Lightroom jpeg export

  • August 31, 2017

I recently had to reinstall Adobe CC and now when I am exporting the jpegs from Lightroom they are much smaller in size than the full sized RAW Image.  I chose to export at the highest image quality, did NOT select to resize the image to fit, and chose resolution of 300 per inch.  The RAW image is 34 MB and the jpegs are ending up around 5 or 6 MB (they used to be 12-14).  Can anyone help with this? 

Thanks!

    And "selecting a resolution..."  is pointless for a digital image- Pixel dimensions are the all-important specification.

    (Only Print shops think they need a ppi resolution embedded in a photo file.)

    My analogy to explain 'ppi'  is a football team-  It does not matter if the team is crushed in the changing room or spread out over the field, it is still the same team (the same pixels).  'ppi' only affects the size of a print when you put those same pixels on paper.

      In addition to what Meredith already said: The file size of jpg's is dependent on the contents of an image and can heavily vary also due to the compression algorithms used.

      Of course, a jpg always is much smaller than a RAW which is absolutely normal.

      Hi Jessie,

      If you are not resizing then you would not be selecting a resolution you would only be selecting to export to jpeg.

      There is a check mark also available that you might have checked that has a file size limit. It might be what is the culprit.

      I am wondering if either you really are resizing on the export by adding in the resolution or if you have a file size limit.

      Meredith
