Posted: Thu Sep 20, 2012 12:58 pm Post subject: Lightroom 4 and EXIF-data |
|
|
Hello together,
I post this topic, to help out my good friend and A-D photographer Jerzy Maciaszek. His english is not that good and he is facing the following Problem:
When processing a picture with Lightroom 4, export it as a "jpg" to the disk, then uploading it to A-D.com, the EXIF-data will not show up. Export the file, after processing it with LR4, to PS-Elements and simply save the "jpg" to disk, upload it to the page, the EXIF-data will be shown.
Does anyone face the same problem or has a solution to that issue?
Any help would be appreciated!
greetings to all from Germany
Fritz

I shoot all my photos RAW to get the maximum quality out of my images.
All cameras that I know of use lossy JPEG compression so some fine detail is already lost before the images is even recorded to the memory card.
If you shoot RAW then that detail is preserved and you can make color corrections (such as changing the whitebalance) without any penalty. You can also take advantage of future improvements in the RAW-to-JPEG development algorithms, as was the case with the introduction of Adobe Lightroom V4 when it switched from the "2010" to the "2012" process.
I've attached two sample images comparing the two processes. The differences are subtle, my recommendation is to download the files to your computer and view them using Windows Photo Viewer and then using the left and right arrow keys to switch between them. The "2012" image is much clearer and seems to have a haze lifted from it. The colors are more vibrant and there are areas where there is more detail.

Hi all,
From the programmer's point of view, here are the two possible reasons that could cause missing EXIF data:
a. The software does not export EXIF data.
b. The softwar does export EXIF data but our exif code can not understand it.
Reason b is most likely. I use a open-source EXIF extraction code found on internet. It is a bit old, only support common digital cameras (Nikon, Canon, Kodak, to name a few), and limited data fields. So if Lightroom 4 use a different data format, then there's a good chance that EXIF data cannot be extracted.
If Fritz can post a Lightroom processed image here I can take a look.
