vacuum is pulled, a low heat source is introduced and the photographs are carefully dried at temperatures below freezing.
Some additional tips from the document:
- Keep immersion time to an absolute minimum
- Treat least stable items (i.e. prints rather than negatives) first
- Keep identifying information near the prints
- Never let the prints dry in contact with any surface, since it may stick permanently
If there’s any chance you might have to deal with recovering wet prints, this PDF would be a good thing to bookmark, save, or print out.
A few times in the past I’ve had to recover data from memory cards. Once it was a friend who accidentally reformatted the card and deleted hundreds of photographs from a recent vacation. Another time I accidentally deleted precious images from the memory card before I had backed them up. What I’ve learned though, is that in most cases, you can easily recover the data you fear was lost, even if you do something drastic such as reformat your card.
When you “delete” a photo from your memory card, it simply goes to that section of storage and marks it as “available” to be used again. The data of the original image is still there on your memory card, though the camera will not display it as an image. Thus, the most important thing you need to remember to do if you accidentally delete data is to stop using the memory card. This is because the only way for the data to truly become unrecoverable is if you delete it, then overwrite it with new data (or even blank data). Thus, to ensure that you can recover your deleted photo, you need to be sure to stop using your card immediately to ensure that nothing is written to that storage location on the card.
To do the actual recovery, you could take the card to a photography place and have a professional recover the data for you, but I’ve always relied on free software that can do the same thing. Here are some popular and free programs to try:
- Recover Files by Undelete & Unerase, Inc.
- Pandora Recovery by Pandora Corp.
- Digital Photo Recovery by Art Plus
Most of the good, safe, and free programs available for recovering photos are available only for Windows users. PhotoRescue is a popular program for Mac users, but costs $29.
Finally, the fact that data is so easily recoverable means that you need to be careful when selling things like computers and memory cards. Simply “deleting” data will not prevent what was on the card to fall into the wrong hands. If you’re selling a memory card that contained data you don’t want others to possibly recover, then be sure to overwrite the card completely, or look online for a program that helps you safely delete data.
