Working with Lr on Two Machines

Posted in Lightroom on 3 December 2009 by jepoma

In my opinion, the best way to work with Lr on two machines has been put forth by johnbeardy in one of his many contributions (over 2180 posts and counting) to Adobe’s Lightrom discussion forum:

Create a smart collection – Edited in Last X Days. Select it, and Export as Catalog, including negatives. Take this to the other computer, and Import from Catalog to get it into the other computer’s catalogue (or just open it directly). Reverse the process for bringing stuff back.

I will soon implement this solution and will report on its merits in due time. I take this opportunity to thank johnbeardy for this and his many other useful insights.

Lr rendering of NEF – Example

Posted in Lightroom on 19 October 2009 by jepoma

As a fellow poster on Adobe’s Lightroom forum saw color effects very similar to those I observe in Lr’s rendition of NEF files and as requested by another poster, I decided to make available an example NEF and its in-camera-generated companion JPG (these come from a lightning-hunting series). To download right-clik on link and “Save link as …” (note that the NEF file has a jpeg extension which should be changed back to NEF – the jpeg extension is required by the upload procedure on WordPress).

Once you upload the NEF in Lr, you will note the brown-red hues on the clouds and around the lower-right roof which are hardly visible on the JPEG. The “Camera Neutral” camera profile makes it worse. The “Camera Standard” camera profile hardly changes it. Other profiles produce one of these two effects i.e. they also don’t remove the brown-red hue. At night one cannot use a color-checker card, so creating my own profile is out. Tweaking the NEF for about 20 minutes did not help, short of making it black-and-white. So, what do you guys say ?

Lightroom borderless printing woe

Posted in Lightroom on 18 October 2009 by jepoma

Since day one, I’ve been having problems printing exactly what I want to print when I print borderless. The following image shows the full photograph and, within the dotted line rectangle, what came out when I printed it from Lightroom in borderless mode:

I expected to loose somewhat at the top and bottom, as the photograph is taller than the target paper (5×7 in this case), but I certainly did not expect to loose left or right. How can I tell Lr to simply crop at the top and bottom, but leave the sides as they are ? If you know, please leave a comment.

Lightroom’s NEF weak point

Posted in Lightroom on 13 September 2009 by jepoma

Lightroom (Lr) does not seem to handle NEFs that well (see, for instance, Adobe’s Forums). In my case, I have chromatic aberration problems. Here are two examples (2:1 views) with the JPEG generated by the D700 above and the corresponding NEF below:

Note the clearly visible red/cyan chromatic aberration (CA) in the NEFs, which is only slightly visible in the JPEGs. The CA in the NEFs goes away with a -33 red/cyan correction in Lr. Using Adobe’s camera profiles does not help in this respect.

Anyone else seen this in Lr ? How about in Aperture ? And NX2 ?
