I read that in Lightroom 4 is possible to export reduced resolution raw files.

Does anybody know how to do it?

  • Hi Ghigo. This is different from a typical web forum — please add your answer as an answer rather than making it part of the question. – mattdm Apr 15 '12 at 18:04
  • mattdm, thanks for the tip. This is exactly what I wanted to do but until i get 100 point I can't answer my own question before 8 hours. – Ghigo Apr 15 '12 at 18:12
  • Ah, I see. Well, hopefully we'll see you back in a few more hours. :) – mattdm Apr 15 '12 at 18:21

Having done some research on the Adobe Lightroom help site I found this article on how to export to file.

I believe the feature you are referencing to is to do with

Enhanced DNG options

  • Resolution reduction via export provides the ability to share lower resolution versions of the original raw file without losing the capabilities offered by raw.

Thanks to Rob's links I found the solution.

Export the photo with the following settings:

  • Image format: DNG
  • Compatibility: Camera Raw 6.6 and later (required otherwise the lossy compression doesn't show)
  • Use Lossy Compression: Checked

For a Canon 7D raw files this process reduce the size at about the 25% of the original. I think I just found a good solution for bringing my photos with me on my laptop while keeping the original raws on my desktop computer.
