New NVIDIA drivers will no longer support older CUDA GPUs

This just in from Adobe: "Just to alert you, NVIDIA is starting to discontinue CUDA support for some older GPUs in their new driver releases. If you are still using one of these older cards, and need GPU support for Adobe applications, do not update your drivers while you look into a purchasing a new card.

a little humor

A photon checks into a hotel and the bellhop asks him if he has any luggage. The photon replies, “No, I’m traveling light.”

Police Cameras Bring Problems of Their Own

This just in from the Wall Street Journal: "As more police agencies equip officers with body cameras in response to public pressure, authorities are discovering they create problems of their own: how to analyze, process and store the mountains of video each camera generates. Prosecutors in northern Colorado recently spent hours poring over a dozen videos captured by police wearing cameras. The

Correct Fisheye Distortion in FIVE

I've seen a lot of ADT installations using fisheye lenses lately. ADT must be having a sales promotion or something. One of the updates to FIVE in the last year is the Correct Fisheye filter, found in the Edit filter group. In the past, I would use the Undistort filter, but Correct Fisheye works a lot better / easier / faster on these low-end fisheye lenses I've been seeing. In the case
It looks like the transition to Amazon.com is finished and my book, Forensic Photoshop, is now available there exclusively. Paperback and hardcover options are both available for immediate shipping. As I've noted in the past, the book isn't based on a particular version of Photoshop. It's a workflow book ... what to do when, and why. As such, it's still relevant and informative for those

A bite mark matching advocacy group just conducted a study that discredits bite mark evidence

Here's an interesting article from the Washington Post about Forensic Odontology. Check out this quote, "the problem with bite mark analysis was never the lack of a flow chart.

Coursera courses reviewed

Last week, I finished the Coursera course, Visual Perception and the Brain. This course was taught by Dale Purves, MD, of Duke University and is one of the growing number of on-line non-credit courses offered by leading universities and noted professors around the world. I would recommend that DME analysts put this course on their to-do lists and watch for it to be offered again. There's a

Recovering image data from JPEG file fragments

This interesting paper was recently published by SPIE. SPIE is the international society of optics and photonics. "A new technique for recovering fragmented data files can retrieve elements of a JPEG compressed image even when the file's header is unavailable." "The most basic task of any file system is to manage and organize data in a storage volume. Each file in the store is allocated a list

LEVA Job Classification and Wage Study Results

This just in from LEVA: "The following Job Classification and Wage Study was completed in March of 2015 as part of a position audit. The survey focuses on particular job duties and functions performed by various analysts, technicians, and those who in some way handle digital multimedia evidence. All information contained in this report was volunteered by those who responded to the survey

How to: Open Exe Files on A Mac

I recently had an .Exe video file that wouldn't capture using any/all available PC tools. I tried Omnivore, FIVE, and a few others. Nothing. Thank God for my trusty old MacBook Pro. Here's an old video tutorial that's still relevant. It demonstrates using Wine / WineBottler to re-bundle the file into something that the Mac will recognize. Wine / WineBottler worked like a charm on my video.
