DNG Verification in Lightroom 5

I’ve been looking forward to the day this can be announced since 2007. In Lightroom 5, there is now a one-click solution to verify an entire collection of DNG files. It’s a really simple idea, with pretty huge ramifications from a data management standpoint. Interestingly, it’s nearly absent from any Adobe marketing materials for LR 5.

Read all about it after the jump.

DNG Verification

Near the bottom of Lightroom 5’s Library menu, is an item that lets you validate an entire collection of DNG files with a single click. It’s right below the “Find Missing” command. These two tools, when used together, offer excellent verification workflow.

You’re going to need a bigger boat…

I got my D800 today, and I feel a bit like Roy Scheider in Jaws after he saw the size of the shark.  The files that come out of this camera are huge and remarkably good.  The 36 megapixels are also pushing the envelope of all of the rest of my equipment.

Lenses
The camera is so sharp that it is showing focus falloff where my D700 did not. Even great modern lenses like the 14-24 are showing signs of image imperfections that I have never seen before.  I suppose I’ll need to test all of my lenses and see which ones are up to using on this camera.  I also expect that I’ll need to test them at all apertures.

There’s a potential limits of diffraction problem with this kind of pixel density.

Cards
I’m getting 175 images on an 8 GB CF card. That’s going to go quickly. I have a bunch of much larger SD cards (32 GB), but they are slower.  Again, it looks like I’ll be doing some testing here.  I want first to see if any of the cards will produce a slowdown in shooting speed as they struggle to keep up with the data writing. After that, I’ll want to see what download times are for the various cards.  This will certainly be important in the field.

Hard Drives
I’ll be filling these up much faster with 40-50 MB raw files (14 bit, lossless compressed). This will certainly mean new portable drives for my upcoming trip to China, as well as for any extended location shoot.  And the archive drives will also be filling up faster, so there’s another purchase there as well.

Computer
These files are big, and process slowly. I have a feeling I’m going to need as much speed as I can get. New iMac?  New Macbook Pro?  Not sure.

Web publishing technology
There’s also a need to be able to view these images over the web. Photoshop has come with something called Zoomify – linked here – that can help with this.  But there’s some new technology called Piqsure that does this with HTML5 in some pretty cool ways.  More on that soon.

Shutha.org is live

For the last couple of months, I’ve been working on a project to help African photographers put their photos and multimedia into the world marketplace. Shutha.org is a free online learning resource, geared to professionals and aspiring professionals in the Majority World.  It was funded by World Press Photo and the Dutch Postcode lottery.  The project was run by Dave and Rosanne Larsen at Africa Media Online.

There is a comprehensive set of learning resources here, including help for business basics, marketing, business practices, as well as technical information.  Dave, Rosane and Dominique LeRoux were in charge of the business, sales and marketing materials. D.J. Clark produced a great section on multimedia production, Graeme Cookson provides background on imaging technology, and I wrote about Lightroom and how to create a safe and cost-effective digital photo computer system.

The entire project will look familiar to those of you who have seen dpBestflow, since it is powered by the same Drupal software that used over there.  It’s hard for me to see how we could have created this project without the generous support of ASMP. They contributed the use of their Drupal customizations, and paid for the work by Context Solutions, the excellent development team that worked on the ASMP.org site as well as dpBestflow.org.

Here’s the first movie in the Lightroom lesson plan: it outlines some of the creative possibilities offered by Lightroom in image adjustment.  I’ll provide more background about the project, the material and the team in future posts.


This movie shows “before and after” examples of photographs adjusted in Lightroom. It is part of the extensive and free training resources on Shutha.org

Sustainable Economics for a Digital Planet

Here’s another item I picked up at the NDIPP partners meeting – a report by some pretty heavy organizations about the economics of digital preservation.

The organizations included: U.S. National Science Foundation, The Andrew W. Mellon Foundation, the U.S. Library of Congress, the U.K. Joint Information Systems Committee, the Electronic Records Archives Program of the National Archives and Records Administration, and the Council on Library and Information Resources.

SSD Drives coming of age

I’ve been waiting for solid state drives to start to live up to the expectations (speed, security, low power, adequate capacity, affordability) that the marketplace has.  According to Diglloyd, that day has arrived in the form of OWC Mercury Extreme SSD. This appears to be the first drive truly delivers (except maybe for affordability).

There are a couple of breakthroughs this drive offers.  First, some background, after the jump. Continue reading SSD Drives coming of age
