Richard Anderson and I will be doing a camera scanning workshop in New Orleans on the 28th of April (doors at 6:00 pm, program at 6:30). We will present techniques for creating reproduction-quality scans from film and negatives using a digital camera and inexpensive copy hardware. The program is free, but space is limited, so sign up early if you are interested.
This program is brought to you by ASMP, the New Orleans Photo Alliance, The US Library of Congress’s NDIIPP program, and Microsoft.
Adobe Labs has updated DNG conversion options in Lightroom, ACR, and the DNG Converter that offer some (possibly confusing) new options. You now have a preference pulldown for compatibility settings. What’s up with that? The short answer is that new functionality has been added to the DNG specification (and to the latest version of Camera Raw) that can do new tricks to the pictures.
For instance, there is now a way for Adobe (and others) to remove lens distortion from the image. Since this is a new function, it’s necessary to make a new version of the spec that details how to save and apply the instructions. One thing this enables is for cameras that don’t work well with the current DNG spec to now be supported. Check out Tom Hogarty’s blog to see the new camera support.
Some new DNGs that make use of these new tools won’t be fully compatible with all DNG applications. You can save them so that they will work with the older software, but they will lose some of their rawness. How the heck does one decide which to use?
In The DAM Book, Second Edition, I mention that you can use SuperDuper! as a program to do a validated transfer on Mac (in addition to Chronosync, the program I use). Some of my readers have contacted the software publisher and confirmed that it does NOT perform a validated transfer.
Sorry about the error, and thanks to readers Kevin Johnson and Tim Baker.
If you are wondering what the heck a validated transfer is, read about it at dpBestflow.org. (The movie embedded below is form the site, and shows the use of PC software SyncBack to do the process).
Here’s a quick tip to speed up Lightroom on an intel Mac. Select the program in the applications folder (single click), and then go to File>Get Info. In the General Panel, there is a checkbox to run the program in 32 bit mode. This is the default setting. Uncheck this box, and Lightroom will now run in 64 bit mode, speeding things up.
This is not available for G5 or earlier computers, nor for OS prior to 10.5.
On PC, you need to be running a 64 bit OS to install the 64 bit application.
